📦 Prerequisites

Before you begin, ensure you have the following installed:

Node.js >= 20.0.0 (Download)
npm >= 9.0.0 (comes with Node.js)
Git (Download)

Optional (for future phases):

Docker >= 24.0.0
Docker Compose >= 2.20.0
kubectl (Kubernetes CLI)

🚀 Quick Start

1. Clone the repository

git clone https://github.com/yourusername/production-api-framework.git
cd production-api-framework

2. Install dependencies

npm install

3. Set up environment variables

cp .env.example .env

Edit .env file with your configuration (defaults work for development).

4. Start development server

npm run dev

The server will start at http://localhost:3000

5. Set up databases (Phase 2)

Using Docker Compose (Recommended):

# Start PostgreSQL and Redis
docker-compose up -d

# Run database migrations
npm run migration:run

# Seed development data
npm run seed

Manual Setup:

# Install PostgreSQL 15 and Redis 7
# Update .env with your database credentials

# Run migrations
npm run migration:run

# Seed development data
npm run seed

6. Verify the server is running

Open your browser or use curl:

# Health check
curl http://localhost:3000/health

# Readiness check (includes database/Redis status)
curl http://localhost:3000/ready

# API info
curl http://localhost:3000/api/v1

# Create a test user (Phase 2)
curl -X POST http://localhost:3000/api/v1/users \
  -H "Content-Type: application/json" \
  -d '{
    "email": "test@example.com",
    "password": "SecurePass123!",
    "firstName": "Test",
    "lastName": "User"
  }'

Default Credentials (after seeding):

Email: admin@example.com
Password: Password123!
