Frontend Web Development: The Big Nerd Ranch Guide Chapter 16: Real-Time Communication with WebSocket

I put the following in chatbot.js, which I added a require of in index.js:

var WebSocket = require(‘ws’);
var chatClient = new WebSocket(‘http://localhost:3001’);
var myName = ‘Steve’;

chatClient.on(‘open’, function open() {
chatClient.send('Hello, I am a chatbot name ’ + myName);
});

chatClient.on(‘message’, function incoming(data) {
if (data.indexOf(myName) == 0) {
var ask = data.substring(myName.length); // remove myName
ask = ask.replace(/^[ ,]+/, ‘’); // remove initial commas and spaces
chatClient.send('This is ’ + myName + ', I will ’ + ask);
}
});
