The stage split is the thing an fps-shortfall report is diagnosed from, and it cannot be read without knowing the backend behind it: a p50 `submit` of 10 ms means "the GPU's CSC+encode throughput is the ceiling" on one backend and something else entirely on another. The capture's meta carried the mode, codec and client but neither the encoder nor the GPU, so every report so far cost a round-trip asking which one it was. Both come from `pf_gpu::active()` — the record the encoder open itself writes — so they name the branch that really opened rather than a re-derived guess that goes stale the moment a backend gains an internal fallback. Read once per capture, not per frame. The console shows them next to the mode in the recording's header. Both fields are `serde(default)`, so a recording made before this still loads and simply omits them. Refs #9 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
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:47992
# 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=47992 HOST=0.0.0.0 \
PUNKTFUNK_UI_PASSWORD=… PUNKTFUNK_MGMT_TOKEN=… \
PUNKTFUNK_MGMT_URL=https://127.0.0.1:47990 \
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).
# The host's self-signed mgmt cert is accepted only for the proxy's loopback hop, scoped in code
# (Bun per-request TLS: server/routes/api/[...].ts) — no process-wide NODE_TLS_REJECT_UNAUTHORIZED.
# 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 :47992 (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 (h3useSession, AES-GCM).server/middleware/auth.tsgates every request — pages redirect to/login,/apireturns 401 — and fails closed (503) ifPUNKTFUNK_UI_PASSWORDis 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_TOKENserver-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-corepeer-requires Vite ≥ 7 — on Vite 6 the build's prerender/post-build hook silently doesn't run.@vitejs/plugin-reactmust 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 itvite buildonly emits client+SSR bundles, no deployable server. The Nitrobunpreset makes.output/server/index.mjsBun-runnable.
Codegen
Generated code is not committed (gitignored) — reproduced from sources:
bun run codegen— regenerate the API client (orval) + i18n runtime (paraglide). Runs onbun install(prepare) and beforedev/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, thenbun run api:gen.
