Flight generator

Get up and running with everything you need to use Twitter's lightweight, JavaScript framework, Flight.

This is a Flight generator for Yeoman. It provides several sub-generators to easily scaffold component, mixin, page, and spec files for applications.

Recommended setup

Install Node.js (which comes with npm). It's best to have npm version 1.2.x or above installed.

Install Bower, Karma, Yo, and the Flight generator. These tools will help fetch and manage your dependencies, generate the boilerplate Flight application, and run your Jasmine unit tests.

npm install -g bower karma yo generator-flight

Make a new directory, and cd into it:

mkdir flight-app && cd $_

You're now ready to generate an app or package!

Main generator

To generate a Flight-based application:

yo flight <app-name>

N.B. All your Node and client-side dependencies will be installed automatically unless you include the --skip-install option.

All generators and their output

Available generators (to be run in the root directory of a project).

• flight <app-name> (aka flight:app)
• flight:component <component-name>
• flight:mixin <mixin-name>
• flight:page <page-name>
• flight:all

flight:app

Scaffolds a Flight application file structure, installs all the library code you need, and correctly configures your test setup. The app generator will prompt you to optionally install Twitter Bootstrap or Normalize.css.

Example:

yo flight

Locally installed software

Automatically installs all the Flight framework dependencies, and sets up a Node-based toolchain for your development workflow.

via Bower

• Flight (and its dependencies: ES5 Shim, jQuery)
• RequireJS
• Jasmine jQuery extensions
• Jasmine Flight extensions
• (optional) Twitter Bootstrap
• (optional) Normalize.css

via npm

• Flight generator (installed as a local dependency)
• Karma unit test runner

flight:component

Generates a component in app/js/component.

Example:

yo flight:component tweet_box

Produces app/js/component/tweet_box.js:

define(function (require) {
  var defineComponent = require('flight/lib/component');

  return defineComponent(tweetBox);

  function tweetBox() {
    this.defaultAttrs({});
    this.after('initialize', function () {});
  }
});

And the test file test/spec/component/tweet_box.spec.js:

describeComponent('component/tweet_box', function () {
  // Initialize the component and attach it to the DOM
  beforeEach(function () {
    setupComponent();
  });

  it('should be defined', function () {
    expect(this.component).toBeDefined();
  });

  it('should do something', function () {
    expect(true).toBe(false);
  });
});

flight:mixin

Generates a mixin component in app/js/component.

Example:

yo flight:mixin tweet_actions

Produces app/js/component/with_tweet_actions.js:

define(function (require) {
  return withTweetActions;

  function withTweetActions() {
    this.defaultAttrs({});
    this.after('initialize', function () {});
  }
});

And the test file test/spec/component/with_tweet_box.spec.js:

describeMixin('component/with_tweet_box', function () {
  // Initialize the component and attach it to the DOM
  beforeEach(function () {
    setupComponent();
  });

  it('should be defined', function () {
    expect(this.component).toBeDefined();
  });

  it('should do something', function () {
    expect(true).toBe(false);
  });
});

flight:page

Generates a page component in app/js/page.

Example:

yo flight:page settings

Produces app/js/page/settings.js:

define(function (require) {
  // var myComponent = require('component/my_component');

  return initialize;

  function initialize() {
    // myComponent.attachTo(document);
  }
});

flight:all

Shortcut that runs flight:app, flight:component my_component, and flight:mixin my_component.

Running your app's tests

The generated app uses a local installation of Karma to run the unit tests. When you have Karma globally installed, it's easy to run and then watch your unit tests in Chrome and Firefox:

karma start

This is the recommended approach because the moment your unit tests start failing, you'll be notified in the terminal.

To run your unit tests just once in PhantomJS (for CI), you must install PhantomJS and the run:

npm test

For further information about configuring Karma, please refer to the Karma website.
