Introduction

Angular is a development platform for building WEB, mobile and desktop applications using HTML, CSS and TypeScript (JavaScript). Currently, Angular is at version 13 and Google is the main maintainer of the project.

GitHub is a source code and file storage service with version control using git tool. GitHub Actions is a service to automate the software workflow.

Amazon S3 (Simple Storage Service) is an object storage service offering scalability, data availability, security and performance.

Prerequisites

• git
• Node.js and npm
• Angular CLI
• IDE (e.g. Visual Studio Code)

2. Click on the option Root user, fill in the field Root user email address and click on the button Next.

Note:

• If you don't have an Amazon account, do steps 1 to 9 of the post Authentication using the Amazon Cognito to an Angular application in the session Create and configure the account on the Amazon Cognito.

6. Let's create and configure the file with the GitHub Actions flow. Create the .github/workflows/gh-pages.yml file.

mkdir -p .github/workflows
touch .github/workflows/gh-pages.yml

7. Configure the .github/workflows/gh-pages.yml file with the content below.

name: GitHub Pages

on:
  push:
    branches:
    - main

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
    - name: Configure AWS Credentials
      uses: aws-actions/configure-aws-credentials@v1
      with:
        aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
        aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
        aws-region: sa-east-1

    - name: Checkout
      uses: actions/checkout@v2

    - name: Setup Node.js
      uses: actions/setup-node@v2
      with:
        node-version: 14

    - name: Install dependencies
      run: npm install

    - name: Run tests
      run: npm run test:headless

    - name: Build
      run: npm run build:prod

    - name: Deploy
      if: success()
      run: aws s3 sync ./dist/angular-github-actions-amazon-s3 s3://angular-github-actions-amazon-s3

Notes:

• The aws-access-key-id and aws-secret-access-key settings were done in the GitHub repository.
• The aws-region setting is the bucket region.
• The ./dist/angular-github-actions-amazon-s3 setting is the application build folder.
• The s3://angular-github-actions-amazon-s3 setting is the bucket name.

8. Syncronize the application on the GitHub repository that was created.

9. Ready! After synchronizing the application on the GitHub repository, the GitHub Actions build the application and synchronize with Amazon S3 bucket. Access the URL http://angular-github-actions-amazon-s3.s3-website-sa-east-1.amazonaws.com/ and check if the application is working. Replace the URL values with your bucket name and region.

Validate the run of the GitHub Actions flow

1. Let's validate the run of the GitHub Actions flow. Access the repository https://github.com/rodrigokamada/angular-github-actions-amazon-s3 created and click on the link Actions.

2. Click on the flow runned.

3. Click on the job deploy.

4. Click on each step to validate the run.

5. Ready! We validate the run of the GitHub Actions flow.

The application repository is available at https://github.com/rodrigokamada/angular-github-actions-amazon-s3.
