Hosting an Angular application on GitHub Pages using GitHub Actions

Introduction

Angular is a development platform for building WEB, mobile and desktop applications using HTML, CSS and TypeScript (JavaScript). Currently, Angular is at version 12 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 Pages is a static file hosting service using a public repository. GitHub Actions is a service to automate the software workflow.

Prerequisites

Before you start, you need to install and configure the tools:

Getting started

Create and configure the account on the GitHub

1. Let's create the account. Access the site https://github.com/ and click on the button Sign up.

5. Fill in the field Repository name and click on the button Create repository.

GitHub - Create repository

6. Ready! Account created and repository https://github.com/rodrigokamada/angular-github-actions created.

GitHub - Repository created

Create the Angular application

1. Let's create the application with the Angular base structure using the @angular/cli with the route file and the SCSS style format.

ng new angular-github-actions
? Would you like to add Angular routing? Yes
? Which stylesheet format would you like to use? SCSS   [ https://sass-lang.com/documentation/syntax#scss                ]

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
Enter fullscreen mode Exit fullscreen mode

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: Checkout
      uses: actions/checkout@v2

    - name: Setup Node.js
      uses: actions/setup-node@v2
      with:
        node-version: '16'

    - 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()

      with:
        github_token: ${{ secrets.GITHUB_TOKEN }}
        publish_dir: dist/angular-github-actions
        enable_jekyll: true
Enter fullscreen mode Exit fullscreen mode

Note:

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

GitHub - Repository

9. Ready! After synchronizing the application on the GitHub repository, the GitHub Actions build the application and synchronize on the branch gh-pages. Access the URL https://rodrigokamada.github.io/angular-github-actions/ and check if the application is working. Replace the rodrigokamada value with your GitHub username.
