Ask HN: Can the React 19 hooks be found in the wild?
4•zwilderrr•8mo ago
Wondering if anyone is actually using useActionState, useTransition, useOptimistic, etc, in the wild, or if they are still relying on form libraries and data fetching frameworks. If yes, please indicate what (size) company you work for.

The systems I work on at work use a Java based back end and we're not going to complicate our back end more by adding a node.js sever so we can SSR, I know a lot of those hooks have to do with that. I have a bunch of demos that do graphics-heavy stuff with three.js, AFrame and such and if I publish these to the web one big advantage is I can upload them to S3 and publish them to a CDN and be done except for paying the bills, so again, no SSR. [1]
It's not so clear to me if useTransition, useOptimistic are part of the problem or part of the solution. (e.g. "looking responsive" could be the enemy of "being responsive", right now I am fixing a ticket about an incorrect state that flashes for < 0.5 sec that drives some people crazy, if I wanted something different in my framework it would be "update the UI state once, it renders once and doesn't keep calling effects and setters for an indefinite time")
Funny I am advocating for a React 19 update because at least React 19 can tell the test framework when it is done running callbacks, it might have me writing tests for components again.
[1] ... and if I want to SSR I might just ditch React and build the kind of apps that I built in 1999 with maybe a little help from HTMX

useActionState (which had questionable design to begin with) was botched right before 19 release by nextjs devs. bug reports are all "left on read".
edit: it's also a great source of laughs if you enjoy AI hallucinations. eg. ask it to generate a use action state solution which updates a select element.
