Add apps/desktop, a thin Tauri v2 shell wrapping the SAME @parking/web SPA so the desktop and browser UIs never drift: dev loads the Vite dev server (HMR), prod bundles the web app's dist/. No business logic in the shell (device/auth/ ledger stay in @parking/server); deny-by-default capabilities. apps/web (single UI source of truth): - lib/origin.ts: centralize the backend origin (API_BASE/apiUrl/wsUrl from VITE_API_BASE); no-op in the browser, lets the desktop build target Fastify. - lib/kiosk.ts: block the right-click context menu in PROD only (dev keeps it + devtools). - lib/desktop-updater.ts: prompt-on-update auto-update (no-op in browser/offline) → downloadAndInstall + relaunch; i18n update.* keys (sq+en). - .env.production: VITE_API_BASE wired to the Fastify origin for the bundle. Desktop: - window starts maximized (not fullscreen — operator keeps OS access). - auto-update via tauri-plugin-updater + -process; self-hosted endpoint is a PLACEHOLDER to fill in. Updater keypair: pubkey embedded in tauri.conf.json; private key + password kept OUTSIDE the repo (~/.parking-updater-keys) and as TAURI_SIGNING_* build secrets. - Turbo build is a no-op; the real signed bundle is `pnpm --filter @parking/desktop bundle` (verified → .deb/.rpm/.AppImage + .sig signatures). Verified: cargo check clean; turbo run build lint 14/14 green; i18n parity holds; no key/sig/bundle artifacts in the repo. Wiki (security + desktop analysis recorded alongside): - new concepts/tpm.md (TPM 2.0: how it works, sealed-LUKS auto-unlock + non- extractable signing key, limits — live-root, bus-sniff — TPM-vs-ATECC608 by platform). - new decisions/desktop-shell-tauri.md (Tauri v2 over Electron; best-case Ubuntu 26.04 LTS, worst-case Windows+WSL → kiosk browser; full as-built). - pull-the-disk attack trace on append-only-event-chain; ATECC608 not-in-a-PC caveat; cross-links from disk-os-hardening / threat-model. - open-questions #11 (appliance WebKitGTK), #12 (TPM hardening impl), #13 (startup verifyChain self-check); index/overview/log/standing-decisions.

@parking/desktop — Tauri v2 kiosk shell
A thin native desktop window over the @parking/web SPA. It contains no UI and no business
logic of its own: the window renders the same web app the browser does, so the desktop and the
browser stay identical and never drift. Device/auth/ledger logic stays in @parking/server. See
wiki/decisions/desktop-shell-tauri.md.
How the "same look & functionality" guarantee works
| Source of the UI | |
|---|---|
Dev (tauri dev) |
the window loads http://localhost:5173 — the @parking/web Vite dev server. Edit a component in apps/web → HMR updates the desktop window live. |
Prod (tauri build) |
the window bundles apps/web's built dist/. beforeBuildCommand rebuilds the SPA first. |
There is only one UI codebase (apps/web); this package just wraps it.
Backend connection
The SPA talks to Fastify over HTTP/WS. In a browser that's same-origin (relative /api). In the
desktop build the bundled assets load from tauri://localhost, so set VITE_API_BASE (read at
web build time — see .env.example) to the appliance's Fastify origin, e.g.
http://127.0.0.1:3000. The CSP connect-src in tauri.conf.json is already allowed for that
origin, and the backend must include the Tauri origin in WS_ALLOWED_ORIGINS for the live feed.
Commands
pnpm --filter @parking/desktop dev # native window over the web dev server (HMR)
pnpm --filter @parking/desktop bundle # build the SPA + bundle the desktop app (.deb/.rpm/.AppImage)
buildis a no-op in this package soturbo run buildstays fast — the real desktop bundle (compiles Rust, minutes long) is the explicitbundlescript above.
Requires the Rust toolchain and (on Linux) WebKitGTK 4.1 + libsoup-3 dev libraries. Under WSL2 the window needs a display (WSLg or an X server).
Not here (deliberately)
Kiosk lockdown (fullscreen/no-decorations), auto-update, code signing, and launching Fastify from the shell are out of scope for the scaffold — on the appliance Fastify runs as its own service and this shell connects to it.
