I recommend you place it in a dedicated empty directory (I’ll call mine chat-example). Make sure Node.JS is installed.įirst let’s create a package.json manifest file that describes our project.

We’re going to use the Node.JS web framework express to this end. The first goal is to set up a simple HTML webpage that serves out a form and a list of messages. Whenever you write a chat message, the idea is that the server will get it and push it to all other connected clients. This means that the server can push messages to clients. Sockets have traditionally been the solution around which most real-time chat systems are architected, providing a bi-directional communication channel between a client and a server. It involves polling the server for changes, keeping track of timestamps, and it’s a lot slower than it should be. Writing a chat application with popular web applications stacks like LAMP (PHP) has normally been very hard. const initSocket (instance: socketio.Namespace): socketio.Namespace > e (onAuth). We pass the Socket.io’s server instance to our function in which we set the middlewares. It requires almost no basic prior knowledge of Node.JS or Socket.IO, so it’s ideal for users of all knowledge levels. We create an Express app, HTTP server and init sockets. It requires almost no basic prior knowledge of Node.JS or Socket.IO, so its ideal for users of all. Var sharedsession = require('express-socket.io-session') Ĭonsole.log('express session ID:', ) Ĭonsole.log('socket session ID:', ) Ĭonsole.In this guide we’ll create a basic chat application. In this guide well create a basic chat application. Secure: false, // will change to true when deploying to production nnect().catch(console.error) Ĭonst session = require('express-session') How can I fix this? I need them to be consistent even if user visits first timeĬonst RedisStore = require('connect-redis').default Ĭonst ) When, however, the user reloads or visits later again, then the session IDs are the same. However, when the user visits my app for the first time ever, the console.log of the Express session ID and the Socket io session IDs are different. I'm using 'express-socket.io-session' to share session data between socket.io and express.
