Getting started

Each app is independent. cd into the app folder and run:

npm install
npm start

CI/CD

Each app has its own GitHub Actions workflow that triggers only when files in that app change.

Vercel deployment

Each app is deployed as a separate Vercel project with a different Root Directory:

• Portfolio (gateway): apps/portfolio -- owns the custom domain, rewrites to other apps
• Spreadsheet: apps/spreadsheet
• Spreadsheet API: apps/spreadsheet-api
