react is api stable, but not api stable if you know what I mean. with react, the ground is always shifting underneath you, which something like wikimedia probably don't have the resources to keep up with. even, as someone who has done react professionally, I can advise any small nimble teams, out there react ain't for ya. it don't love ya. however, for the big enterprisey apps, yeah react is good.
For the big enterprise apps “the ground is always shifting underneath you” is the worst nightmare that can be imagined. The only exception is if your corporation controls these shifts.
- facebook used to maintain CSSTransition for animation but dropped support for it and gave it to a dude who broke not only the public API but also some features I was relying on. I'm left having to recreate all the animation in a different lib, meh
- lifecycles related deprecation: componentWillMount, componentWillReceiveProps, componentWillUpdate. My app used to have a lot of these but that's the easy part to migrate, the problem comes when third party libraries use those and nobody support those anymore
- method deprecation which brake third party libraries: findDOMNode. The 2 one I've used that relied on it: dnd and csstransition. There's no clear path forward that would take less than a few days to migrate my code, meh
- upgrading webpack to whatever your config should look like in 2021 and what new plugin for x is named
Nothing very specific to react in particular but for simple use case jquery or plain javascript tends to create less problems to maintain things over longer period of time
I'm not the guy you asked but I'm guessing he's referring to the "blessed way" of doing React, which seems to change every couple of years. Class components one year, pure components the next, functional components the next. A couple of years after that you're mad if you use React without Redux, the next year you'd be crazy to do Redux. State management a year later should be done with hooks, as should everything else. So what's going to be the next piece of guidance that will make our apps perfect?
