Node.js 8 the Right Way

Creating Socket Client Connections

So far in this chapter, we’ve explored the server side of Node.js sockets. Here we’ll write a client program in Node.js to receive JSON messages from our net-watcher-json-service program. We’ll start with a naive implementation, and then improve upon it through the rest of the chapter.

Open an editor and insert this:

networking/net-watcher-json-client.js

'use strict';
const net = require('net');
const client = net.connect({port: 60300});
client.on('data', data => {
  const message = JSON.parse(data);
  if (message.type === 'watching') {
    console.log(`Now watching: ${message.file}`);
  } else if (message.type === 'changed') {
    const date = new Date(message.timestamp);
 console.log( ...
