• Output: build directory
• Dev Port: 3000

Setup

1. Clone the Template

git clone --depth 1 https://github.com/Eng0AI/happiness-dashboard-template.git .

If the directory is not empty:

git clone --depth 1 https://github.com/Eng0AI/happiness-dashboard-template.git _temp_template
mv _temp_template/* _temp_template/.* . 2>/dev/null || true
rm -rf _temp_template

2. Remove Git History (Optional)

rm -rf .git
git init

3. Install Dependencies

pnpm install

4. Process Data Sources

pnpm run sources

Build

pnpm run build

Generates static site in build/ directory.

Deploy

Vercel (Recommended)

vercel pull --yes -t $VERCEL_TOKEN
vercel build --prod -t $VERCEL_TOKEN
vercel deploy --prebuilt --prod --yes -t $VERCEL_TOKEN

Important: Deploy from project root, not build/ directory.

Netlify

netlify deploy --prod --dir=build

Data Sources

CSV files in sources/happiness_score/:

• hs2024.csv – Current year happiness data
• hsArchive.csv – Historical happiness data

Notes

• Use pnpm (not npm) – .npmrc has shamefully-hoist=true for Evidence compatibility
• Build locally – Vercel/Netlify build can timeout due to DuckDB compilation (40+ min)
• Uses CSV files, no database setup needed
• Never run pnpm run dev in VM environment
