AWS Amplify is a JavaScript library for frontend and mobile developers building cloud-enabled applications

AWS Amplify provides a declarative and easy-to-use interface across different categories of cloud operations. AWS Amplify goes well with any JavaScript based frontend workflow and React Native for mobile developers.

Our default implementation works with Amazon Web Services (AWS), but AWS Amplify is designed to be open and pluggable for any custom backend or service.

Visit our Documentation site to learn more about AWS Amplify. Please see our Amplify JavaScript page within our Documentation site for information around the full list of features we support.

React Native

For React Native development, install aws-amplify:

$ npm install aws-amplify --save

If you are developing a React Native app, you can install an additional package aws-amplify-react-native containing Higher Order Components:

$ npm install aws-amplify-react-native --save

Visit our Installation Guide for React Native to start building your web app.

Notice:

Amplify 4.x.x has breaking changes for React Native. Please see the breaking changes below:

• If you are using React Native or Expo, you will need to add @react-native-async-storage/async-storage as a dependency to your application, in addition to the other React Native dependencies:

// React Native
yarn add aws-amplify amazon-cognito-identity-js @react-native-community/netinfo @react-native-async-storage/async-storage
npx pod-install

// Expo
yarn add aws-amplify @react-native-community/netinfo @react-native-async-storage/async-storage

Amplify 3.x.x has breaking changes. Please see the breaking changes below:

• AWS.credentials and AWS.config don’t exist anymore in Amplify JavaScript.
  • Both options will not be available to use in version 3. You will not be able to use and set your own credentials.
  • For more information on this change, please see the AWS SDK for JavaScript v3
• aws-sdk@2.x has been removed from Amplify@3.x.x in favor of version 3 of aws-sdk-js. We recommend to migrate to aws-sdk-js-v3 if you rely on AWS services that are not supported by Amplify, since aws-sdk-js-v3 is imported modularly.

If you can't migrate to aws-sdk-js-v3 or rely on aws-sdk@2.x, you will need to import it separately.

• If you are using exported paths within your Amplify JS application, (e.g. import from "@aws-amplify/analytics/lib/Analytics") this will now break and no longer will be supported. You will need to change to named imports:

  import { Analytics } from 'aws-amplify';

• If you are using categories as Amplify.<Category>, this will no longer work and we recommend to import the category you are needing to use:

  import { Auth } from 'aws-amplify';
