Using Socket.IO with React

Connect to a Socket.IO server from React, listen to events, and emit messages from hooks.

Why Socket.IO?

Socket.IO adds rooms, namespaces, automatic reconnection, and event-based messaging on top of WebSockets with a fallback to HTTP long-polling — much more ergonomic than raw WebSocket.

Installing the Client

Install the Socket.IO client package.

npm install socket.io-client
