🚀 Quick Start

Option 1: Docker (Recommended)

# Clone the repository
git clone <repository-url>
cd internTask

# Start all services
docker-compose up -d

# Wait 30 seconds for database initialization
# Access the application:
# - Customer Portal: http://localhost:3000
# - Admin Dashboard: http://localhost:3000/admin/login
# - Backend API: http://localhost:5000/api

Option 2: Local Development

# Clone and install
git clone <repository-url>
cd internTask
npm run install:all

# Set up environment variables
cp .env.example .env
cd backend && cp .env backend/.env
cd ../frontend && cp .env frontend/.env

# Start MySQL (ensure it's running)
# Update backend/.env with your MySQL credentials

# Run migrations and seed data
cd backend
npm run migrate
npm run seed

# Start development servers (from root)
npm run dev

# Access:
# - Frontend: http://localhost:3000
# - Backend: http://localhost:5000

📥 Installation

Step 1: Clone Repository

git clone <repository-url>
cd internTask

Step 2: Install Dependencies

# Install all dependencies
npm run install:all

# Or install individually
npm install              # Root
cd backend && npm install
cd ../frontend && npm install

Step 3: Environment Configuration

Create .env files:

backend/.env

JWT_EXPIRES_IN=24h

CORS_ORIGIN=http://localhost:3000

frontend/.env

REACT_APP_API_URL=http://localhost:5000/api

Step 4: Database Setup

# Ensure MySQL is running
# Login to MySQL and create database (optional - migration does this)
mysql -u root -p
CREATE DATABASE service_requests_db;
EXIT;

# Run migrations
cd backend
npm run migrate

# Seed sample data

🔧 Troubleshooting

Database Connection Issues

Problem: Can't connect to MySQL

Solution:

# Check MySQL is running
systemctl status mysql   # Linux
brew services list       # macOS

# Test connection
mysql -u admin -p

# Verify credentials in backend/.env

Port Already in Use

Problem: Port 3000 or 5000 already in use

Solution:

# Find and kill process (Linux/macOS)
lsof -ti:3000 | xargs kill -9
lsof -ti:5000 | xargs kill -9

# Windows
netstat -ano | findstr :3000
taskkill /PID <PID> /F

Docker Issues

Problem: Containers won't start

Solution:

# Clean up Docker
docker-compose down -v
docker system prune -a

# Rebuild
docker-compose build --no-cache
docker-compose up -d

Migration Errors

Problem: Migration fails

Solution:

# Drop database and retry
mysql -u admin -p
DROP DATABASE service_requests_db;
EXIT;

# Re-run migration
cd backend
npm run migrate
npm run seed

Frontend Build Errors
