For example, `my-awesome-project`. - -Go to the directory that will be the parent of your project, and run the command with your project's name: - -```bash -copier copy https://github.com/fastapi/full-stack-fastapi-template my-awesome-project --trust -``` - -If you have `pipx` and you didn't install `copier`, you can run it directly: - -```bash -pipx run copier copy https://github.com/fastapi/full-stack-fastapi-template my-awesome-project --trust -``` - -**Note** the `--trust` option is necessary to be able to execute a [post-creation script](https://github.com/fastapi/full-stack-fastapi-template/blob/master/.copier/update_dotenv.py) that updates your `.env` files. - -### Input Variables - -Copier will ask you for some data, you might want to have at hand before generating the project. - -But don't worry, you can just update any of that in the `.env` files afterwards. - -The input variables, with their default values (some auto generated) are: - -- `project_name`: (default: `"FastAPI Project"`) The name of the project, shown to API users (in .env). -- `stack_name`: (default: `"fastapi-project"`) The name of the stack used for Docker Compose labels and project name (no spaces, no periods) (in .env). -- `secret_key`: (default: `"changethis"`) The secret key for the project, used for security, stored in .env, you can generate one with the method above. -- `first_superuser`: (default: `"admin@example.com"`) The email of the first superuser (in .env). -- `first_superuser_password`: (default: `"changethis"`) The password of the first superuser (in .env). -- `smtp_host`: (default: "") The SMTP server host to send emails, you can set it later in .env. -- `smtp_user`: (default: "") The SMTP server user to send emails, you can set it later in .env. -- `smtp_password`: (default: "") The SMTP server password to send emails, you can set it later in .env. -- `emails_from_email`: (default: `"info@example.com"`) The email account to send emails from, you can set it later in .env. -- `postgres_password`: (default: `"changethis"`) The password for the PostgreSQL database, stored in .env, you can generate one with the method above. -- `sentry_dsn`: (default: "") The DSN for Sentry, if you are using it, you can set it later in .env. ## Backend Development diff --git a/copier.yml b/copier.yml deleted file mode 100644 index f98e3fc861..0000000000 --- a/copier.yml +++ /dev/null @@ -1,100 +0,0 @@ -project_name: - type: str - help: The name of the project, shown to API users (in .env) - default: FastAPI Project - -stack_name: - type: str - help: The name of the stack used for Docker Compose labels (no spaces) (in .env) - default: fastapi-project - -secret_key: - type: str - help: | - 'The secret key for the project, used for security, - stored in .env, you can generate one with: - python -c "import secrets;

SQLModel Table Duplication + +**Challenge:** SQLModel doesn't allow duplicate table definitions with the same name in the SQLAlchemy metadata, causing errors during the migration to modular architecture. + +**Solution:** +- Temporarily use the legacy models from `app.models` in the new modules +- Add clear documentation about the transitional nature of these imports +- Plan for gradual migration of models once references to legacy models are removed + +Example: +```python +# app/modules/users/repository/user_repo.py +from app.models import User # Temporary import until full migration +``` + +### 2.

The new architecture improves code organization, maintainability, and testability while maintaining deployment simplicity. + +The implementation faced several challenges, particularly with SQLModel table definitions, circular dependencies, and FastAPI's dependency injection system. These challenges were addressed with careful design patterns and transitional approaches that maintain backward compatibility. + +As the codebase continues to evolve, the modular architecture will provide a strong foundation for future enhancements and potential extraction of modules into separate services if needed. \ No newline at end of file diff --git a/backend/app/alembic/env.py b/backend/app/alembic/env.py index 4ad67482d7..0205e04fbb 100755 --- a/backend/app/alembic/env.py +++ b/backend/app/alembic/env.py @@ -21,27 +21,23 @@ from app.core.logging import get_logger # noqa: E402 # Import all models -# Keep the legacy import for now +# Keep the legacy import for now - this is sufficient for initial migrations from app.models import * # noqa: F403, F401 -# Import models from modules -# Auth module models -try: - from app.modules.auth.domain.models import * # noqa: F403, F401 -except ImportError: - pass - -# Users module models -try: - from app.modules.users.domain.models import * # noqa: F403, F401 -except ImportError: - pass - -# Items module models -try: - from app.modules.items.domain.models import * # noqa: F403, F401 -except ImportError: - pass +# NOTE: During the transition to a modular architecture, we're only importing the +# legacy models to avoid table definition conflicts.

Use `list[str]` instead of `List[str]` (Python 3.9+) + - Use `dict[str, Any]` instead of `Dict[str, Any]` (Python 3.9+) + - Use `Optional[str]` instead of `str | None` for clarity + + ```python + # Good + def get_items(skip: int = 0, limit: int = 100) -> list[Item]: + """Get items with pagination.""" + return item_repo.get_multi(skip=skip, limit=limit) + + # Avoid + def get_items(skip: int = 0, limit: int = 100) -> List[Item]: + """Get items with pagination.""" + return item_repo.get_multi(skip=skip, limit=limit) + ``` + +### Docstrings + +1. **Docstring Style**: + - Use Google-style docstrings + - Include a brief description of the function + - Document parameters, return values, and exceptions + - Keep docstrings concise and focused + + ```python + def create_user(user_create: UserCreate) -> User: + """ + Create a new user. + + Args: + user_create: User creation data + + Returns: + Created user + + Raises: + ValueError: If user with the same email already exists + """ + # Implementation + ``` + +2. **Module Docstrings**: + - Include a docstring at the top of each module + - Describe the purpose and contents of the module + + ```python + """ + User repository module. + + This module provides data access for user-related operations. + """ + ``` + +3. **Class Docstrings**: + - Include a docstring for each class + - Describe the purpose and behavior of the class + + ```python + class UserRepository: + """ + Repository for user-related data access. + + This class provides methods for creating, reading, updating, + and deleting user records in the database. + """ + ``` + +### Naming Conventions + +1. **General Naming**: + - Use descriptive names that convey the purpose + - Avoid abbreviations unless they are widely understood + - Be consistent with naming across the codebase + +2. **Case Conventions**: + - `snake_case` for variables, functions, methods, and modules + - `PascalCase` for classes and type variables + - `UPPER_CASE` for constants + - `snake_case` for file names + + ```python + # Variables and functions + user_id = uuid.uuid4() + def get_user_by_email(email: str) -> Optional[User]: + pass + + # Classes + class UserRepository: + pass + + # Constants + MAX_USERS = 100 + ``` + +3. **Naming Patterns**: + - Prefix boolean variables and functions with `is_`, `has_`, `can_`, etc. + - Use plural names for collections (lists, dictionaries, etc.) + - Use singular names for individual items + + ```python + # Boolean variables + is_active = True + has_permission = False + + # Collections + users = [user1, user2, user3] + + # Individual items + user = users[0] + ``` + +### Code Structure + +1. **Function Length**: + - Keep functions short and focused on a single task + - Aim for functions that are less than 20 lines + - Extract complex logic into separate functions + +2. **Line Length**: + - Keep lines under 88 characters (Black default) + - Use line breaks for long expressions + - Use parentheses to group long expressions + + ```python + # Good + result = ( + very_long_function_name( + long_argument1, + long_argument2, + long_argument3, + ) + ) + + # Avoid + result = very_long_function_name(long_argument1, long_argument2, long_argument3) + ``` + +3. **Whitespace**: + - Use 4 spaces for indentation (no tabs) + - Add a blank line between logical sections of code + - Add a blank line between function and class definitions + +### Error Handling + +1. **Exception Types**: + - Use specific exception types rather than generic ones + - Create custom exceptions for domain-specific errors + - Document exceptions in docstrings + + ```python + class UserNotFoundError(Exception): + """Raised when a user is not found.""" + pass + + def get_user_by_id(user_id: uuid.UUID) -> User: + """ + Get user by ID. + + Args: + user_id: User ID + + Returns: + User + + Raises: + UserNotFoundError: If user not found + """ + user = user_repo.get_by_id(user_id) + if not user: + raise UserNotFoundError(f"User with ID {user_id} not found") + return user + ``` + +2. **Error Messages**: + - Include relevant information in error messages + - Make error messages actionable + - Use consistent error message formats + + ```python + # Good + raise ValueError(f"User with email {email} already exists") + + # Avoid + raise ValueError("User exists") + ``` + +## Module-Specific Guidelines + +### Domain Models + +1. **Model Structure**: + -

Define an event class in the module's `domain/events.py` file: + +```python +from app.core.events import EventBase + +class MyEvent(EventBase): + event_type: str = "my.event" + # Add event properties here + + def publish(self) -> None: + from app.core.events import publish_event + publish_event(self) +``` + +2. Publish the event from a service: + +```python +event = MyEvent(property1="value1", property2="value2") +event.publish() +``` + +### Subscribing to Events + +To subscribe to events: + +1. Create an event handler in a module's services directory: + +```python +from app.core.events import event_handler +from other_module.domain.events import OtherEvent + +@event_handler("other.event") +def handle_other_event(event: OtherEvent) -> None: + # Handle the event + pass +``` + +2. Import the handler in the module's `__init__.py` to register it. + +For more details, see the [Event System Documentation](./MODULAR_MONOLITH_IMPLEMENTATION.md#event-system-implementation). + ## Email Templates The email templates are in `./backend/app/email-templates/`. Here, there are two directories: `build` and `src`. The `src` directory contains the source files that are used to build the final email templates. The `build` directory contains the final email templates that are used by the application. diff --git a/backend/TEST_PLAN.md b/backend/TEST_PLAN.md new file mode 100644 index 0000000000..8e8409c4d4 --- /dev/null +++ b/backend/TEST_PLAN.md @@ -0,0 +1,300 @@ +# Test Plan + +This document outlines the test plan for the modular monolith architecture. + +## Test Types + +### 1.

This presents a challenge for Alembic, which needs to be aware of all models to generate migrations correctly. + +## Current Approach + +During the transition to a fully modular architecture, we're using a hybrid approach: + +1. **Legacy Table Models**: We continue to import table models (with `table=True`) from `app.models` to avoid duplicate table definitions. +2. **Non-Table Models**: We import non-table models (without `table=True`) from their respective modules. + +## Generating Migrations + +To generate a migration: + +```bash +# From the project root directory +alembic revision --autogenerate -m "description_of_changes" +``` + +## Applying Migrations + +To apply migrations: + +```bash +# Apply all pending migrations +alembic upgrade head + +# Apply a specific number of migrations +alembic upgrade +1 + +# Rollback a specific number of migrations +alembic downgrade -1 +``` + +## Future Approach + +Once all model references have been updated to use the modular structure, we'll update the Alembic environment to import table models from their respective modules. + +The transition plan is: + +1. Update all code to use the modular imports +2. Remove the legacy models from `app.models` +3. Uncomment the table model definitions in each module +4. Update the Alembic environment to import from modules + +## Handling Module-Specific Migrations + +For module-specific migrations that don't affect the database schema (e.g., data migrations), you can create empty migrations: + +```bash +alembic revision -m "data_migration_for_module_x" +``` + +Then edit the generated file to include your custom migration logic. + +## Best Practices + +1. **Run Tests After Migrations**: Always run tests after applying migrations to ensure the application still works. +2. **Keep Migrations Small**: Make small, focused changes to make migrations easier to understand and troubleshoot. +3. **Document Complex Migrations**: Add comments to explain complex migration logic. +4. **Version Control**: Always commit migration files to version control. + +## Troubleshooting + +If you encounter issues with Alembic: + +1. **Import Errors**: Ensure all models are properly imported in `env.py`. +2. **Duplicate Tables**: Check for duplicate table definitions (models with the same `__tablename__`). +3. **Missing Dependencies**: Ensure all required packages are installed. +4. **Python Path**: Make sure the Python path includes the application root directory. + +================ +File: backend/app/alembic/script.py.mako +================ +"""${message} + +Revision ID: ${up_revision} +Revises: ${down_revision | comma,n} +Create Date: ${create_date} + +""" +from alembic import op +import sqlalchemy as sa +import sqlmodel.sql.sqltypes +${imports if imports else ""} + +# revision identifiers, used by Alembic. +revision = ${repr(up_revision)} +down_revision = ${repr(down_revision)} +branch_labels = ${repr(branch_labels)} +depends_on = ${repr(depends_on)} + + +def upgrade(): + ${upgrades if upgrades else "pass"} + + +def downgrade(): + ${downgrades if downgrades else "pass"} + +================ +File: backend/app/email-templates/build/new_account.html +================ +

Use `list[str]` instead of `List[str]` (Python 3.9+) + - Use `dict[str, Any]` instead of `Dict[str, Any]` (Python 3.9+) + - Use `Optional[str]` instead of `str | None` for clarity + + ```python + # Good + def get_items(skip: int = 0, limit: int = 100) -> list[Item]: + """Get items with pagination.""" + return item_repo.get_multi(skip=skip, limit=limit) + + # Avoid + def get_items(skip: int = 0, limit: int = 100) -> List[Item]: + """Get items with pagination.""" + return item_repo.get_multi(skip=skip, limit=limit) + ``` + +### Docstrings + +1. **Docstring Style**: + - Use Google-style docstrings + - Include a brief description of the function + - Document parameters, return values, and exceptions + - Keep docstrings concise and focused + + ```python + def create_user(user_create: UserCreate) -> User: + """ + Create a new user. + + Args: + user_create: User creation data + + Returns: + Created user + + Raises: + ValueError: If user with the same email already exists + """ + # Implementation + ``` + +2. **Module Docstrings**: + -

