Noah is a boilerplate for compiling front-end web apps using NPM build scripts.

Why NPM scripts?

  • Fewer dependencies (no need for Grunt/Gulp, and their respective task wrappers)
  • Speed (by the time you click from your text editor to your browser, your code has already been recompiled and injected into the browser)
  • More Total control over your build steps
  • Future proof (protect your project from time-travellers)

Why Noah?

Compile, test and depoly code on the fly as you develop

  • Includes everything required to get going off the bat
  • Adaptable/scalable to suit your project
  • Built for the modern front-end developer
  • Favours API usage over CLI wrappers

What's included?

  • CSS/Sass lint | autoprefix | compile
  • JS concatenate | uglify | lint | unit test
  • Assemble/Handlebars
  • Browsersync + watching & live reload
  • Git pre-commit hook - never commit bad code again
  • General tasks



All plugins use pure Node.js bindings, so the only things required are:

  • Node.js
  • NPM

Noah is a boilerplate rather than a dependency, so you may wish to fork this repo for your starting point. Noah is still available as an npm package, however:

npm install noah-npm


Core Tasks

Task Description Execute
Assemble Compile handlebars templates npm run assemble
Browsersync Start a new server and watch JS/CSS files npm run browsersync
Clean Clean/empty a directory npm run clean
Concat Concatenate multiple files npm run concat
Copy Copy files to a new location npm run copy
JS-lint Lint JS files npm run jshint
Karma Run JS unit tests npm run test
PostCSS Run Autoprefixer npm run postcss
Sass Compile Sass npm run sass
Sass-lint Lint Sass files npm run scsslint
Uglify Uglify JS files npm run uglify

Asset Tasks

Task Description Execute
Images Copy images to dist directory npm run images
CSS Compile Sass and run Autoprefixer npm run css
JS Concatenate and uglify JS files npm run js

Combined Tasks

Run specific tasks from above in a specific order

Task Description Execute
Compile Runs scsslint, jshint, clean, css, js & images tasks npm run compile
Build Runs compile and templates tasks npm run build
Serve Runs build and browsersync tasks npm run serve
Go Short alias for browsersync task npm run go
CI Reserved for continuous integration tools, e.g. Travis/Jenkins npm run ci


Most executable tasks have their own .js file * (found in the /build/tasks/ directory) which is where your project specific details are passed for that task. Executing a task typically looks something like:

    option : value

The corresponding entry in package.json would look something like:

"scripts": {
    "yourTask": "node ./build/tasks/task.js"

And is executed from the command line by:

npm run yourTask

* Currently the jshint and scsslint tasks are executed via their CLI interface, as opposed to their API, pending future investigation.

Each task has a default, basic-usage example, which will likely need to be modified for your project. Ensure you go through each task and check the options reflect your project's structure. For example, if your project requires two CSS files to be compiled, you may have something like this in your /build/tasks/sass.js file:

// Theme
    src : 'assets/styles/themes/internal.scss',
    dest: 'public/styles/internal.css'

// Print
    src : 'assets/styles/themes/print.scss',
    dest: 'public/styles/print.css'

No matter how many entries you have, they will all be executed when running npm run sass from the command line.

Whilst Noah comes with everything you might need to get going, you still may wish to expand upon the default tasks. Every new task will need its own .js task file configured, which, depending on the plugin, may or may not be simple to do.

Noah comes with some useful additional tools to facilitate development of new tasks.


This helper module is used to get an array of files from a specified directory.

var filePaths = require('./file-paths').filePaths;
var components = filePaths('assets/_js/components/'); // returns all files in this directory
