Developing a Single Page App with FastAPI and React

Abstraction: Step-by-step CRUD app tutorial using FastAPI backend and React frontend

Key points:

• Stack: FastAPI 0.115.7 + Uvicorn (ASGI) backend on port 8000; React 19 + TypeScript scaffolded with Vite on port 5173; Chakra UI for styling
• CORS must be explicitly enabled via FastAPI's CORSMiddleware to allow cross-origin requests from the React frontend
• State management uses React Context API (createContext/useContext) and hooks (useState, useEffect) — no external state library needed for simple CRUD
• Implements all four REST routes: GET /todo, POST /todo, PUT /todo/{id}, DELETE /todo/{id} with async route handlers
• In-memory list used as data store for the tutorial; article suggests wiring up a real database and deploying backend to Heroku, frontend to Netlify
