react-librespot-controller

A squeezebox-alike React frontend for controlling go-librespot.

Use it as:

• a standalone page for touchscreens
• an embedded component in internal dashboards

UI Scope

• Layout modes: auto, default, widescreen, portrait
• Views: Info, Playlists, Queue, Settings
• Interactive album art card: tap to browse the current album, playlist, or show
• In-app navigation from now playing metadata to album, artist, and show details
• Browse playlists: view tracks with lazy-loaded metadata, play individual tracks
• Browse artists: portrait image, biography, top tracks, albums, singles, related artists
• Browse albums: tracklist with durations, explicit badges, clickable artist links
• Browse shows: episodes with durations and publish dates
• Playlist cards with cover art, name, description, owner, track count
• Paginated playlist loading with infinite scroll
• Client-side image URL normalization for Spotify CDN compatibility
• Comes with a set of preset themes and sleep timer
• Podcast controls include skip back 15s and skip forward 30s

Backend Requirements

This UI needs a go-librespot instance with:

• HTTP API: player controls, metadata endpoints (/metadata/rootlist, /metadata/playlist/{id}, /metadata/track/{id}, /metadata/album/{id}, /metadata/artist/{id}, /metadata/show/{id}, /metadata/episode/{id})
• WebSocket event stream at /events
• All metadata is fetched via Spotify's native Mercury/protobuf protocols (no Spotify Web API keys needed)

Standalone Setup

Create a .env file:

REACT_APP_API_BASE_URL=http://apollo:3678
REACT_APP_WS_URL=ws://apollo:3678/events
REACT_APP_KIOSK_MODE=false
REACT_APP_HIDE_ON_DISCONNECT=false
REACT_APP_LAYOUT=auto

Install and run:

npm install
npm run test
npm run static
npm run build

Commands:

• npm run test: starts the local demo app
• npm run static: creates the static app build
• npm run build: builds the npm package output in dist/

Module Setup

Install:

npm install --save @stronk-tech/react-librespot-controller

Use:

import MediaPlayer from "@stronk-tech/react-librespot-controller";

<MediaPlayer
  websocketUrl="ws://apollo:3678/events"
  apiBaseUrl="http://apollo:3678"
  hideOnDisconnect={false}
  kioskMode={false}
  layout="auto"
  theme="tokyo-night"
/>;

Props

• websocketUrl: WebSocket URL for go-librespot events
• apiBaseUrl: HTTP API base URL for go-librespot
• hideOnDisconnect: hides the component when API connection is down
• kioskMode: uses full-screen behavior
• layout: auto, default, widescreen, portrait
• theme: optional preset name; if omitted, saved theme is used, default is tokyo-night

tokyo-night, tokyo-night-light, dracula, nord, catppuccin, catppuccin-light, gruvbox, gruvbox-light, one-dark, github-dark, rose-pine, solarized, solarized-light, ayu-mirage
