Can Beego be used for real-time Web applications?

Yes, Beego can be used for real-time web applications. Although it is primarily designed for traditional web applications and APIs, it also supports WebSockets, which enable real-time communication between clients and servers.

How Beego Supports Real-Time Features

1️⃣ WebSocket Integration: Beego has built-in support for WebSockets, allowing bi-directional communication.
2️⃣ Goroutines for Concurrency: Since Beego is built on Go, it leverages goroutines to handle thousands of simultaneous connections efficiently.
3️⃣ Pub/Sub Messaging: Beego can integrate with Redis Pub/Sub or Kafka for real-time event streaming.

Example of WebSocket in Beego

func (c *WebSocketController) Join() {
ws, err := websocket.Upgrade(c.Ctx.ResponseWriter, c.Ctx.Request, nil, 1024, 1024)
if err != nil {
http.Error(c.Ctx.ResponseWriter, "Could not open WebSocket", http.StatusBadRequest)
return
}
defer ws.Close()

for {
_, message, err := ws.ReadMessage()
if err != nil {
break
}
fmt.Println("Received:", string(message))
}
}

This can be used for:

• Chat applications

• Live notifications

• Real-time dashboards

Conclusion

Beego is not primarily a real-time framework, but it supports WebSockets, making it a great choice for applications needing real-time updates.