Include a docstring for each class + - Describe the purpose and behavior of the class + + ```python + class UserRepository: + """ + Repository for user-related data access. + + This class provides methods for creating, reading, updating, + and deleting user records in the database. + """ + ``` + +### Naming Conventions + +1. **General Naming**: + - Use descriptive names that convey the purpose + - Avoid abbreviations unless they are widely understood + - Be consistent with naming across the codebase + +2. **Case Conventions**: + - `snake_case` for variables, functions, methods, and modules + - `PascalCase` for classes and type variables + - `UPPER_CASE` for constants + - `snake_case` for file names + + ```python + # Variables and functions + user_id = uuid.uuid4() + def get_user_by_email(email: str) -> Optional[User]: + pass + + # Classes + class UserRepository: + pass + + # Constants + MAX_USERS = 100 + ``` + +3. **Naming Patterns**: + - Prefix boolean variables and functions with `is_`, `has_`, `can_`, etc. + - Use plural names for collections (lists, dictionaries, etc.) + - Use singular names for individual items + + ```python + # Boolean variables + is_active = True + has_permission = False + + # Collections + users = [user1, user2, user3] + + # Individual items + user = users[0] + ``` + +### Code Structure + +1. **Function Length**: + - Keep functions short and focused on a single task + - Aim for functions that are less than 20 lines + - Extract complex logic into separate functions + +2. **Line Length**: + - Keep lines under 88 characters (Black default) + -

Create a function that takes the event as a parameter +2. Decorate the function with `@event_handler("event.type")` +3. Import the handler in the module's `__init__.py` to register it + +Example: + +```python +@event_handler("user.created") +def handle_user_created(event: UserCreatedEvent) -> None: + """Handle user created event.""" + logger.info(f"User created: {event.user_id}") + # Handle the event... +``` + +## Event Naming Conventions + +Events should be named using the format `{entity}.{action}`: + +- `user.created` +- `user.updated` +- `user.deleted` +- `item.created` +- `item.updated` +- `item.deleted` +- `email.sent` +- `password.reset` + +## Best Practices + +### Event Design + +- **Keep Events Simple**: Events should contain only the data needed by handlers +- **Include IDs**: Always include entity IDs to allow handlers to fetch more data if needed +- **Use Meaningful Names**: Event names should clearly indicate what happened +- **Version Events**: Consider adding version information for long-lived events + +### Event Handlers + +- **Keep Handlers Focused**: Each handler should do one thing +- **Handle Errors Gracefully**: Errors in one handler shouldn't affect others +- **Avoid Circular Events**: Be careful not to create circular event chains +- **Document Dependencies**: Clearly document which events a module depends on + +### Testing + +- **Test Event Publishing**: Verify that events are published when expected +- **Test Event Handlers**: Test handlers in isolation with mock events +- **Test End-to-End**: Test the full event flow in integration tests + +## Real-World Examples + +### User Registration Flow + +1.

Backend + +## Requirements + +* [Docker](https://www.docker.com/). +* [uv](https://docs.astral.sh/uv/) for Python package and environment management. + +## Docker Compose + +Start the local development environment with Docker Compose following the guide in [../development.md](../development.md). + +## General Workflow + +By default, the dependencies are managed with [uv](https://docs.astral.sh/uv/), go there and install it. + +From `./backend/` you can install all the dependencies with: + +```console +$ uv sync +``` + +Then you can activate the virtual environment with: + +```console +$ source .venv/bin/activate +``` + +Make sure your editor is using the correct Python virtual environment, with the interpreter at `backend/.venv/bin/python`. + +## Modular Monolith Architecture + +This project follows a modular monolith architecture, which organizes the codebase into domain-specific modules while maintaining the deployment simplicity of a monolith. + +### Module Structure + +Each module follows this structure: + +``` +app/modules/{module_name}/ +├── __init__.py # Module initialization +├── api/ # API layer +│ ├── __init__.py +│ ├── dependencies.py # Module-specific dependencies +│ └── routes.py # API endpoints +├── domain/ # Domain layer +│ ├── __init__.py +│ ├── events.py # Domain events +│ └── models.py # Domain models +├── repository/ # Data access layer +│ ├── __init__.py +│ └── {module}_repo.py # Repository implementation +└── services/ # Business logic layer + ├── __init__.py + └── {module}_service.py # Service implementation +``` + +### Available Modules + +- **Auth**: Authentication and authorization +- **Users**: User management +- **Items**: Item management +- **Email**: Email sending and templates + +### Working with Modules + +To add functionality to an existing module, locate the appropriate layer (API, domain, repository, or service) and make your changes there. + +To create a new module, follow the structure above and register it in `app/api/main.py`. + +For more details, see the [Modular Monolith Implementation](./MODULAR_MONOLITH_IMPLEMENTATION.md) document. + +### Adding New Features + +When adding new features to the application: + +- Add SQLModel models in the appropriate module's `domain/models.py` file +- Add API endpoints in the module's `api/routes.py` file +- Implement business logic in the module's `services/` directory +- Create repositories for data access in the module's `repository/` directory +- Define domain events in the module's `domain/events.py` file when needed + +## VS Code + +There are already configurations in place to run the backend through the VS Code debugger, so that you can use breakpoints, pause and explore variables, etc. + +The setup is also already configured so you can run the tests through the VS Code Python tests tab. + +## Docker Compose Override + +During development, you can change Docker Compose settings that will only affect the local development environment in the file `docker-compose.override.yml`. + +The changes to that file only affect the local development environment, not the production environment. So, you can add "temporary" changes that help the development workflow. + +For example, the directory with the backend code is synchronized in the Docker container, copying the code you change live to the directory inside the container. That allows you to test your changes right away, without having to build the Docker image again. It should only be done during development, for production, you should build the Docker image with a recent version of the backend code. But during development, it allows you to iterate very fast. + +There is also a command override that runs `fastapi run --reload` instead of the default `fastapi run`. It starts a single server process (instead of multiple, as would be for production) and reloads the process whenever the code changes. Have in mind that if you have a syntax error and save the Python file, it will break and exit, and the container will stop. After that, you can restart the container by fixing the error and running again: + +```console +$ docker compose watch +``` + +There is also a commented out `command` override, you can uncomment it and comment the default one. It makes the backend container run a process that does "nothing", but keeps the container alive. That allows you to get inside your running container and execute commands inside, for example a Python interpreter to test installed dependencies, or start the development server that reloads when it detects changes. + +To get inside the container with a `bash` session you can start the stack with: + +```console +$ docker compose watch +``` + +and then in another terminal, `exec` inside the running container: + +```console +$ docker compose exec backend bash +``` + +You should see an output like: + +```console +root@7f2607af31c3:/app# +``` + +that means that you are in a `bash` session inside your container, as a `root` user, under the `/app` directory, this directory has another directory called "app" inside, that's where your code lives inside the container: `/app/app`. + +There you can use the `fastapi run --reload` command to run the debug live reloading server. + +```console +$ fastapi run --reload app/main.py +``` + +...it will look like: + +```console +root@7f2607af31c3:/app# fastapi run --reload app/main.py +``` + +and then hit enter. That runs the live reloading server that auto reloads when it detects code changes. + +Nevertheless, if it doesn't detect a change but a syntax error, it will just stop with an error. But as the container is still alive and you are in a Bash session, you can quickly restart it after fixing the error, running the same command ("up arrow" and "Enter"). + +...this previous detail is what makes it useful to have the container alive doing nothing and then, in a Bash session, make it run the live reload server. + +## Backend tests + +To test the backend run: + +```console +$ bash ./scripts/test.sh +``` + +The tests run with Pytest, modify and add tests to `./backend/app/tests/`. + +If you use GitHub Actions the tests will run automatically. + +### Test running stack + +If your stack is already up and you just want to run the tests, you can use: + +```bash +docker compose exec backend bash scripts/tests-start.sh +``` + +That `/app/scripts/tests-start.sh` script just calls `pytest` after making sure that the rest of the stack is running. If you need to pass extra arguments to `pytest`, you can pass them to that command and they will be forwarded. + +For example, to stop on first error: + +```bash +docker compose exec backend bash scripts/tests-start.sh -x +``` + +### Test Coverage + +When the tests are run, a file `htmlcov/index.html` is generated, you can open it in your browser to see the coverage of the tests. + +## Migrations + +As during local development your app directory is mounted as a volume inside the container, you can also run the migrations with `alembic` commands inside the container and the migration code will be in your app directory (instead of being only inside the container). So you can add it to your git repository. + +Make sure you create a "revision" of your models and that you "upgrade" your database with that revision every time you change them. As this is what will update the tables in your database. Otherwise, your application will have errors. + +* Start an interactive session in the backend container: + +```console +$ docker compose exec backend bash +``` + +* Alembic is configured to import models from their respective modules in the modular architecture + +* After changing a model (for example, adding a column), inside the container, create a revision, e.g.: + +```console +$ alembic revision --autogenerate -m "Add column last_name to User model" +``` + +* For more details on working with Alembic in the modular architecture, see the [Modular Monolith Implementation](./MODULAR_MONOLITH_IMPLEMENTATION.md#alembic-migration-environment) document. + +* Commit to the git repository the files generated in the alembic directory. + +* After creating the revision, run the migration in the database (this is what will actually change the database): + +```console +$ alembic upgrade head +``` + +If you don't want to use migrations at all, uncomment the lines in the file at `./backend/app/core/db.py` that end in: + +```python +SQLModel.metadata.create_all(engine) +``` + +and comment the line in the file `scripts/prestart.sh` that contains: + +```console +$ alembic upgrade head +``` + +If you don't want to start with the default models and want to remove them / modify them, from the beginning, without having any previous revision, you can remove the revision files (`.py` Python files) under `./backend/app/alembic/versions/`. And then create a first migration as described above. + +## Event System + +The project includes an event system for communication between modules. This allows for loose coupling while maintaining clear communication paths. + +### Publishing Events + +To publish an event from a module: + +1. Define an event class in the module's `domain/events.py` file: + +```python +from app.core.events import EventBase + +class MyEvent(EventBase): + event_type: str = "my.event" + # Add event properties here + + def publish(self) -> None: + from app.core.events import publish_event + publish_event(self) +``` + +2. Publish the event from a service: + +```python +event = MyEvent(property1="value1", property2="value2") +event.publish() +``` + +### Subscribing to Events + +To subscribe to events: + +1. Create an event handler in a module's services directory: + +```python +from app.core.events import event_handler +from other_module.domain.events import OtherEvent + +@event_handler("other.event") +def handle_other_event(event: OtherEvent) -> None: + # Handle the event + pass +``` + +2. Import the handler in the module's `__init__.py` to register it. + +For more details, see the [Event System Documentation](./MODULAR_MONOLITH_IMPLEMENTATION.md#event-system-implementation). + +## Email Templates + +The email templates are in `./backend/app/email-templates/`. Here, there are two directories: `build` and `src`. The `src` directory contains the source files that are used to build the final email templates. The `build` directory contains the final email templates that are used by the application. + +Before continuing, ensure you have the [MJML extension](https://marketplace.visualstudio.com/items?itemName=attilabuti.vscode-mjml) installed in your VS Code. + +Once you have the MJML extension installed, you can create a new email template in the `src` directory. After creating the new email template and with the `.mjml` file open in your editor, open the command palette with `Ctrl+Shift+P` and search for `MJML: Export to HTML`. This will convert the `.mjml` file to a `.html` file and now you can save it in the build directory. + +================ +File: backend/TEST_PLAN.md +================ +# Test Plan + +This document outlines the test plan for the modular monolith architecture. + +## Test Types + +### 1.

