πŸš€ Quick Start Guide

πŸ“‹ Prerequisites

Before you begin, ensure you have the following installed:

  • Node.js 18.0+ (Download here)
  • npm or yarn package manager
  • MongoDB (Local installation or MongoDB Atlas account)
  • Git for version control

πŸ”§ Installation Steps

1. Clone the Repository

# Clone the repository
git clone https://github.com/siddharthharshraj/QuickPe.git
cd QuickPe

# Check the project structure
ls -la

2. Install Dependencies

# Install root dependencies
npm install

# Install frontend dependencies
cd frontend
npm install

# Install backend dependencies
cd ../backend
npm install

# Return to root directory
cd ..

3. Environment Configuration

Backend Environment Setup:

Create .env file in the backend/ directory:

# Database Configuration
MONGODB_URI=mongodb://localhost:27017/quickpe
# For MongoDB Atlas: mongodb+srv://username:[email protected]/quickpe

# JWT Configuration
JWT_SECRET=your_super_secure_jwt_secret_key_minimum_32_characters_long
JWT_EXPIRES_IN=7d

# Server Configuration
NODE_ENV=development
PORT=5001

# Email Configuration (Optional - for contact form)
GMAIL_USER=[email protected]
GMAIL_APP_PASSWORD=your_16_character_app_password

# Security Configuration
BCRYPT_SALT_ROUNDS=12
RATE_LIMIT_WINDOW_MS=900000
RATE_LIMIT_MAX_REQUESTS=100

# CORS Configuration
CORS_ORIGIN=http://localhost:5173

Frontend Environment Setup:

Create .env file in the frontend/ directory:

# API Configuration
VITE_API_BASE_URL=http://localhost:5001/api/v1
VITE_SOCKET_URL=http://localhost:5001
