Show a bootsplash during app startup. Hide it when you are ready.
version | react-native version |
---|---|
3.0.0+ | 0.63.0+ |
2.0.0+ | 0.60.0+ |
For 0.59-, you should use jetify -r
$ npm install --save react-native-bootsplash
# --- or ---
$ yarn add react-native-bootsplash
Don't forget going into the ios
directory to execute a pod install
.
Because this package targets React Native 0.60.0+, you will probably don't need to link it manually. Otherwise if it's not the case, follow this additional instructions:
π See manual linking instructions
Add this line to your ios/Podfile
file, then run pod install
.
target 'YourAwesomeProject' do
# β¦
pod 'RNBootSplash', :path => '../node_modules/react-native-bootsplash'
end
- Add the following lines to
android/settings.gradle
:
include ':react-native-bootsplash'
project(':react-native-bootsplash').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-bootsplash/android')
- Add the implementation line to the dependencies in
android/app/build.gradle
:
dependencies {
// ...
implementation project(':react-native-bootsplash')
}
- Add the import and link the package in
MainApplication.java
:
import com.zoontek.rnbootsplash.RNBootSplashPackage; // <- add the RNBootSplashPackage import
public class MainApplication extends Application implements ReactApplication {
// β¦
@Override
protected List<ReactPackage> getPackages() {
@SuppressWarnings("UnnecessaryLocalVariable")
List<ReactPackage> packages = new PackageList(this).getPackages();
// β¦
packages.add(new RNBootSplashPackage());
return packages;
}
// β¦
}
In order to speed up the setup, we provide a CLI to generate assets, create the Android Drawable XML file and the iOS Storyboard file automatically β¨.
$ npx react-native generate-bootsplash --help
# --- or ---
$ yarn react-native generate-bootsplash --help
The command can take multiple arguments:
react-native generate-bootsplash <logoPath>
Generate a launch screen using an original logo file
Options:
--background-color <color> color used as launch screen background (in hexadecimal format) (default: "#fff")
--logo-width <width> logo width at @1x (in dp - we recommand approximately ~100) (default: 100)
--assets-path [path] path to your static assets directory (useful to require the logo file in JS)
--flavor <flavor> [android only] flavor build variant (outputs in an android resource directory other than "main")
-h, --help output usage information
yarn react-native generate-bootsplash assets/bootsplash_logo_original.png \
--background-color=F5FCFF \
--logo-width=100 \
--assets-path=assets \
--flavor=main
This tool relies on the naming conventions that are used in the /example
project and will therefore create the following files:
android/app/src/main/res/drawable/bootsplash.xml
android/app/src/main/res/values/colors.xml (creation and edition)
android/app/src/main/res/mipmap-hdpi/bootsplash_logo.png
android/app/src/main/res/mipmap-mdpi/bootsplash_logo.png
android/app/src/main/res/mipmap-xhdpi/bootsplash_logo.png
android/app/src/main/res/mipmap-xxhdpi/bootsplash_logo.png
android/app/src/main/res/mipmap-xxxhdpi/bootsplash_logo.png

.storyboard
files are supported (Apple has deprecated other methods in April 2020).
Edit the ios/YourProjectName/AppDelegate.m
file:
#import "AppDelegate.h"
#import <React/RCTBridge.h>
#import <React/RCTBundleURLProvider.h>
#import <React/RCTRootView.h>
#import "RNBootSplash.h" // <- add the header import
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// β¦
rootViewController.view = rootView;
self.window.rootViewController = rootViewController;
[self.window makeKeyAndVisible];
[RNBootSplash initWithStoryboard:@"BootSplash" rootView:rootView]; // <- initialization using the storyboard file name
return YES;
}
Set the BootSplash.storyboard
as launch screen file:
Drag and drop the file | Create folder reference | Set as Launch Screen File |
---|---|---|
![]() |
![]() |
![]() |
- Edit the
android/app/src/main/java/com/yourprojectname/MainActivity.java
file:
import android.os.Bundle; // <- add this necessary import
import com.facebook.react.ReactActivity;
import com.zoontek.rnbootsplash.RNBootSplash; // <- add this necessary import
public class MainActivity extends ReactActivity {
// β¦
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
RNBootSplash.init(R.drawable.bootsplash, MainActivity.this); // <- display the generated bootsplash.xml drawable over our MainActivity
}
As Android will not create our main activity before launching the app, we need to display a different activity at start, then switch to our main one.
- Edit the
android/app/src/main/res/values/styles.xml
file:
<resources>
<!-- Base application theme -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Your base theme customization -->
</style>
<!-- Add the following lines (BootTheme should inherit from AppTheme) -->
<style name="BootTheme" parent="AppTheme">
<!-- set the generated bootsplash.xml drawable as activity background -->
<item name="android:background">@drawable/bootsplash</item>
</style>
</resources>
- Edit the
android/app/src/main/AndroidManifest.xml
file:
<manifest xmlns:android="https://schemas.android.com/apk/res/android"
package="com.rnbootsplashexample">
<!-- β¦ -->
<application
android:name=".MainApplication"
android:label="@string/app_name"

If you want to correctly handle deep linking with this package, you should edit the android/app/src/main/AndroidManifest.xml
file like this:
<manifest xmlns:android="https://schemas.android.com/apk/res/android"
package="com.rnbootsplashexample">
<!-- β¦ -->
<application
android:name=".MainApplication"
android:label="@string/app_name"
android:icon="@mipmap/ic_launcher"
android:roundIcon="@mipmap/ic_launcher_round"
android:allowBackup="false"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize|uiMode"
android:label="@string/app_name"
android:windowSoftInputMode="adjustResize"
android:exported="true"
android:launchMode="singleTask">
<!-- β οΈ add android:exported="true" and android:launchMode="singleTask" above -->
<!-- remove the <intent-filter> from .MainActivity -->
</activity>
<activity
android:name="com.zoontek.rnbootsplash.RNBootSplashActivity"
android:theme="@style/BootTheme"
android:launchMode="singleTask">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<!-- add your deep linking instructions inside the RNBootSplashActivity declaration -->
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="YOUR APP SCHEME" /> <!-- replace this with your custom scheme -->
</intent-filter>
</activity>
<!-- β¦ -->
</application>
</manifest>
Testing code which uses this library required some setup since we need to mock the native methods.
To add the mocks, create a file jest/setup.js (or any other file name) containing the following code:
jest.mock("react-native-bootsplash", () => {
return {
hide: jest.fn().mockResolvedValueOnce(),
show: jest.fn().mockResolvedValueOnce(),
getVisibilityStatus: jest.fn().mockResolvedValue("hidden"),
};
});
After that, we need to add the setup file in the jest config. You can add it under setupFiles option in your jest config file:
{
"setupFiles": ["<rootDir>/jest/setup.js"]
}
If you are using React Navigation, you can hide the splash screen once the navigation container and all children have finished mounting by using the onReady
function.
import React from "react";
import { NavigationContainer } from "@react-navigation/native";
import RNBootSplash from "react-native-bootsplash";
function App() {
return (
<NavigationContainer onReady={() => RNBootSplash.hide()}>
{/* content */}
</NavigationContainer>
);
}
π΅οΈββοΈ Comparison with react-native-splash-screen
-
If
react-native-splash-screen
encourages you to display an image over your application,react-native-bootsplash
way-to-go is to design your launch screen using platforms tools (Xcode layout editor and Android drawable resource). -
It should not prevent you from seeing red screen errors.
-
Hiding the launch screen is configurable: fade it out or hide it without any animation at all (no fade needed if you want to animate it out!).
