HRIS

HRIS Production-Ready (Fullstack)

Upgrade dari aplikasi frontend-only menjadi HRIS fullstack dengan arsitektur modular, security hardening, persistence PostgreSQL, Redis cache/session, dan audit trail lengkap.

2) Database Schema (Prisma)

Tabel inti yang tersedia:

• users
• employees
• attendance
• payroll
• leave_requests
• departments
• roles
• permissions
• activity_logs
• sessions
• company_settings

activity_logs menyimpan:

• action, module, description
• metadata JSON (before/after)
• ip_address, user_agent
• created_at

3) Backend API

Endpoint utama:

• POST /auth/login, POST /auth/refresh, POST /auth/logout
• GET/POST/PUT/DELETE /employees
• GET /attendance, POST /attendance/checkin
• GET /payroll, POST /payroll/process
• GET/POST /leave-requests, POST /leave-requests/:id/approve|reject
• GET /activity-logs
• GET/PUT /settings/company-profile

4) Integrasi Frontend

Frontend React + Vite menggunakan:

• Zustand untuk auth state
• Axios client dengan Bearer token interceptor
• Halaman login, dashboard, employee management, dan audit log
• Debounce search pada halaman employees

5) Security yang Diimplementasikan

• Helmet + CORS policy ketat
• JWT access + refresh token
• Session persistence di DB
• Bcrypt password hash
• Rate limiting endpoint login
• Account lockout setelah 5 kali gagal login
• RBAC permission middleware
• Input validation via Zod
• ORM Prisma untuk SQL injection defense
• Structured logging via Pino

6) Activity Log Middleware

activityLogger middleware otomatis mencatat event penting (AUTH/HR/SYSTEM) ke tabel activity_logs dengan metadata JSON. Mendukung snapshot before/after untuk aksi update/delete/approve/reject.

7) Deployment (Docker)

Local

1. Copy env:
   • cp backend/.env.example backend/.env
2. Jalankan:
   • docker compose up --build
3. Aplikasi tersedia:
   • Frontend: http://localhost:5173
   • Backend: http://localhost:4000

Production Notes (VPS/AWS/GCP)

• Gunakan managed PostgreSQL + Redis (RDS/Cloud SQL + ElastiCache/Memorystore).
• Terminate HTTPS di reverse proxy (Nginx/Traefik/ALB).
• Simpan secrets di Vault/SSM/Secret Manager.
• Jalankan Prisma migration di CI/CD sebelum rolling update.
• Aktifkan observability (OpenTelemetry, centralized logs, metrics, alerting).

8) Security Audit Simulation (Pentest Mindset)

Risiko dan mitigasi:

• Credential stuffing → rate limit + lockout + MFA (next step).
• Token theft → short access token + rotation refresh token + secure cookie mode.
• Privilege escalation → centralized permission checks + audit logs perubahan role.
• Injection/XSS → input validation + output escaping + CSP header tambahan.
• Data exfiltration → row-level access policy + encryption at rest & in transit.

9) Bottleneck Performance Analysis

Potensi bottleneck:

• Query dashboard aggregasi payroll/attendance besar.
• List activity logs tanpa index/filter bisa lambat.
• Endpoint employee search full scan.

Rekomendasi CTO:

• Tambah index query-hot (employeeCode, module+createdAt, status+date).
• Redis caching untuk dashboard summary.
• Background job queue (BullMQ) untuk payroll batch processing.
• Read replica untuk report query berat.