You can check the logs to monitor it. + +To check the logs, run (in another terminal): + +```bash +docker compose logs +``` + +To check the logs of a specific service, add the name of the service, e.g.: + +```bash +docker compose logs backend +``` + +## Local Development + +The Docker Compose files are configured so that each of the services is available in a different port in `localhost`. + +For the backend and frontend, they use the same port that would be used by their local development server, so, the backend is at `http://localhost:8000` and the frontend at `http://localhost:5173`. + +This way, you could turn off a Docker Compose service and start its local development service, and everything would keep working, because it all uses the same ports. + +For example, you can stop that `frontend` service in the Docker Compose, in another terminal, run: + +```bash +docker compose stop frontend +``` + +And then start the local frontend development server: + +```bash +cd frontend +npm run dev +``` + +Or you could stop the `backend` Docker Compose service: + +```bash +docker compose stop backend +``` + +And then you can run the local development server for the backend: + +```bash +cd backend +fastapi dev app/main.py +``` + +## Docker Compose in `localhost.tiangolo.com` + +When you start the Docker Compose stack, it uses `localhost` by default, with different ports for each service (backend, frontend, adminer, etc). + +When you deploy it to production (or staging), it will deploy each service in a different subdomain, like `api.example.com` for the backend and `dashboard.example.com` for the frontend. + +In the guide about [deployment](deployment.md) you can read about Traefik, the configured proxy. That's the component in charge of transmitting traffic to each service based on the subdomain. + +If you want to test that it's all working locally, you can edit the local `.env` file, and change: + +```dotenv +DOMAIN=localhost.tiangolo.com +``` + +That will be used by the Docker Compose files to configure the base domain for the services. + +Traefik will use this to transmit traffic at `api.localhost.tiangolo.com` to the backend, and traffic at `dashboard.localhost.tiangolo.com` to the frontend. + +The domain `localhost.tiangolo.com` is a special domain that is configured (with all its subdomains) to point to `127.0.0.1`. This way you can use that for your local development. + +After you update it, run again: + +```bash +docker compose watch +``` + +When deploying, for example in production, the main Traefik is configured outside of the Docker Compose files. For local development, there's an included Traefik in `docker-compose.override.yml`, just to let you test that the domains work as expected, for example with `api.localhost.tiangolo.com` and `dashboard.localhost.tiangolo.com`. + +## Docker Compose files and env vars + +There is a main `docker-compose.yml` file with all the configurations that apply to the whole stack, it is used automatically by `docker compose`. + +And there's also a `docker-compose.override.yml` with overrides for development, for example to mount the source code as a volume. It is used automatically by `docker compose` to apply overrides on top of `docker-compose.yml`. + +These Docker Compose files use the `.env` file containing configurations to be injected as environment variables in the containers. + +They also use some additional configurations taken from environment variables set in the scripts before calling the `docker compose` command. + +After changing variables, make sure you restart the stack: + +```bash +docker compose watch +``` + +## The .env file + +The `.env` file is the one that contains all your configurations, generated keys and passwords, etc. + +Depending on your workflow, you could want to exclude it from Git, for example if your project is public. In that case, you would have to make sure to set up a way for your CI tools to obtain it while building or deploying your project. + +One way to do it could be to add each environment variable to your CI/CD system, and updating the `docker-compose.yml` file to read that specific env var instead of reading the `.env` file. + +## Pre-commits and code linting + +we are using a tool called [pre-commit](https://pre-commit.com/) for code linting and formatting. + +When you install it, it runs right before making a commit in git. This way it ensures that the code is consistent and formatted even before it is committed. + +You can find a file `.pre-commit-config.yaml` with configurations at the root of the project. + +#### Install pre-commit to run automatically + +`pre-commit` is already part of the dependencies of the project, but you could also install it globally if you prefer to, following [the official pre-commit docs](https://pre-commit.com/). + +After having the `pre-commit` tool installed and available, you need to "install" it in the local repository, so that it runs automatically before each commit. + +Using `uv`, you could do it with: + +```bash +❯ uv run pre-commit install +pre-commit installed at .git/hooks/pre-commit +``` + +Now whenever you try to commit, e.g. with: + +```bash +git commit +``` + +...pre-commit will run and check and format the code you are about to commit, and will ask you to add that code (stage it) with git again before committing. + +Then you can `git add` the modified/fixed files again and now you can commit. + +#### Running pre-commit hooks manually + +you can also run `pre-commit` manually on all the files, you can do it using `uv` with: + +```bash +❯ uv run pre-commit run --all-files +check for added large files..............................................Passed +check toml...............................................................Passed +check yaml...............................................................Passed +ruff.....................................................................Passed +ruff-format..............................................................Passed +eslint...................................................................Passed +prettier.................................................................Passed +``` + +## URLs + +The production or staging URLs would use these same paths, but with your own domain. + +### Development URLs + +Development URLs, for local development. + +Frontend: http://localhost:5173 + +Backend: http://localhost:8000 + +Automatic Interactive Docs (Swagger UI): http://localhost:8000/docs + +Automatic Alternative Docs (ReDoc): http://localhost:8000/redoc + +Adminer: http://localhost:8080 + +Traefik UI: http://localhost:8090 + +MailCatcher: http://localhost:1080 + +### Development URLs with `localhost.tiangolo.com` Configured + +Development URLs, for local development. + +Frontend: http://dashboard.localhost.tiangolo.com + +Backend: http://api.localhost.tiangolo.com + +Automatic Interactive Docs (Swagger UI): http://api.localhost.tiangolo.com/docs + +Automatic Alternative Docs (ReDoc): http://api.localhost.tiangolo.com/redoc + +Adminer: http://localhost.tiangolo.com:8080 + +Traefik UI: http://localhost.tiangolo.com:8090 + +MailCatcher: http://localhost.tiangolo.com:1080 + +================ +File: docker-compose.override.yml +================ +services: + + #

Stops the server if it was started by the script + +### Client Utilities + +The BlackboxClient provides an interface for interacting with the API: + +```python +# Create a client +client = BlackboxClient() + +# Create a user +signup_response, user_data = client.sign_up( + email="test@example.com", + password="testpassword123", + full_name="Test User" +) + +# Login to get a token +login_response = client.login("test@example.com", "testpassword123") + +# The token is automatically stored and used in subsequent requests +user_profile = client.get("/api/v1/users/me") + +# Create an item +item_response = client.create_item("Test Item", "Test Description") +item_id = item_response.json()["id"] + +# Update an item +update_response = client.put(f"/api/v1/items/{item_id}", json_data={ + "title": "Updated Item" +}) + +# Delete an item +client.delete(f"/api/v1/items/{item_id}") +``` + +## Test Categories + +### API Contract Tests + +Verify that API endpoints adhere to their expected contracts: +- Response schemas +- Status codes +- Validation rules + +```python +def test_user_signup_contract(client): + # Test user signup returns the expected response structure + response, _ = client.sign_up( + email=f"test-{uuid.uuid4()}@example.com", + password="testpassword123", + full_name="Test User" + ) + + result = response.json() + verify_user_object(result) # Check schema fields exist + + # Verify validation errors + invalid_response, _ = client.sign_up(email="not-an-email", password="testpassword123") + assert_validation_error(invalid_response) +``` + +### User Lifecycle Tests + +Verify complete end-to-end user flows: + +```python +def test_complete_user_lifecycle(client): + # Create a user + signup_response, credentials = client.sign_up() + + # Login + client.login(credentials["email"], credentials["password"]) + + # Create an item + item_response = client.create_item("Test Item") + item_id = item_response.json()["id"] + + # Update the item + client.put(f"/api/v1/items/{item_id}", json_data={"title": "Updated Item"}) + + # Delete the item + client.delete(f"/api/v1/items/{item_id}") + + # Delete the user + client.delete("/api/v1/users/me") + + # Verify user is deleted by trying to login again + new_client = BlackboxClient() + login_response = new_client.login(credentials["email"], credentials["password"]) + assert login_response.status_code != 200 +``` + +### Authorization Tests + +Verify that authorization rules are enforced: + +```python +def test_resource_ownership_protection(client): + # Create two users + user1_client = BlackboxClient() + user1_client.create_and_login_user() + + user2_client = BlackboxClient() + user2_client.create_and_login_user() + + # User1 creates an item + item_response = user1_client.create_item("User1 Item") + item_id = item_response.json()["id"] + + # User2 attempts to access User1's item + user2_get_response = user2_client.get(f"/api/v1/items/{item_id}") + assert user2_get_response.status_code == 404, "User2 should not see User1's item" +``` + +## Test Execution Plan + +### Pre-Refactoring Phase + +1. Run the complete test suite against the current architecture +2. Establish a baseline of expected responses and behaviors +3. Create a test report documenting the current behavior + +### During Refactoring Phase + +1. After each module refactoring, run the relevant subset of tests +2. Verify that the refactored module maintains the same external behavior +3. Document any differences or issues encountered + +### Post-Refactoring Phase + +1. Run the complete test suite against the fully refactored architecture +2. Compare results with the pre-refactoring baseline +3. Verify all tests pass with the same results as before refactoring +4. Create a final test report documenting the comparison + +## Dependencies and Setup + +The tests require the following: + +1. httpx: `pip install httpx` +2. pytest: `pip install pytest` +3. A running FastAPI server (started automatically by the test script if not running) +4. The superuser credentials in environment variables (for admin tests) + +## Continuous Integration Integration + +Add the blackbox tests to the CI/CD pipeline to ensure they run on every pull request: + +```yaml +# .github/workflows/backend-tests.yml (example) +name: Backend Tests + +jobs: + blackbox-tests: + runs-on: ubuntu-latest + + services: + postgres: + image: postgres:13 + env: + POSTGRES_USER: postgres + POSTGRES_PASSWORD: postgres + POSTGRES_DB: app_test + ports: + - 5432:5432 + options: >- + --health-cmd pg_isready + --health-interval 10s + --health-timeout 5s + --health-retries 5 + + steps: + - uses: actions/checkout@v3 + + - name: Set up Python + uses: actions/setup-python@v4 + with: + python-version: '3.10' + + - name: Install dependencies + run: | + python -m pip install --upgrade pip + cd backend + pip install -e . + pip install pytest pytest-html httpx + + - name: Run blackbox tests + run: | + cd backend + bash scripts/run_blackbox_tests.sh + + - name: Upload test results + uses: actions/upload-artifact@v3 + with: + name: test-reports + path: backend/test-reports/ +``` + +## Conclusion + +This blackbox testing strategy ensures that the external behavior of the API remains consistent throughout the refactoring process. By focusing exclusively on HTTP interactions without any knowledge of implementation details, these tests provide the most reliable validation that the refactoring does not introduce changes in behavior from an external client's perspective. + +================ +File: backend/Dockerfile +================ +FROM python:3.10 + +ENV PYTHONUNBUFFERED=1 + +WORKDIR /app/ + +# Install uv +# Ref: https://docs.astral.sh/uv/guides/integration/docker/#installing-uv +COPY --from=ghcr.io/astral-sh/uv:0.5.11 /uv /uvx /bin/ + +# Place executables in the environment at the front of the path +# Ref: https://docs.astral.sh/uv/guides/integration/docker/#using-the-environment +ENV PATH="/app/.venv/bin:$PATH" + +# Compile bytecode +# Ref: https://docs.astral.sh/uv/guides/integration/docker/#compiling-bytecode +ENV UV_COMPILE_BYTECODE=1 + +# uv Cache +# Ref: https://docs.astral.sh/uv/guides/integration/docker/#caching +ENV UV_LINK_MODE=copy + +# Install dependencies +# Ref: https://docs.astral.sh/uv/guides/integration/docker/#intermediate-layers +RUN --mount=type=cache,target=/root/.cache/uv \ + --mount=type=bind,source=uv.lock,target=uv.lock \ + --mount=type=bind,source=pyproject.toml,target=pyproject.toml \ + uv sync --frozen --no-install-project + +ENV PYTHONPATH=/app + +COPY ./scripts /app/scripts + +COPY ./pyproject.toml ./uv.lock ./alembic.ini /app/ + +COPY ./app /app/app + +# Sync the project +# Ref: https://docs.astral.sh/uv/guides/integration/docker/#intermediate-layers +RUN --mount=type=cache,target=/root/.cache/uv \ + uv sync + +CMD ["fastapi", "run", "--workers", "4", "app/main.py"] + +================ +File: docker-compose.yml +================ +services: + + db: + image: postgres:17 + restart: always + healthcheck: + test: ["CMD-SHELL", "pg_isready -U ${POSTGRES_USER} -d ${POSTGRES_DB}"] + interval: 10s + retries: 5 + start_period: 30s + timeout: 10s + volumes: + -

