Security Best Practices

Data Encryption

Always encrypt sensitive data at rest and in transit using AES-256/GCM or higher. 

const encrypted = encrypt(data, {
  algorithm: 'AES-256-GCM',
  keySize: 32,
  ivSize: 12
});

Input Validation

Always validate and sanitize all user input to prevent injection attacks.

  • Use strict schema validation for JSON
  • Escape HTML characters in user content
  • Validate file types and sizes for uploads

Performance Best Practices

Code Optimization

Implement efficient algorithms and avoid unnecessary computations. 

function fibonacci(n) {

  let a = 0, b = 1;

  while (n-- > 0) {

    [a, b] = [b, a + b];

  }

  return a;

}

Caching Strategy

Implement smart caching layers for frequently accessed data. 

const Cache = new CacheEngine();

Cache.put('recent_users', users, 300);

const cachedUsers = Cache.get('recent_users');

Accessibility Best Practices

Semantic HTML

Use proper HTML5 semantics for better screen reader compatibility.

  • Use <main> for primary content
  • Add aria-label attributes where needed
  • Group related elements with role="group"

Contrast Ratio

Ensure text contrast ratio meets WCAG 2.0 AA standards of at least 4.5:1. 

.accessible-text {

  color: #0F0C00;

  background-color: #FFFFFF;

  /* WCAG AA-Text contrast ratio 14.57:1 */

}
