RadioPlayer

RadioPlayer is a Vite + React web app for browsing, playing, and casting radio stations. It uses a managed catalog from public/stations.json, exposes a same-origin managed endpoint at /api/managed-stations.json, supports user stations with local persistence, and includes scripts to refresh station data from Radio.si.

Features

• Station library with search, category tabs, favorites, recents, sorting, and pagination.
• Country filtering plus a country picker to choose which Radio Browser countries are synced and shown.
• Audio playback with previous/next controls, volume/mute, and coverflow quick picks.
• Google Cast and AirPlay output support.
• User station management with local import/export/reset tooling.
• Managed catalog fallback chain: remote endpoint -> cached remote -> bundled stations.json.
• Production service worker with app shell caching, station sync cache, and periodic refresh registration.
• PWA install prompt and offline-friendly launch behavior.

Requirements

• Node.js 18+
• npm
• For production managed endpoint: PHP-enabled web server with rewrite support (Apache + .htaccess in this repo)

Getting Started

Install dependencies:

npm install

Run development server:

npm run dev

Build for production:

npm run build

Preview production build locally:

npm run preview

Deploy built assets with the included script:

bash sync.sh

Managed Catalog Endpoint

Runtime managed endpoint path:

/api/managed-stations.json

In production this is served by:

• public/.htaccess rewrite rule
• public/api/managed-stations.php

Response shape:

{
  "schemaVersion": 1,
  "updatedAt": "2026-04-29T07:39:58.374Z",
  "stations": []
}

In dev/preview, Vite middleware in vite.config.js serves the same envelope from stations.json.

If the endpoint is unavailable, frontend and service worker fall back to bundled public/stations.json.

Station Data Refresh

Refresh managed stations from Radio.si:

npm run update:stations

Refresh and rebuild in one command:

npm run update:stations:build

Custom source and output:

node scripts/update-stations.mjs <source-url> <output-path>

Cron Automation (Server)

Helper script:

bash scripts/cron-refresh-stations.sh

Update-only helper script:

bash scripts/cron-update-stations.sh

The script:

• acquires a lock file to prevent overlapping runs,
• runs station refresh and build,
• optionally runs DEPLOY_CMD,
• writes logs to /tmp/radioplayer-refresh-stations.log by default,
• rotates logs automatically when they exceed 1 MB, keeping 5 archives by default.

The update-only script:

• acquires its own lock file,
• runs only npm run update:stations,
• optionally runs POST_UPDATE_CMD,
• writes logs to /tmp/radioplayer-update-stations.log,
• uses the same log rotation behavior.

Example crontab (every 6 hours):

0 */6 * * * REPO_DIR=/opt/www/virtual/RadioPlayer DEPLOY_CMD='rsync -av --delete /opt/www/virtual/RadioPlayer/dist/ /opt/www/virtual/RadioPlayer/' /opt/www/virtual/RadioPlayer/scripts/cron-refresh-stations.sh

Example update-only crontab (every 2 hours):

0 */2 * * * REPO_DIR=/opt/www/virtual/RadioPlayer /opt/www/virtual/RadioPlayer/scripts/cron-update-stations.sh

Notes

• Service worker is only active in production builds. In dev, SW registrations and caches are cleared automatically.
• src/main.jsx registers background sync / periodic sync where supported.
• src/player.js also refreshes managed catalog on app focus after a timeout (fallback for browsers without periodic sync).
• sync.sh deploys dist/ only.
• If you edit stations manually, rerun npm run update:stations to resync from upstream when needed.
