๐ react-native-bootsplash
Show a splash screen during app startup. Hide it when you are ready.
For migration from the v3, check the MIGRATION.md
guide.
Support
This library follows the React Native releases support policy.
It is supporting the latest version, and the two previous minor series.
Installation
$ npm install --save react-native-bootsplash
# --- or ---
$ yarn add react-native-bootsplash
ios
directory to execute a pod install
.
๐ Manual linking
Because this package targets recent React Native versions, you probably don't need to link it manually. But if you have a special case, follow these additional instructions:
๐ See manual linking instructions
iOS
Add this line to your ios/Podfile
file, then run pod install
.
target 'YourAwesomeProject' do
# โฆ
pod 'RNBootSplash', :path => '../node_modules/react-native-bootsplash'
end
Android
- 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; // โฌ
๏ธ add the RNBootSplashPackage import
public class MainApplication extends Application implements ReactApplication {
// โฆ
@Override
protected List<ReactPackage> getPackages() {
@SuppressWarnings("UnnecessaryLocalVariable")
List<ReactPackage> packages = new PackageList(this).getPackages();
// โฆ
packages.add(new RNBootSplashPackage());
return packages;
}
// โฆ
}
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/[email protected]

.
Edit the ios/YourProjectName/AppDelegate.mm
file:

#import "RNBootSplash.h" // โฌ
๏ธ add the header import

Android
- Edit your
android/app/build.gradle
file:
dependencies {
// The version of react-native is set by the React Native Gradle Plugin
implementation("com.facebook.react:react-android")
implementation("androidx.core:core-splashscreen:1.0.0") // add this line
// โฆ

directory to execute a ./gradlew clean && ./gradlew build
(or perform a Gradle sync in Android Studio).
- 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">

- Edit your
android/app/src/main/AndroidManifest.xml

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

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 () => {
// โฆdo 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>;
}
/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"]
}
