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.
