+
+## Project Overview
+
+Ummgoban Web View is a pnpm monorepo containing React web applications that integrate with a React Native mobile app. The web views are embedded in the mobile app and communicate via a custom message passing system.
+
+**Key Architecture:**
+- **Client App** (`apps/client`): Customer-facing web view for browsing markets, managing cart/bucket, and placing orders
+- **Admin App** (`apps/admin`): Admin interface (minimal implementation currently)
+- **UI Package** (`packages/ui`): Shared React component library with Storybook, built with shadcn/ui and Tailwind CSS
+- **Shared Package** (`packages/shared`): Common utilities, types, and React Native bridge communication logic
+
+## Development Commands
+
+### Running Applications
+
+```bash
+# Client app (customer web view)
+pnpm dev:client        # Standard dev server
+pnpm dev:client-all    # Run client + watch UI and shared packages concurrently
+
+# Admin app
+pnpm dev:admin
+
+# Individual packages in watch mode
+pnpm dev:ui
+pnpm dev:shared
+```
+
+### Building
+
+```bash
+# Build all packages and apps
+pnpm build
+
+# Build specific apps (automatically runs prebuild for packages)
+pnpm build:client
+pnpm build:admin
+
+# Build specific packages
+pnpm build:ui
+pnpm build:shared
+```
+
+### Testing and Linting
+
+```bash
+# Run tests (uses vitest workspace)
+pnpm --filter @packages/shared test              # Run tests once
+pnpm --filter @packages/shared test:watch        # Watch mode
+pnpm --filter @packages/shared test:coverage     # With coverage
+
+# Linting (runs across all workspaces)
+pnpm lint
+
+# Code formatting
+pnpm prettier
+```
+
+### Preview Builds
+
+```bash
+pnpm preview:client    # Preview client build on port 8080
+pnpm preview:admin     # Preview admin build
+```
+
+## Architecture
+
+### React Native Bridge Communication
+
+The client app communicates with the React Native mobile app through a custom event-based messaging system:
+
+1. **App → Web Messages** (`@packages/shared/message/types/app-to-web.type.ts`):
+   - `INIT`: Platform info and timestamp
+   - `SAFE_AREA_INSETS`: Device safe area insets for UI layout
+   - `WEB_NAVIGATION`: Navigation commands from native app
+   - `NATIVE_HISTORY`: Native navigation history
+   - `AUTHORIZATION`: Session/auth tokens passed from native
+
+2. **Web → App Messages** (`@packages/shared/message/types/web-to-app.type.ts`):
+   - Message types sent from web to native using `postToApp()` utility
+
+3. **Implementation**:
+   - `useRNMessage()` hook (`apps/client/src/hooks/use-RN-message.ts`) listens for `APP_MESSAGE` events
+   - Updates Zustand stores for safe area, navigation state, and session
+   - Uses `window.addEventListener('APP_MESSAGE')` and dispatches `APP_MESSAGE_LISTENER_READY`
+
+### State Management
+
+Uses Zustand for global state (`apps/client/src/store/`):
+- `native-message.store.ts`: React Native connection state, navigation, and platform info
+- `profile.store.ts`: User session and authentication
+- `safearea.store.ts`: Device safe area insets for layout
+
+### API Layer
+
+The client app uses a singleton `ApiClient` class (`apps/client/src/api/ApiClient.ts`):
+- Axios-based HTTP client with automatic token refresh
+- Handles 401 errors by attempting to refresh access token using refresh token
+- Environment-based base URLs (`__DEV__`, `__PROD__`, `__LOCAL_DEV__`, `__LOCAL_PROD__`)
+- Stores session in storage using utilities from `@packages/shared`
+- API modules organized by domain: `auth/`, `buckets/`, `markets/`
+- Each module exports:
+  - `client.ts`: API request functions
+  - `model.ts`: Request/response type definitions
+  - `query.ts`: React Query hooks (uses `@tanstack/react-query`)
+
+### Routing and Domain Structure
+
+The client uses React Router v7 (`react-router`) with a domain-based organization:
+- Routes are organized in `apps/client/src/domain/` by feature area
+- Each domain exports page components (e.g., `cart/`, `detail/`, `not-found/`)
+- Shared components are in `apps/client/src/component/`
+- Uses `react-router` for routing (not react-router-dom)
+
+### Build System
+
+**Packages** (`ui` and `shared`):
+- Built with Rollup, outputting both ESM (`.mjs`) and CJS (`.cjs`) formats
+- Watch mode available for development (`pnpm dev:ui`, `pnpm dev:shared`)
+- Must be built before apps can use them in production builds
+
+**Apps** (`client` and `admin`):
+- Built with Vite and TypeScript
+- TypeScript compilation (`tsc -b`) runs before Vite build
+- Environment variables defined via Vite `define` (e.g., `__DEV__`, `__PROD__`)
+
+### Environment Handling
+
+The client app supports multiple environments:
+- `NODE_ENV='local-dev'`: Local development with proxy to dev API (`/api-dev` → `https://dev.ummgoban.com/v1`)
+- `NODE_ENV='local-prod'`: Local development with proxy to prod API (`/api-prod` → `https://api.ummgoban.com/v1`)
+- `NODE_ENV='development'`: Deployed development environment
+- `NODE_ENV='production'`: Deployed production environment
+
+Vite config uses proxy in local modes and direct API calls in deployed environments.
+
+### TypeScript Configuration
+
+- Each app and package has its own `tsconfig.json`
+- Apps use `tsconfig.app.json` for source code and `tsconfig.node.json` for build configs
+- Packages use `tsconfig.build.json` for build output
+- Path aliases: Client app uses `@/` for `src/` directory
+
+### Styling
+
+- **Tailwind CSS** for utility-first styling
+- **shadcn/ui** component primitives in UI package
+- **Radix UI** for accessible components
+- Prettier config: 120 char width, 2 space indent, double quotes
+
+## Component Development
+
+The UI package uses Storybook for component development:
+
+```bash
+cd packages/ui
+pnpm storybook              # Run Storybook on port 6006
+pnpm build:storybook        # Build static Storybook
+```
+
+Components are organized in `packages/ui/src/components/`:
+- `ui/`: Base components (buttons, cards, etc.)
+- `layout/`: Layout components
+- `feedback/`: User feedback components (modals, alerts)
+- `utility/`: Utility components
+
+## Important Patterns
+
+1. **Session Management**: Sessions are stored using `getStorage`/`setStorage` from `@packages/shared` and automatically refreshed by ApiClient interceptor on 401 errors.
+
+2. **Error Handling**: Use `CustomError` class (`apps/client/src/api/CustomError.ts`) for API errors.
+
+3. **React Query**: API calls should use React Query hooks (defined in `query.ts` files) for caching and state management.
+
+4. **Cross-platform Support**: The client app must work both in React Native WebView and standalone browser. Check `platform` from native message store to conditionally handle features.
+
+5. **Build Dependencies**: When modifying `packages/ui` or `packages/shared`, either run watch mode or rebuild before testing changes in apps.
