First CRUD increment. Click "+ Add entity" on the Dashboard
toolbar → modal opens → form with entity_id / state / attributes
fields → Create validates client-side then POSTs /api/states/<id>
→ modal closes, toast confirms, dashboard refreshes.
New components:
frontend/src/components/Modal.ts (~110 LOC) — reusable accessible
overlay. open property; closes on Escape and backdrop click.
Heading prop; default + footer slots.
frontend/src/components/EntityForm.ts (~130 LOC) — three-field form
with public requestSubmit()/requestCancel() methods. Client-side
validation:
- entity_id matches /^[a-z][a-z0-9_]*\.[a-z][a-z0-9_]*$/
- state non-empty
- attributes parses as a JSON object (rejects array/scalar)
Emits hc-entity-submit / hc-entity-cancel events for host to
handle. Footer buttons live in the host (modal slot=footer).
frontend/src/pages/Dashboard.ts (+60 LOC) — toolbar with
"+ Add entity" button, modal state, POST handler that wraps
fetch with bearer token, success toast (3 s), refresh().
Browser-verified end-to-end (real homecore-server :8123):
- Toolbar button visible: Y
- Modal opens: Y
- 3/3 validation paths fire correctly:
BadID → "entity_id must match domain.snake_case"
blank state → "state must not be empty"
[1,2,3] attrs → "attributes must be a JSON object"
- Successful create: light.test_bulb POSTed; modal closes; toast
"Created light.test_bulb = on"; grid count went 10 → 11
- Persistence: hard reload, count stays
- 0 console errors (Lit dev-mode notices excluded)
Note: TypeScript caught a name collision — `attributes` is reserved
on HTMLElement (NamedNodeMap). Renamed the Lit @property to
`entityAttrs` so the class extends LitElement cleanly.

@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.
