A library that provides implementing sharing files.
GitHub
npm
expo-sharing
allows you to share files directly with other compatible applications.
expo-sharing
for web is built on top of the Web Share API, which still has very limited browser support. Be sure to check that the API can be used before calling it by using Sharing.isAvailableAsync()
.npx expo start --https
to enable it.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. You can setup this functionality manually in Xcode and Android Studio and create an Expo Config Plugin to continue using Expo Prebuild.
