Crash Course On FastAPI For Web Developers- Level 1 Part1

Learn the basics of fast API by building a movie JSON object, exploring JSON data types, and using fast API for configuration and lightweight data storage.

Understand how http requests and responses flow between client and server by examining request line, method, url, headers, and body, and the status line, headers, and body of responses.

Learn how http methods define actions on a server, including get, post, put, and delete, with examples for retrieving movie data, creating resources, updating by id, and removing items.

Explore how endpoints map url paths to backend functions and support http methods like get, post, put, and delete. Understand base urls, path parameters in curly braces, and query parameters.

Learn how Swagger UI provides an interactive, web-based interface for FastAPI API documentation, enabling you to explore and test endpoints in a browser by visiting /doc.

Explore swagger ui to test fastapi endpoints end-to-end. Practice using try it out, execute requests, and verify get and post endpoints with path parameters and base url.

Build a FastAPI movie API by defining a movie class and implementing crud operations: retrieve all, by id, by genre, by year; create, update, or delete entries; set up environment.

Set up your project folder and virtual environment, then build a FastAPI movies API with endpoints for listing and retrieving by id. Test and explore with Swagger UI.

Pedantics is a Python library for data validation and settings management used with FastAPI to define models that validate data types, enforce constraints, and auto-parse data.

Learn field validation in pedantic by applying field constraints and custom validators with decorators. Explore default and optional fields, Pydantic error reporting, and rules for data types, ranges, lengths, patterns.

Explore adding validators in fastapi by updating a movie model to inherit the base model from pedantic and apply field and custom validators. Test with uvicorn and swagger UI.

Master HTTP status codes from 1xx to 5xx, with examples like 200, 201, 204, 301, 404, and 500, and learn to apply them in fastapi for clear api design.

Use HTTP exceptions in FastAPI to raise HTTPException with a status code, detail, and optional headers, standardizing responses. Handle missing resources, authentication errors, and invalid requests clearly and predictably.
