Previously every reload-bundle killed and restarted all pipelines.
Now:
- WARM_CAMERAS map: camera_id → (pipeline, paintable)
- On reload: stop only pipelines for cameras no longer needed
- Needed = cells with content_type=camera + layout.preload_camera_ids
- Reuse existing pipeline+paintable, attach to new Picture widget
- Preloaded cameras keep decoding even when not visible
Achieves the "zero perceived latency" layout swap goal from CLAUDE.md
when cameras overlap between layouts.
- shared/nodered-bridge.ts: fire-and-forget POST to Node-RED HTTP-in
- api-http: kiosk event endpoint now forwards to Node-RED at /in/<topic>
- Best-effort, never blocks. 3s timeout, warn on failure.
- sec-config: noderedUrl on api-http (defaults to http://127.0.0.1:1880)
Node-RED flows can attach http-in nodes at /in/<topic> to receive
camera motion, GPIO events, etc. Inbound commands (Node-RED → server)
go through the admin API with admin Bearer token (no new endpoints
needed for v0.1).
Rust kiosk:
- web cells now use webkit6 WebView (load_uri)
- html cells use WebView.load_html (full HTML rendering)
- query_displays() reads /sys/class/drm/ for connected HDMI/DP outputs
- Heartbeat reports display geometry every 60s
Server:
- /api/kiosk/heartbeat accepts displays array
- Syncs kiosk-reported displays to display records
- Updates dimensions when changed, creates new displays for new ports
UI improvements:
- Click cell → htmx swaps in edit form inside the cell (no page reload)
- Cancel re-fetches cell in read mode
- Save returns updated cell HTML, htmx swaps it
- Edit form includes Width/Height inputs for col_span/row_span
- Inline +W/-W/+H/-H buttons on each cell for quick resize
- Add (+) and delete (×) buttons also htmx — only the grid swaps
Routes:
- GET /admin/layouts/:id/cells/:cellId — cell fragment (read mode)
- GET /admin/layouts/:id/cells/:cellId/edit — cell fragment (edit mode)
- POST /admin/layouts/:id/cells/:cellId/resize — adjust span by delta
- All cell ops return fragment if hx-request header present, else 302
All mutations trigger notifyKiosks() — kiosks live-update via WS.
- Migrations now run exactly once per DB lifetime, tracked via
SQLite's user_version PRAGMA
- Re-runs become no-ops after schema reaches target version
- v0.2 also made defensive — skips if template_id already dropped
Fixes "no such column: layouts.template_id" on second startup after
v0.5 rebuild dropped the legacy columns.
Server side:
- service-coordinator-ws: full WS implementation using ws package
- Auth via ?token=<kiosk_key> query param
- Coordinator registry for cross-plugin notification
- Admin mutations call notifyKiosks() → server pushes reload-bundle
- 30s ping/pong heartbeat
Kiosk side:
- Rust ws_client with tokio runtime + tokio-tungstenite
- Auto-reconnect with exponential backoff (1s → 60s cap)
- On reload-bundle: re-fetches bundle, re-renders layout
- Pong replies to server pings
Also fix: auto-suffix kiosk name on UNIQUE collision (re-pair with
same hostname no longer fails).
- Cells own position directly (row/col/row_span/col_span)
- Drop regions JSON from layouts (cells ARE the regions)
- Drop is_default from layouts (display.default_layout_id owns)
- Drop grid_cols/grid_rows from layouts (computed from cells)
- Layout new form: name, description, priority, resets_idle_timer only
- Layout edit: visual grid builder, + buttons on cell edges,
click cell to assign content
- Bundle cells now carry position directly
- Rust kiosk attaches widgets using cell position
- Migration v0.4: backfills cell positions from old region map
- Eliminated layout_templates as separate entity — regions/grid now
live directly on layouts
- Displays created from kiosk pairing (not standalone), each display
has kiosk_id FK
- Removed Templates from sidebar nav and all template routes/pages
- Layout creation uses preset buttons (fullscreen, 2x2, 1+3, 3x3)
that set regions directly on the layout
- Setup no longer creates default display/layout (deferred to pairing)
- Pairing creates HDMI-0 display for new kiosk
- Bundle reads regions from layout directly, no template lookup
- Rust kiosk updated to match new bundle format
- DB migration adds regions/grid_cols/grid_rows to layouts, kiosk_id
to displays, copies existing template data
- Camera add/edit: split RTSP URL into host/port/path/user/pass fields
- Camera edit updates stream URI when RTSP URL changes
- service-coordinator-ws: HTTP health stub (WS upgrade deferred)
- Repository: added updateCameraStream
- CLAUDE.md: full rewrite reflecting current architecture
cookieMac was using encryptString which generates a random IV per
call, making the HMAC key non-deterministic. Cookie signed at login
could never verify on subsequent requests. Now uses deriveKey(info)
which uses HKDF — deterministic for same server key.
h3 v2's setCookie modifies event response headers but doesn't
carry them when handler returns a raw Response object. Build
Set-Cookie header manually in redirect helpers instead.
h3 v2's html() is a tagged template literal, not a function that
accepts a string. JSX-rendered markup passed directly causes
"first.reduce is not a function". Created htmlPage() helper that
wraps markup in a proper Response with text/html content type.
BSB plugins should be actual services (own port, lifecycle, resource
ownership). Moved secrets, auth, pairing, bundle, nodered-bridge, and
cec-relay from plugin folders to shared modules under server/src/shared/.
4 BSB plugins remain: service-store, service-admin-http,
service-api-http, service-coordinator-ws.
service-admin-http now initializes secrets + auth as plain modules in
init() using the store repo from the plugin-registry singleton. No
more setSiblings() hack or inter-plugin wiring.
sec-config.yaml updated: secrets/auth config moved into
service-admin-http, pairing config into service-api-http, nodered
config into service-coordinator-ws.
