atradio.fm

A social internet radio platform built on the AT Protocol. Search stations from radio-browser.info and TuneIn, stream them in the browser, and save favorites + your own stations to your own PDS (portable, user-owned data). Installable as a PWA.

Architecture

                 OAuth + reads/writes (in the browser, via atcute)
   apps/web (React SPA) ───────────────────────────────► your PDS (source of truth)
        │  reads other users' profiles                        │  fm.atradio.* records
        ▼                                                     │  (firehose)
   apps/api  ◄── XRPC (/xrpc/fm.atradio.*) ── discovery       ▼
   Express + Drizzle + Postgres  ◄── Jetstream consumer ◄── Jetstream (×4 hosts)
   (the AppView / index)

• Auth + your own data are 100% client-side (@atcute/oauth-browser-client). Favorites/stations are written straight to your PDS as fm.atradio.* records — no auth server.
• apps/api is a read-only AppView: a Jetstream consumer indexes those records into Postgres, and XRPC endpoints serve them (for public profiles and discovery), plus the atradio Connect hub.
• apps/media-proxy (Gleam/BEAM) is a stateless reverse-proxy for radio streams, TuneIn, artwork, and ICY "now playing" — split out so the streaming workload scales independently.

Stack

• Monorepo: Turborepo + Bun workspaces; toolchain pinned via mise
• Web: React 19, Vite, Tailwind v4, HeroUI v3, TanStack Router/Query, Jotai, Vitest
• AT Proto: @atcute/* (browser OAuth, client, identity-resolver, tid)
• API: Express, Drizzle ORM, Postgres, ws (Jetstream), Zod, consola
• Lexicons: Apple Pkl → lexicon JSON (pkl eval)
• Console: Babashka + Clojure + rebel-readline

Getting started

mise install        # node, bun, java, clojure, babashka
bun install
bun dev             # turbo: web (:3000) + api (:8080)

Set up the database (Postgres; TLS required):

cd apps/api
cp .env.example .env      # set DATABASE_URL, PORT
bun run db:generate       # generate migration from the Drizzle schema
bun run db:migrate        # apply it

Command console

./console           # Clojure + rebel REPL: (dev) (build) (migrate) (gen-lexicons) …
# or from tools/console:
bb tasks            # the same commands as Babashka tasks

AT Protocol

• Login is browser OAuth (atcute public client). Dev uses the 127.0.0.1 loopback client — open the app at http://127.0.0.1:3000 (not localhost). Prod uses the static apps/web/public/client-metadata.json.
• Gating: favoriting, adding, and removing stations require login (they open the login modal). Browsing, search, and playback stay public.
• Lexicons (packages/lexicons, NSID fm.atradio.*): station, favorite, and the getFavorites / getStations queries. Authored in Pkl:

  cd packages/lexicons && bun run pkl:gen   # pkl/defs/**.pkl → lexicons/**.json

• Data: your favorites/stations are records in your PDS (read on login, written with optimistic UI). Any user's profile is viewable at /profile/:did or /profile/:handle.

atradio Connect

Like Spotify Connect: when you're signed in, every atradio client you have open — the web app, the CLI/TUI, other terminals — shows up as a device on your account, and any of them can control the currently selected player. Pick a device and play/pause, volume, mute, and station changes route to it in real time.

• Device roster + presence. Each signed-in client registers over a WebSocket to the AppView's Connect hub (fm.atradio.connect, in apps/api/src/connect) and appears in a live device list; a disconnect drops it from the roster.
• Remote control. Any device can drive the target player — load a station, play/pause, set volume, mute — while playback state (now-playing, volume, playing/paused) streams back to every device.
• Authenticated per account. Connections are keyed to your DID and authenticated with an atproto service-auth JWT (com.atproto.server.getServiceAuth), so only your own clients join — logged-out clients don't participate.
• Drives your listening status. Your fm.atradio.actor.status record is set from Connect and cleared automatically once none of your devices are playing.
• Headless devices. Run atradio --no-tui (or install it as a service) to keep a terminal online purely as a controllable speaker — see the CLI README.

Backend (apps/api)

• Jetstream consumer connects to all four official instances simultaneously (jetstream{1,2}.us-{east,west}.bsky.network) for redundancy, filtering fm.atradio.favorite / fm.atradio.station, and upserts into Postgres (users, favorites, stations) with a resumable cursor. Duplicate events across hosts are harmless (idempotent upserts keyed by record uri).
• XRPC (open CORS, read-only): fm.atradio.getFavorites, fm.atradio.getStations (?actor=<did|handle>&limit&cursor), plus getRecentStations / getPopularStations for discovery.
• Media proxies (stream / TuneIn / image / ICY) now live in the dedicated apps/media-proxy service — point the web app at it with VITE_MEDIA_PROXY.

Deployment

• Static-host apps/web/dist/ (includes the PWA service worker + client-metadata).
• Run the API via the systemd/ units (atradio-api + atradio-jetstream) — see systemd/README.md.

Notes

• Use bun run test, not bun test (the latter runs Bun's built-in runner).
• ICY "now playing" is best-effort — many stations expose no metadata.
