Overview
WebSocket support is available from Bruno 2.13.0.
Bruno now supports WebSocket connections, enabling you to test real-time communication protocols and bidirectional data exchange. This feature allows you to establish WebSocket connections, send messages, and receive responses in real-time.
What are WebSockets?
WebSockets provide a persistent, full-duplex communication channel between a client and server. Unlike traditional HTTP requests that follow a request-response pattern, WebSockets maintain an open connection that allows both the client and server to send messages at any time.
WebSocket vs HTTP
| Feature | HTTP | WebSocket |
|---|---|---|
| Connection | Request-Response | Persistent |
| Latency | Higher (connection overhead) | Lower (persistent connection) |
| Data Flow | Unidirectional | Bidirectional |
| Use Case | Traditional APIs | Real-time applications |
| Overhead | Higher per request | Lower per message |
| Complexity | Simple | More complex |
