This is out of scope, at least for now.
You can use any js libraries with ct.js, though, so I would recommend searching to existing solutions and including it to your ct projects. For example, this is a browser-side library by socket.io. After getting the library you create a folder called `include` in your project's folder (like `ctjs/projects/fancyGame/includes/`) and put the library here. After this, put a <script> tag to your game code with a module called `akatemplate`.
Another way to include a library is to paste it to the Scripts section at the Settings tab.
