A very simple Node/Express app, to get you started

	const express = require('express'); //Import the express dependency
	const app = express(); //Instantiate an express app, the main work horse of this server
	const port = 5000; //Save the port number where your server will be listening

	//Idiomatic expression in express to route and respond to a client request
	app.get('/', (req, res) => { //get requests to the root ("/") will route here
	res.sendFile('index.html', {root: __dirname}); //server responds by sending the index.html file to the client's browser
	//the .sendFile method needs the absolute path to the file, see: https://expressjs.com/en/4x/api.html#res.sendFile
	});
