punktfunk web — management console

The browser UI for the punktfunk host's management REST API (crates/punktfunk-host/src/mgmt.rs, OpenAPI at api/openapi.json). It shows live status, host capabilities, paired clients, the pairing-PIN flow, and session controls.

Stack: TanStack Start (full SSR) on Bun via Nitro v2 (bun preset) · React Query through orval codegen from the OpenAPI spec · @unom/ui — the shared punktfunk/unom design system the marketing site + docs are built on (Tailwind v4, animated components on the violet brand over dark chrome) · Paraglide i18n (en/de). Package manager + runtime: Bun.

The @unom registry mapping lives in .npmrc; the auth token comes from ~/.npmrc (or a CI secret).

Develop

# from web/  — Bun is the toolchain (https://bun.sh)
bun install               # runs `prepare` → codegen (orval + paraglide)
bun run dev               # http://localhost:3000

# The dev server proxies /api → https://127.0.0.1:47990 (the host's mgmt API; it serves HTTPS
# with the host's self-signed identity cert — the dev proxy uses `secure: false`).
# Point it elsewhere: PUNKTFUNK_MGMT_URL=https://<host>:47990 bun run dev

Start a host with the management API up:

# from the repo root — `serve` brings up the native punktfunk/1 plane + the mgmt API (the console
# only needs the mgmt API; add --gamestream too if you also want the Moonlight surface):
WAYLAND_DISPLAY=wayland-kde XDG_CURRENT_DESKTOP=KDE \
  cargo run -rp punktfunk-host -- serve
# loopback :47990, no token (a token is mandatory for non-loopback binds).

If the host runs with --mgmt-token, set it under Settings → API token (stored in localStorage, sent as Authorization: Bearer … by the orval fetcher).

Build & run (Nitro + Bun)

The console runs on bun (Bun.serve is a Bun API — node can't run it): Nitro's bun preset plus a custom entry (nitro-entry/bun-https.mjs) that calls Bun.serve({ tls }), so it serves HTTPS (HTTP/1.1 over TLS) with the host's own identity cert (the cert native clients already pin). One trust anchor across the data plane, the mgmt API, and this console. (No HTTP/2 — Bun.serve has no h2 server — and no HTTP/3, which a browser won't speak against this self-signed, no-SAN host cert; a browser-trusted, SAN-matching cert + a fronting server would be needed, out of scope for a LAN console.)

bun run build             # → .output/  (Nitro `bun` preset + our Bun.serve TLS entry)
PORT=3000 HOST=0.0.0.0 \
  PUNKTFUNK_UI_PASSWORD=… PUNKTFUNK_MGMT_TOKEN=… \
  PUNKTFUNK_MGMT_URL=https://127.0.0.1:47990 NODE_TLS_REJECT_UNAUTHORIZED=0 \
  PUNKTFUNK_UI_TLS_CERT=~/.config/punktfunk/cert.pem \
  PUNKTFUNK_UI_TLS_KEY=~/.config/punktfunk/key.pem PUNKTFUNK_UI_SECURE=1 \
  bun run start           # = bun run .output/server/index.mjs
# PUNKTFUNK_UI_TLS_* unset ⇒ plain HTTP (local dev); both set ⇒ HTTPS (HTTP/1.1 over TLS).
# NODE_TLS_REJECT_UNAUTHORIZED=0 is only for the proxy's loopback fetch to the host's self-signed
# mgmt cert; the console makes no other outbound TLS calls. See .env.example.
bun run lint              # tsc --noEmit

The built Nitro bun server SSR-renders the app and is the only thing exposed on the LAN. Run it on the same box as the host; it serves the console over HTTPS on :3000 (or $PORT).

Auth (backend-for-frontend)

Single-user, login-gated. Config via env (see .env.example):

• The console requires a login (PUNKTFUNK_UI_PASSWORD). On success the server sets a sealed session cookie (h3 useSession, AES-GCM). server/middleware/auth.ts gates every request — pages redirect to /login, /api returns 401 — and fails closed (503) if PUNKTFUNK_UI_PASSWORD is unset, so a misconfigured LAN server admits no one.
• The bearer-token admin surface of the management API is loopback-only — the host honors a bearer token only from a loopback peer, so the admin API is never LAN-exposed. The web server holds PUNKTFUNK_MGMT_TOKEN server-side and injects it when proxying /api/** → PUNKTFUNK_MGMT_URL (loopback; server/routes/api/[...].ts). The token never reaches the browser; the browser only ever holds the session cookie. (The host also binds the read-only surface — host status + the game library — to the LAN so paired native clients can fetch it directly over mTLS; that path uses client certs, not the token, and never touches this console.)

So: browser ──password──▶ web server (session cookie) ──mgmt token, server-side──▶ mgmt API. Run the host with a matching token: cargo run -rp punktfunk-host -- serve + PUNKTFUNK_MGMT_TOKEN=… (or --mgmt-token …). vite dev has no gate (localhost-only) and proxies straight to the loopback mgmt API.

Toolchain notes (load-bearing): TanStack Start's start-plugin-core peer-requires Vite ≥ 7 — on Vite 6 the build's prerender/post-build hook silently doesn't run. @vitejs/plugin-react must match Vite (v5 ↔ Vite 7, v6 ↔ Vite 8); it's required even for dev (TanStack Start's dev mode needs the React Refresh runtime, else a blank screen). Nitro is the server target — without it vite build only emits client+SSR bundles, no deployable server. The Nitro bun preset makes .output/server/index.mjs Bun-runnable.

Codegen

Generated code is not committed (gitignored) — reproduced from sources:

• bun run codegen — regenerate the API client (orval) + i18n runtime (paraglide). Runs on bun install (prepare) and before dev/build (pre* for orval; the Vite plugin compiles paraglide on dev/build).
• After a management-API change, regenerate the spec on the Rust side first: cargo run -p punktfunk-host -- openapi > api/openapi.json, then bun run api:gen.
