Architecture
Server
Elysia.js on Bun. All API routes are in src/app.ts as createApp() — testable via app.handle(request) without starting a server. src/index.tsx adds Vite middleware (dev) or static serving (prod) and calls .listen(). src/serve.ts is the dev entry point (dynamic import workaround for Bun EADDRINUSE race).
Database
PostgreSQL via Prisma v6. Client generated to ./generated/prisma (gitignored — run bun run db:generate after checkout or schema changes).
Schema models: User, Session, App, Log, Bug, BugImage, BugLog
Enums: Role (ADMIN, DEVELOPER), BugStatus (OPEN, ON_HOLD, IN_PROGRESS, RESOLVED, RELEASED, CLOSED), BugSource (QC, SYSTEM, USER), LogType (CREATE, UPDATE, DELETE, LOGIN, LOGOUT)
Import the singleton: import { prisma } from './lib/db'
Auth & Roles
Session-based auth with HttpOnly cookies stored in the DB (24h expiry). Two roles: DEVELOPER (super admin) and ADMIN. Users listed in SUPER_ADMIN_EMAIL env var are auto-promoted to DEVELOPER on login.
Endpoints: POST /api/auth/login, POST /api/auth/logout, GET /api/auth/session
Auth state on the frontend is managed via useSession() / useLogin() / useLogout() in src/frontend/hooks/useAuth.ts (TanStack Query).
Frontend
React 19 + Vite 8 (middleware mode in dev). TanStack Router with file-based routing in src/frontend/routes/. All routes are wrapped in DashboardLayout from src/frontend/components/DashboardLayout.tsx.
Route structure:
/→ redirect/login→ login page/dashboard→ stats overview/apps→ app list/apps/$appId→ per-app layout with nested routes:index,errors,logs,users,villages,orders,products,payments/users→ operator management/logs→ system activity log/bug-reports→ cross-app bug reports/profile→ user profile
App configs are defined in src/frontend/config/appMenus.ts — each app has an ID and a menu list. Currently active: desa-plus. Add new app entries here to register them.
routeTree.gen.ts is auto-generated by the TanStack Router Vite plugin — never edit it manually.
UI: Mantine v8, dark theme forced (#242424). Charts use @mantine/charts (recharts under the hood). Icons from react-icons/tb.
API Structure
All API routes live in src/app.ts. Key groups:
/api/auth/*— authentication/api/dashboard/*— stats and recent errors/api/apps,/api/apps/:appId— app listing and detail/api/bugs,/api/bugs/:id/status,/api/bugs/:id/feedback— bug report CRUD/api/operators,/api/operators/:id— user management/api/logs— system activity log/api/system/status— health check with DB connectivity
Logging
createSystemLog(userId, type, message) from src/lib/logger.ts writes to the Log model. Call it for any significant user action (login/logout/CRUD). Logging errors are swallowed so they never break the main flow.
Environment Variables
Required: DATABASE_URL, GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET
Optional: PORT (default 3000), NODE_ENV, REACT_EDITOR, SUPER_ADMIN_EMAIL (comma-separated)
Validated at startup in src/lib/env.ts — missing required vars throw immediately.
