# Installation in managed Expo projects

For [managed](https://docs.expo.dev/archive/managed-vs-bare/) Expo projects, please follow the installation instructions in the [API documentation for the latest stable release](https://docs.expo.dev/versions/latest/sdk/background-fetch/).

# Installation in bare React Native projects

For bare React Native projects, you must ensure that you have [installed and configured the `expo` package](https://docs.expo.dev/bare/installing-expo-modules/) before continuing.

### Add the package to your npm dependencies

```
npx expo install expo-background-fetch
```

### Configure for iOS

Run `npx pod-install` after installing the npm package.

In order to use `BackgroundFetch` API in standalone, detached and bare apps on iOS, your app has to include background mode in the `Info.plist` file. See [background tasks configuration guide](https://docs.expo.dev/versions/latest/sdk/task-manager/#configuration-for-standalone-apps) for more details.

### Configure for Android

No additional set up necessary.

This module might listen when the device is starting up. It's necessary to continue working on tasks started with `startOnBoot`. It also keeps devices "awake" that are going idle and asleep fast, to improve reliability of the tasks.
