# CLAUDE.md

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

## Commands

```bash
# Development
bun install                  # Install dependencies
bun run dev                  # Dev server with experimental HTTPS (localhost:3000)
bun run build                # Production build
bun run start                # Start production server
bun run lint                 # Run ESLint

# Database
npx prisma migrate dev       # Run/create migrations
npx prisma db seed           # Seed with initial data
npx prisma generate          # Regenerate Prisma client after schema changes
```

## Architecture

**Sistem Desa Mandiri** is a village administration platform built on Next.js 14 (App Router) with PostgreSQL.

### Key Layers

- **`src/app/(application)/`** — Auth-protected pages grouped by feature (announcement, division, project, discussion, member, profile, home, group)
- **`src/app/(auth)/`** — Login/register pages
- **`src/app/api/`** — REST API endpoints; subdirectories map to resource types (`/api/announcement`, `/api/project`, `/api/task`, etc.). Mobile-specific endpoints live under `/api/mobile/`
- **`src/module/`** — Business logic modules, one per feature (19 modules). Each module contains hooks, components, and API call functions for that domain
- **`src/lib/`** — Shared utilities: Prisma client singleton (`prisma.ts`), Firebase init, route definitions (`routes.ts`), push notification hooks

### Data Access Pattern

All DB access goes through the Prisma client singleton in `src/lib/prisma.ts`. Prisma schema is at `prisma/schema.prisma` (40+ models). Migrations live in `prisma/migrations/`.

### State Management

- **Hookstate** (`@hookstate/core` + `@hookstate/localstored`) for client-side global state with localStorage persistence
- **Iron-session** for server-side session management / auth
- **Jose** for JWT handling

### UI Stack

- **Mantine 7** is the primary UI library (components, forms, modals, notifications, charts, dates, etc.)
- **Tailwind CSS** for utility classes — used alongside Mantine
- **PostCSS** configured with Mantine preset (`postcss.config.mjs`)

### Real-time & Notifications

- **Firebase FCM** (`src/lib/firebase/`) for mobile push notifications
- **Web Push + VAPID keys** (`src/lib/usePushNotifications.ts`) for browser push
- **wibu-realtime** (custom library) for WebSocket-based real-time updates

### User Roles

Five roles with distinct access levels (see `PANDUAN PENGGUNAAN.md`):
1. **Super Admin** — full system access
2. **Admin Desa** — village-level administration
3. **Ketua Divisi** — division leader
4. **Anggota Divisi** — division member
5. **Warga/Perangkat Desa** — village resident/official

## Environment Variables

Copy `.env.example` to `.env`. Required variables:

| Variable | Purpose |
|---|---|
| `DATABASE_URL` | PostgreSQL connection string |
| `GOOGLE_PROJECT_ID`, `GOOGLE_CLIENT_EMAIL`, `GOOGLE_PRIVATE_KEY` | Firebase Admin SDK (FCM) |
| `NEXT_PUBLIC_VAPID_PUBLIC_KEY`, `VAPID_PRIVATE_KEY` | Web Push |
| `WS_APIKEY` | WebSocket/file storage API key |
| `WIBU_REALTIME_KEY` | Real-time communication |
| `FCM_KEY` | Firebase Cloud Messaging |

## Deployment

Docker images are built via `.github/workflows/publish.yml` and pushed to GHCR (`ghcr.io`). Portainer redeploys via `.github/workflows/re-pull.yml`. Supports `dev`, `stg`, and `prod` stacks.

The Dockerfile uses a two-stage build: Bun builder → Bun runner (non-root user, port 3000).
