🚀 Quick Start

Prerequisites

• Node.js 18+
• MongoDB 5.0+
• SSL certificates (for production)

Installation

1. Clone the repository:

git clone https://github.com/your-org/mod-hearing-help.git
cd mod-hearing-help

2. Install dependencies:

# Backend
cd backend
npm install

# Frontend
cd ../frontend
npm install

3. Configure environment:

cd ../backend
cp .env.example .env
# Edit .env with your configuration

4. Generate secure keys:

# Generate JWT secret
node -e "console.log('JWT_SECRET=' + require('crypto').randomBytes(32).toString('hex'))"

# Generate encryption key
node -e "console.log('ENCRYPTION_KEY=' + require('crypto').randomBytes(32).toString('hex'))"

5. Start development servers:

# Backend (Terminal 1)
cd backend
npm run dev

# Frontend (Terminal 2)
cd frontend
npm start
