🚀 GitHub Actions & Automated CI/CD

NOTE

GitHub Actions turns your repository into a complete automation engine capable of building, testing, linting, auditing security, and deploying software directly in response to any Git lifecycle event.

🏛️ 1. GitHub Actions Architecture

graph TD
    Event["⚡ Event / Trigger<br/><i>(push, pull_request, schedule, workflow_dispatch)</i>"] --> Workflow["📜 Workflow (.github/workflows/*.yml)"]
    Workflow --> Job1["🏗️ Job 1: Lint & TypeCheck (ubuntu-latest)"]
    Workflow --> Job2["🧪 Job 2: Test Matrix (Node 18, 20, 22)"]
    Job1 --> Step1["Step: Checkout"]
    Job1 --> Step2["Step: Setup Node"]
    Job1 --> Step3["Step: Run Scripts"]
    Job2 --> Job3["🚀 Job 3: Deploy to GitHub Pages (needs: [Job1, Job2])"]

Core Concepts:

1. Workflows: Declarative YAML configuration files in .github/workflows/.
2. Events (Triggers): Events that kick off a workflow run (push, pull_request, workflow_dispatch, release, schedule).
3. Jobs: Sets of steps executed on the same runner machine. Jobs run concurrently by default.
4. Runners: Virtual machine environments hosted by GitHub (ubuntu-latest, windows-latest, macos-latest) or self-hosted.
5. Steps & Actions: Individual shell tasks (run: ...) or packaged community actions (uses: actions/checkout@v4).

🌐 2. Production Workflow: Deploy Quartz to GitHub Pages

This repository uses the following battle-tested workflow in .github/workflows/deploy-gh-pages.yaml:

name: Deploy to GitHub Pages
 
on:
  push:
    branches:
      - main
  workflow_dispatch:
 
permissions:
  contents: read
  pages: write
  id-token: write
 
concurrency:
  group: "pages"
  cancel-in-progress: true
 
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Repository
        uses: actions/checkout@v4
        with:
          fetch-depth: 0
 
      - name: Setup Node.js 22
        uses: actions/setup-node@v4
        with:
          node-version: 22
 
      - name: Install Dependencies
        run: npm ci
 
      - name: Install Quartz Plugins
        run: npx quartz plugin install
 
      - name: Build Quartz
        run: npx quartz build
 
      - name: Configure GitHub Pages
        uses: actions/configure-pages@v4
 
      - name: Upload Artifact
        uses: actions/upload-pages-artifact@v3
        with:
          path: public
 
  deploy:
    environment:
      name: github-pages
      url: ${{ steps.deployment.outputs.page_url }}
    runs-on: ubuntu-latest
    needs: build
    steps:
      - name: Deploy to GitHub Pages
        id: deployment
        uses: actions/deploy-pages@v4
