SockJS is a browser JavaScript library that provides a WebSocket-like object. SockJS gives you a coherent, cross-browser, Javascript API which creates a low latency, full duplex, cross-domain communication channel between the browser and the web server.

Under the hood SockJS tries to use native WebSockets first. If that fails it can use a variety of browser-specific transport protocols and presents them through WebSocket-like abstractions.

SockJS-client is intended to work for all modern browsers and in environments which don't support WebSocket protocol, for example behind restrictive corporate proxies. [ https://github.com/sockjs/sockjs-client ]

SockJS-node is a Node.js server side counterpart of SockJS-client browser library written in CoffeeScript. [ https://github.com/sockjs/sockjs-node ]
