ember-web-app

NOTICE: official repository moved to https://github.com/zonkyio/ember-web-app

This Ember addon helps you configure and manage the web app manifest and related meta tags needed to create a Progressive Web Application

From MDN

The web app manifest provides information about an application (such as name,author, icon, and description) in a text file. The purpose of the manifest isto install web applications to the homescreen of a device, providing userswith quicker access and a richer experience.

Addon features:

  • Generates a manifest.ember-web-app.json file using a JavaScript template
  • Uses fingerprint for images
  • Generates equivalent meta tags for supporting other devices (e.g. iPhone)
  • Validates the configuration

See the documentation section below for more information.

Installation

$ ember install ember-web-app

This generates a config/manifest.js configuration file.

Example

Having the following configuration file config/manifest.js

module.exports = function() {
  return {
    name: "Let's Cook",
    short_name: "Let's Cook",
    description: "An app for organizing your weekly menu and groceries list.",
    start_url: "/",
    display: "standalone",
    background_color: "#ffa105",
    theme_color: "#ffa105",

    icons: [
      {
        src: "/images/icons/android-chrome-192x192.png",
        sizes: "192x192",
        type: "image/png"
      },
      {
        src: "/images/icons/android-chrome-512x512.png",
        sizes: "512x512",
        type: "image/png"
      },
      {
        src: "/images/icons/apple-touch-icon.png",
        sizes: "180x180",
        type: "image/png",
        targets: ['apple']
      },
      {
        src: "/images/icons/mstile-150x150.png",
        element: "square150x150logo",
        targets: ['ms']
      }
    ],

    apple: {
      statusBarStyle: 'black-translucent'
    },

    ms: {
      tileColor: '#ffffff'
    }
  }
}

It will generate the following meta tags

index.html

<link rel="manifest" href="/manifest.webmanifest">

<link rel="apple-touch-icon" href="/images/icons/android-chrome-192x192-883114367f2d72fc9a509409454a1e73.png" sizes="192x192">
<link rel="apple-touch-icon" href="/images/icons/android-chrome-512x512-af3d768ff652dc2be589a3c22c6dc827.png" sizes="512x512">
<link rel="apple-touch-icon" href="/images/icons/apple-touch-icon-36cba25bc155e8ba414265f9d85861ca.png" sizes="180x180">

<meta name="theme-color" content="#ffa105">

<meta name="apple-mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-title" content="Let's Cook">
<meta name="apple-mobile-web-app-status-bar-style" content="black-translucent">

<meta name="msapplication-config" content="/browserconfig.xml">

and the following manifest.webmanifest file

{
  "name": "Let's Cook",
  "short_name": "Let's Cook",
  "description": "An app for organizing your weekly menu and groceries list.",
  "start_url": "/",
  "display": "standalone",
  "background_color": "#ffa105",
  "theme_color": "#ffa105",
  "icons": [
    {
      "src": "/images/icons/android-chrome-192x192-883114367f2d72fc9a509409454a1e73.png",
      "sizes": "192x192",
      "type":"image/png"
    },
    {
      "src": "/images/icons/android-chrome-512x512-af3d768ff652dc2be589a3c22c6dc827.png",
      "sizes": "512x512",
      "type": "image/png"
    }
  ]
}

and the following browserconfig.xml file

<?xml version="1.0"?>
<browserconfig>
  <msapplication>
    <tile>
      <square150x150logo src="/images/icons/mstile-150x150.png"/>
      <TileColor>#ffffff</TileColor>
    </tile>
  </msapplication>
</browserconfig>

Configuration

Disable

You can disable the addon by adding a configuration option to ember-cli-build.js build file.

var EmberApp = require('ember-cli/lib/broccoli/ember-app');

module.exports = function(defaults) {
  var options = {
    'ember-web-app': {
      enabled: false
    }
  };

  var app = new EmberApp(defaults, options);

  return app.toTree();
};

Fingerprint

You can add fingerprint checksum to your manifest.webmanifest file by configuring broccoli-asset-rev.

The following example prepends with a custom domain and adds fingerprint checksum to the manifest.webmanifest file.

ember-cli-build.js

var EmberApp = require('ember-cli/lib/broccoli/ember-app');
var broccoliAssetRevDefaults = require( 'broccoli-asset-rev/lib/default-options' );

module.exports = function(defaults) {
  var options = {
    fingerprint: {
      extensions: broccoliAssetRevDefaults.extensions.concat(['webmanifest']),
      prepend: 'https://www.example.com/'
    }
  };

  var app = new EmberApp(defaults, options);

  return app.toTree();
};

Note that the replaceExtensions configuration from broccoli-asset-rev is updated internally by ember-web-app so you don't have to configure yourself on your project.

API documentation

This Ember addon generates a Web Application Manifest at build time using the config/manifest.js configuration file.

It also generates some compatibility meta tags for supporting vendor specific web application features like Apple's Web Content For Safari and Microsoft's Browser configuration schema that don't yet support the Web Application Manifest standard.

Internally, this addon takes into account four different types of targets for generating the web app manifest taking care of including some backward compatibility meta tags in order to support as many devices and browsers as possible. These targets are:

  • manifest (default target)
  • apple (to target iOS devices)
  • ms (to target Win8/Win10 devices)
  • android (to target options specific for android devices)

Not all targets are used for all properties (actually, most properties are not affected by the targets).

Generating Icons

ember-web-app doesn't generate icons or images. If you want to automate the generation of icons starting from a master image, you can install ember-cli-image-transformer.

Managing all the various icon sizes and types can be overwhelming. One solution is to start with a base image which can be use to generate the necessary icon permutations for your environment. You can use ember-cli-image-transformer to handle this task.

If your manifest.js looks like this and needs a 192px and a 512px icon:

// config/manifest.js
export default function() {
  return {
    icons: [
      {
        src: '/assets/icons/appicon-32.png',
        sizes: `32x32`,
        targets: ['favicon']
      },
      ...[192, 280, 512].map((size) => ({
        src: `/assets/icons/appicon-${size}.png`,
        sizes: `${size}x${size}`
      }))
    ]
  };
}

You can start with a base brand-icon.svg image and automatically build the 192x192 and 512x512 versions by installing ember-cli-image-transformer and adding the necessary configuration to your ember-cli-build.js file:

// ember-cli-build.js
module.exports = function(defaults) {
  var app = new EmberApp(defaults, {
    'ember-cli-image-transformer': {
      images: [
        {
          inputFilename: 'lib/images/brand-icon.svg',
          outputFileName: 'appicon-',
          convertTo: 'png',
          destination: 'assets/icons/',
          sizes: [32, 192, 280, 512]
        }
      ]
    }
  });
