Support

Installation

$ 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.

🆘 Manual linking

Because this package targets React Native 0.65.0+, you probably don't need to link it manually. But if you have a special case, follow these additional instructions:

target 'YourAwesomeProject' do
  # …
  pod 'RNBootSplash', :path => '../node_modules/react-native-bootsplash'
end

include ':react-native-bootsplash'
project(':react-native-bootsplash').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-bootsplash/android')

dependencies {
  // ...
  implementation project(':react-native-bootsplash')
}

import com.zoontek.rnbootsplash.RNBootSplashPackage; // ⬅️ add the RNBootSplashPackage import

public class MainApplication extends Application implements ReactApplication {

  // …

  @Override
  protected List<ReactPackage> getPackages() {
    @SuppressWarnings("UnnecessaryLocalVariable")
    List<ReactPackage> packages = new PackageList(this).getPackages();
    // …
    packages.add(new RNBootSplashPackage());
    return packages;
  }

  // …
}

Setup

Assets generation

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 ✨.

$ npx react-native generate-bootsplash --help
# --- or ---
$ yarn react-native generate-bootsplash --help

The command can take multiple arguments:

yarn react-native generate-bootsplash <logoPath>

Generate a launch screen using an original logo file (PNG or SVG)

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 recommend 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")
  --platforms <platforms>     platforms to generate assets for (comma separated) (default: "android,ios")
  -h, --help                  output usage information

Full command usage example

yarn react-native generate-bootsplash assets/bootsplash_logo_original.png \
  --background-color=F5FCFF \
  --logo-width=100 \
  --assets-path=assets \
  --flavor=main \
  --platforms=android,ios

This tool relies on the naming conventions that are used in the /example project and will therefore create the following files:

# Only if --assets-path was specified
assets/bootsplash_logo.png
assets/bootsplash_logo@1,5x.png
assets/bootsplash_logo@2x.png
assets/bootsplash_logo@3x.png
assets/bootsplash_logo@4x.png

iOS

ℹ️ For react-native < 0.71 setup, follow the v4.4.0 README.md.

Edit the ios/YourProjectName/AppDelegate.mm file:

#import "AppDelegate.h"
#import "RNBootSplash.h" // ⬅️ add the header import

// …

@implementation AppDelegate

// …

// ⬇️ Add this before file @end
- (UIView *)createRootViewWithBridge:(RCTBridge *)bridge
                          moduleName:(NSString *)moduleName
                           initProps:(NSDictionary *)initProps {
  UIView *rootView = [super createRootViewWithBridge:bridge
                                          moduleName:moduleName
                                           initProps:initProps];

  [RNBootSplash initWithStoryboard:@"BootSplash" rootView:rootView]; // ⬅️ initialize the splash screen

  return rootView;
}

@end

Set the BootSplash.storyboard as launch screen file:

Drag and drop the file	Create folder reference	Set as Launch Screen File

Android

⚠️  On Android >= 12, the splash screen will not appear if you start your app from the terminal / Android Studio. To see it, kill your app and restart it in normal conditions (tap on your app icon in the app launcher).

1. Edit your android/app/build.gradle file:

dependencies {
  // …

  implementation("androidx.swiperefreshlayout:swiperefreshlayout:1.0.0")
  implementation("androidx.core:core-splashscreen:1.0.0") // add this line

  // …

⚠️  Don't forget going into the android directory to execute a ./gradlew clean && ./gradlew build (or perform a Gradle sync in Android Studio).

2. Edit your android/app/src/main/res/values/styles.xml file:

<resources>

  <style name="AppTheme" parent="Theme.AppCompat.DayNight.NoActionBar">
      <!-- Your base theme customization -->
  </style>

  <!-- BootTheme should inherit from Theme.SplashScreen -->
  <style name="BootTheme" parent="Theme.SplashScreen">
    <item name="windowSplashScreenBackground">@color/bootsplash_background</item>
    <item name="windowSplashScreenAnimatedIcon">@mipmap/bootsplash_logo</item>
    <item name="postSplashScreenTheme">@style/AppTheme</item>
  </style>

</resources>

3. Edit your android/app/src/main/AndroidManifest.xml file:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.rnbootsplashexample">

  <!-- … -->

  <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/BootTheme"> <!-- Replace @style/AppTheme with @style/BootTheme -->
    <!-- … -->
  </application>
</manifest>

4. Finally edit your android/app/src/main/java/com/yourprojectname/MainActivity.java file:

// …

// add these required imports:
import android.os.Bundle;
import com.zoontek.rnbootsplash.RNBootSplash;

public class MainActivity extends ReactActivity {

  // …

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    RNBootSplash.init(this); // ⬅️ initialize the splash screen
    super.onCreate(savedInstanceState); // or super.onCreate(null) with react-native-screens
  }
}

API

hide()

Method type

type hide = (config?: { fade?: boolean; duration?: number }) => Promise<void>;

Note: Only durations above 220ms are visually noticeable. Smaller values will be ignored and the default duration will be used.

Usage

import RNBootSplash from "react-native-bootsplash";

RNBootSplash.hide(); // immediate
RNBootSplash.hide({ fade: true }); // fade with 220ms default duration
RNBootSplash.hide({ fade: true, duration: 500 }); // fade with custom duration

getVisibilityStatus()

Method type

type VisibilityStatus = "visible" | "hidden" | "transitioning";
type getVisibilityStatus = () => Promise<VisibilityStatus>;

Usage

import RNBootSplash from "react-native-bootsplash";

RNBootSplash.getVisibilityStatus().then((status) => console.log(status));

Real world example

import React, { useEffect } from "react";
import { Text } from "react-native";
import RNBootSplash from "react-native-bootsplash";

function App() {
  useEffect(() => {
    const init = async () => {
      // …do multiple sync or async tasks
    };

    init().finally(async () => {
      await RNBootSplash.hide({ fade: true, duration: 500 });
      console.log("BootSplash has been hidden successfully");
    });
  }, []);

  return <Text>My awesome app</Text>;
}

🤙 A more complex example is available in the /example folder.

With React Navigation

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>
  );
}

With react-native-bars

In order to keep fully transparent status and navigation bars on Android once the splash screen is hidden (and control them), this library play nicely with react-native-bars. Check its README for more informations.

Testing with Jest

Testing code which uses this library requires 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(),
    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"]
}

🕵️‍♂️ 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.
• Hiding the launch screen is configurable: fade it out or hide it without any animation.
