This library allows you to connect to a STOMP broker over WebSocket. This library supports full STOMP specifications and all current protocol variants. Most popular messaging brokers support STOMP and STOMP over WebSockets either natively or using plugins.

In general JavaScript engines in browsers are not friendly to binary protocols, so using STOMP is a better option because it is a text oriented protocol.

This library was originally developed by Jeff Mesnil.
