This package wraps the Polymer project's core elements, providing the following features:

• Because the elements are bundled into a single pub package, you can add core_elements as a dependency in your pubspec. You don't need to install npm or bower.
• Core elements that are either performance sensitive (like core-list) or use native objects that are difficult to use via dart:js (like core-ajax) have been ported to Dart.
• The remaining core elements are wrapped with Dart proxy classes, making them easier to interact with from Dart apps.

You can find out more about core elements here: http://www.polymer-project.org/docs/elements/core-elements.html

This is an early access version of the core elements. The elements are still changing on both the JavaScript and Dart sides.

All elements live at the top level of the lib/ folder.

Import into HTML:

<link rel="import" href="packages/core_elements/core_input.html">

Import into Dart:

import 'package:core_elements/core_input.dart';

If you download or fork the repo from https://github.com/dart-lang/core-elements, then you can use the pub command to run demos.

If you only want to run a few demos, then you can edit pubspec.yaml to comment out (using #) all the entrypoints except the ones you need.

To run a core element demo:

1. From the top directory, use the pub serve command, specifying the example directory:

    pub serve example
   

2. In a browser, visit http://localhost:8080/element_name.html).

   Note that you use an underscore (_) instead of the dash (-) in the element name. For example, to see the core-icons demo, browse to http://localhost:8080/core_icons.html.

   For a full list of demos, see the values for entry_points in the pubspec.yaml file.
