React Native Photo Manipulator Getting Started Guide

1. Add react-native-photo-manipulator to your dependencies.

$ yarn add react-native-photo-manipulator

(or)

$ npm install react-native-photo-manipulator

2. Link native modules.

From react-native 0.60 autolinking will take care of the link step but don't forget to run pod install. So you can skip to next section.

For react-native 0.59.x and below. React Native modules that include native Objective-C, Swift, Java, or Kotlin code have to be "linked" so that the compiler knows to include them in the app.

Automatic installation

$ react-native link react-native-photo-manipulator

NOTE: If you ever need to uninstall React Native Photo Manipulator, run react-native unlink react-native-photo-manipulator to unlink it.
