chore: refactor main.py

[eniiku]

Description

The main.py file currently contains a mix of configuration, exception handling, routing, and initialization logic, making it difficult to maintain, extend, and test.

Introducing this refactoring will make the codebase more maintainable.

---

Proposed Changes

1. Move Uvicorn Port to Environment File

• Update .env.example with PORT variable. Setting a value of 7001 as it's default.
• Update main.py to read the port from the Settings class in api/utils/settings.py.

2. Extract Configuration to a config file (api/utils/config.py):

• Create functions like setup_cors and setup_middleware.
• Update main.py to use these functions.

3. Move Exception Handlers to a Dedicated File

• Create api/utils/exceptions.py with handlers for HTTPException, RequestValidationError, IntegrityError, and generic exceptions.
• Update main.py to use these handlers.

4. Use a Router for Root Endpoints

• Create api/core/routers/root.py with an APIRouter for the root endpoints (/ and /probe).
• Update main.py to include the new router.

---

Acceptance Criteria

• Environment Configuration:

  • The PORT variable is defined in .env.example.
  • The application reads the port from the Settings class in api/utils/settings.py.

• Configuration Modularity:

  • Configuration-related code is moved to api/utils/config.py.
  • The application runs with the new configuration setup.

• Exception Handling:

  • Exception handlers are moved to api/utils/exceptions.py.
  • The application handles exceptions correctly.

• Root Endpoints:

  • Root endpoints are moved to api/core/routers/root.py.
  • The application serves the root endpoints correctly.

---

Testing

• Verify that the application starts using the port specified in .env.
• Test all endpoints to ensure they work as expected.
• Verify that exceptions are handled correctly.
• Check that directories are created correctly.
