FastAPI Assignment – Initial Architecture Setup

Started building the FastAPI assignment: project structure, routing, and foundational backend logic.

public

What I did

  • Initialized the FastAPI project structure.
  • Configured virtual environment and dependencies.
  • Implemented initial API routes.
  • Set up basic CRUD logic structure for future expansion.
  • Organized files to keep routing, models, and logic separated.

What I learned

  • FastAPI’s structure encourages clean separation between routing and business logic.
  • Type hints significantly improve readability and maintainability.
  • Planning folder structure early prevents refactoring chaos later.

Problems

  • Understanding how to properly structure route files without mixing logic.
  • Balancing simplicity with future scalability.
  • Debugging environment and dependency issues.

Resources

Next steps

  • Complete remaining CRUD operations.
  • Improve validation and error handling.
  • Refactor routes if needed for cleaner architecture.
