Mostly things that are very widely used in industry are indeed no longer “in fashion”. Instead they were in fashion and actually proved valuable enough to have staying power (as opposed to most fashionable things that are junk). Charitably, anyway — sometimes it seems you can’t tell why something is still widely used.

Probably the mentioned hooks-based approaches are indeed fashionable now. Remains to be seen whether they’ll stick around.

My team at work has completely rewritten from Redux with Redux Form to Tanstack query and React Hook Form over the past two years, and we don’t miss a single thing about Redux.

We make an app that contacts lots of microservices in sequence and combines the data in many ways. Having automatic refetching, caching and the like by default makes a world of difference.

This is not fashion. It’s quality.

I don't know if it's still the case but when I started my career (granted, some decades ago) using the new hotness X/Motif + C++, there were still more lines of COBOL around than anything else. (Hell, might not have been the case then, but that was the yarn.)

RTK Query is an excellent package! Coming from the React Query world, I inherited an RTK Query project and was initially disappointed, but have come to prefer it over (the also excellent) React Query.
