What are some popular WebSocket libraries I can use for my project?

Some popular WebSocket libraries include Socket.IO, ws for Node.js, and WebSocket API for browsers. Do you have a specific language in mind?

I'm using Node.js. Can you tell me more about the 'ws' library?

The 'ws' library is a simple and efficient WebSocket library for Node.js. It's lightweight and supports both server and client implementations.

How do I install and use 'ws' in my Node.js application?

You can install 'ws' using npm with the command npm install ws. To use it, require it in your code and create a WebSocket server or client.

Can you provide a basic example of a WebSocket server using 'ws'?

Sure! Here's a simple example:

const WebSocket = require('ws');
const server = new WebSocket.Server({ port: 8080 });

server.on('connection', socket => {
  socket.on('message', message => {
    console.log(`Received: ${message}`);
    socket.send(`Hello, you sent -> ${message}`);
  });
});
