Best Practices

PWA Excellence Checklist

Best practices में शामिल हैं: हमेशा HTTPS, responsive design, fast load times (3s से कम), clear install prompts, proper error handling, accessibility और comprehensive testing।

Progressive Enhancement Patterns

Progressive enhancement के साथ build करें: JavaScript के बिना core functionality काम करती है।

<!-- Fallback for no JS -->
<noscript>This app requires JavaScript. Please enable it.</noscript>

<!-- Base functionality with forms -->
<form method="POST" action="/api/save">
  <input type="text" name="task" required>
  <button type="submit">Save</button>
</form>

<!-- Enhanced with JS/PWA -->
<script>
  document.querySelector('form').addEventListener('submit', async e => {
    e.preventDefault();
    // Use PWA features: offline sync, IndexedDB, etc.
  });
</script>

Output:

App works without JavaScript and enhanced with PWA features when available.

एक आम गलती

कभी assume न करें कि PWA features उपलब्ध हैं। उन्हें use करने से पहले हमेशा feature detection के साथ check करें (if ('serviceWorker' in navigator))।
