Implement RESTful API for User Management

[loftwah]

We need to create a RESTful API that allows for both reading and writing user data. This API should provide endpoints for creating, reading, updating, and deleting user information, as well as managing related data such as links and achievements. The API should be secure, efficient, and follow REST best practices.

Tasks:

1. Set up API infrastructure:

   • Create a new api namespace in the routes
   • Set up versioning (e.g., v1) for future compatibility
   • Implement API authentication (e.g., using JWT or API keys)

2. Create API controllers:

   • ApiController (base controller for shared functionality)
   • Api::V1::UsersController
   • Api::V1::LinksController
   • Api::V1::AchievementsController

3. Implement CRUD operations for Users:

   • GET /api/v1/users (index)
   • GET /api/v1/users/:id (show)
   • POST /api/v1/users (create)
   • PATCH/PUT /api/v1/users/:id (update)
   • DELETE /api/v1/users/:id (destroy)

4. Implement nested resources for Links and Achievements:

   • GET /api/v1/users/:user_id/links
   • POST /api/v1/users/:user_id/links
   • GET /api/v1/users/:user_id/achievements
   • POST /api/v1/users/:user_id/achievements

5. Implement serializers for API responses:

   • UserSerializer
   • LinkSerializer
   • AchievementSerializer

6. Add pagination for index endpoints

7. Implement filtering and sorting options for index endpoints

8. Add rate limiting to prevent API abuse

9. Implement proper error handling and status codes

10. Create comprehensive API documentation (e.g., using Swagger/OpenAPI)

11. Write tests for all API endpoints:

    • Request specs for each endpoint
    • Edge case testing (e.g., invalid inputs, unauthorized access)

12. Implement caching for frequently accessed data

13. Ensure all API actions respect user permissions and data privacy

14. Add logging for API requests for monitoring and debugging

15. Create a developer portal or section in the app for API key management

Detailed API Endpoints:

Users:

• GET /api/v1/users
• GET /api/v1/users/:id
• POST /api/v1/users
• PATCH /api/v1/users/:id
• DELETE /api/v1/users/:id

Links:

• GET /api/v1/users/:user_id/links
• GET /api/v1/users/:user_id/links/:id
• POST /api/v1/users/:user_id/links
• PATCH /api/v1/users/:user_id/links/:id
• DELETE /api/v1/users/:user_id/links/:id

Achievements:

• GET /api/v1/users/:user_id/achievements
• GET /api/v1/users/:user_id/achievements/:id
• POST /api/v1/users/:user_id/achievements
• PATCH /api/v1/users/:user_id/achievements/:id
• DELETE /api/v1/users/:user_id/achievements/:id

This API will provide a robust interface for managing user data programmatically, enabling integrations and potentially a mobile app in the future.

This should be both read and write. Manage it the best way possible.
