Ember.js also provides access to the most advanced features of Javascript, HTML and the Browser giving you everything you need to create your next killer web app.

Building Ember.js

Ensure that Node.js and bower are installed.
Run git clone https://github.com/emberjs/ember.js.git && cd ember.js.
Run git config core.symlinks true to ensure that symlinks are enabled.
Run git reset --hard HEAD to reset to HEAD with symlinks.
Run npm install to ensure the required dependencies are installed.
Run bower install to ensure required web dependencies are installed.
Run npm run build to build Ember.js. The builds will be placed in the dist/ directory.

npm install troubleshooting

If you encounter a problem with downloading dependencies like:

npm ERR! registry error parsing json

consider upgrading npm with:

npm install -g npm@latest

You can find more information in Upgrading on *nix (OSX, Linux, etc.) npm wiki page.

How to Run Unit Tests

Pull requests should pass the Ember.js unit tests. Do the following to run these tests.

Follow the setup steps listed above under Building Ember.js.
To start the development server, run npm start.
To run all tests, visit http://localhost:4200/.
To test a specific package, visit http://localhost:4200/tests/index.html?package=PACKAGE_NAME. Replace PACKAGE_NAME with the name of the package you want to test. For example:

To test multiple packages, you can separate them with commas.

You can also pass jquery=VERSION in the test URL to test different versions of jQuery.

From the CLI

Install phantomjs from http://phantomjs.org.
Run npm test to run a basic test suite or run TEST_SUITE=all npm test to run a more comprehensive suite.

From ember-cli

ember test --server
connect the browsers you want
if phantom didn't connect automatically, you can run ./bin/connect-phantom-to <optional-port>

To run a specific browser, you can use the --launch flag

ember test --server --launch SL_Firefox_Current
ember test --launch SL_Firefox_Current
