In this article, we discussed the features of WebSockets, its applications in Rust, and how to use it with the actix-web package. We demonstrated how to create an efficient, real-time chat application, using React and Next.js to establish WebSocket connections to the Actix Web server. The code from this article is available on GitHub.
There are many packages we can use to write a WebSocket server in Rust. For this tutorial, we’ll use Actix Web; it is a mature package and is easy to use.
