rexMaps

A personal CalTopo-style mapping app for hiking and trail running: stackable map layers with opacity/reorder controls, route planning with snap-to-trail routing, and saved maps — running on Cloudflare Workers for ~$0/mo.

Start here: docs/PLAN.md (staged roadmap + decision log) and docs/LAYERS.md (every tile source, with endpoints and terms). Agent guidance lives in AGENTS.md.

Develop

npm run dev        # Next.js dev server (http://localhost:3000)
npm run preview    # build + run in the Workers runtime locally
npm run deploy     # build + deploy to Cloudflare Workers

Optional: copy .env.example → .env.local and set a Google Map Tiles API key to enable the Google Satellite / Google Maps layers. Everything else works keyless.