SQLModel Table Duplication + +**Challenge:** SQLModel doesn't allow duplicate table definitions with the same name in the SQLAlchemy metadata, which required careful planning during the implementation of the modular architecture. + +**Solution:** +- Define table models in their respective domain modules +- Ensure consistent table naming across the application +- Use a centralized Alembic configuration that imports all models + +Example: +```python +# app/modules/users/domain/models.py +class User(UserBase, BaseModel, table=True): + """Database model for a user.""" + __tablename__ = "user" + + id: uuid.UUID = Field(default_factory=uuid.uuid4, primary_key=True) +``` + +### 2. Circular Dependencies + +**Challenge:** Module interdependencies led to circular imports, causing import errors during application startup. + +**Solution:** +- Use local imports (inside functions) instead of module-level imports for cross-module references +- Adopt a clear initialization order for modules +- Implement a modular dependency injection system + +Example: +```python +def init_users_module(app: FastAPI) -> None: + # Import here to avoid circular imports + from app.modules.users.api.routes import router as users_router + + # Include the users router in the application + app.include_router(users_router, prefix=settings.API_V1_STR) +``` + +### 3. FastAPI Dependency Injection Issues + +**Challenge:** Encountered errors with FastAPI's dependency injection system when using annotated types and default values together. + +**Solution:** +- Use consistent parameter ordering in route functions: + 1. Security dependencies (e.g., `current_user`) first + 2. Path and query parameters + 3. Request body parameters + 4. Service/dependency injections with default values + +Example: +```python +@router.get("/items/", response_model=ItemsPublic) +def read_items( + current_user: CurrentUser, # Security dependency first + skip: int = 0, # Query parameters + limit: int = 100, + item_service: ItemService = Depends(get_item_service), # Service dependency last +) -> Any: + # Function implementation +``` + +### 4. Alembic Migration Environment + +**Challenge:** Alembic needed to recognize models from all modules in the modular structure. + +**Solution:** +- Configure Alembic's `env.py` to import models from all modules +- Create a systematic approach for model discovery +- Document the process for adding new models to the migration environment + +## Module Structure Implementation + +Each domain module follows this layered architecture: + +``` +app/modules/{module_name}/ +├── __init__.py # Module initialization and router export +├── api/ # API routes and controllers +│ ├── __init__.py +│ └── routes.py +├── dependencies.py # FastAPI dependencies for injection +├── domain/ # Domain models and business rules +│ ├── __init__.py +│ └── models.py +├── repository/ # Data access layer +│ ├── __init__.py +│ └── {module}_repo.py +└── services/ # Business logic + ├── __init__.py + └── {module}_service.py +``` + +## Module Initialization Flow + +The initialization flow for modules has been implemented as follows: + +1. Main application creates a FastAPI instance +2. `app/api/main.py` initializes API routes from all modules +3. Each module has an initialization function (e.g., `init_users_module`) +4. Module initialization registers routes, sets up event handlers, and performs startup tasks + +Example: +```python +def init_api_routes(app: FastAPI) -> None: + # Include the API router + app.include_router(api_router, prefix=settings.API_V1_STR) + + # Initialize all modules + init_auth_module(app) + init_users_module(app) + init_items_module(app) + init_email_module(app) + + logger.info("API routes initialized") +``` + +## Shared Components + +Common functionality is implemented in the `app/shared` directory: + +1. **Base Models** (`app/shared/models.py`) + - Standardized timestamp and UUID handling + - Common model attributes and behaviors + +2. **Exceptions** (`app/shared/exceptions.py`) + - Domain-specific exception types + - Standardized error responses + +## Cross-Cutting Concerns + +1. **Event System** (`app/core/events.py`) + - Pub/sub pattern for communication between modules + - Event handlers and subscribers + - Domain events for cross-module communication + +2. **Logging** (`app/core/logging.py`) + - Centralized logging configuration + - Module-specific loggers + +3. **Database Access** (`app/core/db.py`) + - Base repository implementation + - Session management + - Transaction handling + +## Best Practices Identified + +1. **Consistent Dependency Injection** + - Use FastAPI's Depends for all dependencies + - Order dependencies consistently in route functions + - Use typed dependencies with Annotated when possible + +2. **Module Isolation** + - Keep domains separate and cohesive + - Use interfaces for cross-module communication + - Minimize direct dependencies between modules + +3. **Error Handling** + - Use domain-specific exceptions + - Convert exceptions to HTTP responses at the API layer + - Provide clear error messages and appropriate status codes + +4. **Documentation** + - Document transitional patterns clearly + - Add comments explaining architecture decisions + - Provide usage examples for module components + +## Event System Implementation + +The event system is a critical component of the modular monolith architecture, enabling loose coupling between modules while maintaining clear communication paths. It follows a publish-subscribe (pub/sub) pattern where events are published by one module and can be handled by any number of subscribers in other modules. + +### Core Components + +1. **EventBase Class** (`app/core/events.py`) + - Base class for all events in the system + - Provides common structure and behavior for events + - Includes event_type field to identify event types + +2. **Event Publishing** + - `publish_event()` function for broadcasting events + - Handles both synchronous and asynchronous event handlers + - Provides error isolation (errors in one handler don't affect others) + +3. **Event Subscription** + - `subscribe_to_event()` function for registering handlers + - `@event_handler` decorator for easy handler registration + - Support for multiple handlers per event type + +### Domain Events + +Domain events represent significant occurrences within a specific domain. They are implemented as Pydantic models extending the EventBase class: + +```python +# app/modules/users/domain/events.py +from app.core.events import EventBase, publish_event + +class UserCreatedEvent(EventBase): + """Event emitted when a new user is created.""" + event_type: str = "user.created" + user_id: uuid.UUID + email: str + full_name: Optional[str] = None + + def publish(self) -> None: + """Publish this event to all registered handlers.""" + publish_event(self) +``` + +### Event Handlers + +Event handlers are functions that respond to specific event types. They can be defined in any module: + +```python +# app/modules/email/services/email_event_handlers.py +from app.core.events import event_handler +from app.modules.users.domain.events import UserCreatedEvent + +@event_handler("user.created") +def handle_user_created_event(event: UserCreatedEvent) -> None: + """Handle user created event by sending welcome email.""" + email_service = get_email_service() + email_service.send_new_account_email( + email_to=event.email, + username=event.email, + password="**********" # Password is masked in welcome email + ) +``` + +### Module Integration + +Each module can both publish events and subscribe to events from other modules: + +1. **Publishing Events** + - Domain services publish events after completing operations + - Events include relevant data but avoid exposing internal implementation details + +2. **Subscribing to Events** + - Modules import event handlers at initialization + - Event handlers are registered automatically via the `@event_handler` decorator + - No direct dependencies between publishing and subscribing modules + +### Best Practices + +1. **Event Naming** + - Use past tense verbs (e.g., "user.created" not "user.create") + - Follow domain.event_name pattern (e.g., "user.created", "item.updated") + - Be specific about what happened + +2. **Event Content** + - Include only necessary data in events + - Use IDs rather than full objects when possible + - Ensure events are serializable + +3. **Handler Implementation** + - Keep handlers focused on a single responsibility + - Handle errors gracefully within handlers + - Consider performance implications for synchronous handlers + +### Example: User Registration Flow + +1. User service creates a new user in the database +2. User service publishes a `UserCreatedEvent` +3. Email module's handler receives the event +4. Email handler sends a welcome email to the new user +5. Other modules could also handle the same event for different purposes + +This approach decouples the user creation process from sending welcome emails, allowing each module to focus on its core responsibilities. + +## Future Work + +1. **Performance Optimization** + - Identify and optimize performance bottlenecks + - Implement caching strategies for frequently accessed data + - Optimize database queries and ORM usage + +2. **Enhanced Event System** + - Add support for asynchronous event processing + - Implement event persistence for reliability + - Create more comprehensive event monitoring and debugging tools + +3. **Module Configuration** + - Implement module-specific configuration settings + - Create a more flexible configuration system + - Support environment-specific module configurations + +4. **Testing Improvements** + - Expand test coverage for all modules + - Implement more comprehensive integration tests + - Add performance benchmarking tests + - Create unit tests for domain services and repositories + - Develop integration tests for module boundaries + - Implement end-to-end tests for complete flows + +## Conclusion + +The modular monolith architecture has been successfully implemented. The new architecture significantly improves code organization, maintainability, and testability while maintaining the deployment simplicity of a monolith. + +The implementation addressed several challenges, particularly with SQLModel table definitions, circular dependencies, and FastAPI's dependency injection system.

Create a function that takes the event as a parameter -2. Decorate the function with `@event_handler("event.type")` -3.

They can be defined in any module: - -```python -# app/modules/email/services/email_event_handlers.py -from app.core.events import event_handler -from app.modules.users.domain.events import UserCreatedEvent - -@event_handler("user.created") -def handle_user_created_event(event: UserCreatedEvent) -> None: - """Handle user created event by sending welcome email.""" - email_service = get_email_service() - email_service.send_new_account_email( - email_to=event.email, - username=event.email, - password="**********" # Password is masked in welcome email - ) -``` - -### Module Integration - -Each module can both publish events and subscribe to events from other modules: - -1. **Publishing Events** - - Domain services publish events after completing operations - - Events include relevant data but avoid exposing internal implementation details - -2. **Subscribing to Events** - - Modules import event handlers at initialization - - Event handlers are registered automatically via the `@event_handler` decorator - - No direct dependencies between publishing and subscribing modules - -### Best Practices - -1. **Event Naming** - - Use past tense verbs (e.g., "user.created" not "user.create") - - Follow domain.event_name pattern (e.g., "user.created", "item.updated") - - Be specific about what happened - -2. **Event Content** - - Include only necessary data in events - - Use IDs rather than full objects when possible - - Ensure events are serializable - -3. **Handler Implementation** - - Keep handlers focused on a single responsibility - - Handle errors gracefully within handlers - - Consider performance implications for synchronous handlers - -### Example: User Registration Flow - -1. User service creates a new user in the database -2. User service publishes a `UserCreatedEvent` -3. Email module's handler receives the event -4. Email handler sends a welcome email to the new user -5. Other modules could also handle the same event for different purposes - -This approach decouples the user creation process from sending welcome emails, allowing each module to focus on its core responsibilities. - -## Future Work - -1. **Performance Optimization** - - Identify and optimize performance bottlenecks - - Implement caching strategies for frequently accessed data - - Optimize database queries and ORM usage - -2. **Enhanced Event System** - - Add support for asynchronous event processing - - Implement event persistence for reliability - - Create more comprehensive event monitoring and debugging tools - -3. **Module Configuration** - - Implement module-specific configuration settings - - Create a more flexible configuration system - - Support environment-specific module configurations - -4. **Testing Improvements** - - Expand test coverage for all modules - - Implement more comprehensive integration tests - - Add performance benchmarking tests - - Create unit tests for domain services and repositories - - Develop integration tests for module boundaries - - Implement end-to-end tests for complete flows - -## Conclusion - -The modular monolith architecture has been successfully implemented. The new architecture significantly improves code organization, maintainability, and testability while maintaining the deployment simplicity of a monolith. - -The implementation addressed several challenges, particularly with SQLModel table definitions, circular dependencies, and FastAPI's dependency injection system. These challenges were overcome with careful design patterns and architectural decisions. - -The modular architecture provides a strong foundation for future enhancements and potential extraction of modules into separate microservices if needed.

-================ -File: backend/app/alembic/README -================ -Generic single-database configuration. - -================ -File: backend/app/alembic/README_MODULAR.md -================ -# Alembic in Modular Monolith Architecture - -This document explains how to use Alembic with the modular monolith architecture. - -## Overview - -In our modular monolith architecture, models are distributed across multiple modules. This presents a challenge for Alembic, which needs to be aware of all models to generate migrations correctly. - -## Current Approach - -During the transition to a fully modular architecture, we're using a hybrid approach: - -1. **Legacy Table Models**: We continue to import table models (with `table=True`) from `app.models` to avoid duplicate table definitions. -2. **Non-Table Models**: We import non-table models (without `table=True`) from their respective modules. - -## Generating Migrations - -To generate a migration: - -```bash -# From the project root directory -alembic revision --autogenerate -m "description_of_changes" -``` - -## Applying Migrations - -To apply migrations: - -```bash -# Apply all pending migrations -alembic upgrade head - -# Apply a specific number of migrations -alembic upgrade +1 - -# Rollback a specific number of migrations -alembic downgrade -1 -``` - -## Future Approach - -Once all model references have been updated to use the modular structure, we'll update the Alembic environment to import table models from their respective modules. - -The transition plan is: - -1. Update all code to use the modular imports -2. Remove the legacy models from `app.models` -3. Uncomment the table model definitions in each module -4. Update the Alembic environment to import from modules - -## Handling Module-Specific Migrations - -For module-specific migrations that don't affect the database schema (e.g., data migrations), you can create empty migrations: - -```bash -alembic revision -m "data_migration_for_module_x" -``` - -Then edit the generated file to include your custom migration logic. - -## Best Practices - -1. **Run Tests After Migrations**: Always run tests after applying migrations to ensure the application still works. -2. **Keep Migrations Small**: Make small, focused changes to make migrations easier to understand and troubleshoot. -3. **Document Complex Migrations**: Add comments to explain complex migration logic. -4. **Version Control**: Always commit migration files to version control. - -## Troubleshooting - -If you encounter issues with Alembic: - -1. **Import Errors**: Ensure all models are properly imported in `env.py`. -2. **Duplicate Tables**: Check for duplicate table definitions (models with the same `__tablename__`). -3. **Missing Dependencies**: Ensure all required packages are installed. -4. **Python Path**: Make sure the Python path includes the application root directory. - -================ -File: backend/app/alembic/script.py.mako -================ -"""${message} - -Revision ID: ${up_revision} -Revises: ${down_revision | comma,n} -Create Date: ${create_date} - -""" -from alembic import op -import sqlalchemy as sa -import sqlmodel.sql.sqltypes -${imports if imports else ""} - -# revision identifiers, used by Alembic. -revision = ${repr(up_revision)} -down_revision = ${repr(down_revision)} -branch_labels = ${repr(branch_labels)} -depends_on = ${repr(depends_on)} - - -def upgrade(): - ${upgrades if upgrades else "pass"} - - -def downgrade(): - ${downgrades if downgrades else "pass"} - -================ -File: backend/app/email-templates/build/new_account.html -================ -

-## Module Example - -The `module_example` directory demonstrates how to create a new module in the modular monolith architecture. It includes: - -- Module initialization -- Domain models and events -- Repository implementation -- Service implementation -- API routes -- Event handlers - -### Using the Example - -To use this example in a real project: - -1. Copy the `module_example` directory to `app/modules/your_module_name` -2. Rename all occurrences of "example" to your module name -3. Update the module initialization in `app/api/main.py` -4. Implement your business logic - -### Key Features Demonstrated - -- **Domain Models**: How to define domain models for your module -- **Events**: How to publish and subscribe to events -- **Repository Pattern**: How to implement data access -- **Service Layer**: How to implement business logic -- **API Routes**: How to expose functionality via REST API -- **Dependency Injection**: How to use FastAPI's dependency injection - -## Event System Example - -The example module demonstrates how to use the event system: - -- **Publishing Events**: See `services/example_service.py` for examples of publishing events -- **Subscribing to Events**: See `services/event_handlers.py` for an example of subscribing to events - -### Event Flow - -1. An event is published from a service (e.g., `ProductCreatedEvent`) -2. The event is processed by the event system -3. Any registered handlers for that event type are called - -## Best Practices Demonstrated - -- **Separation of Concerns**: Each layer has a specific responsibility -- **Domain-Driven Design**: Models and events are defined in the domain layer -- **Repository Pattern**: Data access is abstracted behind repositories -- **Service Layer**: Business logic is implemented in services -- **Dependency Injection**: Dependencies are injected rather than imported directly -- **Event-Driven Communication**: Modules communicate via events -

