A sample web app made using Contentful and AWS Amplify. Data lives in Contentful, code lives with GitHub and backend lives in AWS.

• Authentication with Amazon Cognito
• CMS with Contentful
• Analytics with Amazon Pinpoint
• Hosting with Amazon Amplify console
• Removing / Deleting Services

To deploy this project, you'll need the following:

• AWS account
• Contentful
• Node JS
• Amplify CLI

Clone/Fork repository.

• git clone https://github.com/syumaK/amplify-contentful-app.git

Install dependencies.

• yarn install

OR

Create a new project using the Create React App CLI.

npx create-react-app amplify-contentful-app

Now change into the new app directory & install the AWS Amplify & AWS Amplify React libraries:

cd amplify-contentful-app

yarn add aws-amplify @aws-amplify/ui-react

# NPM
$ npm install -g @aws-amplify/cli

# cURL (Mac & Linux)
curl -sL https://aws-amplify.github.io/amplify-cli/install | bash && $SHELL

# cURL (Windows)
curl -sL https://aws-amplify.github.io/amplify-cli/install-win -o install.cmd && install.cmd

Now we need to configure the CLI with our credentials.

If you'd like to see a video walkthrough of this configuration process, click here.

$ amplify configure

- Specify the AWS Region: us-east-1 || us-west-2 || eu-central-1
- Specify the username of the new IAM user: amplify-cli-user
> In the AWS Console, click Next: Permissions, Next: Tags, Next: Review, & Create User to create the new IAM user. Then return to the command line & press Enter.
- Enter the access key of the newly created user:   
? accessKeyId: (<YOUR_ACCESS_KEY_ID>)  
? secretAccessKey: (<YOUR_SECRET_ACCESS_KEY>)
- Profile Name: amplify-cli-user

We’ll use the AWS Amplify CLI to initialize backend components such as authentication to support our app:

amplify init

- ? Enter a name for the project: foodblogamplifycontentful

The following configuration will be applied:
    
- Name: foodblogamplifycontentful 
- Environment: dev
- Default editor: Visual Studio Code
- App type : javascript
- Javascript framework: react
- Source Directory Path: src
- Distribution Directory Path: build
- Build Command: npm run-script build
- Start Command: npm run-script start

- ? Initialize the project with the above configuration? (Y/n)
Using default provider  awscloudformation
- ? Select the authorization method you want to use: (use arrow keys)
> AWS profile
> AWS access keys

The Amplify init command CLI initializes a new project & you will see a new folder: amplify & a new file called aws-exports.js in the root directory. These files hold your project configuration.

To view the status of the amplify project at any time, you can run the Amplify status command:

$ amplify status

To add authentication to our web application, we can use the following command:

$ amplify add auth

? Do you want to use default authentication and security configuration? (Use arrow keys) 
> Default configuration
> Default configuration with Social Provider (Federation)
> Manual configuration
> I want to learn more.

Now, we'll run the push command and the cloud resources will be created in our AWS account.

amplify push

✔ Successfully pulled backend environment dev from the cloud.

Current Environment: dev

| Category | Resource name    | Operation | Provider plugin   |
| -------- | ---------------- | --------- | ----------------- |
| Auth     | foodblog9a5f7e3a | Create    | awscloudformation |
? Are you sure you want to continue? Yes

Now, our resources are created & we can start using them!

The first thing we need to do is to configure our React application to be aware of our new AWS Amplify project. We can do this by referencing the auto-generated aws-exports.js file that is now in our src folder.

To configure the app, open src/App.js and add the following code below the last import:

/*
import amplify modules
*/

import Amplify from 'aws-amplify'
import config from './aws-exports'
Amplify.configure(config)

Now, our app is ready to start using our AWS services.

To add authentication, we'll go into src/App.js and first import the withAuthenticator HOC (Higher Order Component) from @aws-amplify/ui-react:

// src/App.js, import the withAuthenticator component
import { withAuthenticator } from '@aws-amplify/ui-react'

Next, we'll wrap our default export (the App component) with the withAuthenticator HOC:

function App() {/* existing code here, no changes */}

/* src/App.js, change the default export to this: */
export default withAuthenticator(App)

Next test it out in your browser:

yarn start

Now, we can run the app and see that an Authentication flow has been added in front of our App component. This flow gives users the ability to sign up & sign in.

Once you sign up, check your email to confirm the sign up.

Now that you have the authentication service created, you can view it any time in the console by running the following command:

amplify console auth

> Choose User Pool

You can also easily add a preconfigured UI component for signing out.

import { withAuthenticator, AmplifySignOut } from '@aws-amplify/ui-react';

/* Somewhere in the UI */
<AmplifySignOut />

First install Contentful package

yarn add contentful

To connect to contentful and render your contents, we need the following :

• import contentful package and useState, useEffect from React as shown below:

import React, { useState, useEffect } from 'react';

/*
import contentful modules
*/

import * as contentful from 'contentful'

• initialize the contentful client as shown below:

export const client = contentful.createClient({
    space: 'XX_XXXX_XXXXXX',
    accessToken: 'XX_XXXX_XXXXXX'
});

This repo currently uses an existing Contentful space. If you'd like to replace this space with your own, so you can modify the content, you're welcome to do so.

To add analytics, we can use the following command:

amplify add analytics

Next, we'll be prompted for the following:

? Provide your pinpoint resource name: amplifyanalytics
? Apps need authorization to send analytics events. Do you want to allow guest/unauthenticated users to send analytics events (recommended when getting started)? Y
? overwrite YOURFILEPATH-cloudformation-template.yml Y

Now that the service has been created we can now begin recording events.

To record custom analytics events we need the following :

• import the Analytics class from Amplify as shown below:

import Amplify, { Analytics } from 'aws-amplify'

• invoke Analytics.recordas shown below:

  // Button for events
  function submitEvents (){
    
    Analytics.record({
      name:'userVisit',
      attributes: { name : 'Stefan', location: 'Berlin'}
    });
    
    Analytics.record({
      name:'siteVisit',
      attributes: { name : 'webinar', month: 'Nov'}
    });
  }

<button onClick={this.recordEvent}>Record Event</button>

You've successfully built a React.js web app using Amplify and Contentful! Now it's time to deploy it to the web using AWS Amplify's CI/CD and hosting service!

From the root of your project, run the following command:

amplify add hosting

? Choose Hosting with Amplify Console (Managed hosting with custom domains, Continuous deployment)
? Choose a type - Continuous deployment (Git-based deployments)
? Continuous deployment is configured in the Amplify Console. Please hit enter once you connect your repository

The Amplify Console opens and displays your deployed backend environment.

Choose the Frontend environments tab, select a Git provider, then choose Connect Branch.

After your site is successfully deployed, you'll see four green checkmarks. To view the live site, click on the automatically generated URL circled in red in the following screenshot.

👏 Congratulations, your app is online!

If at any time, or at the end of this workshop, you would like to delete a service from your project & your account, you can do this by running the amplify remove command:

amplify remove auth

amplify push

If you are unsure of what services you have enabled at any time, you can run the amplify status command:

amplify status

amplify status will give you the list of resources that are currently enabled in your app.
