🚀 Quick Start

Option 1: Docker (Recommended)

Prerequisites:

• Docker 20.10+
• Docker Compose 2.0+
• PostgreSQL 15+ (external)
• Redis 7+ (external)

# 1. Setup environment
cp .env.example .env
# Edit .env dengan konfigurasi PostgreSQL dan Redis Anda

# 2. Run migration (one-time)
cd backend
bun install
bun run migrate
cd ..

# 3. Start services
docker-compose up -d

# 4. Access application
# Frontend: http://localhost
# Backend: http://localhost:3000

Using Makefile:

make build    # Build images
make up       # Start services
make logs     # View logs
make down     # Stop services

Lihat DOCKER.md untuk dokumentasi lengkap Docker.

Option 2: Manual Setup

Prerequisites:

• Bun (untuk backend)
• Node.js 18+ (untuk frontend)
• PostgreSQL 15+
• Redis 7+

1. Setup Backend

# Navigate to backend
cd backend

# Install dependencies
bun install

# Setup environment
cp .env.example .env
# Edit .env dengan konfigurasi database Anda

# Create database
psql -U postgres -c "CREATE DATABASE gprx;"

# Run migration
bun run migrate

# Seed sample data
bun run seed

# Start backend
bun run dev

Backend akan running di http://localhost:3000

2. Setup Frontend

# Navigate to frontend
cd frontend

# Install dependencies
npm install

# Setup environment
cp .env.example .env

# Start frontend
npm run dev

Frontend akan running di http://localhost:5173

3. Login

Buka browser dan akses http://localhost:5173

Default credentials:

Username: admin
Password: admin123

📦 Production Deployment

Backend

1. Set NODE_ENV=production
2. Use strong JWT_SECRET
3. Generate secure SERVER_KEY_ENCRYPTION_KEY
4. Configure proper CORS_ORIGIN
5. Use strong database passwords
6. Enable PostgreSQL SSL
7. Enable Redis password
8. Setup database backups
9. Use process manager (PM2/systemd)
10. Setup reverse proxy (nginx)

Frontend

1. Build: npm run build
2. Upload dist/ folder to static hosting
3. Configure VITE_API_URL to production backend
4. Setup CDN (optional)
5. Enable HTTPS

🐛 Troubleshooting

Backend Issues

Connection Error ke PostgreSQL

# Check PostgreSQL status
sudo systemctl status postgresql

# Start PostgreSQL
sudo systemctl start postgresql

Connection Error ke Redis

# Check Redis status
sudo systemctl status redis

# Start Redis
sudo systemctl start redis

Frontend Issues

CORS Error

• Pastikan backend CORS_ORIGIN sesuai dengan frontend URL
• Restart backend setelah mengubah CORS

Cannot Connect to Backend

• Pastikan backend running di http://localhost:3000
• Check VITE_API_URL di frontend .env

Login Failed

• Pastikan backend sudah di-seed
• Check credentials: admin / admin123
