How do I use WebSockets for real-time updates?

WebSockets are a powerful tool for enabling real-time updates in web applications. They provide a full-duplex communication channel over a single TCP connection, which allows for instant data exchange between a client and server. This is particularly useful for applications like chat apps, live notifications, and collaborative tools.

Below is a basic example of how to set up a WebSocket server in Go and connect to it from a web client:


        // Go WebSocket server setup
        package main

        import (
            "fmt"
            "net/http"
            "github.com/gorilla/websocket"
        )

        var upgrader = websocket.Upgrader{}

        func handler(w http.ResponseWriter, r *http.Request) {
            conn, err := upgrader.Upgrade(w, r, nil)
            if err != nil {
                fmt.Println("Error during connection upgrade:", err)
                return
            }
            defer conn.Close()

            for {
                msgType, msg, err := conn.ReadMessage()
                if err != nil {
                    fmt.Println("Error reading message:", err)
                    break
                }
                fmt.Println("Received:", string(msg))
                if err := conn.WriteMessage(msgType, msg); err != nil {
                    fmt.Println("Error writing message:", err)
                    break
                }
            }
        }

        func main() {
            http.HandleFunc("/ws", handler)
            http.ListenAndServe(":8080", nil)
        }
