Integrating WebSockets with React and Python Backend

 WebSockets are a powerful tool for building real-time web applications where the server and client can communicate instantly without needing to refresh the page. They enable two-way communication over a single, long-lived connection, which makes them ideal for real-time features such as chat apps, live notifications, and live updates in dashboards. In this blog, we will walk through integrating WebSockets between a React frontend and a Python backend using FastAPI for the backend and Socket.IO for the frontend in React. 1. Setting Up the Python Backend with WebSockets For the backend, we will use FastAPI . FastAPI is an easy-to-use, modern framework for building APIs and supports WebSocket integration out-of-the-box. Socket Initialization : The useEffect hook establishes a connection with the WebSocket server at http://localhost:8000 . Sending and Receiving Messages : We listen for incoming messages from the server with socket.on("message") and display them in t...
