Build a REST API with FastAPI (Python)
Build a real REST API with FastAPI - routes, validation, CRUD, and a database - set up and run on your own machine, the way you would at work.
- Setup and Hello, API Create a virtualenv, install FastAPI and Uvicorn, write your first endpoint, and watch the auto-generated docs appear.
- Routes and Pydantic Models Add path and query parameters, define a request body as a Pydantic model, and let FastAPI validate incoming data for you.
- CRUD with an In-Memory Store Wire up create, read, update, and delete endpoints over a plain Python dictionary, then exercise every one of them with curl.
- Validation, Errors, and Status Codes Raise HTTPException for missing notes, return the right status code for each operation, and tighten the input rules with richer validation.
- A Database, then Ship It Swap the in-memory dict for a SQLite database so data survives restarts, then run, test, and learn how you'd deploy the finished API.
