ChatJS is a jQuery plugin for instant messaging. It's completely client-side, so it's completely platform agnostic.
Server side communication is implemented through Adapters. The adapter is the piece of code that is responsible for handling client/server communucation. ChatJS comes with a demo adapter that you can see running in the bottom right of this page. It's just an echobot that will repeat what you say. You can use it as a boilerplate to implement your own. The server portion of your solution will be written according to the adapter specification.
I intend to display here a list of all adapter implementations. ASP.NET MVC coming soon.
Once your server code is ready, that's how ChatjS looks in the client:
Pull requests are very welcome.
If you want to implement an adapter, that's very welcome too. Please let me know if you need assistance by submitting a GitHub issue. I have a tight schedule but I'll answer as I have time.