-================ -File: backend/CODE_STYLE_GUIDE.md -================ -# Code Style Guide - -This document outlines the code style guidelines for the modular monolith architecture. - -## General Principles - -1. **Consistency**: Follow consistent patterns throughout the codebase -2. **Readability**: Write code that is easy to read and understand -3. **Maintainability**: Write code that is easy to maintain and extend -4. **Testability**: Write code that is easy to test - -## Python Style Guidelines - -### Imports - -1. **Import Order**: - - Standard library imports first - - Third-party imports second - - Application imports third - - Sort imports alphabetically within each group - - ```python - # Standard library imports - import os - import uuid - from datetime import datetime - from typing import Any, Dict, List, Optional - - # Third-party imports - from fastapi import APIRouter, Depends, HTTPException, status - from pydantic import EmailStr - from sqlmodel import Session, select - - # Application imports - from app.core.config import settings - from app.core.logging import get_logger - from app.modules.users.domain.models import UserCreate, UserPublic - ``` - -2. **Import Style**: - - Use absolute imports rather than relative imports - - Import specific classes and functions rather than entire modules - - Avoid wildcard imports (`from module import *`) - - ```python - # Good - from app.core.config import settings - - # Avoid - from app.core import config - config.settings - - # Bad - from app.core.config import * - ``` - -### Type Hints - -1. **Use Type Hints**: - - Add type hints to all function parameters and return values - - Use `Optional` for parameters that can be `None` - - Use `Any` sparingly and only when necessary - - ```python - def get_user_by_id(user_id: uuid.UUID) -> Optional[User]: - """Get user by ID.""" - return user_repo.get_by_id(user_id) - ``` - -2. **Type Hint Style**: - - Use `list[str]` instead of `List[str]` (Python 3.9+) - - Use `dict[str, Any]` instead of `Dict[str, Any]` (Python 3.9+) - - Use `Optional[str]` instead of `str | None` for clarity - - ```python - # Good - def get_items(skip: int = 0, limit: int = 100) -> list[Item]: - """Get items with pagination.""" - return item_repo.get_multi(skip=skip, limit=limit) - - # Avoid - def get_items(skip: int = 0, limit: int = 100) -> List[Item]: - """Get items with pagination.""" - return item_repo.get_multi(skip=skip, limit=limit) - ``` - -### Docstrings - -1. **Docstring Style**: - - Use Google-style docstrings - - Include a brief description of the function - - Document parameters, return values, and exceptions - - Keep docstrings concise and focused - - ```python - def create_user(user_create: UserCreate) -> User: - """ - Create a new user. - - Args: - user_create: User creation data - - Returns: - Created user - - Raises: - ValueError: If user with the same email already exists - """ - # Implementation - ``` - -2. **Module Docstrings**: - - Include a docstring at the top of each module - - Describe the purpose and contents of the module - - ```python - """ - User repository module. - - This module provides data access for user-related operations. - """ - ``` - -3. **Class Docstrings**: - - Include a docstring for each class - - Describe the purpose and behavior of the class - - ```python - class UserRepository: - """ - Repository for user-related data access. - - This class provides methods for creating, reading, updating, - and deleting user records in the database. - """ - ``` - -### Naming Conventions - -1. **General Naming**: - - Use descriptive names that convey the purpose - - Avoid abbreviations unless they are widely understood - - Be consistent with naming across the codebase - -2. **Case Conventions**: - - `snake_case` for variables, functions, methods, and modules - - `PascalCase` for classes and type variables - - `UPPER_CASE` for constants - - `snake_case` for file names - - ```python - # Variables and functions - user_id = uuid.uuid4() - def get_user_by_email(email: str) -> Optional[User]: - pass - - # Classes - class UserRepository: - pass - - # Constants - MAX_USERS = 100 - ``` - -3. **Naming Patterns**: - - Prefix boolean variables and functions with `is_`, `has_`, `can_`, etc. - - Use plural names for collections (lists, dictionaries, etc.) - - Use singular names for individual items - - ```python - # Boolean variables - is_active = True - has_permission = False - - # Collections - users = [user1, user2, user3] - - # Individual items - user = users[0] - ``` - -### Code Structure - -1. **Function Length**: - - Keep functions short and focused on a single task - - Aim for functions that are less than 20 lines - - Extract complex logic into separate functions - -2. **Line Length**: - - Keep lines under 88 characters (Black default) - - Use line breaks for long expressions - - Use parentheses to group long expressions - - ```python - # Good - result = ( - very_long_function_name( - long_argument1, - long_argument2, - long_argument3, - ) - ) - - # Avoid - result = very_long_function_name(long_argument1, long_argument2, long_argument3) - ``` - -3. **Whitespace**: - - Use 4 spaces for indentation (no tabs) - - Add a blank line between logical sections of code - - Add a blank line between function and class definitions - -### Error Handling - -1. **Exception Types**: - - Use specific exception types rather than generic ones - - Create custom exceptions for domain-specific errors - - Document exceptions in docstrings - - ```python - class UserNotFoundError(Exception): - """Raised when a user is not found.""" - pass - - def get_user_by_id(user_id: uuid.UUID) -> User: - """ - Get user by ID. - - Args: - user_id: User ID - - Returns: - User - - Raises: - UserNotFoundError: If user not found - """ - user = user_repo.get_by_id(user_id) - if not user: - raise UserNotFoundError(f"User with ID {user_id} not found") - return user - ``` - -2. **Error Messages**: - - Include relevant information in error messages - - Make error messages actionable - - Use consistent error message formats - - ```python - # Good - raise ValueError(f"User with email {email} already exists") - - # Avoid - raise ValueError("User exists") - ``` - -## Module-Specific Guidelines - -### Domain Models - -1. **Model Structure**: - - Define base models with common properties - - Extend base models for specific use cases - - Use clear and consistent naming - - ```python - class UserBase(SQLModel): - """Base user model with common properties.""" - email: str = Field(unique=True, index=True, max_length=255) - is_active: bool = True - - class UserCreate(UserBase): - """Model for creating a user.""" - password: str = Field(min_length=8, max_length=40) - - class UserUpdate(UserBase): - """Model for updating a user.""" - email: Optional[str] = Field(default=None, max_length=255) - password: Optional[str] = Field(default=None, min_length=8, max_length=40) - ``` - -2. **Field Validation**: - - Add validation constraints to fields - - Document validation constraints in docstrings - - Use consistent validation patterns - - ```python - class UserCreate(UserBase): - """Model for creating a user.""" - password: str = Field( - min_length=8, - max_length=40, - description="User password (8-40 characters)", - ) - ``` - -### Repositories - -1. **Repository Methods**: - - Include standard CRUD methods (create, read, update, delete) - - Add domain-specific query methods as needed - - Use consistent naming and parameter patterns - - ```python - class UserRepository: - """Repository for user-related data access.""" - - def get_by_id(self, user_id: uuid.UUID) -> Optional[User]: - """Get user by ID.""" - return self.session.get(User, user_id) - - def get_by_email(self, email: str) -> Optional[User]: - """Get user by email.""" - statement = select(User).where(User.email == email) - return self.session.exec(statement).first() - ``` - -2. **Error Handling**: - - Raise specific exceptions for domain-specific errors - - Document exceptions in docstrings - - Handle database errors appropriately - - ```python - def create(self, user: User) -> User: - """ - Create new user. - - Args: - user: User to create - - Returns: - Created user - - Raises: - ValueError: If user with the same email already exists - """ - existing_user = self.get_by_email(user.email) - if existing_user: - raise ValueError(f"User with email {user.email} already exists") - - self.session.add(user) - self.session.commit() - self.session.refresh(user) - return user - ``` - -### Services - -1. **Service Methods**: - - Include business logic for domain operations - - Coordinate repository calls and other services - - Handle domain-specific validation and rules - - ```python - class UserService: - """Service for user-related operations.""" - - def create_user(self, user_create: UserCreate) -> User: - """ - Create a new user. - - Args: - user_create: User creation data - - Returns: - Created user - - Raises: - ValueError: If user with the same email already exists - """ - # Hash the password - hashed_password = get_password_hash(user_create.password) - - # Create the user - user = User( - email=user_create.email, - hashed_password=hashed_password, - is_active=user_create.is_active, - ) - - # Save the user - created_user = self.user_repo.create(user) - - # Publish event - event = UserCreatedEvent(user_id=created_user.id, email=created_user.email) - event.publish() - - return created_user - ``` - -2. **Event Publishing**: - - Publish domain events for significant state changes - - Include relevant information in events - - Document event publishing in docstrings - - ```python - def update_user(self, user_id: uuid.UUID, user_update: UserUpdate) -> User: - """ - Update user. - - Args: - user_id: User ID - user_update: User update data - - Returns: - Updated user - - Raises: - UserNotFoundError: If user not found - """ - # Get the user - user = self.user_repo.get_by_id(user_id) - if not user: - raise UserNotFoundError(f"User with ID {user_id} not found") - - # Update fields if provided - update_data = user_update.model_dump(exclude_unset=True) - for field, value in update_data.items(): - setattr(user, field, value) - - # Save the user - updated_user = self.user_repo.update(user) - - # Publish event - event = UserUpdatedEvent(user_id=updated_user.id) - event.publish() - - return updated_user - ``` - -### API Routes - -1. **Route Structure**: - - Group related routes in the same router - - Use consistent URL patterns - - Include appropriate HTTP methods and status codes - - ```python - @router.get("/", response_model=UsersPublic) - def read_users( - session: SessionDep, - current_user: CurrentUser, - user_service: UserService = Depends(get_user_service), - skip: int = 0, - limit: int = 100, - ) -> Any: - """ - Retrieve users. - - Args: - session: Database session - current_user: Current user - user_service: User service - skip: Number of records to skip - limit: Maximum number of records to return - - Returns: - List of users - """ - users = user_service.get_multi(skip=skip, limit=limit) - count = user_service.count() - return user_service.to_public_list(users, count) - ``` - -2. **Dependency Injection**: - - Use FastAPI's dependency injection system - - Create helper functions for common dependencies - - Document dependencies in docstrings - - ```python - def get_user_service(session: SessionDep) -> UserService: - """ - Get user service. - - Args: - session: Database session - - Returns: - User service - """ - user_repo = UserRepository(session) - return UserService(user_repo) - ``` - -3. **Error Handling**: - - Convert domain exceptions to HTTP exceptions - - Include appropriate status codes and error messages - - Document error responses in docstrings - - ```python - @router.get("/{user_id}", response_model=UserPublic) - def read_user( - user_id: uuid.UUID, - session: SessionDep, - current_user: CurrentUser, - user_service: UserService = Depends(get_user_service), - ) -> Any: - """ - Get user by ID. - - Args: - user_id: User ID - session: Database session - current_user: Current user - user_service: User service - - Returns: - User - - Raises: - HTTPException: If user not found - """ - try: - user = user_service.get_by_id(user_id) - return user_service.to_public(user) - except UserNotFoundError as e: - raise HTTPException(status_code=status.HTTP_404_NOT_FOUND, detail=str(e)) - ``` - -## Tools and Automation - -1. **Code Formatting**: - - Use [Black](https://black.readthedocs.io/) for code formatting - - Use [isort](https://pycqa.github.io/isort/) for import sorting - - Use [Ruff](https://github.com/charliermarsh/ruff) for linting - -2. **Type Checking**: - - Use [mypy](https://mypy.readthedocs.io/) for static type checking -

