## What it is
htmx is a small, dependency-free JavaScript library that lets any HTML element issue AJAX requests, WebSockets, and Server-Sent Events via HTML attributes, enabling hypermedia-driven UIs without heavy JavaScript frameworks. It is the successor to intercooler.js and works with any server that responds with HTML.

## Use cases
- add partial page updates to a server-rendered site without writing javascript
- build a hypermedia-driven web app with html responses instead of json apis
- replace react with plain html attributes for a simple crud app
- add live updates to a page via websockets or server-sent events
- poll a server endpoint and swap html fragments into the dom
- progressively enhance forms and buttons with ajax

## When to choose
- your backend renders HTML and you want interactivity without a SPA framework
- you want a tiny, dependency-free script with no build step
- you prefer HATEOAS/hypermedia architecture over client-side state management
- you need broad browser support including a maintained IE-compatible 1.x line

## When to avoid
- you need rich client-side state management, offline support, or complex SPA routing
- your API returns JSON only and you cannot serve HTML fragments
- you need fine-grained reactive UI updates typical of react/vue/svelte
