Set up fullstack project

Use the Angular CLI to bootstrap a new Angular app:

npx -p @angular/cli ng new amplify-app

? Which stylesheet format would you like to use? CSS
? Do you want to enable Server-Side Rendering (SSR) and Static Site Generation (SSG/Pre-rendering)? No

This is create your angular app in a folder amplify-app. Use the following command to switch into that folder:

cd amplify-app

Initialize a new backend

Now that you have a running app, it's time to set up Amplify so that you can create the necessary backend services needed to support the app.

Open a new terminal. From the root of the project, run:

amplify init

When you initialize Amplify you'll be prompted for some information about the app:

For newer versions of Angular, you will have to change the Distribution Directory Path from dist to dist/amplify-app/browser to match how Angular will build your project.

? Enter a name for the project: amplifyapp
The following configuration will be applied:

Project information
| Name: amplifyapp
| Environment: dev
| Default editor: Visual Studio Code
| App type: javascript
| Javascript framework: angular
| Source Directory Path: src
| Distribution Directory Path: dist/amplify-app/browser
| Build Command: npm run-script build
| Start Command: ng serve

? Initialize the project with the above configuration? Yes
Using default provider  awscloudformation
? Select the authentication method you want to use: AWS profile

For more information on AWS Profiles, see:
https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-profiles.html

? Please choose the profile you want to use: default

When you initialize a new Amplify project, a few things happen:

• It creates a top level directory called amplify that stores your backend definition. During the tutorial you'll add cloud capabilities, such as GraphQL API and web hosting. As you add these features, the amplify folder will grow with infrastructure-as-code templates that define your backend stack. Infrastructure-as-code is a best practice way to create a replicable backend stack.
• It creates a file called amplifyconfiguration.json in your designated Source Directory Path that holds all the configuration for the services you create with Amplify. This is how the Amplify JavaScript client library is able to get the necessary information to connect to your backend services.
• It modifies the .gitignore file, adding some generated files to the ignore list

Install Amplify Libraries

The aws-amplify package is the main library for working with Amplify Libraries in your projects:

npm install aws-amplify

Set up frontend

Next, configure the Amplify libraries client-side so it can interact with backend services.

Open main.ts and add the following code below the last import:

import { Amplify } from 'aws-amplify';
import amplifyconfig from './amplifyconfiguration.json';
Amplify.configure(amplifyconfig);

In order to import amplifyconfiguration.json files in Typescript, you may need to modify your tsconfig.json and enable resolveJsonModule and allowSyntheticDefaultImports in the case that strict mode is enabled.

{
  ...
  "compilerOptions": {
    "allowSyntheticDefaultImports": true,
    "resolveJsonModule": true,
    ...
  }
}

And that's all it takes to configure Amplify. As you add or remove categories and make updates to your backend configuration using the Amplify CLI, the configuration in amplifyconfiguration.json will update automatically.

Now that your app is set up and Amplify is initialized, you can add an API in the next step.
