About SOCKJS

An open-source WebSocket emulation library for real-time communication.

Our Mission

SOCKJS aims to make real-time web communication accessible to everyone. We provide a robust, cross-browser solution that automatically falls back to alternative transports when WebSockets are not available, ensuring your applications work everywhere.
