AngularJS component library generator

Yeoman generator to create standalone AngularJS component libraries in seconds!

Build Status


In short

If you want to create a standalone library with filters, directives, services, etc for use in your AngularJS applications, then this generator may just be what you need.

The generator automatically:

  • creates a complete directory structure with boilerplate code for your AngularJS library
  • creates a complete directory structure for your tests
  • configures Gulp to build your code and automate testing
  • sets up Karma to run your unit tests using Mocha, Chai and Sinon

This generator is NOT made to generate complete AngularJS applications. If you want to generate a complete AngularJS web application with routes, views, etc then please use generator-angular.

Quick start

Make sure you have yeoman installed:

$ npm install -g yo

Install the generator:

$ npm install -g generator-angularjs-library

Create a new project directory:

$ mkdir sample-project
cd sample-project


$ yo angularjs-library

Answer the questions and the generator will create the boilerplate for your library:


What the generator does for you

The generator automatically:

  • creates a src directory structure with the boilerplate code for your AngularJS library
  • creates a test directory structure to store your unit tests and e2e tests
  • creates initial unit tests in the test/unit/ directory
  • creates a custom gulpfile.js to build, minify and uglify your library
  • creates a custom karma-src.conf.js to let karma run your unit tests
  • creates a custom karma-dist-concatenated.conf.js to let karma run your unit tests
  • creates a custom karma-dist-minified.conf.js to let karma run your unit tests
  • creates a custom bower.json with necessary devDependencies and appropriate ignore files
  • creates a custom package.json file for your library
  • creates a custom .travis.yml file to enable travis support
  • creates a custom .jshintrc to support angular global during syntax check
  • creates a custom file
  • creates a custom LICENSE file

How to use the generated boilerplate

The basic library structure is automatically created for you in the src folder.

You can edit the existing files or add additional files in the src folder to add components to your library.

Once you have added files in the src directory, you can update the files in the dist directory using:

$ gulp

First gulp will

  • check the JavaScript syntax of src/**/*.js
  • run all unit tests using the code in your src directory

to make sure the code is fine.

Then all files in the src directory will be concatenated into 2 files in the dist directory:

  • <your-library-name>.js: regular version of your library to use in a development environment
  • <your-library-name>.min.js: minified version of your library to use in a production environment


Manually testing your code

The generator creates 3 configurations for unit testing:

  • karma-src.conf.js: run unit tests using src/**/*.js
  • karma-dist-concatenated.conf.js: run unit tests using dist/<your-library-name>.js
  • karma-dist-minified.conf.js: run unit tests using dist/<your-library-name>.min.js

By default, gulp will run karma-src.conf.js, but you can use the following preconfigured Gulp tasks to specify the suite you want to run:

# Run unit tests using src/**/*.js 
$ gulp test-src
# Run unit tests using dist/<your-library-name>.js 
$ gulp test-dist-concatenated
# Run unit tests using dist/<your-library-name>.min.js 
$ gulp test-dist-minified


This allows you to unit test the different builds of your code to ensure they all work as expected.

How to write a test

Suppose you have a service:

// src/my-lib/services/some-service.js 
  .service('someService', function() { = function() {
      return 1234;

Then you write a test like this:

describe('someService', function() {
  var someService;
  // load the module 
  // inject the service 
  beforeEach(inject(function(_someService_) {
    someService = _someService_;
  it('should exist', function() {
  it('should have a method called foo', function() {
