Directory Breakdown

cmd/server/

The cmd directory hosts the main entry point for the application. The server/main.go file initializes and starts the HTTP server.

internal/

This directory contains core application logic that is not intended to be exposed outside of this project.

• gen/: We are using oapi-codegen to generate code from the ./spec/openapi.yaml file.
• handlers/: Defines HTTP route handlers that process incoming requests and return responses.
• services/: Implements the business logic and acts as an intermediary between handlers and the data layer.
• server/: Implements the HTTP server code to offload the main entry point.
• middleware/: Contains reusable middleware functions for processing HTTP requests, such as logging or authentication.
• config/: Manages application configurations, such as environment variables and settings.

pkg/

The pkg directory includes reusable utilities and libraries that can be used across the project.

• logger/: Utilities for structured logging.
• response/: Helper functions for building consistent HTTP responses.

test/

Organized directory for tests:

• integration/: Integration tests to verify end-to-end functionality.
• unit/: Unit tests for individual components.

go.mod and go.sum

These files define and manage the project's dependencies using Go modules.

README.md
