FastAPI Learning

This repository documents my progress while learning backend development with FastAPI.

The project started with simple routes and gradually grew into a small API with user CRUD, database persistence, migrations, authentication and tests.

What I’m learning

• HTTP requests, responses and status codes
• REST API structure
• FastAPI routes and dependencies
• Pydantic schemas and validation
• CRUD operations
• SQLAlchemy and database sessions
• Database migrations with Alembic
• Password hashing
• JWT authentication and protected routes
• Error handling
• Testing APIs with pytest
• Test coverage
• Code formatting and linting

How I’m using this repository

This is a learning project, the goal is to make things work while learning

I’m using it to understand how the pieces of a backend connect, how a request reaches a route, how data is validated, how the application communicates with the database, how authentication works, and how can I write some tests.

The code will keep changing as I learn and refactor things.
