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
