# Expo Sharing

A library that provides implementing sharing files.
Android, iOS, Web, Included in Expo Go

> For the complete documentation index, see [llms.txt](/llms.txt). Use this file to discover all available pages.

`expo-sharing` allows you to share files directly with other compatible applications.

#### Sharing limitations on web

-   `expo-sharing` for web is built on top of the Web Share API, which still has [very limited browser support](https://caniuse.com/#feat=web-share). Be sure to check that the API can be used before calling it by using `Sharing.isAvailableAsync()`.
-   **HTTPS required on web**: The Web Share API is only available on web when the page is served over https. Run your app with `npx expo start --tunnel` to enable it.
-   **No local file sharing on web**: Sharing local files by URI works on Android and iOS, but not on web. You cannot share local files on web by URI — you will need to upload them somewhere and share that URI.

#### Sharing to your app from other apps

Currently `expo-sharing` only supports sharing _from your app to other apps_ and you cannot register to your app to have content shared to it through the native share dialog on native platforms. You can read more [in the related feature request](https://expo.canny.io/feature-requests/p/share-extension-ios-share-intent-android). You can setup this functionality manually in Xcode and Android Studio and create an [Expo Config Plugin](/config-plugins/introduction) to continue using [Expo Prebuild](/workflow/continuous-native-generation).

## Installation

```sh
npx expo install expo-sharing
```

If you are installing this in an [existing React Native app](/bare/overview), make sure to [install `expo`](/bare/installing-expo-modules) in your project.

## API

```js
import * as Sharing from 'expo-sharing';
```

## Methods
