Command line tool for developing ambitious ember.js apps

The Ember.js command line utility.

Supports node 0.12.x and npm 2.7.x and 3.x.

Additional components of this project that are used at runtime in your application:

git clone https://github.com/ember-cli/ember-cli.git
cd ember-cli
npm link

npm link is very similar to npm install -g except that instead of downloading the package from the repo the just cloned ember-cli/ folder becomes the global package. Any changes to the files in the ember-cli/ folder will immediately affect the global ember-cli package.

Now you can use ember-cli via the command line:

ember new foo
cd foo
npm link ember-cli
ember server

npm link ember-cli is needed because by default the globally installed ember-cli just loads the local ember-cli from the project. npm link ember-cli symlinks the global ember-cli package to the local ember-cli package. Now the ember-cli you cloned before is in three places: The folder you cloned it into, npm's folder where it stores global packages and the ember-cli project you just created.

If you upgrade an app running against Ember CLI master you will need to re-link to your checkout of Ember CLI by running npm link ember-cli in your project again.

Please read the official npm-link documentation and the npm-link cheatsheet for more information.

Use npm test to run the tests (Runs only fast tests).

For a full test run which includes some very slow acceptance tests, please run: npm run test-all. Please note, this is what travis runs.

To exclude a test or test suite append a .skip to it() or describe() respectively (e.g. it.skip(...)). To focus on a certain test or test suite append .only.

Please read the official mocha documentation for more information.

When running ember cli it could happen that a lack of file watches can occur. You will get an error message like:

Serving on http://localhost:4200
watch ENOSPC
Error: watch ENOSPC
    at errnoException (fs.js:1019:11)
    at FSWatcher.start (fs.js:1051:11)

This problem will be corrected in future releases. The following line is a workaround to get the server up and running until this problem is fixed. See Issue 1054.

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

For Arch Linux or Manjaro Linux, in order for the parameters to be loaded at boot, the kernel sysctl parameters have to be saved in a drop-in directory instead of sysctl.conf.

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.d/99-sysctl.conf && sudo sysctl --system

If all pull requests are breaking on the same issue, we likely have a dependency that updated and broke our CI. This app can tell you which packages updated.
