gulp-mobile-icons

Gulp plugin that creates PNG icons for iOS and Android based on a SVG image.

Please read this blog post for a detailed explanation of the problem that the plugin solves.

Usage

To use the the plugin in your gulp process:

const gulp = require('gulp');
const mobileIcons = require('gulp-mobile-icons');

gulp.task('default', [], function() {
    gulp.src('icon.svg')
        .pipe(mobileIcons())
        .pipe(gulp.dest('images'));
});

This will create all icons in the folder images/.

If you want to customize the filenames or sizes of the icons, pass an object to mobileIcons(MY_SIZES):

gulp.task('build_icons', [], function() {
    const MY_SIZES = {
        'icon-57': { width: 57, height: 57 },
        'icon-57@2x': { width: 114, height: 114 },
        'icon-72': { width: 72, height: 72 }
    }
    gulp.src('icon.svg')
        .pipe(mobileIcons(MY_SIZES))
        .pipe(gulp.dest('images'));
});

Cordova / PhoneGap

Add the following to your config.xml to use the icons in a Cordova/PhoneGap application:

    <icon src="images/android-xxxhdpi.png" density="xxxhdpi"/>
</platform>

Web application

When using the app as a web application, you need to add to your index.html (see also Apple documentation):

<!-- iPhone -->
<link rel="apple-touch-icon" href="images/[e-mail]">
<!-- iPhone retina -->
<link rel="apple-touch-icon" sizes="180x180" href="images/[e-mail]">
<!-- iPad -->
<link rel="apple-touch-icon" sizes="152x152" href="images/images/[e-mail]">
<!-- iPad retina -->
<link rel="apple-touch-icon" sizes="167x167" href="images/[e-mail]">
<!-- Chrome -->
<link rel="icon" sizes="192x192" href="images/chrome-192.png">
<link rel="icon" sizes="128x128" href="images/chrome-128.png">
