Modules - builtin and custom 

https://www.w3schools.com/nodejs/nodejs_modules.asp

exports.myDateTime = function () {
  return Date();
};

Use the exports keyword to make properties and methods available outside the module file.

Save the code above in a file called "myfirstmodule.js

Include modules with require

var http = require('http');
var dt = require('./myfirstmodule');

http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/html'});
  res.write("The date and time are currently: " + dt.myDateTime());
  res.end();
}).listen(8080);

Http module to create a server

Need a header record for type 

Pass req, res variables to set request, get response

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/html'});
  res.write(req.url);
  res.end();
}).listen(8080);

NPM package manager installed with Node.js

https://www.w3schools.com/nodejs/nodejs_npm.asp

NPM is a package manager for Node.js packages, or modules if you like.

www.npmjs.com hosts thousands of free packages to download and use.

The NPM program is installed on your computer when you install Node.js

A package in Node.js contains all the files you need for a module.

Modules are JavaScript libraries you can include in your project.

npm install mypackage

Events module

https://www.w3schools.com/nodejs/nodejs_events.asp

you can create-, fire-, and listen for- your own events.

Similar to Java beans where events are built-in with create event, addListener, fireEvent

Objects in Node.js can fire events, like the readStream object fires events when opening and closing a file:

Create eventEmitter

var events = require('events');
var eventEmitter = new events.EventEmitter();
