How It Works

Question data lives in 663 CSV files (data/companies/), one per company. At build time, a prebuild script parses all CSVs into a single public/data/questions.json. The dashboard fetches this JSON client-side and caches it in localStorage.

No API routes. No database. No auth. Everything is statically generated.

Development

# Install dependencies
pnpm install

# Run dev server (Turbopack)
pnpm dev

# Build for production
pnpm run prebuild   # generates public/data/questions.json from CSVs
pnpm build          # static export to out/

# Lint & format
pnpm lint
pnpm format

Deployment

pnpm run build:worker   # build for Cloudflare
pnpm run preview        # local preview with Wrangler
pnpm run deploy         # deploy to Cloudflare Pages