- Fix issues before committing code - -## Conclusion - -Following these code style guidelines will help maintain a consistent, readable, and maintainable codebase. Remember that the goal is to write code that is easy to understand, modify, and extend, not just code that works. - -================ -File: backend/EVENT_SYSTEM.md -================ -# Event System Documentation - -This document provides detailed information about the event system used in the modular monolith architecture. - -## Overview - -The event system enables loose coupling between modules by allowing them to communicate through events rather than direct dependencies. This approach has several benefits: - -- **Decoupling**: Modules don't need to know about each other's implementation details -- **Extensibility**: New functionality can be added by subscribing to existing events -- **Testability**: Event handlers can be tested in isolation -- **Maintainability**: Changes to one module don't require changes to other modules - -## Core Components - -### Event Base Class - -All events inherit from the `EventBase` class defined in `app/core/events.py`: - -```python -class EventBase(SQLModel): - """Base class for all events.""" - - event_type: str - created_at: datetime = Field(default_factory=datetime.utcnow) - - def publish(self) -> None: - """Publish the event.""" - from app.core.events import publish_event - publish_event(self) -``` - -### Event Registry - -The event system maintains a registry of event handlers in `app/core/events.py`: - -```python -# Event handler registry -_event_handlers: Dict[str, List[Callable]] = {} -``` - -### Event Handler Decorator - -Event handlers are registered using the `event_handler` decorator: - -```python -def event_handler(event_type: str) -> Callable: - """ - Decorator to register an event handler. - - Args: - event_type: Type of event to handle - - Returns: - Decorator function - """ - def decorator(func: Callable) -> Callable: - if event_type not in _event_handlers: - _event_handlers[event_type] = [] - _event_handlers[event_type].append(func) - logger.info(f"Registered handler {func.__name__} for event {event_type}") - return func - return decorator -``` - -### Event Publishing - -Events are published using the `publish_event` function: - -```python -def publish_event(event: EventBase) -> None: - """ - Publish an event. - - Args: - event: Event to publish - """ - event_type = event.event_type - logger.info(f"Publishing event {event_type}") - - if event_type in _event_handlers: - for handler in _event_handlers[event_type]: - try: - handler(event) - except Exception as e: - logger.error(f"Error handling event {event_type} with handler {handler.__name__}: {e}") - # Continue processing other handlers - else: - logger.info(f"No handlers registered for event {event_type}") -``` - -## Using the Event System - -### Defining Events - -To define a new event: - -1. Create a new class that inherits from `EventBase` -2. Define the `event_type` attribute -3. Add any additional attributes needed for the event -4. Implement the `publish` method - -Example: - -```python -class UserCreatedEvent(EventBase): - """Event published when a user is created.""" - event_type: str = "user.created" - user_id: uuid.UUID - email: str - - def publish(self) -> None: - """Publish the event.""" - from app.core.events import publish_event - publish_event(self) -``` - -### Publishing Events - -To publish an event: - -1. Create an instance of the event class -2. Call the `publish` method - -Example: - -```python -def create_user(self, user_create: UserCreate) -> User: - # Create user logic... - - # Publish event - event = UserCreatedEvent(user_id=user.id, email=user.email) - event.publish() - - return user -``` - -### Subscribing to Events - -To subscribe to an event: - -1. Create a function that takes the event as a parameter -2. Decorate the function with `@event_handler("event.type")` -3. Import the handler in the module's `__init__.py` to register it - -Example: - -```python -@event_handler("user.created") -def handle_user_created(event: UserCreatedEvent) -> None: - """Handle user created event.""" - logger.info(f"User created: {event.user_id}") - # Handle the event... -``` - -## Event Naming Conventions - -Events should be named using the format `{entity}.{action}`: - -- `user.created` -- `user.updated` -- `user.deleted` -- `item.created` -- `item.updated` -- `item.deleted` -- `email.sent` -- `password.reset` - -## Best Practices - -### Event Design - -- **Keep Events Simple**: Events should contain only the data needed by handlers -- **Include IDs**: Always include entity IDs to allow handlers to fetch more data if needed -- **Use Meaningful Names**: Event names should clearly indicate what happened -- **Version Events**: Consider adding version information for long-lived events - -### Event Handlers - -- **Keep Handlers Focused**: Each handler should do one thing -- **Handle Errors Gracefully**: Errors in one handler shouldn't affect others -- **Avoid Circular Events**: Be careful not to create circular event chains -- **Document Dependencies**: Clearly document which events a module depends on - -### Testing - -- **Test Event Publishing**: Verify that events are published when expected -- **Test Event Handlers**: Test handlers in isolation with mock events -- **Test End-to-End**: Test the full event flow in integration tests - -## Real-World Examples - -### User Registration Flow - -1. User registers via API -2. User service creates the user -3. User service publishes `UserCreatedEvent` -4. Email service handles `UserCreatedEvent` and sends welcome email -5. Analytics service handles `UserCreatedEvent` and logs the registration - -```python -# User service -def register_user(self, user_register: UserRegister) -> User: - # Create user - user = User( - email=user_register.email, - full_name=user_register.full_name, - hashed_password=get_password_hash(user_register.password), - ) - - created_user = self.user_repo.create(user) - - # Publish event - event = UserCreatedEvent(user_id=created_user.id, email=created_user.email) - event.publish() - - return created_user - -# Email service -@event_handler("user.created") -def send_welcome_email(event: UserCreatedEvent) -> None: - """Send welcome email to new user.""" - # Get user from database - user = user_repo.get_by_id(event.user_id) - - # Send email - email_service.send_email( - email_to=user.email, - subject="Welcome to our service", - template_type=EmailTemplateType.NEW_ACCOUNT, - template_data={"user_name": user.full_name}, - ) - -# Analytics service -@event_handler("user.created") -def log_user_registration(event: UserCreatedEvent) -> None: - """Log user registration for analytics.""" - analytics_service.log_event( - event_type="user_registration", - user_id=event.user_id, - timestamp=datetime.utcnow(), - ) -``` - -### Item Creation Flow - -1. User creates an item via API -2. Item service creates the item -3. Item service publishes `ItemCreatedEvent` -4. Notification service handles `ItemCreatedEvent` and notifies relevant users -5. Search service handles `ItemCreatedEvent` and indexes the item - -```python -# Item service -def create_item(self, item_create: ItemCreate, owner_id: uuid.UUID) -> Item: - # Create item - item = Item( - title=item_create.title, - description=item_create.description, - owner_id=owner_id, - ) - - created_item = self.item_repo.create(item) - - # Publish event - event = ItemCreatedEvent( - item_id=created_item.id, - title=created_item.title, - owner_id=created_item.owner_id, - ) - event.publish() - - return created_item - -# Notification service -@event_handler("item.created") -def notify_item_creation(event: ItemCreatedEvent) -> None: - """Notify relevant users about new item.""" - # Get owner's followers - followers = follower_repo.get_followers(event.owner_id) - - # Notify followers - for follower in followers: - notification_service.send_notification( - user_id=follower.id, - message=f"New item: {event.title}", - link=f"/items/{event.item_id}", - ) - -# Search service -@event_handler("item.created") -def index_item(event: ItemCreatedEvent) -> None: - """Index item in search engine.""" - # Get item from database - item = item_repo.get_by_id(event.item_id) - - # Index item - search_service.index_item( - id=str(item.id), - title=item.title, - description=item.description, - owner_id=str(item.owner_id), - ) -``` - -## Debugging Events - -To debug events, you can use the logger in `app/core/events.py`: - -```python -# Add this to your local development settings -import logging -logging.getLogger("app.core.events").setLevel(logging.DEBUG) -``` - -This will log detailed information about event publishing and handling. - -================ -File: backend/EXTENDING_ARCHITECTURE.md -================ -# Extending the Modular Monolith Architecture - -This guide explains how to extend the modular monolith architecture by adding new modules or enhancing existing ones. - -## Creating a New Module - -### 1.

Register the Module - -In `app/api/main.py`, import and initialize your module: - -```python -from app.modules.{module_name} import init_{module_name}_module - -def init_api_routes(app: FastAPI) -> None: - # ... existing code ... - - # Initialize your module - init_{module_name}_module(app) - - # ... existing code ... -``` - -### 4. Create Tests - -Create tests for your module in the `tests/modules/{module_name}/` directory, following the same structure as the module. - -## Enhancing Existing Modules - -To add functionality to an existing module: - -1. **Add Domain Models**: Add new models to the module's `domain/models.py` file. -2. **Add Repository Methods**: Add new methods to the module's repository. -3. **Add Service Methods**: Add new business logic to the module's service. -4. **Add API Endpoints**: Add new endpoints to the module's `api/routes.py` file. -5. **Add Tests**: Add tests for the new functionality. - -## Adding Cross-Module Communication - -To enable communication between modules: - -1. **Define Events**: Create event classes in the source module's `domain/events.py` file. -2. **Publish Events**: Publish events from the source module's services. -3. **Subscribe to Events**: Create event handlers in the target module's services. -4. **Register Handlers**: Import the handlers in the target module's `__init__.py` file. - -## Best Practices - -1. **Maintain Module Boundaries**: Keep module code within its directory structure. -2. **Use Dependency Injection**: Inject dependencies rather than importing them directly. -3. **Follow Layered Architecture**: Respect the layered architecture within each module. -4. **Document Your Code**: Add docstrings to all classes and methods. -5. **Write Tests**: Create tests for all new functionality. -6. **Use Events for Cross-Module Communication**: Avoid direct imports between modules. -

-### Module Structure - -Each module follows this structure: - -``` -app/modules/{module_name}/ -├── __init__.py # Module initialization -├── api/ # API layer -│ ├── __init__.py -│ ├── dependencies.py # Module-specific dependencies -│ └── routes.py # API endpoints -├── domain/ # Domain layer -│ ├── __init__.py -│ ├── events.py # Domain events -│ └── models.py # Domain models -├── repository/ # Data access layer -│ ├── __init__.py -│ └── {module}_repo.py # Repository implementation -└── services/ # Business logic layer - ├── __init__.py - └── {module}_service.py # Service implementation -``` - -### Available Modules - -- **Auth**: Authentication and authorization -- **Users**: User management -- **Items**: Item management -- **Email**: Email sending and templates - -### Working with Modules - -To add functionality to an existing module, locate the appropriate layer (API, domain, repository, or service) and make your changes there. - -To create a new module, follow the structure above and register it in `app/api/main.py`. - -For more details, see the [Modular Monolith Implementation](./MODULAR_MONOLITH_IMPLEMENTATION.md) document. - -### Adding New Features - -When adding new features to the application: - -- Add SQLModel models in the appropriate module's `domain/models.py` file -- Add API endpoints in the module's `api/routes.py` file -- Implement business logic in the module's `services/` directory -- Create repositories for data access in the module's `repository/` directory -- Define domain events in the module's `domain/events.py` file when needed - -## VS Code - -There are already configurations in place to run the backend through the VS Code debugger, so that you can use breakpoints, pause and explore variables, etc. - -The setup is also already configured so you can run the tests through the VS Code Python tests tab. - -## Docker Compose Override - -During development, you can change Docker Compose settings that will only affect the local development environment in the file `docker-compose.override.yml`. - -The changes to that file only affect the local development environment, not the production environment. So, you can add "temporary" changes that help the development workflow. - -For example, the directory with the backend code is synchronized in the Docker container, copying the code you change live to the directory inside the container. That allows you to test your changes right away, without having to build the Docker image again. It should only be done during development, for production, you should build the Docker image with a recent version of the backend code. But during development, it allows you to iterate very fast. - -There is also a command override that runs `fastapi run --reload` instead of the default `fastapi run`. It starts a single server process (instead of multiple, as would be for production) and reloads the process whenever the code changes. Have in mind that if you have a syntax error and save the Python file, it will break and exit, and the container will stop. After that, you can restart the container by fixing the error and running again: - -```console -$ docker compose watch -``` - -There is also a commented out `command` override, you can uncomment it and comment the default one. It makes the backend container run a process that does "nothing", but keeps the container alive. That allows you to get inside your running container and execute commands inside, for example a Python interpreter to test installed dependencies, or start the development server that reloads when it detects changes. - -To get inside the container with a `bash` session you can start the stack with: - -```console -$ docker compose watch -``` - -and then in another terminal, `exec` inside the running container: - -```console -$ docker compose exec backend bash -``` - -You should see an output like: - -```console -root@7f2607af31c3:/app# -``` - -that means that you are in a `bash` session inside your container, as a `root` user, under the `/app` directory, this directory has another directory called "app" inside, that's where your code lives inside the container: `/app/app`. - -There you can use the `fastapi run --reload` command to run the debug live reloading server. - -```console -$ fastapi run --reload app/main.py -``` - -...it will look like: - -```console -root@7f2607af31c3:/app# fastapi run --reload app/main.py -``` - -and then hit enter. That runs the live reloading server that auto reloads when it detects code changes. - -Nevertheless, if it doesn't detect a change but a syntax error, it will just stop with an error. But as the container is still alive and you are in a Bash session, you can quickly restart it after fixing the error, running the same command ("up arrow" and "Enter"). - -...this previous detail is what makes it useful to have the container alive doing nothing and then, in a Bash session, make it run the live reload server. - -## Backend tests - -To test the backend run: - -```console -$ bash ./scripts/test.sh -``` - -The tests run with Pytest, modify and add tests to `./backend/app/tests/`. - -If you use GitHub Actions the tests will run automatically. - -### Test running stack - -If your stack is already up and you just want to run the tests, you can use: - -```bash -docker compose exec backend bash scripts/tests-start.sh -``` - -That `/app/scripts/tests-start.sh` script just calls `pytest` after making sure that the rest of the stack is running. If you need to pass extra arguments to `pytest`, you can pass them to that command and they will be forwarded. - -For example, to stop on first error: - -```bash -docker compose exec backend bash scripts/tests-start.sh -x -``` - -### Test Coverage - -When the tests are run, a file `htmlcov/index.html` is generated, you can open it in your browser to see the coverage of the tests. - -## Migrations - -As during local development your app directory is mounted as a volume inside the container, you can also run the migrations with `alembic` commands inside the container and the migration code will be in your app directory (instead of being only inside the container). So you can add it to your git repository. - -Make sure you create a "revision" of your models and that you "upgrade" your database with that revision every time you change them. As this is what will update the tables in your database. Otherwise, your application will have errors. - -* Start an interactive session in the backend container: - -```console -$ docker compose exec backend bash -``` - -* Alembic is configured to import models from their respective modules in the modular architecture - -* After changing a model (for example, adding a column), inside the container, create a revision, e.g.: - -```console -$ alembic revision --autogenerate -m "Add column last_name to User model" -``` - -* For more details on working with Alembic in the modular architecture, see the [Modular Monolith Implementation](./MODULAR_MONOLITH_IMPLEMENTATION.md#alembic-migration-environment) document. - -* Commit to the git repository the files generated in the alembic directory. - -* After creating the revision, run the migration in the database (this is what will actually change the database): - -```console -$ alembic upgrade head -``` - -If you don't want to use migrations at all, uncomment the lines in the file at `./backend/app/core/db.py` that end in: - -```python -SQLModel.metadata.create_all(engine) -``` - -and comment the line in the file `scripts/prestart.sh` that contains: - -```console -$ alembic upgrade head -``` - -If you don't want to start with the default models and want to remove them / modify them, from the beginning, without having any previous revision, you can remove the revision files (`.py` Python files) under `./backend/app/alembic/versions/`. And then create a first migration as described above. - -## Event System - -The project includes an event system for communication between modules. This allows for loose coupling while maintaining clear communication paths. - -### Publishing Events - -To publish an event from a module: - -1. Define an event class in the module's `domain/events.py` file: - -```python -from app.core.events import EventBase - -class MyEvent(EventBase): - event_type: str = "my.event" - # Add event properties here - - def publish(self) -> None: - from app.core.events import publish_event - publish_event(self) -``` - -2. Publish the event from a service: - -```python -event = MyEvent(property1="value1", property2="value2") -event.publish() -``` - -### Subscribing to Events - -To subscribe to events: - -1. Create an event handler in a module's services directory: - -```python -from app.core.events import event_handler -from other_module.domain.events import OtherEvent - -@event_handler("other.event") -def handle_other_event(event: OtherEvent) -> None: - # Handle the event - pass -``` - -2. Import the handler in the module's `__init__.py` to register it. - -For more details, see the [Event System Documentation](./MODULAR_MONOLITH_IMPLEMENTATION.md#event-system-implementation). - -## Email Templates - -The email templates are in `./backend/app/email-templates/`. Here, there are two directories: `build` and `src`. The `src` directory contains the source files that are used to build the final email templates. The `build` directory contains the final email templates that are used by the application. - -Before continuing, ensure you have the [MJML extension](https://marketplace.visualstudio.com/items?itemName=attilabuti.vscode-mjml) installed in your VS Code. - -Once you have the MJML extension installed, you can create a new email template in the `src` directory. After creating the new email template and with the `.mjml` file open in your editor, open the command palette with `Ctrl+Shift+P` and search for `MJML: Export to HTML`. This will convert the `.mjml` file to a `.html` file and now you can save it in the build directory. - -================ -File: backend/TEST_PLAN.md -================ -# Test Plan - -This document outlines the test plan for the modular monolith architecture. - -## Test Types - -### 1.

