![]() Accessing cookies in the socket.io middlewareīefore we start building the backend of our live score site, let's first set up our directory and files.In this tutorial, we will cover the following topics: Our live score website will provide an admin panel for the administrators to update the score. Discussing how to build a live score website will help us study socket.io in depth, as it requires socket.io authentication, and optionally, integrating socket.io with Express. We will create a football live score website. A live score website shows score changes in real time to the user as soon as the administrator updates the scores. The best way to master socket.io is by building a real-world application, which is what we will be doing in this tutorial. In our previous article, we made an intro to real-time bidirectional communications between browsers and webSocket servers.

Call listen on the HTTPS server object.Pass both of those things to the expressWs function.Create the HTTPS server, providing the TLS options and the Express app.To summarize the code, the right order of operations ended up being: Key: fs.readFileSync(`$)) Ĭonsole.log("Express HTTP and Websocket server listening on 3000") And, of course, after getting it working, I found an example in the express-ws repository that lays out exactly what I needed to do.īut if anyone else finds themselves working with this same combination of technologies, I hope this post can save them time and searching. But it took several iterations before I got things just right for the specific combination of Express/express-ws/mTLS. And there are dozens of other examples of how to set up a TLS-enabled WebSocket server, using a variety of different libraries. There are hundreds of examples out there of how to set up an Express app with a certificate and key for TLS. The app was using a library called express-ws to handle WebSocket connections. I recently spent some time adding mutual TLS (mTLS) support to a Node.js Express app. ![]()
