WebSocket
WebSocket is a protocol for full-duplex communication over a single TCP connection. Compared to traditional HTTP requests, WebSocket offers lower latency and higher communication efficiency, making it especially suitable for real-time communication scenarios such as online chat, real-time data push, game synchronization, and more.
Use Cases
| Scenario | Description |
|---|---|
| Instant Messaging / Online Chat | In scenarios like customer service or chat systems, users can send and receive messages in real time without frequent polling to the server. |
| Real-time Push | For system notifications, weather alerts, stock prices, etc., the server can actively push data to clients to ensure timely delivery of information. |
| Live Streaming / Danmaku | During live broadcasts, real-time transmission of comments, likes, and interactions among viewers enhances the interactive experience. |
| Multi-user Collaboration | In applications such as collaborative document editing, online spreadsheets, or whiteboard tools, user operations are synchronized in real time to avoid conflicts. |
