In Node.js, how do I "include" functions from my other files?

Question

Let's say I have a file called app.js. Pretty simple:

var express = require('express'); var app = express.createServer(); app.set('views', __dirname + '/views'); app.set('view engine', 'ejs'); app.get('/', function(req, res){   res.render('index', {locals: {     title: 'NowJS + Express Example'   }}); });  app.listen(8080); 

What if I have a functions inside "tools.js". How would I import them to use in apps.js?

Or...am I supposed to turn "tools" into a module, and then require it? << seems hard, I rather do the basic import of the tools.js file.

You can require any js file, you just need to declare what you want to expose.

// tools.js // ======== module.exports = {   foo: function () {     // whatever   },   bar: function () {     // whatever   } };  var zemba = function () { } 

And in your app file:

// app.js // ====== var tools = require('./tools'); console.log(typeof tools.foo); // => 'function' console.log(typeof tools.bar); // => 'function' console.log(typeof tools.zemba); // => undefined
