I did not know about this, I'll take a look at it once I'm home. Thanks!

For anyone without the inclination to wade through 47 pages, here's what they say about HTMX, which they've classified as "Assess" rather than "Trial" or "Adopt"

htmx is a small, neat HTML UI library that recently became popular seemingly out of nowhere. During our Radar discussion, we found its predecessor intercooler.js existed ten years ago. Unlike other increasingly complex pre-compiled JavaScript/TypeScript frameworks, htmx encourages the direct use of HTML attributes to access operations such as AJAX, CSS transitions, WebSockets and Server- Sent Events. There’s nothing technically sophisticated about htmx, but its popularity recalls the simplicity of hypertext in the early days of the web. The project’s website also features some insightful (and amusing) essays on hypermedia and web development, which suggests the team behind htmx have thought carefully about its purpose and philosophy.
