Three domain services (mirroring the patients/nurse template): services/geography (cached province→city→district lookups; Infinity staleTime + shared geographyKeys), services/addresses (address book CRUD + set-primary; single-primary invariant), and services/serviceAreas (coverage add/remove; areaExists dup-guard, districtId=null = whole city). Four tested composites in src/components/geography: CascadingRegionSelect (drives the cascade queries), AddressMapPicker (map-pin stand-in emitting real lat/lng), AddressForm, AddressCard. Screens: customer address book (/addresses, reached from the profile hub) and nurse coverage editor (/nurse/coverage, new sidebar tab, inline duplicate block + 409). Adds geo/address/coverage i18n namespaces (both locales), location/delete/coverage icons, ADDRESSES/NURSE_COVERAGE routes. Consumes the b4 geography-addresses contract; filed REQ-008 (accept the map pin on create/update) and REQ-009 (provinceId on CustomerAddressDto) for gaps. Gate: npm run check + npm run test:ci (129, +17) + npm run build all green. A 5-dimension adversarial review fixed 3 findings (map-marker RTL transform, page_size→pageSize pagination casing, coverage districts-scope dead-end on district-less cities).

Balinyaar — Web Client
Frontend for Balinyaar, a trust-first home-nursing marketplace in Iran. Built with Next.js 16 (App Router), React 19, TypeScript, and Material UI (MUI) v9.
It ships with internationalization (fa/en, RTL-first), a no-flash light/dark theme system, a small
library of reusable App* components, TanStack Query for server state, and public/private layout
shells wired for cookie-based authentication.
AI agents: read CLAUDE.md — it is the engineering contract (architecture, providers, data fetching, theming, i18n, cookies, and the rules every change must follow).
Requirements
- Node.js 18+ and npm
- The backend API (see
../server) running for authenticated features
Getting started
-
Install dependencies:
npm install -
Create your local environment file from the sample and adjust values:
cp .env.sample .envKey variables (all

Run the dev server:
npm run devOpen http://localhost:3000. The root path redirects to
/fa(default locale).

The @/* import alias maps to src/* (see tsconfig.json).
Translation files live in messages/ (en.json / fa.json) and must stay in sync.

Notes
- This is a server-rendered Next.js app (App Router + middleware + server-side cookies) — not a static export.
- Internationalization is locale-prefixed (
/fa,/en);fais the default and is RTL. - Authentication is cookie-based (
access_token/refresh_token). Session state lives inAuthContext(src/context/auth/), seeded on the server from the request cookie so the first render reflects the real session; cookies are managed throughsrc/lib/cookies/and thesrc/services/auth/hooks. The API base URL comes fromNEXT_PUBLIC_API_URL.
