Every site I build works with JavaScript disabled. I use Next.js with server side rendering so that the initial page load is an accessible HTML document that is progressively enhanced for those with JS enabled during hydration by adding interactivity and smooth client side page transitions without full page reloads.
None of this is possible with HTMX if the user has JavaScript disabled. The first step to using HTMX is to import a JavaScript file from a CDN, and none of the features for partial page replacement will work without it. Whereas with Next.js, with JavaScript disabled, a Link will revert to a full page load where the next page is rendered on the server. It will be progressively enhanced to what appears to be a partial page load by using the same JavaScript that would render the full page on the server to instead render it on the client starting from the current state of the DOM.

Umm, progressive enhancement is a general concept that can be applied to any stack, not just Next.js. With htmx we can just use good old anchor and form tags to fall back to full-page loads if JavaScript is disabled. In fact it makes it more obvious because usually those are the tags we're using even with htmx and JavaScript enabled.
How do you do that if your backend is setup to respond to requests with partial content? You now need to make sure your backend can render both the full page and also individual components of it. That's not functionality that's provided by HTMX itself.
It's fairly easy. Htmx sends an `HX-Request: true` header with all requests. You can check for the presence of this header and have an if/else in your handler to render a partial or a full page. Or if you want to enable caching you can configure the `Accept` header with a customized content type like `text/html;hx=1`. That way you can set a response header `Vary: Accept` to ensure that caching is correct.
