Aura is a UI framework for developing dynamic web apps for mobile and desktop devices, while providing a scalable long-lived lifecycle to support building apps engineered for growth. It supports partitioned multi-tier component development that bridges the client and server.

To find out more about Aura, see the Aura Documentation site.

You can build your user interface at a granular level and easily integrate with popular toolkits and libraries, such as jQuery. Aura's lightweight and scalable architecture uses two key building blocks: components and events.

Components use markup that looks similar to HTML. You can also use HTML or any other code that can execute within an HTML page. Components are encapsulated and their internals stay private. You can extend existing components to customize their behavior.

The robust event model enables you to develop loosely coupled components. Once you define the events that interact with your components, your team can work on the components in parallel to quickly build a powerful app.

Aura also supports a powerful expression language, embedded testing, performance, and security features.

The easiest way to get up and running is from the command line, but you can easily use Aura with your favorite IDE too.

You need:

• JDK 1.7
• Apache Maven 3

1. Open a command line window.

2. Navigate to the directory where you want to create your project template and run:

   mvn archetype:generate -DarchetypeCatalog=http://repo.auraframework.org/libs-release-local/archetype-catalog.xml

3. When prompted to choose an archetype, enter 1.

4. Select the latest archetype version, or press enter for the default version. The archetype is downloaded to your machine.

5. Enter these values:

    Define value for property 'groupId': org.myGroup
    Define value for property 'artifactId': helloWorld
    Define value for property 'version': 1.0-SNAPSHOT
    Define value for property 'package': org.myGroup

**Note**: The artifactId can only contain alphanumeric characters.

6. When prompted to confirm properties configuration, enter Y. The following output confirms that your template has been generated successfully.

1. On the command line, navigate to the directory for your new app.

   cd helloWorld

2. Build the app.

   mvn clean install

3. Start the Jetty server on port 8080.

   mvn jetty:run

   To use another port, append: -Djetty.port=portNumber. For example, mvn jetty:run -Djetty.port=9877.

4. Test your app in a browser by navigating to:

   http://localhost:8080/helloWorld/helloWorld.app
   You should see a simple greeting in your browser.

5. To stop the Jetty server and free up the port when you are finished, press CTRL+C on the command line.

   Note: the helloWorld/pom.xml file has a <dependencies> section, which lists the <version> of each Aura artifact in your project. They define the version of Aura that your project is using and each artifact should use the same version.

Now that you've created your first app, you might be wondering where do I go from here? There is much more to learn about Aura. Here are a few ideas for next steps.

See the Aura Documentation site.

Alternatively, you can start up your Jetty server and navigate to http://localhost:8080/auradocs/docs.app to access the documentation on your localhost.
