GitHub Actions &
GitHub Pages デプロイガイド

リポジトリのルートに .github/workflows/pages.yml を作成します。ビルド不要な静的ファイルそのままをデプロイする場合に最適です。

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: false

jobs:
  deploy:
    environment:
      name: github-pages
      url: ${{ steps.deployment.outputs.page_url }}
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4

      - name: Setup Pages
        uses: actions/configure-pages@v5

      - name: Upload artifact
        uses: actions/upload-pages-artifact@v3
        with:
          path: '.'

      - name: Deploy to GitHub Pages
        id: deployment
        uses: actions/deploy-pages@v4

ビルドステップが必要なプロジェクト向け。npm run build で生成された ./dist や ./build などをデプロイします。

• Settings > Pages > Source を GitHub Actions に変更
• permissions に pages: write と id-token: write を記述
• upload-pages-artifact の path がビルド成果物のディレクトリを指しているか確認
• カスタムドメインを使う場合は CNAME ファイルをデプロイ対象ディレクトリに含める
