# Setup Instructions
## Prerequisites
1. **Node.js 18+** - [Download](https://nodejs.org/)
2. **pnpm 8+** - Install with: `npm install -g pnpm`
3. **PostgreSQL 14+** - Either:
- Install locally: [PostgreSQL Downloads](https://www.postgresql.org/download/)
- Use Docker: `docker-compose up -d postgres`
4. **Redis** - Either:
- Install locally: [Redis Downloads](https://redis.io/download)
- Use Docker: `docker-compose up -d redis`
## Quick Start
### Option 1: Using Docker (Recommended)
If you have Docker and Docker Compose installed:
```bash
# 1. Start all services (PostgreSQL + Redis)
docker-compose up -d
# 2. Install dependencies
pnpm install
# 3. Generate Prisma client
pnpm db:generate
# 4. Run database migrations
pnpm db:migrate
# 5. (Optional) Seed the database
pnpm db:seed
# 6. Start development servers
pnpm dev
```
### Option 2: Local Services
If you prefer to run PostgreSQL and Redis locally:
1. **Install and start PostgreSQL:**
```bash
# Ubuntu/Debian
sudo apt-get install postgresql postgresql-contrib
sudo systemctl start postgresql
# Create database
sudo -u postgres psql
CREATE DATABASE aseret_bank;
CREATE USER aseret_user WITH PASSWORD 'aseret_password';
GRANT ALL PRIVILEGES ON DATABASE aseret_bank TO aseret_user;
\q
```
2. **Install and start Redis:**
```bash
# Ubuntu/Debian
sudo apt-get install redis-server
sudo systemctl start redis-server
```
3. **Configure environment:**
```bash
cp .env.example .env
# Edit .env with your database credentials
```
4. **Install dependencies and setup:**
```bash
pnpm install
pnpm db:generate
pnpm db:migrate
pnpm db:seed
pnpm dev
```
## Environment Variables
Copy `.env.example` to `.env` and configure:
```bash
cp .env.example .env
```
Key variables to set:
- `DATABASE_URL` - PostgreSQL connection string
- `REDIS_URL` - Redis connection string
- `JWT_SECRET` - Secret for JWT tokens (generate a strong random string)
- `JWT_REFRESH_SECRET` - Secret for refresh tokens
- `FRONTEND_URL` - Frontend URL (default: http://localhost:3000)
- `PORT` - Backend port (default: 3001)
## Database Setup
### Initial Migration
```bash
pnpm db:migrate
```
This will:
- Create all database tables
- Set up relationships
- Create indexes
### Seed Data
```bash
pnpm db:seed
```
This creates:
- Admin user: `admin@aseret.com` / `admin123`
- Loan Officer: `officer@aseret.com` / `officer123`
- Sample Customer: `customer@example.com` / `customer123`
### Prisma Studio
View and edit database data:
```bash
pnpm db:studio
```
Opens at: http://localhost:5555
## Development
### Start Both Servers
```bash
pnpm dev
```
- Backend: http://localhost:3001
- Frontend: http://localhost:3000
- API Docs: http://localhost:3001/api-docs
### Start Separately
```bash
# Backend only
pnpm dev:backend
# Frontend only
pnpm dev:frontend
```
## Troubleshooting
### Database Connection Issues
1. Verify PostgreSQL is running:
```bash
sudo systemctl status postgresql
# or
docker-compose ps
```
2. Test connection:
```bash
psql -h localhost -U aseret_user -d aseret_bank
```
3. Check DATABASE_URL in `.env` matches your setup
### Redis Connection Issues
1. Verify Redis is running:
```bash
redis-cli ping
# Should return: PONG
```
2. Check REDIS_URL in `.env`
### Port Already in Use
If ports 3000 or 3001 are already in use:
1. Find the process:
```bash
lsof -i :3001
```
2. Kill the process or change PORT in `.env`
### Prisma Client Not Generated
```bash
cd backend
pnpm prisma:generate
```
## Production Build
```bash
# Build
pnpm build
# Start
pnpm start
```
