📈 Performance Optimization Tips

Image Optimization

# Convert PNG to WebP
cwebp input.png -o output.webp

# Or use ImageMagick
convert image.png -quality 80 image.webp

Bundle Analysis

npm install -D vite-plugin-visualizer
# Analyze bundle size after build

Monitoring in Production

// Use Web Vitals API
import { getCLS, getFID, getFCP, getLCP, getTTFB } from 'web-vitals';
getCLS(console.log);
getFID(console.log);

---

🧪 Testing Strategy

Unit Testing (Ready for Jest)

// Example test structure
import { render, screen } from '@testing-library/react';
import Button from './Button';

describe('Button', () => {
  it('renders with text', () => {
    render(<Button>Click me</Button>);
    expect(screen.getByText('Click me')).toBeInTheDocument();
  });
});

E2E Testing (Playwright/Cypress Ready)

describe('Portfolio Navigation', () => {
  it('should scroll to projects on click', () => {
    cy.visit('/');
    cy.get('[data-testid="projects-link"]').click();
    cy.get('#projects').should('be.visible');
  });
});