While the backend waits for the database to be ready and configures everything. You can check the logs to monitor it. - -To check the logs, run (in another terminal): - -```bash -docker compose logs -``` - -To check the logs of a specific service, add the name of the service, e.g.: - -```bash -docker compose logs backend -``` - -## Local Development - -The Docker Compose files are configured so that each of the services is available in a different port in `localhost`. - -For the backend and frontend, they use the same port that would be used by their local development server, so, the backend is at `http://localhost:8000` and the frontend at `http://localhost:5173`. - -This way, you could turn off a Docker Compose service and start its local development service, and everything would keep working, because it all uses the same ports. - -For example, you can stop that `frontend` service in the Docker Compose, in another terminal, run: - -```bash -docker compose stop frontend -``` - -And then start the local frontend development server: - -```bash -cd frontend -npm run dev -``` - -Or you could stop the `backend` Docker Compose service: - -```bash -docker compose stop backend -``` - -And then you can run the local development server for the backend: - -```bash -cd backend -fastapi dev app/main.py -``` - -## Docker Compose in `localhost.tiangolo.com` - -When you start the Docker Compose stack, it uses `localhost` by default, with different ports for each service (backend, frontend, adminer, etc). - -When you deploy it to production (or staging), it will deploy each service in a different subdomain, like `api.example.com` for the backend and `dashboard.example.com` for the frontend. - -In the guide about [deployment](deployment.md) you can read about Traefik, the configured proxy. That's the component in charge of transmitting traffic to each service based on the subdomain. - -If you want to test that it's all working locally, you can edit the local `.env` file, and change: - -```dotenv -DOMAIN=localhost.tiangolo.com -``` - -That will be used by the Docker Compose files to configure the base domain for the services. - -Traefik will use this to transmit traffic at `api.localhost.tiangolo.com` to the backend, and traffic at `dashboard.localhost.tiangolo.com` to the frontend. - -The domain `localhost.tiangolo.com` is a special domain that is configured (with all its subdomains) to point to `127.0.0.1`. This way you can use that for your local development. - -After you update it, run again: - -```bash -docker compose watch -``` - -When deploying, for example in production, the main Traefik is configured outside of the Docker Compose files. For local development, there's an included Traefik in `docker-compose.override.yml`, just to let you test that the domains work as expected, for example with `api.localhost.tiangolo.com` and `dashboard.localhost.tiangolo.com`. - -## Docker Compose files and env vars - -There is a main `docker-compose.yml` file with all the configurations that apply to the whole stack, it is used automatically by `docker compose`. - -And there's also a `docker-compose.override.yml` with overrides for development, for example to mount the source code as a volume. It is used automatically by `docker compose` to apply overrides on top of `docker-compose.yml`. - -These Docker Compose files use the `.env` file containing configurations to be injected as environment variables in the containers. - -They also use some additional configurations taken from environment variables set in the scripts before calling the `docker compose` command. - -After changing variables, make sure you restart the stack: - -```bash -docker compose watch -``` - -## The .env file - -The `.env` file is the one that contains all your configurations, generated keys and passwords, etc. - -Depending on your workflow, you could want to exclude it from Git, for example if your project is public. In that case, you would have to make sure to set up a way for your CI tools to obtain it while building or deploying your project. - -One way to do it could be to add each environment variable to your CI/CD system, and updating the `docker-compose.yml` file to read that specific env var instead of reading the `.env` file. - -## Pre-commits and code linting - -we are using a tool called [pre-commit](https://pre-commit.com/) for code linting and formatting. - -When you install it, it runs right before making a commit in git. This way it ensures that the code is consistent and formatted even before it is committed. - -You can find a file `.pre-commit-config.yaml` with configurations at the root of the project. - -#### Install pre-commit to run automatically - -`pre-commit` is already part of the dependencies of the project, but you could also install it globally if you prefer to, following [the official pre-commit docs](https://pre-commit.com/). - -After having the `pre-commit` tool installed and available, you need to "install" it in the local repository, so that it runs automatically before each commit. - -Using `uv`, you could do it with: - -```bash -❯ uv run pre-commit install -pre-commit installed at .git/hooks/pre-commit -``` - -Now whenever you try to commit, e.g. with: - -```bash -git commit -``` - -...pre-commit will run and check and format the code you are about to commit, and will ask you to add that code (stage it) with git again before committing. - -Then you can `git add` the modified/fixed files again and now you can commit. - -#### Running pre-commit hooks manually - -you can also run `pre-commit` manually on all the files, you can do it using `uv` with: - -```bash -❯ uv run pre-commit run --all-files -check for added large files..............................................Passed -check toml...............................................................Passed -check yaml...............................................................Passed -ruff.....................................................................Passed -ruff-format..............................................................Passed -eslint...................................................................Passed -prettier.................................................................Passed -``` -

Check if a server is already running, or start one if needed -2. Run the basic infrastructure tests first -3. If they pass, run the full test suite -4. Generate test reports -5. Stop the server if it was started by the script - -## Test Categories - -- **Basic Tests**: Verify server is running and basic API functionality works -- **API Contract Tests**: Verify API endpoints adhere to their contracts -- **User Lifecycle Tests**: Verify complete user flows from creation to deletion -- **Authorization Tests**: Verify permission rules are enforced correctly - -## Client Utilities - -The `client_utils.py` module provides a `BlackboxClient` class that wraps httpx with API-specific helpers. This simplifies test writing and maintenance. - -Example usage: - -```python -# Create a client -client = BlackboxClient() - -# Create a user -signup_response, credentials = client.sign_up( - email="test@example.com", - password="testpassword123", - full_name="Test User" -) - -# Login to get a token -client.login(credentials["email"], credentials["password"]) - -# The token is automatically stored and used in subsequent requests -user_profile = client.get("/api/v1/users/me") - -# Create an item -item = client.create_item("Test Item", "Description").json() -``` - -## Test Utilities - -The `test_utils.py` module provides helper functions for common test operations and assertions: - -- `create_random_user`: Create a user with random data -- `create_test_item`: Create a test item for a user -- `assert_validation_error`: Verify a 422 validation error response -- `assert_not_found_error`: Verify a 404 not found error response -- `assert_unauthorized_error`: Verify a 401/403 unauthorized error response -- `verify_user_object`: Verify a user object has the expected structure -- `verify_item_object`: Verify an item object has the expected structure - -## Environment Variables - -The tests use the following environment variables: - -- `TEST_SERVER_URL`: URL of the API server (default: http://localhost:8000) -- `TEST_REQUEST_TIMEOUT`: Request timeout in seconds (default: 30.0) -- `FIRST_SUPERUSER`: Email of the superuser account for admin tests -- `FIRST_SUPERUSER_PASSWORD`: Password of the superuser account - -## Admin Tests - -Some tests require a superuser account to run. These tests will be skipped if: - -1. No superuser credentials are provided in environment variables -2.

Starts a FastAPI server if one is not already running -2. Runs the tests against the running server -3. Generates test reports -4. Stops the server if it was started by the script - -### Client Utilities - -The BlackboxClient provides an interface for interacting with the API: - -```python -# Create a client -client = BlackboxClient() - -# Create a user -signup_response, user_data = client.sign_up( - email="test@example.com", - password="testpassword123", - full_name="Test User" -) - -# Login to get a token -login_response = client.login("test@example.com", "testpassword123") - -# The token is automatically stored and used in subsequent requests -user_profile = client.get("/api/v1/users/me") - -# Create an item -item_response = client.create_item("Test Item", "Test Description") -item_id = item_response.json()["id"] - -# Update an item -update_response = client.put(f"/api/v1/items/{item_id}", json_data={ - "title": "Updated Item" -}) - -# Delete an item -client.delete(f"/api/v1/items/{item_id}") -``` - -## Test Categories - -### API Contract Tests - -Verify that API endpoints adhere to their expected contracts: -- Response schemas -- Status codes -- Validation rules - -```python -def test_user_signup_contract(client): - # Test user signup returns the expected response structure - response, _ = client.sign_up( - email=f"test-{uuid.uuid4()}@example.com", - password="testpassword123", - full_name="Test User" - ) - - result = response.json() - verify_user_object(result) # Check schema fields exist - - # Verify validation errors - invalid_response, _ = client.sign_up(email="not-an-email", password="testpassword123") - assert_validation_error(invalid_response) -``` - -### User Lifecycle Tests - -Verify complete end-to-end user flows: - -```python -def test_complete_user_lifecycle(client): - # Create a user - signup_response, credentials = client.sign_up() - - # Login - client.login(credentials["email"], credentials["password"]) - - # Create an item - item_response = client.create_item("Test Item") - item_id = item_response.json()["id"] - - # Update the item - client.put(f"/api/v1/items/{item_id}", json_data={"title": "Updated Item"}) - - # Delete the item - client.delete(f"/api/v1/items/{item_id}") - - # Delete the user - client.delete("/api/v1/users/me") - - # Verify user is deleted by trying to login again - new_client = BlackboxClient() - login_response = new_client.login(credentials["email"], credentials["password"]) - assert login_response.status_code != 200 -``` - -### Authorization Tests - -Verify that authorization rules are enforced: - -```python -def test_resource_ownership_protection(client): - # Create two users - user1_client = BlackboxClient() - user1_client.create_and_login_user() - - user2_client = BlackboxClient() - user2_client.create_and_login_user() - - # User1 creates an item - item_response = user1_client.create_item("User1 Item") - item_id = item_response.json()["id"] - - # User2 attempts to access User1's item - user2_get_response = user2_client.get(f"/api/v1/items/{item_id}") - assert user2_get_response.status_code == 404, "User2 should not see User1's item" -``` - -## Test Execution Plan - -### Pre-Refactoring Phase - -1. Run the complete test suite against the current architecture -2. Establish a baseline of expected responses and behaviors -3. Create a test report documenting the current behavior - -### During Refactoring Phase - -1. After each module refactoring, run the relevant subset of tests -2. Verify that the refactored module maintains the same external behavior -3. Document any differences or issues encountered - -### Post-Refactoring Phase - -1. Run the complete test suite against the fully refactored architecture -2. Compare results with the pre-refactoring baseline -3. Verify all tests pass with the same results as before refactoring -4. Create a final test report documenting the comparison - -## Dependencies and Setup - -The tests require the following: - -1. httpx: `pip install httpx` -2. pytest: `pip install pytest` -3. A running FastAPI server (started automatically by the test script if not running) -4. The superuser credentials in environment variables (for admin tests) - -## Continuous Integration Integration - -Add the blackbox tests to the CI/CD pipeline to ensure they run on every pull request: - -```yaml -# .github/workflows/backend-tests.yml (example) -name: Backend Tests - -jobs: - blackbox-tests: - runs-on: ubuntu-latest - - services: - postgres: - image: postgres:13 - env: - POSTGRES_USER: postgres - POSTGRES_PASSWORD: postgres - POSTGRES_DB: app_test - ports: - - 5432:5432 - options: >- - --health-cmd pg_isready - --health-interval 10s - --health-timeout 5s - --health-retries 5 - - steps: - - uses: actions/checkout@v3 - - - name: Set up Python - uses: actions/setup-python@v4 - with: - python-version: '3.10' - - - name: Install dependencies - run: | - python -m pip install --upgrade pip - cd backend - pip install -e . - pip install pytest pytest-html httpx - - - name: Run blackbox tests - run: | - cd backend - bash scripts/run_blackbox_tests.sh - - - name: Upload test results - uses: actions/upload-artifact@v3 - with: - name: test-reports - path: backend/test-reports/ -``` - -## Conclusion - -This blackbox testing strategy ensures that the external behavior of the API remains consistent throughout the refactoring process. By focusing exclusively on HTTP interactions without any knowledge of implementation details, these tests provide the most reliable validation that the refactoring does not introduce changes in behavior from an external client's perspective. -

