## Support
This library follows the React Native [releases support policy](https://github.com/reactwg/react-native-releases/blob/main/docs/support.md).
It is supporting the **latest version**, and the **two previous minor series**.
## Installation
```bash
$ 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`._
## Setup
### Assets generation
In order to speed up the setup, we provide a **CLI** to generate assets, update config files, create the Android Drawable XML file and the iOS Storyboard file automatically ✨.
```bash
$ npx react-native-bootsplash generate --help
# --- or ---
$ yarn react-native-bootsplash generate --help
```
The command can take multiple arguments:
```bash
Usage: react-native-bootsplash generate [options]
Generate a launch screen using a logo file path (PNG or SVG)
Arguments:
logo Logo file path (PNG or SVG)
Options:
--platforms Platforms to generate for, separated by a comma (default: "android,ios,web")
--background Background color (in hexadecimal format) (default: "#fff")
--logo-width Logo width at @1x (in dp - we recommend approximately ~100) (default: 100)
--assets-output Assets output directory path (default: "assets/bootsplash")
--flavor Android flavor build variant (where your resource directory is) (default: "main")
--html HTML template file path (your web app entry point) (default: "public/index.html")
--plist Custom Info.plist file path
--license-key License key to enable brand and dark mode assets generation
--brand Brand file path (PNG or SVG)
--brand-width Brand width at @1x (in dp - we recommend approximately ~80) (default: 80)
--dark-background [dark mode] Background color (in hexadecimal format)
--dark-logo [dark mode] Logo file path (PNG or SVG)
--dark-brand [dark mode] Brand file path (PNG or SVG)
-h, --help display help for command
```
#### 💪 Unlock the CLI full potential
In order to use the `--brand`, `--brand-width` and `--dark-*` options, you must specify a `--license-key`.
With it, the generator is able to output over **50 files** (logo and brand images generated in all pixel densities, dark mode versions, etc.), saving you (and your company!) a massive amount of time not only at creation, but also at each adjustment ⏱️
_📍 This license key grants unlimited and unrestricted usage of the generator for the buyer's purposes (meaning you can execute the assets generation as much as you want)._
#### Full command usage example
```bash
# Without license key
yarn react-native-bootsplash generate svgs/light-logo.svg \
--platforms=android,ios,web \
--background=F5FCFF \
--logo-width=100 \
--assets-output=assets/bootsplash \
--flavor=main \
--html=public/index.html
# With license key 🔑
yarn react-native-bootsplash generate svgs/light-logo.svg \
--platforms=android,ios,web \
--background=F5FCFF \
--logo-width=100 \
--assets-output=assets/bootsplash \
--flavor=main \
--html=public/index.html \
--license-key=xxxxx \
--brand=svgs/light-brand.svg \
--brand-width=80 \
--dark-background=00090A \
--dark-logo=svgs/dark-logo.svg \
--dark-brand=svgs/dark-brand.svg
```
### With Expo
1. First, uninstall `expo-splash-screen`:
```bash
$ npm uninstall expo-splash-screen
# --- or ---
$ yarn remove expo-splash-screen
```
```diff
{
"expo": {
"plugins": [
- [
- "expo-splash-screen",
- {
- "image": "./assets/images/splash-icon.png",
- "imageWidth": 200,
- "resizeMode": "contain",
- "backgroundColor": "#ffffff"
- }
- ],
]
}
}
```
2. Add the plugin in your app config (_if you have a license key, pass it via the `BOOTSPLASH_LICENSE_KEY` environment variable_):
Dynamic configuration (app.config.js, app.config.ts)
```ts
import type { ConfigContext, ExpoConfig } from "expo/config";
import bootsplash from "react-native-bootsplash/expo"; // use `require` in app.config.js
export default ({ config }: ConfigContext): ExpoConfig => ({
// …
platforms: ["android", "ios", "web"], // must be explicit
plugins: [
bootsplash({
logo: "./assets/logo.png",
logoWidth: 100,
background: "#f5fcff",
// …
}),
],
});
```
Static configuration (app.json)
```jsonc
{
"expo": {
// …
"platforms": ["android", "ios", "web"], // must be explicit
"plugins": [
[
"react-native-bootsplash",
{
"logo": "./assets/logo.png",
"logoWidth": 100,
"background": "#f5fcff",
// …
},
],
],
},
}
```
_📌 The available plugins options are:_
```ts
type PluginOptions = {
android?: {
darkContentBarsStyle?: boolean; // Enforce system bars style (default: undefined)
};
logo: string; // Logo file path (PNG or SVG) - required
background?: string; // Background color (in hexadecimal format) (default: "#fff")
logoWidth?: number; // Logo width at @1x (in dp - we recommend approximately ~100) (default: 100)
assetsOutput?: string; // Assets output directory path (default: "assets/bootsplash")
// Addon options
brand?: string; // Brand file path (PNG or SVG)
brandWidth?: number; // Brand width at @1x (in dp - we recommend approximately ~80) (default: 80)
darkBackground?: string; // [dark mode] Background color (in hexadecimal format)
darkLogo?: string; // [dark mode] Logo file path (PNG or SVG)
darkBrand?: string; // [dark mode] Brand file path (PNG or SVG)
};
```
### With bare React Native
#### iOS
Edit your `ios/YourApp/AppDelegate.swift` file:
```swift
import ReactAppDependencyProvider
import RNBootSplash // ⬅️ add this import
// …
class ReactNativeDelegate: RCTDefaultReactNativeFactoryDelegate {
// …
// ⬇️ override this method
override func customize(_ rootView: RCTRootView) {
super.customize(rootView)
RNBootSplash.initWithStoryboard("BootSplash", rootView: rootView) // ⬅️ initialize the splash screen
}
}
```

super.onCreate(savedInstanceState)
}
}
```
With react-native-screens >= v4.16.0
```kotlin
// ⬇️ add these required imports
import android.os.Bundle
import com.swmansion.rnscreens.fragment.restoration.RNScreensFragmentFactory

super.onCreate(null)
}
}
```
_ℹ️ Refer to [previous package documentation](https://github.com/zoontek/react-native-bootsplash/tree/6.3.12?tab=readme-ov-file#with-bare-react-native) for setup steps with React Native < 0.80._
## API
### hide()
Hide the splash screen (immediately, or with a fade out).
