Overview

WebSockets enable real-time, bidirectional communication between a client (usually a browser) and a server. Unlike HTTP, which is request-response based, WebSockets keep a connection open, allowing both parties to send data at any time.

Key Features

  • Full-Duplex: Simultaneous two-way communication.
  • Low Latency: Eliminates the overhead of repeated HTTP handshakes.
  • Persistent Connection: The connection stays open until explicitly closed.
  • Binary Support: Can transmit both text and binary data.

Use Cases

  • Chat applications.
  • Real-time financial tickers.
  • Multiplayer games.
  • Collaborative editing tools.
