You have to learn something. You can claim bloat in JS frameworks, but that isn’t solved by simply moving it to the server.
Is htmx lean and nice today? Probably! But does it handle the same use cases that the React users have? What happens to it under pressure of feature bloat? Small-core frameworks like Elm who resisted this pressure were abandoned by big shops. You can’t just take something immature (however good) and simply extrapolate a happy future.
> Tooling is an ever-shifting landscape in terms of building and packaging code.
Yes. JS is not the only language with churn issues and dependency hell.
> Managing state on both the client and server
Correct me if I’m wrong, but state can change for something outside of a htmx request, meaning you can end up with stale state in element Y in the client after refreshing element X. The difference is that your local cache is in the DOM tree instead of a JS object.
> By their nature, a fat client requires the client to execute a lot of JavaScript. If you have modern hardware, this is fine, but these applications will be unusable & slow for those on older hardware or in locations with slow and unreliable internet connections.
On unreliable connections you want as thick of a client as possible. If you have server-in-the-loop for UI updates, you quite obviously have latency/retry issues. It’s much preferable to show stale state immediately and update in the background.
> It is very easy to make an SPA incorrectly, where you need to use the right approach with hooks to avoid ending up with abysmal client-side performance.
Bloat comes from reckless software development practices, and are possible in any technology. Angular and React have a shitton of features and ecosystem around it, whereas say Svelte is more lean. Enterprisey shops tend to prioritize features and not give a flying fuck about performance. This is a business choice, not a statement about technology.
> Some SPA implementations of SPA throw away progressive enhancement (a notable and noble exception is Remix). Therefore, you must have JavaScript turned on for most SPAs.
Finally, we cut to the chase. This is 100% true, and we should be talking about this, because it’s still not settled: do we want web pages or web apps? If both, where is the line? Can you expect something like Slack to work without JavaScript? What about a blog with interactive graphs? Should everything degrade or should some things require JS/WASM?
I love that htmx exists. I have absolutely nothing against it. It honors some of the early web philosophy in an elegant and simple manner. It may be a better model for server-centric apps and pages, which don’t need offline or snappy UIs. But it cannot magically solve the inherent complexities of many modern web apps.
