Broadcasting lan WebSocket Integrasi ing Node.js

Data siaran lan nggabungake WebSocket minangka rong aspek penting kanggo mbangun aplikasi wektu nyata kanthi Node.js. Ing artikel iki, kita bakal njelajah cara nyebarake data lan nggabungake WebSocket kanggo nggawe pengalaman pangguna sing interaktif lan responsif.

Langkah 1: Broadcasting Data saka Server

Kanggo nyebarake data saka server menyang sambungan klien, sampeyan bisa nggunakake cara kaya broadcast ngirim pesen menyang kabeh sambungan utawa send ngirim pesen menyang sambungan tartamtu. Punika conto data siaran saka server:

// ... Initialize WebSocket server  
  
// Broadcast data to all connections  
function broadcast(message) {  
    for(const client of clients) {  
        client.send(message);  
    }  
}  
  
// Handle new connections  
server.on('connection',(socket) => {  
    // Add connection to the list  
    clients.add(socket);  
  
    // Handle incoming messages from the client  
    socket.on('message',(message) => {  
        // Broadcast the message to all other connections  
        broadcast(message);  
    });  
  
    // Handle connection close  
    socket.on('close',() => {  
        // Remove the connection from the list  
        clients.delete(socket);  
    });  
});  

Langkah 2: Integrasi WebSocket ing Node.js Aplikasi

Kanggo nggabungake WebSocket menyang Node.js aplikasi, sampeyan kudu nggawe WebSocket sambungan ing kode JavaScript. Iki minangka conto nggabungake WebSocket ing sisih klien aplikasi sampeyan:

// Initialize WebSocket connection from the client  
const socket = new WebSocket('ws://localhost:8080');  
  
// Handle incoming messages from the server  
socket.onmessage =(event) => {  
    const message = event.data;  
    // Process the received message from the server  
    console.log('Received message:', message);  
};  
  
// Send a message from the client to the server  
function sendMessage() {  
    const messageInput = document.getElementById('messageInput');  
    const message = messageInput.value;  
    socket.send(message);  
    messageInput.value = '';  
}  

Kesimpulan

Kanthi nyebarake data lan nggabungake WebSocket ing Node.js, sampeyan bisa mbangun aplikasi wektu nyata sing interaktif lan responsif. Iki nambah pengalaman pangguna lan mbisakake interaksi wektu nyata antarane aplikasi klien lan server.
