WebSocket migration (ws → gox/ws)

Use gox/ws for low-level WebSocket servers and clients (similar to the ws package). For Socket.IO-style rooms and fallbacks, use raw WebSockets or a dedicated Go library and document app-specific patterns.

Server

srv := ws.NewServer(nil)
http.Handle("/socket", srv.HandleWS(func(c *ws.Conn) {
    for {
        var msg map[string]any
        if err := c.ReadJSON(&msg); err != nil {
            return
        }
        _ = c.WriteJSON(msg)
    }
}))

With gox/http:

app := http.New()
app.HandleWS("/ws", nil, func(c *http.Ctx, conn *ws.Conn) error {
    // ...
    return nil
})

Client

conn, err := ws.Dial(ctx, "wss://example.com/ws", nil)
defer conn.Close()
_ = conn.Send(map[string]string{"type": "ping"})
