ember-cli

What is ember-cli?

Ember CLI is the command line interface for managing and developing Ember.js applications. It provides a robust set of tools for scaffolding, building, testing, and deploying Ember.js applications.

What are ember-cli's main functionalities?

Project Creation

This command creates a new Ember.js application with the name 'my-app'. It sets up the project structure, installs dependencies, and configures the build system.

ember new my-app

Generating Blueprints

This command generates a new component called 'my-component'. Blueprints are templates for generating various parts of an Ember.js application, such as components, routes, and services.

ember generate component my-component

Running the Development Server

This command starts a local development server, allowing you to preview your application in the browser. It also watches for file changes and automatically reloads the application.

ember serve

Building the Application

This command builds the Ember.js application for production. It optimizes the assets and outputs them to the 'dist' directory, ready for deployment.

ember build --environment production

Running Tests

This command runs the application's test suite. Ember CLI supports both unit and integration tests, and it can be configured to run tests in different environments.

ember test

Other packages similar to ember-cli

create-react-app

Create React App is a command line tool for creating and managing React applications. It provides a similar set of features to Ember CLI, including project scaffolding, development server, and build tools. However, it is tailored specifically for React applications.

vue-cli

Vue CLI is the standard tooling for Vue.js development. It offers a similar feature set to Ember CLI, including project creation, development server, and build tools. Vue CLI also provides a plugin system for extending its functionality.

angular-cli

Angular CLI is the command line interface for Angular applications. It provides tools for generating components, services, and other parts of an Angular application, as well as running a development server and building the application for production. It is similar to Ember CLI but tailored for Angular.

Development Hints

Working with master

git clone https://github.com/stefanpenner/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.

Working with the tests

Use npm run autotest to run the tests after every file change (Runs only fast tests). Use npm test to run them once.

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.

Problems

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://0.0.0.0:4200
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
