Resource Generator
This tool will crop and resize JPEG and PNG source images to generate images for modern iOS and Android devices. It will also register the generated images in config.xml
so that Cordova projects are updated accordingly.
Install
$ npm install -g cordova-res
Usage
cordova-res
must run at the root of a Cordova project, such as:
resources/
├── icon.png
└── splash.png
config.xml
resources/icon.png
must be at least 1024×1024pxresources/splash.png
must be at least 2732×2732px
To generate resources with all the default options, just run:
$ cordova-res
cordova-res
accepts a platform for the first argument. If specified, resources are generated only for that platform:
$ cordova-res ios
Otherwise, cordova-res
looks for platforms in config.xml
(e.g. <platform name="ios">
) and generates resources only for them.
Documentation
See the help documentation on the command line with the --help
flag.
$ cordova-res --help
Adaptive Icons
Android Adaptive Icons are also supported. If you choose to use them, create the following additional file(s):
resources/android/icon-foreground.png
must be at least 432×432pxresources/android/icon-background.png
must be at least 432×432px
A color may also be used for the icon background by specifying the --icon-background-source
option with a hex color code, e.g. --icon-background-source '#FFFFFF'
.
Regular Android icons will still be generated as a fallback for Android devices that do not support adaptive icons.
:memo: Note: Cordova 9+ and cordova-android
8+ is required.
Tips
.gitignore
To avoid committing large generated images to your repository, you can add the
following lines to your .gitignore
:
resources/android/icon
resources/android/splash
resources/ios/icon
resources/ios/splash
resources/windows/icon
resources/windows/splash
Programmatic API
cordova-res
can be used programmatically.
CommonJS Example
const run = require('cordova-res');
await run();
TypeScript Example
run()
takes an options object described by the interface Options
. If options are provided, resources are generated in an explicit, opt-in manner. In the following example, only Android icons and iOS splash screens are generated.
import { Options, run } from 'cordova-res';
const options: Options = {
directory: '/path/to/project',
resourcesDirectory: 'resources',
logstream: process.stdout, // Any WritableStream
platforms: {
android: { icon: { sources: ['resources/icon.png'] } },
ios: { splash: { sources: ['resources/splash.png'] } },
},
};
await run(options);
