Contributing ⇧

activist uses Matrix for internal communication. You're more than welcome to join us in our public chat rooms to share ideas, ask questions or just say hi to the team :) We'd suggest that you use the Element client and Element X for a mobile app.

Please see the contribution guidelines if you are interested in contributing. Work that is in progress or could be implemented is tracked in the issues and projects.

Note

Just because an issue is assigned on GitHub doesn't mean the team isn't open to your contribution! Feel free to write in the issues and we can potentially reassign it to you.

Also check the -next release- and -priority- labels in the issues for those that are most important, as well as those marked good first issue that are tailored for first-time contributors. For those new to coding or our tech stack, we've collected links to helpful documentation pages in the contribution guidelines.

We would be happy to discuss granting you further rights as a contributor after your first pull requests, with a maintainer role then being possible after continued interest in the project. activist seeks to be an inclusive, diverse and supportive organization. We'd love to have you on the team!

Environment setup ⇧

1. First and foremost, please see the suggested IDE setup in the dropdown below to make sure that your editor is ready for development.

Important

Suggested IDE setup

VS Code

Install the following extensions:

• charliermarsh.ruff
• streetsidesoftware.code-spell-checker

2. Fork the ts-backend-check repo, clone your fork, and configure the remotes:

Note

Consider using SSH

Alternatively to using HTTPS as in the instructions below, consider SSH to interact with GitHub from the terminal. SSH allows you to connect without a user-pass authentication flow.

To run git commands with SSH, remember then to substitute the HTTPS URL, https://github.com/..., with the SSH one, [email protected]:....

• e.g. Cloning now becomes git clone [email protected]:<your-username>/ts-backend-check.git

GitHub also has their documentation on how to Generate a new SSH key 🔑

# Clone your fork of the repo into the current directory.
git clone https://github.com/<your-username>/ts-backend-check.git
# Navigate to the newly cloned directory.
cd ts-backend-check
# Assign the original repo to a remote called "upstream".
git remote add upstream https://github.com/activist-org/ts-backend-check.git

• Now, if you run git remote -v you should see two remote repositories named:
  • origin (forked repository)
  • upstream (ts-backend-check repository)

3. Create a virtual environment, activate it and install dependencies:

   # Unix or MacOS:
   python3 -m venv venv
   source venv/bin/activate
   
   # Windows:
   python -m venv venv
   venv\Scripts\activate.bat
   
   # After activating venv:
   pip install --upgrade pip
   pip install -r requirements-dev.txt
   
   # To install the CLI for local development:
   pip install -e .

You're now ready to work on ts-backend-check!

Note

Feel free to contact the team in the Development room on Matrix if you're having problems getting your environment setup!
