Development

The app uses a native module, so it runs in a development build, not in Expo Go.

bun install
bunx expo run:ios       # or: bunx expo run:android

Typecheck with bunx tsc --noEmit.

Station catalog

src/data/stations-de.json and the logos in assets/logos/de are generated from a curated list (scripts/stations/curated.json) and radio-browser.info. Every stream is checked before it goes in.

node scripts/stations/build.mjs   # refresh catalog, check streams, normalize logos
node scripts/gen-logos.mjs        # regenerate src/data/logos.generated.ts

A station is missing or broken? Open an issue or a pull request against curated.json.

Releases
