Our vision is to create consistent Adobe experiences by providing a complete, easy to use library of HTML components compatible with major frameworks.

Coral Spectrum derives from Custom Elements v1 with native support thanks to broad collaboration between browser vendors. The use of custom elements gives us the ability to hide many implementation details from the consumer, allowing much more freedom to change the underlying markup that supports those elements. This makes the exposed API smaller and more explicit, resulting in a lower risk of updates to Coral Spectrum needing to introduce breaking changes.

The current default theme is is an implementation of the Spectrum design specifications, Adobe’s design system. Spectrum provides elements and tools to help product teams work more efficiently, and to make Adobe’s applications more cohesive.

Coral Spectrum leverages the Spectrum CSS framework to style components including the Spectrum SVG icons.

All components can be seen in action here. These are only examples and don't cover all scenarios. The API documentation can be found in the references.
A playground is available here to experiment and preview code with the latest Coral Spectrum version. Code can be shared by copy pasting the URL. The playground is sandboxed to prevent security risks.

The easiest way to consume Coral Spectrum is to download the distribution package of the latest release by running npm i @adobe/coral-spectrum. It includes all components and styles.

After you've unzipped the package, look for the dist folder and :

• Copy the files from dist/css, dist/js and dist/resources in your project.
• Reference the files in your page with :

<link rel="stylesheet" href="css/coral.min.css">
<script src="js/coral.min.js" data-coral-icons="PATH_TO_RESOURCES_FOLDER"></script>

• That's it. Now you're ready to use Coral Spectrum.
• Note: Calendar, Clock and Datepicker components will leverage moment.js if loaded on the page

If your project only requires a few components, you can use a module bundler like Webpack to only import the components needed. Below is an example of a Webpack config:

const path = require('path');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const OptimizeCssAssetsPlugin = require('optimize-css-assets-webpack-plugin');

module.exports = {
  mode: 'production',
  devtool: 'source-map',
  entry: './src/index.js',
  output: {
    filename: 'bundle.min.js',
    path: path.resolve(__dirname, 'dist')
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        use: {
          loader: 'babel-loader',
          options: {
            presets: ['@babel/preset-env']
          }
        }
      },
      {
        test: /\.svg$/,
        use: [
          {
            loader: 'file-loader',
            options: {
              name: 'icons/[name].[ext]'
            },
          },
        ]
      },
      {
        test: /\.css$/,
        use: [MiniCssExtractPlugin.loader, 'css-loader']
      }
    ]
  },
  plugins: [
    new MiniCssExtractPlugin({
      filename: 'style.min.css'
    }),
    new OptimizeCssAssetsPlugin({
      assetNameRegExp: /style\.min\.css$/g,
      cssProcessor: require('cssnano'),
      cssProcessorPluginOptions: {
        preset: ['default', { discardComments: { removeAll: true } }],
      }
    })
  ]
};  

Then in your index.js file, you can import and use single components :

// Import Component
import {Button} from '@adobe/coral-spectrum/coral-component-button';

const button = new Button();

If icons are not displayed, ensure the path to the styles and icons are set e.g. :

<link rel="stylesheet" href="dist/style.min.css">
<script data-coral-icons="dist/icons/" src="dist/bundle.min.js"></script>

Run the following commands first :

npm install -g gulp-cli
npm install

You can use below tasks to get started:

• gulp to generate the build in the dist folder and run the dev server on localhost:9001 by default.
• gulp build to generate the build in the dist folder.
• gulp dev to run the dev server on localhost:9001 by default.
• gulp test to run the tests. Test reports are in dist/coverage.
• gulp docs to build the documentation in dist/documentation.

Each component can be built independently e.g. cd coral-component-button && gulp.

We are currently releasing this package on npm.

Before we get started, clean up your dependencies with the following command :

git checkout master
rm -rf node_modules && npm install

Then run gulp release. You'll be asked to bump the version (minor version bump by default). Coral Spectrum is following semantic versioning (either patch, minor or major).

The command will take care of increasing, tagging the version and publishing the package to npm.

If everything went well, run gulp deploy to publish the documentation on the gh-pages branch else revert the version bump.
