Socket.IO – A Fast & Reliable Real-Time Engine


Socket.IO enables real-time bidirectional event-based communication. It works on every platform, browser or device, focusing equally on reliability and speed. You can push data to clients that gets represented as real-time counters, charts or logs.

Starting in 1.0, it’s possible to send any blob back and forth: image, audio, video. And it allows users to concurrently edit a document and see each other’s changes. It’s one of the most powerful JavaScript frameworks on GitHub, and most depended-upon NPM module.
