A library that provides access to controlling the visibility behavior of native splash screen.
The SplashScreen
module from the expo-splash-screen
library is used to tell the splash screen to remain visible until it has been explicitly told to hide. This is useful to do tasks that will happen behind the scenes such as making API calls, pre-loading fonts, animating the splash screen and so on.
Also, see the guide on creating a splash screen image, or quickly generate an icon and splash screen using your browser.
-
npx expo install expo-splash-screen
If you are installing this in an existing React Native app, start by installing expo
in your project. Then, follow the additional instructions as mentioned by the library's README under "Installation in bare React Native projects" section.
This example shows how to keep the splash screen visible while loading app resources and then hide the splash screen when the app has rendered some initial content.
import { useCallback, useEffect, useState } from 'react';
import { Text, View } from 'react-native';
import Entypo from '@expo/vector-icons/Entypo';
import * as SplashScreen from 'expo-splash-screen';
import * as Font from 'expo-font';
// Keep the splash screen visible while we fetch resources
SplashScreen.preventAutoHideAsync();
// Set the animation options. This is optional.
SplashScreen.setOptions({
duration: 1000,
fade: true,
});
export default function App() {
const [appIsReady, setAppIsReady] = useState(false);
useEffect(() => {
async function prepare() {
try {
// Pre-load fonts, make any API calls you need to do here
await Font.loadAsync(Entypo.font);
// Artificially delay for two seconds to simulate a slow loading
// experience. Please remove this if you copy and paste the code!
await new Promise(resolve => setTimeout(resolve, 2000));
} catch (e) {
console.warn(e);
} finally {
// Tell the application to render
setAppIsReady(true);
}
}
prepare();
}, []);
const onLayoutRootView = useCallback(() => {
if (appIsReady) {
// This tells the splash screen to hide immediately! If we call this after
// `setAppIsReady`, then we may see a blank screen while the app is
// loading its initial state and rendering its first pixels. So instead,
// we hide the splash screen once we know the root view has already
// performed layout.
SplashScreen.hide();
}
}, [appIsReady]);
if (!appIsReady) {
return null;
}
return (
<View
style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}
onLayout={onLayoutRootView}>
<Text>SplashScreen Demo! 👋</Text>
<Entypo name="rocket" size={30} />
</View>
);
}
You can configure expo-splash-screen
using its built-in config plugin if you use config plugins in your project (EAS Build or npx expo run:[android|ios]
). The plugin allows you to configure various properties that cannot be set at runtime and require building a new app binary to take effect. If your app does not use EAS Build, then you'll need to manually configure the package.
Using the config plugin, as shown below, is the recommended method for configuring the splash screen. The other methods are now considered legacy and will be removed in the future.

Name | Default | Description |
---|---|---|
backgroundColor | #ffffff | A hex color string representing the background color of the splash screen. |
image | undefined | The path to the image file that will be displayed on the splash screen. This should be your app icon or logo. |
enableFullScreenImage_legacy | false | Only for: iOS Enabling this property allows using a full screen image as the splashscreen. This is to help with the transition from the legacy splash screen configuration and will be removed in the future. |
dark | undefined | An object containing properties for configuring the splash screen when the device is in dark mode. |
imageWidth | 100 | The width to make the image. |
android | undefined | An object containing properties for configuring the splash screen on Android. |
ios | undefined | An object containing properties for configuring the splash screen on iOS. |
You can also configure expo-splash-screen
, using the following app config properties but the config plugin should be preferred.
See how to configure the native projects in the installation instructions in the expo-splash-screen
repository.
SplashScreen
provides an out-of-the-box fade animation. It can be configured using the setOptions
method.
SplashScreen.setOptions({
duration: 1000,
fade: true,
});
If you prefer to use custom animation, see the with-splash-screen
example on how to apply any arbitrary animations to your splash screen. You can initialize a new project from this example by running npx create-react-native-app -t with-splash-screen
.
import * as SplashScreen from 'expo-splash-screen';
Hides the native splash screen immediately. Be careful to ensure that your app has content ready to display when you hide the splash screen, or you may see a blank screen briefly. See the "Usage" section for an example.
void
Makes the native splash screen (configured in app.json
) remain visible until hideAsync
is called.
Important note: It is recommended to call this in global scope without awaiting, rather than inside React components or hooks, because otherwise this might be called too late, when the splash screen is already hidden.
Promise<boolean>
Example
import * as SplashScreen from 'expo-splash-screen';
SplashScreen.preventAutoHideAsync();
export default function App() {
// ...

Configures the splashscreens default animation behavior.
