    This option uses vercel build and vercel deploy --prebuilt.

    Set it to true when you build on the GitHub Actions side and deploy that data to Vercel.

    Caution

    It will not work unless the software required for building, such as Node.js, is installed correctly.

    Usage example

    name: Vercel
    
    on:
      push:
        branches: [main]
      pull_request:
    
    concurrency:
      group: ${{ github.workflow }}-${{ github.ref }}
      cancel-in-progress: true
    
    jobs:
      deploy:
        name: Deploy
        runs-on: ubuntu-latest
        permissions:
          contents: read
          deployments: write
          statuses: write
          pull-requests: write
    
        steps:
          - uses: actions/checkout@v7
    
          - uses: nexterias/actions-vercel@v2
            with:
              token: ${{ secrets.VERCEL_TOKEN }}
              org-id: ${{ secrets.VERCEL_ORG_ID }}
              project-id: ${{ secrets.VERCEL_PROJECT_ID }}
              production: ${{ github.ref == 'refs/heads/main' }}
              prebuilt: true // [!code ++]
