This project is an application skeleton for a typical AngularJS 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.
To get you started you can simply clone the angular-seed repository and install the dependencies:
Clone the angular-seed repository using git:
git clone https://github.com/angular/angular-seed.git
cd angular-seed
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. - We get the angular code via
bower
, a client-side code package manager.
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 needbower_components
- contains the angular framework files
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
.
app/ --> all of the files to be used in production
css/ --> css files
app.css --> default stylesheet
img/ --> image files
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
js/ --> javascript files
app.js --> application
controllers.js --> application controllers
directives.js --> application directives
filters.js --> custom angular filters
services.js --> custom angular services
partials/ --> angular view partials (partial html templates)
partial1.html
partial2.html
test/ --> test config and source files
protractor-conf.js --> config file for running e2e tests with Protractor
e2e/ --> end-to-end specs
scenarios.js
karma.conf.js --> config file for running unit tests with Karma
unit/ --> unit level specs/tests
controllersSpec.js --> specs for controllers
directivessSpec.js --> specs for directives
filtersSpec.js --> specs for filters
servicesSpec.js --> specs for services
There are two kinds of tests in the angular-seed application: Unit tests and End to End tests.
The angular-seed app comes preconfigured with unit tests. These are written in Jasmine, which we run with the Karma Test Runner. We provide a Karma configuration file to run them.
- the configuration is found at
test/karma.conf.js
- the unit tests are found in
test/unit/
.
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 you 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
The angular-seed app comes with end-to-end tests, again written in 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
test/protractor-conf.js
- the end-to-end tests are found in
test/e2e/
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.
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.
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.
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://
.
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 server static files, from a folder, by running:
http-server
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.
This really depends on how complex is your app 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, where 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).
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 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.
