Simple Express server to serve static files

server.js

/*
 | Super simple Express server for serving files
 | Note: Don't forget to npm install express!

const express = require('express');

const path = require('path');

/*
 | Send index file on root visit.
 | Note: By default this code will serve an 'index.html'  
 | file in the same (root) directory as the server.
 */
app.get('/', function(req, res) {
    res.sendFile(path.join(__dirname, 'index.html'));

/*
 | Make additional static files available (ex: css/js files, etc).
 | Note: This setup will use all files in the root directory.
 | Since this might not be secure/desirable, it might be best to
 | create a new directory (ie. public) and append to "__dirname".
 |
 | The first param ('/') is how the static files are reached in
 | href/src tags. (ex: '/' = <script src="scripts.js"> in a view)
 |
 | If this 1st param is changed to something like "public" (instead of '/'),
 | static files would be accessed by: <script src="public/scripts.js"> in a view
