Support

version react-native version
3.0.0+ 0.63.0+
2.0.0+ 0.60.0+

For 0.59-, you should use jetify -r

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.

πŸ†˜ Manual linking

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:

πŸ‘€ See manual linking instructions

iOS

Add this line to your ios/Podfile file, then run pod install.

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

Android

  1. 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')
  1. Add the implementation line to the dependencies in android/app/build.gradle:
dependencies {
  // ...
  implementation project(':react-native-bootsplash')
}
  1. 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 {

  // …

  @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:

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

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

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

assets/bootsplash_logo@1,5x.png
assets/bootsplash_logo@2x.png
assets/bootsplash_logo@3x.png
assets/bootsplash_logo@4x.png

iOS

⚠️ Only .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
{
  // …
  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

Android

  1. 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 {

  // …

  @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.

  1. 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>
  1. Edit the 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/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">
      <!-- ⚠️ add android:exported="true" and android:launchMode="singleTask" above -->
      <!-- remove the <intent-filter> from .MainActivity -->
    </activity>

    <!-- add the following lines (use the theme you created at step 2) -->
    <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>
    </activity>

    <!-- … -->

  </application>

</manifest>

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 });
      console.log("Bootsplash has been hidden successfully");
    });
  }, []);

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

πŸ€™ A more complex example is available in the /example folder.

Handle deep linking (on Android)

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="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/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">
      <!-- ⚠️ 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>

    <!-- … -->

  </application>

</manifest>

Testing with Jest

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"]
}

Using 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>
  );
}

πŸ•΅οΈβ€β™‚οΈ 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!).
