Mobile Configuration

If your Meteor application targets mobile platforms such as iOS or Android, you can configure your app's metadata and build process in a special top-level file called mobile-config.js which is not included in your application and is used only for this configuration.

The code snippet below is an example mobile-config.js file. The rest of this section will explain the specific API commands in greater detail.

// This section sets up some basic app metadata, the entire section is optional.
App.info({
  id: 'com.example.matt.uber',
  name: 'über',
  description: 'Get über power in one button click',
  author: 'Matt Development Group',
  email: 'contact@example.com',
  website: 'http://example.com'
});

// Set up resources such as icons and launch screens.
App.icons({
  'iphone_2x': 'icons/icon-60@2x.png',
  'iphone_3x': 'icons/icon-60@3x.png',
  // More screen sizes and platforms...
});

// Before Meteor 2.6 we had to pass device specific splash screens for iOS, but this behavior was dropped in favor of story board images.
App.launchScreens({
    // iOS
    // For most cases you will only need to use the 'ios_universal' and 'ios_universal_3x'.
    'ios_universal': { src: 'splash/Default@2x.png', srcDarkMode: 'splash/Default@2x~dark.png' }, // (2732x2732) - All @2x devices, if device/mode specific is not declared
    'ios_universal_3x': 'splash/Default@3x.png', // (2208x2208) - All @3x devices, if device/mode specific is not declared

    // If you still want to use a universal splash, but want to fine-tune for the device mode (landscape, portrait), then use the following keys:
    'Default@2x~universal~comany': 'splash/Default@2x~universal~comany.png', // (1278x2732) - All @2x devices in portrait mode.
    'Default@2x~universal~comcom': 'splash/Default@2x~universal~comcom.png', // (1334x750) - All @2x devices in landscape (narrow) mode.
    'Default@3x~universal~anycom': 'splash/Default@3x~universal~anycom.png', // (2208x1242) - All @3x devices in landscape (wide) mode.
    'Default@3x~universal~comany': 'splash/Default@3x~universal~comany.png', // (1242x2208) - All @3x devices in portrait mode.

    // However, if you need to fine tune the splash screens for the device idiom (iPhone, iPad, etc).
    'Default@2x~iphone~anyany': 'splash/Default@2xiphoneanyany.png', // (1334x1334) - iPhone SE/6s/7/8/XR
    'Default@2x~iphone~comany': 'splash/Default@2xiphonecomany.png', // (750x1334) - iPhone SE/6s/7/8/XR - portrait mode
    'Default@2x~iphone~comcom': 'splash/Default@2xiphonecomcom.png', // (1334x750) - iPhone SE/6s/7/8/XR - landscape (narrow) mode
    'Default@3x~iphone~anyany': 'Default@3xiphoneanyany.png', // (2208x2208) - iPhone 6s Plus/7 Plus/8 Plus/X/XS/XS Max
    'Default@3x~iphone~anycom': { src: 'splash/Default@3xiphoneanycom.png', srcDarkMode: 'splash/Default@3xiphoneanycom~dark.png' }, // (2208x1242) - iPhone 6s Plus/7 Plus/8 Plus/X/XS/XS Max - landscape (wide) mode
    'Default@3x~iphone~comany': 'Default@3xiphonecomany.png', // (1242x2208) - iPhone 6s Plus/7 Plus/8 Plus/X/XS/XS Max - portrait mode
    'Default@2x~ipad~anyany': 'Default@2xipadanyany.png', // (2732x2732) - iPad Pro 12.9"/11"/10.5"/9.7"/7.9"
    'Default@2x~ipad~comany': 'Default@2xipadcomany.png', // (1278x2732) - iPad Pro 12.9"/11"/10.5"/9.7"/7.9" - portrait mode

    // Android
    'android_universal': 'splash/android_universal.png', // (320x480)
});

// Set PhoneGap/Cordova preferences.
App.setPreference('BackgroundColor', '0xff0000ff');
App.setPreference('HideKeyboardFormAccessoryBar', true);
App.setPreference('Orientation', 'default');
App.setPreference('Orientation', 'all', 'ios');

// Pass preferences for a particular PhoneGap/Cordova plugin.
App.configurePlugin('com.phonegap.plugins.facebookconnect', {
  APP_ID: '1234567890',
  API_KEY: 'supersecretapikey'
});

// Add custom tags for a particular PhoneGap/Cordova plugin to the end of the
// generated config.xml. 'Universal Links' is shown as an example here.
App.appendToConfig(`
  <universal-links>
    <host name="localhost:3000" />
  </universal-links>
`);

App.info

Summary:

Set your mobile app's core configuration information.

Arguments:

Source code

Name	Type	Description	Required
options	Object	undefined	Yes

Options:

Name	Type	Description	Required
id, version, name, description, author, email, website	String	Each of the options correspond to a key in the app's core configuration as described in the Cordova documentation.	No

const result = App.info();
  options
);

App.setPreference

Summary:

Add a preference for your build as described in the Cordova documentation.

Arguments:

Source code

Name	Type	Description	Required
name	String	A preference name supported by Cordova's config.xml.	Yes
value	String	The value for that preference.	Yes
platform	String	Optional. A platform name (either ios or android) to add a platform-specific preference.	No

const result = App.setPreference();
  "name",
  "value",
  "platform",  // this param is optional 
);

App.accessRule

Summary:

Set a new access rule based on origin domain for your app. By default your application has a limited list of servers it can contact. Use this method to extend this list.

Default access rules:

• tel:*, geo:*, mailto:*, sms:*, market:* are allowed and are handled by the system (e.g. opened in the phone app or an email client)
• http://localhost:* is used to serve the app's assets from.
• The domain or address of the Meteor server to connect to for DDP and hot code push of new versions.

Read more about domain patterns in Cordova docs.

Starting with Meteor 1.0.4 access rule for all domains and protocols (<access origin="*"/>) is no longer set by default due to certain kind of possible attacks.

Arguments:

Source code

Name	Type	Description	Required
pattern	String	The pattern defining affected domains or URLs.	Yes
options	Object	undefined	No

Options:

Name	Type	Description	Required
type	String	Possible values: 'intent': Controls which URLs the app is allowed to ask the system to open. (e.g. in the phone app or an email client). 'navigation': Controls which URLs the WebView itself can be navigated to (can also needed for iframes). 'network' or undefined: Controls which network requests (images, XHRs, etc) are allowed to be made.	No
launchExternal	Boolean	(Deprecated, use type: 'intent' instead.)	No

const result = App.accessRule();
  "pattern",
  options,  // this param is optional 
);

For example this Cordova whitelist syntax:

<access origin="https://www.google-analytics.com" />
<allow-navigation href="https://example.com" />

is equivalent to:

App.accessRule('https://www.google-analytics.com');
App.accessRule('https://example.com', { type: 'navigation' });

App.configurePlugin

Summary:

Set the build-time configuration for a Cordova plugin.

Arguments:

Source code

config	Object	A set of key-value pairs which will be passed at build-time to configure the specified plugin.	Yes

const result = App.configurePlugin();
  "id",
  config,
);

Note: When using App.configurePlugin to re-configure a plugin which has been previously configured, the changes may not be reflected without manually clearing the existing Cordova build. To clear the existing Cordova build, remove the .meteor/local/cordova-build directory and re-build the application using either meteor run or meteor build.
