3.1 How to Write an Echo WebSocket Server in Node.js – Fun with WebSockets!

In this video, I explain how to create a WebSocket server in Node.js that performs an echo function, i.e. returns to the client whichever message it received. I also explain how to test if the server works using a simple Chrome extension.

This video is part of the series “Fun with WebSockets! 🌐🔌”, taught by @garciadelcastillo on @ParametricCamp.
