SoCKj5...8xYz3qWhat is SOCKJS?
SOCKJS is a transport abstraction layer that provides a WebSocket-like API while supporting multiple fallback transports. When WebSockets are unavailable or blocked, SOCKJS automatically switches to the next best transport—XHR streaming, long polling, or others.
This makes your real-time applications resilient across all networks, proxies, and corporate firewalls without any code changes.
