# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Project Overview

This is an HRMS (Human Resource Management System) check-in/check-out web application built for the Bangkok Metropolitan Administration (BMA). The application allows employees to record their work attendance using geolocation verification and camera features.

**Tech Stack:**
- Vue 3 with Composition API and TypeScript 4.7.4
- Vite for build tooling
- Quasar Framework for UI components
- Pinia for state management
- Vue Router for routing
- Keycloak for authentication
- ArcGIS API and Google Maps for location features
- PWA capabilities with offline support
- Docker deployment with nginx

**Development Server:** Runs on port 3008

## Common Commands

```bash
# Development
npm run dev                    # Start dev server on port 3008

# Building
npm run build                  # Build for production
npm run preview                # Preview production build on port 3008

# Testing
npm run test:unit              # Run unit tests with vitest
npm run test:e2e               # Run e2e tests with cypress
npm run test:e2e:dev           # Run cypress in dev mode

# Code Quality
npm run lint                   # Lint and auto-fix code
npm run format                 # Format code with prettier
npm run type-check             # TypeScript type checking

# Docker
docker buildx build --platform=linux/amd64 -f docker/Dockerfile . -t hrms-checkin:0.1
```

### Key Architecture Patterns

**Authentication Flow:**
- Uses Keycloak for SSO authentication
- Tokens stored in cookies with `BMAHRISCKI_KEYCLOAK_IDENTITY` key
- Auth state managed in `src/plugins/auth.ts`
- Router guards enforce authentication on protected routes
- 401 responses trigger automatic logout via axios interceptor

**State Management:**
- `stores/mixin.ts` - Global utilities (Thai date formatting, dialogs, loaders, error handling)
- `stores/chekin.ts` - Check-in history and status management
- `stores/privacy.ts` - Privacy consent management
- `stores/positionKeycloak.ts` - User position/role data

**API Layer:**
- Base axios instance in `src/plugins/http.ts` with automatic token injection
- API endpoints organized by feature in `src/api/`
- Environment-specific API URLs configured in `src/api/index.ts`
- Production API URL set via `VITE_API_URI_CONFIG` env variable

**Routing:**
- Main layout (`MainView`) wraps authenticated routes
- Protected routes require `meta.Auth: true`
- Auth check runs in router beforeEach guard
- Public routes: `/login`, `/auth`, `/reset-password`, `/history`

**Geolocation & Maps:**
- ArcGIS JS API for advanced mapping features
- Google Maps integration for location services
- Camera integration for check-in photo verification
- Privacy consent required before accessing camera/location

**Date/Time Handling:**
- Thai Buddhist calendar (BE) conversion (+543 years)
- Thai month names (full and abbreviated)
- `date-fns-tz` for timezone handling (Asia/Bangkok)
- Fiscal year calculation (October start)

### Component Conventions

- Components use Quasar UI components (`q-btn`, `q-dialog`, etc.)
- Thai language throughout the UI
- Custom dialogs use `CustomDialog.vue` component
- Loading states use Quasar's `QSpinnerCube`
- Error dialogs prevent overlap with `activeErrorDialog` tracking

### Localization

- Quasar configured with Thai language (`quasar/lang/th`)
- All UI text in Thai
- Date formatting uses `date2Thai()` and `monthYear2Thai()` from mixin store
- Status labels translated: ABSENT→'ขาดราชการ', NORMAL→'ปกติ', LATE→'สาย'

### Environment Variables

Required in `.env.production`:
- `VITE_API_URI_CONFIG` - Production API base URL
- `VITE_URL_SSO` - Keycloak SSO logout URL
- `VITE_URL_USER` - User service URL for redirects
- `VITE_URL_LANDING` - Landing page URL

**Note:** `.env.local` uses `:` instead of `=` for variable assignment (non-standard format that works with the current setup)
- `VITE_API_URI_CONFIG` - Production API base URL
- `VITE_URL_SSO` - Keycloak SSO logout URL
- `VITE_URL_USER` - User service URL for redirects

### PWA Configuration

- Auto-update registration with `vite-plugin-pwa`
- Manifest: "HRMS-Checkin" / "HRMS Checkin"
- Icons: 192x192 and 512x512 PNG
- Service worker registered in `src/registerServiceWorker.ts`

### Import Aliases

- `@` is configured as an alias for the `src/` directory
- Use this for all imports from within the source directory

### Environment Variable Substitution (Docker)

The Docker build uses a multi-stage pattern:
1. **Build stage**: Node.js Alpine builds the static assets with `npm run build`
2. **Production stage**: nginx serves the static files
- Environment variables (`VITE_API_URI_CONFIG`, `VITE_URL_SSO`, `VITE_URL_LANDING`, `VITE_URL_USER`) are substituted at container runtime via `entrypoint.sh` using `sed`
- Built JS files contain placeholder values that get replaced with actual values at startup

### Testing Patterns

- Unit tests: `*.spec.{js,ts}` - Run with Vitest in jsdom environment
- E2E tests: `*.cy.{js,ts}` - Run with Cypress
- E2E test server runs on port 4173 (via `start-server-and-test`)

### HTTP Interceptor Behavior

- The axios interceptor in `http.ts` detects 401/403 responses but automatic logout is currently disabled (commented out)
- 401 handling is done manually in `messageError()` from the mixin store

## Development Notes

**When adding new features:**
1. Create API functions in `src/api/`
2. Define TypeScript interfaces in `src/interface/response/`
3. Use Pinia stores for complex state, composables for reusable logic
4. Follow Thai localization patterns for user-facing text
5. Ensure privacy consent flow for camera/location features

**When working with dates:**
- Always use `date2Thai()` or `convertDateToAPI()` from mixin store
- Dates stored in BE format (year + 543)
- API expects `yyyy-MM-dd` or `yyyy-MM-dd HH:mm:ss` format

**When handling errors:**
- Use `messageError()` from mixin store for consistent error dialogs
- 401 errors trigger automatic logout
- Dialog overlap prevention built into error handling

**When running tests:**
- Unit tests use Vitest with jsdom environment
- E2E tests use Cypress with baseUrl: `http://localhost:4173`
- Test files follow pattern: `*.cy.{js,ts}` or `*.spec.{js,ts}`
