Configuration

Configuration Options

Option	Platform	Type	Description
splashImage	Both	string	Path to the splash image file.
backgroundColor	Android	string	Background color in HEX format (e.g., #ffffff).

To configure the splash helper, add a section to your react-native.config.js file:

module.exports = {
  dependencies: {},
  '@sekizlipenguen/react-native-splash-helper': {
    android: {
      splashImage: './assets/splash_image.png' // Path to your splash image
    },
    ios: {
      splashImage: './assets/splash_image.png'  // Path to your splash image
    }
  }
};

---

Usage

Run the following command to generate the splash screens:

npx @sekizlipenguen/react-native-splash-helper generate-splash

What It Does

This library handles the splash screen during the app's loading phase:

• iOS: Manages the Launch Screen Storyboard until the app is fully loaded.
• Android: Manages the Splash Activity and its configuration until React Native initializes.

Once the app has fully loaded and transitions to the App.js, the splash screen is no longer managed by this library. At this point, you can create and display custom screens or animations within your React Native app.

1. Android:

   • Updates styles.xml to include the android:windowBackground property for detected themes.
   • Updates or creates colors.xml with the specified background color.
   • Generates the drawable resource for the splash screen.
   • Updates the AndroidManifest.xml to ensure consistency in theme configuration.

2. iOS:

   • Updates the LaunchScreen.storyboard file with the splash image and background color.
   • Creates the necessary image assets in the Images.xcassets directory.

Example

• Updates the following in styles.xml:

  <style name="AppTheme" parent="Theme.AppCompat.DayNight.NoActionBar">
      <item name="android:windowBackground">@drawable/splash_background</item>
  </style>

• Updates or creates colors.xml:

  <resources>
      <color name="splash_background">#ffffff</color>
  </resources>

• Creates splash_background.xml in drawable:

  <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
      <item android:drawable="@color/splash_background" />
      <item>
          <bitmap android:gravity="fill" android:src="@drawable/splash_image" />
      </item>
  </layer-list>

iOS Output

  <document type="com.apple.InterfaceBuilder3.CocoaTouch.Storyboard.XIB" ...>
      <scene>
          ...
          <view key="view" contentMode="scaleToFill">
              <color key="backgroundColor" systemColor="systemBackgroundColor" />
              <subviews>
                  <imageView contentMode="scaleAspectFill" image="splash_image" ... />

Splash Screen Example

Notes

• Make sure your splash image is available at the specified path.
• If any required file (e.g., styles.xml, colors.xml) does not exist, it will be created automatically.
• The script is non-destructive and will not overwrite existing configurations unless necessary.
