Making it easier to build the internet.


Enginemill is a Node.js web development framework. The goal is to codify some opinions about how to structure a Node.js system and provide tools to make the development of your systems easier and more fun.

  • Bluebird for Promises.
  • Lodash (Underscore) too.
  • Filepath to work with the filesystem.
  • Yargs to parse command line options.
  • Moment to parse, validate, manipulate and display dates.
  • Numeral for Number formatting and manipulation.
  • An Object factory for composing mixins.
  • Serially load plugins you define and kicks off your app only when they have all loaded.
  • Comprehensive logging based on Bunyan.
  • Message and pattern based communication with Oddcast.
  • Promisified request wrapper for making HTTP requests.
  • Supports CoffeeScript out of the box, which is nice for config and plugin initialization files.

Here is an example of booting up a new Express.js web application:

In ./bin/start-server.js:

var enginemill = require('enginemill');
// Loads the filepath (https://github.com/kixxauth/filepath) module. 
var path = enginemill.path;
var server = require('../server');
    appdir: path.create(__dirname, '..'),
    // Plugins (expected in appdir/initializers/). 
    initializers: [
.catch(function (err) {
    console.error('There was an error starting the server:');
    console.error(err.stack || err.message || err);

In './initializers/configs.coffee' (configs plugin):

enginemill = require 'enginemill'
path       = enginemill.path
module.exports = (app) ->
    # app.environment is set with the --environment option, or the
    # NODE_ENV environment variable.
    app.configs.port = if app.environment is 'production' then 8080 else 3000
    # Set the public path to '../public'
    app.configs.public_path = path.create(__dirname, '..', 'public')

In './initializers/middleware.coffee':

express = require 'express'
module.exports = (app) ->
    app.API.httpApp = express()
    app.API.httpApp.use bodyParser.json()
    app.API.httpApp.use bodyParser.urlencoded({ extended: false })
    app.API.httpApp.use cookieParser()
    app.API.httpApp.use express.static(app.configs.public_path.toString())

In './initializers/routes.coffee':

dashboard = require '../presenters/dashboard'
module.exports = (app) ->
    app.API.httpApp.get '/', dashboard.get

In ./server.js:

var http = require('http');
var enginemill = require('enginemill');
// Loads Underscore/Lodash as 'U' symbol. 
var U = enginemill.U;
exports.start = function (app) {
    var port = app.configs.port;
    // Set the port number in Express. 
    app.httpApp.set('port', port);
    // Setup the server 
    var server = http.createServer(app.httpApp);
    server.on('listening', U.partial(exports.onServerListening, server));
exports.onServerListening = function (server) {
    var addr = server.address();
    console.log('Listening on %s:%s', addr.address, addr.port);
    console.log('press CTRL-C to stop');

Run the server with node ./bin/start-server.js --environment production;
