Announcing the AWS Amplify CLI toolchain. Click here to read more.

Angular & Ionic

AWS Amplify helps developers to create high-quality Ionic apps quickly by handling the heavy lifting of configuring and integrating cloud services behind the scenes. It also provides a powerful high-level API and ready-to-use security best practices.


AWS Amplify provides Angular Components that you can use with Ionic in aws-amplify-angular npm package.

Install aws-amplify and aws-amplify-angular npm packages into your Angular app.

$ npm install --save aws-amplify
$ npm install --save aws-amplify-angular
$ npm install --save ionic-angular

Setup the AWS Backend

To configure your Ionic app for AWS Amplify, you need to create a backend configuration with Amplify CLI and import the auto-generated configuration file into your project.

Following commands will enable Auth category and will create aws-exports.js configuration file under your projects /src folder.

$ npm install -g @aws-amplify/cli
$ amplify init
$ amplify add auth
$ amplify add storage
$ amplify push # Updates your backend

Please visit Authentication Guide and Storage Guide to learn more about enabling these categories.

A configuration file is placed inside your configured source directory. To import the configuration file to your Ionic app, you will need to rename aws-exports.js to aws-exports.ts. You can setup your package.json npm scripts to rename the file for you, so that any configuration changes which result in a new generated aws-exports.js file get changed over to the .ts extension.

"scripts": {	
    "start": "[ -f src/aws-exports.js ] && mv src/aws-exports.js src/aws-exports.ts || ng serve; ng serve",	
    "build": "[ -f src/aws-exports.js ] && mv src/aws-exports.js src/aws-exports.ts || ng build --prod; ng build --prod"	

Import and Configure Amplify

Import the configuration file and configure Amplify in your main.ts file.

import Amplify from 'aws-amplify';
import amplify from './aws-exports';

In your home page component src/app/app.module.ts, you can import Amplify modules as following:

import { AmplifyAngularModule, AmplifyService } from 'aws-amplify-angular';

  imports: [
  providers: [

NOTE: the service provider is optional. You can import the core categories normally i.e. import { Analytic } from 'aws-amplify' or create your own provider. The service provider does some work for you and exposes the categories as methods. The provider also manages and dispatches authentication state changes using observables which you can subscribe to within your components (see below).

Using the AWS Amplify API

AmplifyService is a provider in your Angular app, and it provides AWS Amplify core categories through dependency injection. To use AmplifyService with dependency injection, inject it into the constructor of any component or service, anywhere in your application.

import { AmplifyService } from 'aws-amplify-angular';

    public navCtrl:NavController,
    public amplifyService: AmplifyService,
    public modalCtrl: ModalController
) {
    this.amplifyService = amplifyService;

You can access and work directly with AWS Amplify Categories via the built-in service provider:

import { Component } from '@angular/core';
import { AmplifyService }  from 'aws-amplify-angular';

  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']

export class AppComponent {
  constructor( public amplify:AmplifyService ) {
      this.amplifyService = amplify;
      /** now you can access category APIs:
       * this.amplifyService.auth();          // AWS Amplify Auth
       *;     // AWS Amplify Analytics
       *;       // AWS Amplify Storage
       * this.amplifyService.api();           // AWS Amplify API
       * this.amplifyService.cache();         // AWS Amplify Cache
       * this.amplifyService.pubsub();        // AWS Amplify PubSub
       * this.amplifyService.interactions();  // AWS Amplify Interactions

You can access all AWS Amplify Category APIs with AmplifyService.

Subscribe to Authentication State Changes

Import AmplifyService into your component and listen for auth state changes:

import { AmplifyService }  from 'aws-amplify-angular';

  // ...
constructor( public amplifyService: AmplifyService ) {

    this.amplifyService = amplifyService;

        .subscribe(authState => {
            this.signedIn = authState.state === 'signedIn';
            if (!authState.user) {
                this.user = null;
            } else {
                this.user = authState.user;
                this.greeting = "Hello " + this.user.username;


Use View Components

AWS Amplifies provides components that you can use in your Angular view templates.


The Authenticator component creates an out-of-the-box signing/sign-up experience for your Angular app.

Before using this component, please be sure that you have activated Authentication category:

$ amplify add auth

To use Authenticator, just add the amplify-authenticator directive in your .html view:

  <amplify-authenticator framework="Ionic"></amplify-authenticator>

Photo Picker

Photo Picker component will render a file upload control that will allow choosing a local image and uploading it to Amazon S3. Once an image is selected, a base64 encoded image preview will be displayed automatically.

Before using this component, please be sure that you have activated user-files with Amplify CLI:

$ amplify add storage

To render photo picker in an Angular view, use amplify-photo-picker component:

<amplify-photo-picker framework="Ionic"

The component will emit two events:

  • (picked) - Emitted when an image is selected. The event will contain the File object which can be used for upload.
  • (loaded) - Emitted when an image preview has been rendered and displayed.
  • path - An optional S3 image path (prefix).
  • storageOptions - An object passed within the ‘options’ property in the Storage.put request. This can be used to set the permissions ‘level’ property of the objects being uploaded i.e. ‘private’, ‘protected’, or ‘public’.

Learn more about S3 permissions..

S3 Album

S3 Album component display a list of images from the connected S3 bucket.

Before using this component, please be sure that you have activated user-files with Amplify CLI:

$ amplify add storage

To render the album, use amplify-s3-album component in your Angular view:

<amplify-s3-album framework="Ionic" 
    path="pics" (selected)="onAlbumImageSelected($event)">
  • options - object which is passed as the ‘options’ parameter to the .get request. This can be used to set the ‘level’ of the objects being requested (i.e. ‘protected’, ‘private’, or ‘public’
  • (selected) event can be used to retrieve the URL of the clicked image on the list:
onAlbumImageSelected( event ) { event, '_blank' );


The amplify-interactions component provides you with a Chatbot user interface. You can pass it three parameters:

  1. bot: The name of the Amazon Lex Chatbot

  2. clearComplete: A flag indicating whether or not the messages should be cleared at the end of the conversation.

  3. complete: A function that is executed when the conversation is completed.

<amplify-interactions bot="yourBotName" clearComplete="true" (complete)="onBotComplete($event)"></amplify-interactions>

See the Interactions documentation for information on creating an Amazon Lex Chatbot.


Sumerian Scene

The amplify-sumerian-scene component provides you with a prebuilt UI for loading and displaying Amazon Sumerian scenes inside of your website:

Note: The UI component will inherit the height and width of the direct parent DOM element. Make sure to set the width and height styling on the parent DOM element to your desired size.

// sceneName: the configured friendly scene you would like to load
<amplify-sumerian-scene sceneName="scene1" framework="Ionic"></amplify-sumerian-scene>

See the XR documentation for information on creating and publishing a Sumerian scene.


To use the aws-amplify-angular components you will need to install ‘@aws-amplify/ui’.

Add the following to your styles.css file to use the default styles: @import '~aws-amplify-angular/theme.css';

You can use custom styling for AWS Amplify components. Just import your custom styles.css that overrides the default styles which can be found in /node_modules/aws-amplify-angular/theme.css.

Angular 6 Support

Currently, the newest version of Angular (6.x) does not provide the shim for the global object, which was provided in previous versions. Specific AWS Amplify dependencies rely on this shim. While we evaluate the best path forward to address this issue, you have a couple of options for re-creating the shim in your Angular 6 app to make it compatible with Amplify.

  1. Add the following to your polyfills.ts: (window as any).global = window;.

  2. Add the following script to your index.html <head> tag:

        if (global === undefined) {
            var global = window;
