Quick Start

npm install
npm run dev

Data

CPI series are pulled from FRED at build time by scripts/fetch-fred-data.mjs and written to static/data/. The prebuild script runs it automatically; run it manually with npm run fetch-data.

• With a FRED_API_KEY (see .env.example) it uses the FRED API; without one it falls back to the public fredgraph.csv endpoint (throttled).
• Countries and series IDs are defined in scripts/fred-registry.mjs.

Scripts

• npm run dev — dev server (fetches data if missing)
• npm run build — production build (refetches data)
• npm run fetch-data — refresh static/data/
• npm run deploy — build and publish to GitHub Pages
• npm run check / npm run lint / npm run format
