npm install

# Start development server
npm start

The application will be available at http://localhost:3000

Database Initialization

The app automatically seeds the database with:

• 25 job postings across different departments
• 1000+ candidates with realistic names and data
• 3+ assessment templates with multiple question types
• Timeline events and candidate relationships

🎯 Technical Highlights

Performance Optimizations

• Virtualized Lists for large candidate datasets
• Optimistic Updates for instant UI feedback
• Lazy Loading for route-based code splitting
• Memoized Components to prevent unnecessary re-renders

User Experience

• Realistic API Simulation with latency and error rates
• Progressive Enhancement with offline capabilities
• Responsive Design across all device sizes
• Accessibility with proper ARIA labels and keyboard navigation

Code Quality

• TypeScript-Ready structure with JSDoc comments
• Consistent Patterns across all components
• Error Boundaries for graceful failure handling
• Comprehensive Testing setup ready

🔧 Development Guidelines

Environment Setup

1. Install recommended VS Code extensions:
   • ESLint
   • Prettier
   • Tailwind CSS IntelliSense
2. Use Node.js version 16 or higher
3. Enable ESLint and Prettier in your editor

Project Configuration

1. Environment Variables (create .env file):

REACT_APP_API_URL=http://localhost:3000
REACT_APP_ENV=development

2. Configure MSW for API mocking:

// In src/mocks/browser.js
import { setupWorker } from 'msw'
import { handlers } from './handlers'
export const worker = setupWorker(...handlers)

Adding New Features

1. Create components in appropriate directories
2. Use established patterns for forms and API calls
3. Follow the existing naming conventions
4. Add proper error handling and loading states
5. Update seed data if needed

Code Style Guide

1. Use functional components with hooks
2. Implement proper TypeScript types/interfaces
3. Follow Airbnb JavaScript Style Guide
4. Write JSDoc comments for functions
5. Create unit tests for new features

Database Operations

// Use DatabaseService for all operations
import { DatabaseService } from '../services/database';

// Create
const job = await DatabaseService.createJob(data);

// Read
const jobs = await DatabaseService.getJobs(filters);

// Update
const updated = await DatabaseService.updateJob(id, changes);

// Delete
await DatabaseService.deleteJob(id);

API Integration

// Use MSW handlers for API simulation
import { rest } from 'msw';

// Add new endpoints to handlers.js
export const newHandlers = [
  rest.get('/api/new-endpoint', async (req, res, ctx) => {
    // Implementation
  }),
];
