![]() ![]() WebSocket communication takes place over a single TCP socket using either WS (port 80) or WSS (port 443) protocol. Once the server accepts the handshake request sent by the client and initiates a WebSocket connection, they can send data to each other with less overhead at will. The WebSocket protocol has only two agendas: To open up a handshake and to help the data transfer. The WebSocket protocol offers persistent, real-time, full-duplex communication between the client and the server over a single TCP socket connection. ![]() Sending and listening to messages on the Node.js WebSocket server. ![]() Sending and listening to messages on the client side using react-use-websocket.Agenda 2: Real-time message transmission.Creating a handshake request at the client level.Agenda 1: WebSocket establishes a handshake between server and client.How to use WebSockets with Node.js and React.How is WebSocket different from HTTP polling, HTTP streaming, and server-sent events?.In this article, I will explain the theoretical concepts behind the WebSocket protocol and demonstrate how to build a real-time collaborative document editing app with a Node.js backend and React frontend using the WebSocket protocol. The WebSocket protocol solves this drawback of the traditional HTTP pattern, offers a full-duplex (or two-way) communication mechanism, and helps developers build real-time apps. But the HTTP-based RESTful concept uses a simplex communication (one-way), so we can’t send data directly from the client (frontend) to the server (backend) without implementing workarounds such as polling. Nowadays, we typically develop loosely coupled, separate backends and frontends by connecting the two with a network-oriented communication line.įor example, developers often use the RESTful pattern with the HTTP protocol to implement a communication line between the frontend and backend for data transferring. It was previously quite common for most web apps to have a closely connected backend and frontend, so the apps served data with the view content to the user’s browser. For more information on WebSockets and React, read this article on implementing two-way communication in React. We recently updated it to include a sample app that features React v18, employs Hooks and functional components, and uses the react-use-websocket library.