#### Method type
```ts
type hide = (config?: { fade?: boolean }) => Promise;
```
#### Usage
```tsx
import { useEffect } from "react";
import { Text } from "react-native";
import BootSplash from "react-native-bootsplash";
const App = () => {
useEffect(() => {
const init = async () => {
// …do multiple sync or async tasks
};
init().finally(async () => {
await BootSplash.hide({ fade: true });
console.log("BootSplash has been hidden successfully");
});
}, []);
return My awesome app;
};
```
### isVisible()
Return the current visibility status of the native splash screen.
#### Method type
```ts
type isVisible = () => boolean;
```
#### Usage
```ts
import BootSplash from "react-native-bootsplash";
if (BootSplash.isVisible()) {
// Do something
}
```
### useHideAnimation()
A hook to easily create a custom hide animation by animating all splash screen elements using `Animated`, `react-native-reanimated` or else (similar as the video on top of this documentation).
#### Method type
```ts
type useHideAnimation = (config: {
ready?: boolean; // a boolean flag to delay the animate execution (default: true)
// the required generated assets
manifest: Manifest; // the manifest file is generated in your assets directory
logo?: ImageRequireSource;
darkLogo?: ImageRequireSource;
brand?: ImageRequireSource;
darkBrand?: ImageRequireSource;
// specify if you are using translucent status / navigation bars
// in order to avoid a shift between the native and JS splash screen
statusBarTranslucent?: boolean;
navigationBarTranslucent?: boolean;
animate: () => void;
}) => {
container: ContainerProps;
logo: LogoProps;
brand: BrandProps;
};
```
#### Usage
```tsx
import { useState } from "react";
import { Animated, Image } from "react-native";
import BootSplash from "react-native-bootsplash";
type Props = {
onAnimationEnd: () => void;
};
const AnimatedBootSplash = ({ onAnimationEnd }: Props) => {
const [opacity] = useState(() => new Animated.Value(1));
const { container, logo /*, brand */ } = BootSplash.useHideAnimation({
manifest: require("../assets/bootsplash/manifest.json"),
logo: require("../assets/bootsplash/logo.png"),
// darkLogo: require("../assets/bootsplash/dark-logo.png"),
// brand: require("../assets/bootsplash/brand.png"),
// darkBrand: require("../assets/bootsplash/dark-brand.png"),
animate: () => {
// Perform animations and call onAnimationEnd
Animated.timing(opacity, {
useNativeDriver: true,
toValue: 0,
duration: 500,
}).start(() => {
onAnimationEnd();
});
},
});
return (
{/* */}
);
};
const App = () => {
const [visible, setVisible] = useState(true);
return (
{/* content */}
{visible && (
{
setVisible(false);
}}
/>
)}
);
};
```
**This example is simple for documentation purpose (we only animate the container).**
**🤙 A more complex example is available in the [`/example` folder](./example/src/AnimatedBootSplash.tsx).**
## FAQ
### How can I enforce the splash screen system bar colors?
By default, the system bars uses `dark-content` in light mode and `light-content` in dark mode. To enforce a specific value, edit your `values/styles.xml` file:
```xml
```
### Why are both light and dark assets inlined in my index.html?
For the sake of simplicity. Since the light and dark versions of your assets are likely identical (except for the colors), if your `index.html` file is compressed with **gzip**, the size difference will be negligible.
### How should I use it 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.
```tsx
import { NavigationContainer } from "@react-navigation/native";
import BootSplash from "react-native-bootsplash";
const App = () => (
{
BootSplash.hide();
}}
>
{/* content */}
);
```
### How can I mock the module in my tests?
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:
```ts
jest.mock("react-native-bootsplash", () => {
return {
hide: jest.fn().mockResolvedValue(),
isVisible: jest.fn(),
useHideAnimation: jest.fn().mockReturnValue({
container: {},
logo: { source: 0 },
brand: { source: 0 },
}),
};
});
```
After that, we need to add the setup file in the jest config. You can add it under [setupFiles](https://jestjs.io/docs/en/configuration.html#setupfiles-array) option in your jest config file:
```json
{
"setupFiles": ["/jest/setup.js"]
}
```
