About

Socket.IO is a library that enables real-time, bidirectional and event-based communication between the browser and the server.

WebSocket is a communication protocol that enables persistent, full-duplex data exchange between a client and a server over a single TCP connection.

It maintains a long-lived connection that allows low-latency message exchange, supports both text and binary frames, minimizes overhead by avoiding repeated request headers, and enables servers to push data to clients in real time.
