use websockets in javascript

WebSockets provide a real-time communication protocol between a client and a server over a single TCP connection. They are widely used in applications that require a constant exchange of data, such as online gaming, chat applications, and trading platforms. In JavaScript, the WebSocket API provides a straightforward way to implement WebSockets in your projects.

To use WebSockets in JavaScript, you first need to create a WebSocket object, passing the WebSocket URL as a parameter:

index.tsx
const socket = new WebSocket('wss://example.com');

Once you have created the WebSocket object, you can listen for WebSocket events such as open, message, and close, using the addEventListener method:

index.tsx
socket.addEventListener('open', function (event) {
  console.log('WebSocket connection established');
});

socket.addEventListener('message', function (event) {
  console.log('WebSocket message received: ', event.data);
});

socket.addEventListener('close', function (event) {
  console.log('WebSocket connection closed');
});

To send data over the WebSocket connection, you can use the send method:

index.tsx
socket.send('Hello, server!');

On the server side, you can use any WebSocket server implementation to handle the WebSocket requests from the client. Common WebSocket server implementations in Node.js include ws and socket.io.

Overall, using websockets in JavaScript is a powerful way to establish real-time communication with servers, allowing for seamless collaboration and interaction in web applications.
