htmx is a lightweight JavaScript library that lets you perform AJAX, CSS transitions, WebSockets, and Server‑Sent Events directly from HTML attributes. It enables hypermedia‑driven UI updates without writing custom JavaScript.

Use cases

• Add AJAX form submission to a page using only HTML attributes.
• Swap parts of a page when a button is clicked without writing JavaScript.
• Implement real‑time updates via WebSockets or SSE using declarative markup.
• Create progressive enhancement for existing server‑rendered HTML.
• Replace a full page reload with partial HTML updates triggered by any DOM event.

When to choose

• You want minimal JavaScript and prefer declarative HTML for interactivity.
• Your application is server‑rendered and you need progressive enhancement.
• You need a small, dependency‑free solution for AJAX, WebSockets, or SSE.
• You value hypermedia‑driven design and want to keep the client side simple.

When to avoid

• You require a full‑featured SPA framework with complex state management.
• Your project relies heavily on client‑side routing, component libraries, or build pipelines.
• You need extensive tooling, type safety, or a large ecosystem of UI components.
