Asked 4 months ago

I'm building a real-time feature in my React app and considering using WebSockets. What are some effective practices for this? Any help would be appreciated, thanks!

To effectively use WebSockets in a React application, start by choosing a robust WebSocket library like Socket.IO. This library simplifies WebSocket communication and handles reconnects and broadcasting efficiently. In your React components, establish the WebSocket connection in the `componentDidMount` lifecycle method (or `useEffect` hook for functional components).

Ensure to close the WebSocket connection in the `componentWillUnmount` method to prevent memory leaks. Manage the state of WebSocket data using React's state management or libraries like Redux. Also, consider implementing fallbacks for clients where WebSockets are not supported.
