🚀 Quick Start

Prerequisites

• Node.js (v18+ recommended)
• MongoDB connection string
• Git

1. Clone and Setup

git clone [your-repo-url]
cd inventor

2. Backend Setup

cd backend
npm install

# Create .env file
echo "MONGODB_URI=your_mongodb_connection_string_here" > .env
echo "PORT=3000" >> .env

# Start backend server
npm run dev

3. Frontend Setup

cd ../frontend
npm install

# Start frontend development server
npm run dev

4. Open Your Browser

• Frontend: http://localhost:5173
• Backend API: http://localhost:3000