-✨ It just works. ✨ - -### How to Use a Private Repository - -If you want to have a private repository, GitHub won't allow you to simply fork it as it doesn't allow changing the visibility of forks. - -But you can do the following: - -- Create a new GitHub repo, for example `my-full-stack`. -- Clone this repository manually, set the name with the name of the project you want to use, for example `my-full-stack`: - -```bash -git clone git@github.com:fastapi/full-stack-fastapi-template.git my-full-stack -``` - -- Enter into the new directory: - -```bash -cd my-full-stack -``` - -- Set the new origin to your new repository, copy it from the GitHub interface, for example: - -```bash -git remote set-url origin git@github.com:octocat/my-full-stack.git -``` - -- Add this repo as another "remote" to allow you to get updates later: - -```bash -git remote add upstream git@github.com:fastapi/full-stack-fastapi-template.git -``` - -- Push the code to your new repository: - -```bash -git push -u origin master -``` - -### Update From the Original Template - -After cloning the repository, and after doing changes, you might want to get the latest changes from this original template. - -- Make sure you added the original repository as a remote, you can check it with: - -```bash -git remote -v - -origin git@github.com:octocat/my-full-stack.git (fetch) -origin git@github.com:octocat/my-full-stack.git (push) -upstream git@github.com:fastapi/full-stack-fastapi-template.git (fetch) -upstream git@github.com:fastapi/full-stack-fastapi-template.git (push) -``` - -- Pull the latest changes without merging: - -```bash -git pull --no-commit upstream master -``` - -This will download the latest changes from this template without committing them, that way you can check everything is right before committing. - -- If there are conflicts, solve them in your editor. - -- Once you are done, commit the changes: - -```bash -git merge --continue -``` - -### Configure - -You can then update configs in the `.env` files to customize your configurations. - -Before deploying it, make sure you change at least the values for: - -- `SECRET_KEY` -- `FIRST_SUPERUSER_PASSWORD` -- `POSTGRES_PASSWORD` - -You can (and should) pass these as environment variables from secrets. - -Read the [deployment.md](./deployment.md) docs for more details. - -### Generate Secret Keys - -Some environment variables in the `.env` file have a default value of `changethis`. - -You have to change them with a secret key, to generate secret keys you can run the following command: - -```bash -python -c "import secrets; print(secrets.token_urlsafe(32))" -``` - -Copy the content and use that as password / secret key. And run that again to generate another secure key. - - -## Backend Development - -Backend docs: [backend/README.md](./backend/README.md). - -## Frontend Development - -Frontend docs: [frontend/README.md](./frontend/README.md). - -## Deployment - -Deployment docs: [deployment.md](./deployment.md). - -## Development - -General development docs: [development.md](./development.md). - -This includes using Docker Compose, custom local domains, `.env` configurations, etc. - -## Release Notes - -Check the file [release-notes.md](./release-notes.md). - -## License - -The Full Stack FastAPI Template is licensed under the terms of the MIT license. - -================ -File: backend/app/alembic/env.py -================ -""" -Alembic environment configuration. - -This module configures the Alembic environment for database migrations. -""" -import os -from logging.config import fileConfig - -from alembic import context -from sqlalchemy import engine_from_config, pool -from sqlmodel import SQLModel - -# Alembic Config object -config = context.config - -# Interpret the config file for Python logging -fileConfig(config.config_file_name) - -# Import models from all modules for Alembic to detect schema changes -from app.core.config import settings # noqa: E402 -from app.core.logging import get_logger # noqa: E402 - -# Import all models -# Import table models from their respective modules -from app.modules.items.domain.models import Item # noqa: F401 -from app.modules.users.domain.models import User # noqa: F401 - -# Import models from modules -# These imports are for non-table models that have been migrated to modules -# They don't create duplicate table definitions since they don't use table=True - -# Auth module models (non-table models only) -from app.modules.auth.domain.models import ( # noqa: F401 - LoginRequest, - NewPassword, - PasswordReset, - RefreshToken, - Token, - TokenPayload, -) - -# Users module models (non-table models only, not the User table model) -from app.modules.users.domain.models import ( # noqa: F401 - UpdatePassword, - UserCreate, - UserPublic, - UserRegister, - UserUpdate, - UserUpdateMe, - UsersPublic, -) - -# Items module models (non-table models only, not the Item table model) -from app.modules.items.domain.models import ( # noqa: F401 - ItemCreate, - ItemPublic, - ItemsPublic, - ItemUpdate, -) - -# Email module models -from app.modules.email.domain.models import * # noqa: F403, F401 - -# Shared models -from app.shared.models import Message # noqa: F401 - -# Set up target metadata -target_metadata = SQLModel.metadata - -# Initialize logger -logger = get_logger("alembic") - - -def get_url() -> str: - """ - Get database URL from settings. - - Returns: - Database URL string - """ - return str(settings.SQLALCHEMY_DATABASE_URI) - - -def run_migrations_offline() -> None: - """ - Run migrations in 'offline' mode. - - This configures the context with just a URL and not an Engine, - though an Engine is acceptable here as well.

SQLModel Table Duplication - -**Challenge:** SQLModel doesn't allow duplicate table definitions with the same name in the SQLAlchemy metadata, which required careful planning during the implementation of the modular architecture. - -**Solution:** -- Define table models in their respective domain modules -- Ensure consistent table naming across the application -- Use a centralized Alembic configuration that imports all models - -Example: -```python -# app/modules/users/domain/models.py -class User(UserBase, BaseModel, table=True): - """Database model for a user.""" - __tablename__ = "user" - - id: uuid.UUID = Field(default_factory=uuid.uuid4, primary_key=True) -``` - -### 2. Circular Dependencies - -**Challenge:** Module interdependencies led to circular imports, causing import errors during application startup. - -**Solution:** -- Use local imports (inside functions) instead of module-level imports for cross-module references -- Adopt a clear initialization order for modules -- Implement a modular dependency injection system - -Example: -```python -def init_users_module(app: FastAPI) -> None: - # Import here to avoid circular imports - from app.modules.users.api.routes import router as users_router - - # Include the users router in the application - app.include_router(users_router, prefix=settings.API_V1_STR) -``` - -### 3. FastAPI Dependency Injection Issues - -**Challenge:** Encountered errors with FastAPI's dependency injection system when using annotated types and default values together. - -**Solution:** -- Use consistent parameter ordering in route functions: - 1. Security dependencies (e.g., `current_user`) first - 2. Path and query parameters - 3. Request body parameters - 4. Service/dependency injections with default values - -Example: -```python -@router.get("/items/", response_model=ItemsPublic) -def read_items( - current_user: CurrentUser, # Security dependency first - skip: int = 0, # Query parameters - limit: int = 100, - item_service: ItemService = Depends(get_item_service), # Service dependency last -) -> Any: - # Function implementation -``` - -### 4. Alembic Migration Environment - -**Challenge:** Alembic needed to recognize models from all modules in the modular structure. - -**Solution:** -- Configure Alembic's `env.py` to import models from all modules -- Create a systematic approach for model discovery -- Document the process for adding new models to the migration environment - -## Module Structure Implementation - -Each domain module follows this layered architecture: - -``` -app/modules/{module_name}/ -├── __init__.py # Module initialization and router export -├── api/ # API routes and controllers -│ ├── __init__.py -│ └── routes.py -├── dependencies.py # FastAPI dependencies for injection -├── domain/ # Domain models and business rules -│ ├── __init__.py -│ └── models.py -├── repository/ # Data access layer -│ ├── __init__.py -│ └── {module}_repo.py -└── services/ # Business logic - ├── __init__.py - └── {module}_service.py -``` - -## Module Initialization Flow - -The initialization flow for modules has been implemented as follows: - -1. Main application creates a FastAPI instance -2. `app/api/main.py` initializes API routes from all modules -3. Each module has an initialization function (e.g., `init_users_module`) -4. Module initialization registers routes, sets up event handlers, and performs startup tasks - -Example: -```python -def init_api_routes(app: FastAPI) -> None: - # Include the API router - app.include_router(api_router, prefix=settings.API_V1_STR) - - # Initialize all modules - init_auth_module(app) - init_users_module(app) - init_items_module(app) - init_email_module(app) - - logger.info("API routes initialized") -``` - -## Shared Components - -Common functionality is implemented in the `app/shared` directory: - -1. **Base Models** (`app/shared/models.py`) - - Standardized timestamp and UUID handling - - Common model attributes and behaviors - -2. **Exceptions** (`app/shared/exceptions.py`) - - Domain-specific exception types - - Standardized error responses - -## Cross-Cutting Concerns - -1. **Event System** (`app/core/events.py`) - - Pub/sub pattern for communication between modules - - Event handlers and subscribers - - Domain events for cross-module communication - -2. **Logging** (`app/core/logging.py`) - - Centralized logging configuration - - Module-specific loggers - -3. **Database Access** (`app/core/db.py`) - - Base repository implementation - - Session management - - Transaction handling - -## Best Practices Identified - -1. **Consistent Dependency Injection** - - Use FastAPI's Depends for all dependencies - - Order dependencies consistently in route functions - - Use typed dependencies with Annotated when possible - -2. **Module Isolation** - - Keep domains separate and cohesive - - Use interfaces for cross-module communication - - Minimize direct dependencies between modules - -3. **Error Handling** - - Use domain-specific exceptions - - Convert exceptions to HTTP responses at the API layer - - Provide clear error messages and appropriate status codes - -4. **Documentation** - - Document transitional patterns clearly - - Add comments explaining architecture decisions - - Provide usage examples for module components - -## Event System Implementation - -The event system is a critical component of the modular monolith architecture, enabling loose coupling between modules while maintaining clear communication paths. It follows a publish-subscribe (pub/sub) pattern where events are published by one module and can be handled by any number of subscribers in other modules. - -### Core Components - -1. **EventBase Class** (`app/core/events.py`) - - Base class for all events in the system - - Provides common structure and behavior for events - - Includes event_type field to identify event types - -2. **Event Publishing** - - `publish_event()` function for broadcasting events - - Handles both synchronous and asynchronous event handlers - - Provides error isolation (errors in one handler don't affect others) - -3. **Event Subscription** - - `subscribe_to_event()` function for registering handlers - - `@event_handler` decorator for easy handler registration - - Support for multiple handlers per event type - -### Domain Events - -Domain events represent significant occurrences within a specific domain. They are implemented as Pydantic models extending the EventBase class: - -```python -# app/modules/users/domain/events.py -from app.core.events import EventBase, publish_event - -class UserCreatedEvent(EventBase): - """Event emitted when a new user is created.""" - event_type: str = "user.created" - user_id: uuid.UUID - email: str - full_name: Optional[str] = None - - def publish(self) -> None: - """Publish this event to all registered handlers.""" - publish_event(self) -``` - -### Event Handlers - -Event handlers are functions that respond to specific event types. They can be defined in any module: - -```python -# app/modules/email/services/email_event_handlers.py -from app.core.events import event_handler -from app.modules.users.domain.events import UserCreatedEvent - -@event_handler("user.created") -def handle_user_created_event(event: UserCreatedEvent) -> None: - """Handle user created event by sending welcome email.""" - email_service = get_email_service() - email_service.send_new_account_email( - email_to=event.email, - username=event.email, - password="**********" # Password is masked in welcome email - ) -``` - -### Module Integration - -Each module can both publish events and subscribe to events from other modules: - -1. **Publishing Events** - - Domain services publish events after completing operations - - Events include relevant data but avoid exposing internal implementation details - -2. **Subscribing to Events** - - Modules import event handlers at initialization - - Event handlers are registered automatically via the `@event_handler` decorator - - No direct dependencies between publishing and subscribing modules - -### Best Practices - -1. **Event Naming** - - Use past tense verbs (e.g., "user.created" not "user.create") - - Follow domain.event_name pattern (e.g., "user.created", "item.updated") - - Be specific about what happened - -2. **Event Content** - - Include only necessary data in events - - Use IDs rather than full objects when possible - - Ensure events are serializable - -3. **Handler Implementation** - - Keep handlers focused on a single responsibility - - Handle errors gracefully within handlers - - Consider performance implications for synchronous handlers - -### Example: User Registration Flow - -1. User service creates a new user in the database -2. User service publishes a `UserCreatedEvent` -3. Email module's handler receives the event -4. Email handler sends a welcome email to the new user -5. Other modules could also handle the same event for different purposes - -This approach decouples the user creation process from sending welcome emails, allowing each module to focus on its core responsibilities. - -## Future Work - -1. **Performance Optimization** - - Identify and optimize performance bottlenecks - - Implement caching strategies for frequently accessed data - - Optimize database queries and ORM usage - -2. **Enhanced Event System** - - Add support for asynchronous event processing - - Implement event persistence for reliability - - Create more comprehensive event monitoring and debugging tools - -3. **Module Configuration** - - Implement module-specific configuration settings - - Create a more flexible configuration system - - Support environment-specific module configurations - -4. **Testing Improvements** - - Expand test coverage for all modules - - Implement more comprehensive integration tests - - Add performance benchmarking tests - - Create unit tests for domain services and repositories - - Develop integration tests for module boundaries - - Implement end-to-end tests for complete flows - -## Conclusion - -The modular monolith architecture has been successfully implemented. The new architecture significantly improves code organization, maintainability, and testability while maintaining the deployment simplicity of a monolith. - -The implementation addressed several challenges, particularly with SQLModel table definitions, circular dependencies, and FastAPI's dependency injection system.
