# go-ws
|
|
|
|
WebSocket hub for real-time streaming in Go. Implements the hub pattern with centralised connection management, named channel pub/sub, token-based authentication on upgrade, client-side reconnection with exponential backoff, and a Redis pub/sub bridge for coordinating broadcasts across multiple hub instances. The envelope pattern with a per-bridge source ID prevents loop amplification when the Redis bridge is in use.

## Quick Start
|
|
|
|
```go
|
|
import "forge.lthn.ai/core/go-ws"
|
|
|
|
hub := ws.NewHub()
|
|
go hub.Run(ctx)
|
|
|
|
// Mount on any HTTP mux
|
|
http.HandleFunc("/ws", hub.Handler())
|
|
|
|
// Send process output to subscribers of "process:abc"
|
|
hub.SendProcessOutput("abc", "output line")
|
|
|
|
// Redis bridge for multi-instance coordination
|
|
bridge, _ := ws.NewRedisBridge(hub, ws.RedisConfig{Addr: "localhost:6379"})
|
|
bridge.Start(ctx)
|
|
```
