Before: clicking Dashboard / States / Services / Settings highlighted
the active nav button but the page content never changed. AppShell
dispatched `hc-navigate` events but no listener acted on them.
After (~232 LOC across 4 files):
- main.ts (+20 LOC) tiny router: NAV_TO_TAG maps nav id → page
custom element; on `hc-navigate`, swap the AppShell's child.
- pages/States.ts (~86 LOC) HA-style entity table with 5 s refresh.
- pages/Services.ts (~82 LOC) domain-grouped service registry,
friendly empty state when no services registered.
- pages/Settings.ts (~90 LOC) backend config readout + bearer-token
editor (localStorage["homecore.token"]).
Browser-verified all 4 nav clicks swap content; 0 console errors.
Dashboard → 10 entity cards; States → 10-row table; Services →
empty state (0 domains); Settings → config + token editor.

@ruvnet/homecore-frontend
HOMECORE web UI — built with Lit 3, TypeScript, and Vite. Design system mirrors the cognitum-v0 / v0-appliance dashboard (ADR-131).
Quick start
cd frontend
npm install
npm run dev # http://localhost:5173
The Vite dev server proxies /api → http://localhost:8123, so you need a
homecore-api-server (or the wifi-densepose-sensing-server crate) running on :8123.
Scripts
| Script | Description |
|---|---|
npm run dev |
Start Vite dev server on port 5173 |
npm run build |
TypeScript compile + Vite production bundle → dist/ |
npm run lint |
ESLint on src/ |
npm test |
Vitest unit tests (3 suites, jsdom) |

Design system
Colors, typography, and components mirror the cognitum-v0 dashboard
(http://cognitum-v0:9000/). Dark-only; no light-mode. Key tokens:
--hc-primary#19d4e5— teal (active nav, focus ring, CTA borders)--hc-accent#26d867— green (success, secondary CTA)--hc-bg#0b0e13— near-black navy page root- Font: Outfit (display) + JetBrains Mono (mono)
- Icons: Lucide (SVG,
stroke: currentColor, no icon font)
See docs/design/HOMECORE-FRONTEND-design-recon.md for the full recon.
Architecture notes
- Components are standard Lit
LitElementcustom elements — compatible with any HTML page and with Home Assistant's Lit-based frontend. - The REST client uses
fetch; the WS client usesWebSocket. Both accept a bearer token and are fully typed against the Rusthomecore-apiJSON shapes. - WASM:
vite.config.tsenables.wasmasset import. Hook up via dynamicimport('/path/to/module.wasm?init')when WASM bindings are ready.
