# angular-seed — the seed for AngularJS apps



This project is an application skeleton for a typical [AngularJS](http://angularjs.org/) web app.

You can use it to quickly bootstrap your angular webapp projects and dev environment for these

projects.



The seed contains a sample AngularJS application and is preconfigured to install the Angular

framework and a bunch of development and testing tools for instant web development gratification.



The seed app doesn't do much, just shows how to wire two controllers and views together.



## Getting Started



To get you started you can simply clone the angular-seed repository and install the dependencies:



### Prerequisites



You need git to clone the angular-seed repository. You can get git from

[http://git-scm.com/](http://git-scm.com/).



We also use a number of node.js tools to initialize and test angular-seed. You must have node.js and

its package manager (npm) installed.  You can get them from [http://nodejs.org/](http://nodejs.org/).



### Clone angular-seed



Clone the angular-seed repository using [git][git]:



```

git clone https://github.com/angular/angular-seed.git

cd angular-seed

```



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



```bash

git clone --depth=1 https://github.com/angular/angular-seed.git 

```



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.



* We get the tools we depend upon via `npm`, the [node package manager][npm].

* We get the angular code via `bower`, a [client-side code package manager][bower].



We have preconfigured `npm` to automatically run `bower` so we can simply do:



```

npm install

```



Behind the scenes this will also call `bower install`.  You should find that you have two new

folders in your project.



* `node_modules` - contains the npm packages for the tools we need

* `app/bower_components` - contains the angular framework files



*Note that the `bower_components` folder would normally be installed in the root folder but

angular-seed changes this location through the `.bowerrc` file.  Putting it in the app folder makes

it easier to serve the files by a webserver.*



### 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][karma]. 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][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][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][travis] 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.
