introduction to colyseus and xterm.js - building a social terminal in javascript and node.js
in this video, we give an introduction to colyseus which is a gaming server popular in the metaverse with platforms such as decentraland.
in this example we show how you can build your own colyseus server with javascript, node.js and websockets.
In particular we build the barebones of a social terminal where every participant can see real-time every keystroke typed in the terminal as well as being able to type their own messages. to implement this we create a terminal using xterm.js a popular web terminal module used by vscode and hyper.
at the end of this video you should understand how game engines such as colyseus will be powerful in the metaverse to manage game or world state, chat or any social experiences and you'll be able to use it for your solutions, as you will have built your own solution.
