This project is an open-source Erlang implementation of an Engine.IO server. Based on sinnus/socket.io-cowboy and improvements thereto by wuyingfengsui (including adding support for the v1 Socket.IO protocol), this fork modifies its predecessors as follows:

1. Supports only the Engine.IO protocol, not the Socket.IO protocol, although that would be easy to layer on top.
2. Removes support for older Socket.IO protocol.
3. Adds end-to-end tests using the reference implementation of the Engine.IO JavaScript client.
