hamid 94fdcbe0d1 frontend phase 0: app shells, design system & data/contract patterns
Turn the starter into the Balinyaar foundation for the three actor
experiences and lock in the patterns later phases copy.

- Cleanup: remove toastDemo namespace, placeholder home page, and the two
  dead icons; fix BottomBar to use usePathname (locale-aware active tab).
- Three actor shells under (private-routes), no layout above [locale]:
  customer (customer) group with the 5-tab bottom nav; nurse (/nurse) and
  admin (/admin) on the shared sidebar engine. Role model via constants/roles
  + useActorRole (defaults to customer until roles land in f1-b2).
- services/{domain} reference (patients) with a mock behind a config seam,
  hierarchical query keys, deliberate staleTime, and mutation invalidation;
  shared ApiEnvelope/Paginated wire types + unwrap() in lib/api/types.
- Money (integer-safe IRR/Toman) + Shamsi-date utils; toEnglishDigits helper.
- Shared composites, each tested: OtpInput, PhoneNumberField, StepperHeader,
  StatusChip, PlaceholderScreen.
- i18n: seed nav/common/shell/patients in both locales; document namespace
  conventions. Update client/CLAUDE.md Project Structure + fix ColorSchemeScript
  doc drift. Add phase report, STATUS, and REQ-001 (envelope/casing/pagination).

Gate: npm run check + test:ci green (72 tests); build green with NEXT_PUBLIC_API_URL.

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

  1. Install dependencies:

    npm install
    
  2. Create your local environment file from the sample and adjust values:

    cp .env.sample .env
    

    Key variables (all NEXT_PUBLIC_* are exposed to the browser):

    Variable Purpose
    NEXT_PUBLIC_ENV development | preview | production
    NEXT_PUBLIC_DEBUG true enables extra console logging
    NEXT_PUBLIC_PUBLIC_URL Public URL of the site
    NEXT_PUBLIC_API_URL Base URL of the backend API (the server project)
  3. Run the dev server:

    npm run dev
    

    Open http://localhost:3000. The root path redirects to /fa (default locale).

Available scripts

Script Description
npm run dev Start the development server (Turbopack) with hot reload
npm run build Production build
npm run start Serve a production build
npm run lint Lint with ESLint (flat config, eslint .)
npm run lint:fix Lint and auto-fix
npm run type Type-check with tsc --noEmit
npm run check Type-check and lint (the quality gate)
npm run format Format the codebase with Prettier
npm test Run Jest in watch mode
npm run test:ci Run Jest once (CI)

Project structure

src/
├── app/[locale]/    App Router routes, grouped into (public-routes) and (private-routes).
│                    [locale]/layout.tsx is the ROOT layout (renders <html>/<body>).
├── components/      Reusable UI: common App* components (AppButton, AppIcon, …) + UserInfo
├── constants/       App-wide named constants (routes, headers, …)
├── hooks/           Custom hooks (auth, layout/mobile, events, window size)
├── i18n/            next-intl routing + request config
├── layout/          PublicLayout / PrivateLayout + TopBar, SideBar, BottomBar
├── lib/             api (client/server fetch), auth (JWT/session helpers), cookies, query, toast
├── services/        Domain services: {domain}/{types,keys,apis,hooks}
├── context/         React context providers — auth/ is AuthContext (server-seeded session state)
├── theme/           ThemeProvider, palettes, tokens.css, typography, direction
└── utils/           Helpers (storage, navigation, env, text, types)

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

For the full agent-oriented map of conventions and where to make changes, see CLAUDE.md.

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); fa is the default and is RTL.
  • Authentication is cookie-based (access_token / refresh_token). Session state lives in AuthContext (src/context/auth/), seeded on the server from the request cookie so the first render reflects the real session; cookies are managed through src/lib/cookies/ and the src/services/auth/ hooks. The API base URL comes from NEXT_PUBLIC_API_URL.
