#ajax

Implement progressive enhancement with htmx. Pattern: 1. Server-rendered HTML with hx-get attributes. 2. Partial page updates without full reload. 3. hx-trigger for various events (click, scroll, intersect). 4. hx-swap strategies (innerHTML, outerHTML, beforeend). 5. Loading indicators with hx-indicator. 6. Form validation with server-side logic. 7. WebSocket updates with hx-ws. 8. Graceful fallback for no-JS scenarios. Use with Express or Django for HTML-over-the-wire architecture.
