Here is an example server. The tcp argument for net.Listen() can be changed to udp if you want to change protocol:
package mainimport ( "net" "fmt" "log")var protocol = "tcp" // tcp or udpvar listenAddress = "localhost:3000"func main() { listener, err := net.Listen(protocol, listenAddress) if err != nil { log.Fatal("Error creating listener. ", err) } log.Printf("Now listening for connections.") for { conn, err := listener.Accept() if err != nil { log.Println("Error accepting connection. ", err) } go handleConnection(conn) }}func handleConnection(conn net.Conn) { incomingMessageBuffer := make([]byte, 4096) numBytesRead, err := conn.Read(incomingMessageBuffer) if err != nil { log.Print("Error reading from client. ", err)
