Haze Watch SG

A single-page Singapore haze and weather monitor: a national PSI overview, an interactive five-zone NEA map (North / South / East / West / Central), and an ASEAN city comparison (Jakarta, Kuala Lumpur, Bangkok, Manila, Hanoi), split across a Haze and a Weather tab.

All figures on the page are illustrative sample data, shaped like the real NEA (data.gov.sg) PSI/PM2.5 feed and the Open-Meteo forecast API, for preview purposes — not a live feed.

Deploy

This is a static site with no build step: index.html is the entire app.

npm i -g vercel   # if you don't already have it
vercel            # deploy a preview
vercel --prod     # deploy to production

Vercel will auto-detect this as a static project. vercel.json sets clean URLs and a couple of baseline security headers; no build command or output directory is required.

Local preview

Open index.html directly in a browser, or serve it locally:

npx serve .
