It seems much of modern web development is structured around having a JavaScript program on the front-end (browser) which exchanges data encoded in JSON asynchronously with the back-end servers. htmx uses a novel (or throwback) approach: it asynchronously fetches snippets of HTML from the back-end, and splices the results into the live page. For example, a htmx-powered button may request a URI on the server, receive HTML in response, and then the button itself would be replaced by the resulting HTML, within the page.

I experimented with incorporating it into an existing, old-school CGI web app: IkiWiki, which I became a co-maintainer of this year, and powers my blog. Throughout this project I referred to the excellent book Server-Driven Web Apps with htmx.
