Angular-base: modular platform for your AngularJS apps

Build-Status Dependencies Dev-dependencies

This repository is a modular abstraction to build a typical AngularJS web application. You can use it to quickly scaffold your Angular web app projects and dev environment for these projects.

This seed should clarify how to wire up all the modules of your application, even when we understand that in some cases there must be some changes needed by the structure to fit your needs correctly.

Getting Started

To get you started, let's see what you need after cloning the repository and install the dependencies:

Prerequisites

You need git to clone the Angular base repository from Github. You can get git from git-scm.com.

We also use a number of node.js tools to initialize and test Angular-base. You must have node.js and its package manager (npm) installed. In addition you'll need Bower to manage the angular modules/dependencies that we've included in the project by default. You can get them from nodejs.org and bower.io.

Clone Angular-base

Clone the angular-base repository using git:

git clone https://github.com/atsistemas/angular-base.git
cd angular-base

If you just want to start a new project without the angular-base commit history then you can do:

git clone --depth=1 https://github.com/angular/angular-base.git <your-project-name>

The depth=1 tells git to only pull down one commit worth of historical data.

Install Dependencies

We have two kinds of dependencies in this project: tools and angular framework code. The tools help us manage and test the application.

So with this in mind we have to run the install command for both npm and bower, so we can do it like:

npm install;bower install;

You should find that you have the two new folders here mentioned in your project:

  • /node_modules - contains the npm packages for the tools we need
  • /bower_components - contains the angular framework files

Run the Application

We have preconfigured the project with a simple development web server. The simplest way to start this server is:

npm start

Now browse to the app at http://localhost:8000/app/index.html.

Directory Layout

app/                    --> all of the source files for the application
  app.css               --> default stylesheet
  components/           --> all app specific modules
    version/              --> version related components
      version.js                 --> version module declaration and basic "version" value service
      version_test.js            --> "version" value service tests
      version-directive.js       --> custom directive that returns the current app version
      version-directive_test.js  --> version directive tests
      interpolate-filter.js      --> custom interpolation filter
      interpolate-filter_test.js --> interpolate filter tests
  view1/                --> the view1 view template and logic
    view1.html            --> the partial template
    view1.js              --> the controller logic
    view1_test.js         --> tests of the controller
  view2/                --> the view2 view template and logic
    view2.html            --> the partial template
    view2.js              --> the controller logic
    view2_test.js         --> tests of the controller
  app.js                --> main application module
  index.html            --> app layout file (the main html template file of the app)
  index-async.html      --> just like index.html, but loads js files asynchronously
karma.conf.js         --> config file for running unit tests with Karma
e2e-tests/            --> end-to-end tests
  protractor-conf.js    --> Protractor config file
  scenarios.js          --> end-to-end scenarios to be run by Protractor

Testing

There are two kinds of tests in the angular-seed application: Unit tests and End to End tests.

Running Unit Tests

The angular-seed app comes preconfigured with unit tests. These are written in [Jasmine][jasmine], which we run with the Karma Test Runner. We provide a Karma configuration file to run them.

  • the configuration is found at karma.conf.js
  • the unit tests are found next to the code they are testing and are named as ..._test.js.

The easiest way to run the unit tests is to use the supplied npm script:

npm test

This script will start the Karma test runner to execute the unit tests. Moreover, Karma will sit and watch the source and test files for changes and then re-run the tests whenever any of them change. This is the recommended strategy; if your unit tests are being run every time you save a file then you receive instant feedback on any changes that break the expected code functionality.

You can also ask Karma to do a single run of the tests and then exit. This is useful if you want to check that a particular version of the code is operating as expected. The project contains a predefined script to do this:

npm run test-single-run

End to end testing

The angular-seed app comes with end-to-end tests, again written in [Jasmine][jasmine]. These tests are run with the Protractor End-to-End test runner. It uses native events and has special features for Angular applications.

  • the configuration is found at e2e-tests/protractor-conf.js
  • the end-to-end tests are found in e2e-tests/scenarios.js

Protractor simulates interaction with our web app and verifies that the application responds correctly. Therefore, our web server needs to be serving up the application, so that Protractor can interact with it.

npm start

In addition, since Protractor is built upon WebDriver we need to install this. The angular-seed project comes with a predefined script to do this:

npm run update-webdriver

This will download and install the latest version of the stand-alone WebDriver tool.

Once you have ensured that the development web server hosting our application is up and running and WebDriver is updated, you can run the end-to-end tests using the supplied npm script:

npm run protractor

This script will execute the end-to-end tests against the application being hosted on the development server.

Updating Angular

Previously we recommended that you merge in changes to angular-seed into your own fork of the project. Now that the angular framework library code and tools are acquired through package managers (npm and bower) you can use these tools instead to update the dependencies.

You can update the tool dependencies by running:

npm update

This will find the latest versions that match the version ranges specified in the package.json file.

You can update the Angular dependencies by running:

bower update

This will find the latest versions that match the version ranges specified in the bower.json file.

Loading Angular Asynchronously

The angular-seed project supports loading the framework and application scripts asynchronously. The special index-async.html is designed to support this style of loading. For it to work you must inject a piece of Angular JavaScript into the HTML page. The project has a predefined script to help do this.

npm run update-index-async

This will copy the contents of the angular-loader.js library file into the index-async.html page. You can run this every time you update the version of Angular that you are using.

Serving the Application Files

While angular is client-side-only technology and it's possible to create angular webapps that don't require a backend server at all, we recommend serving the project files using a local webserver during development to avoid issues with security restrictions (sandbox) in browsers. The sandbox implementation varies between browsers, but quite often prevents things like cookies, xhr, etc to function properly when an html page is opened via file:// scheme instead of http://.

Running the App during Development

The angular-seed project comes preconfigured with a local development webserver. It is a node.js tool called http-server. You can start this webserver with npm start but you may choose to install the tool globally:

sudo npm install -g http-server

Then you can start your own development web server to serve static files from a folder by running:

http-server -a localhost -p 8000

Alternatively, you can choose to configure your own webserver, such as apache or nginx. Just configure your server to serve the files under the app/ directory.

Running the App in Production

This really depends on how complex your app is and the overall infrastructure of your system, but the general rule is that all you need in production are all the files under the app/ directory. Everything else should be omitted.

Angular apps are really just a bunch of static html, css and js files that just need to be hosted somewhere they can be accessed by browsers.

If your Angular app is talking to the backend server via xhr or other means, you need to figure out what is the best way to host the static files to comply with the same origin policy if applicable. Usually this is done by hosting the files by the backend server or through reverse-proxying the backend server(s) and webserver(s).

Continuous Integration

Travis CI

Travis CI is a continuous integration service, which can monitor GitHub for new commits to your repository and execute scripts such as building the app or running tests. The angular-seed project contains a Travis configuration file, .travis.yml, which will cause Travis to run your tests when you push to GitHub.

You will need to enable the integration between Travis and GitHub. See the Travis website for more instruction on how to do this.

CloudBees

CloudBees have provided a CI/deployment setup:

If you run this, you will get a cloned version of this repo to start working on in a private git repo, along with a CI service (in Jenkins) hosted that will run unit and end to end tests in both Firefox and Chrome.
