Yep, my day job is working on the Replay time-traveling debugger for JS ( https://replay.io/ ). Also saw someone post an indie gaming company's TTD development environment yesterday: https://www.reddit.com&#

The article isn't _wrong_ - React, Redux, and Next are all still the leaders in their respective categories. (And I say that as the maintainer of Redux and someone who's active in the React community.) But it's also worth no

Oh hey, I just wrote this page yesterday :) Redux usage has changed dramatically since 2019 thanks to Redux Toolkit + React-Redux hooks, and we get feedback on a daily basis from folks telling us how much they enjoy using it. But, a lot of

FYI, we recommend that most folks should not write promise management, data fetching, or loading status tracking code directly If you're using just React, use React Query or something like `react-async`. If you're using Redux, use

Flow is effectively dead. Yeah, there's still a team at Facebook developing it, but they've made it clear they don't care about any use cases or requests other than Facebook's own internal needs. TS won, and the ecosyste

It's been only loosely maintained over the last couple years. Also, despite the `facebook` org, as far as I know the last couple maintainers were not actually Facebook employees. See this discussion thread from a couple years ago: ht

Great investigation work and excellent writeup! Out of curiosity: did anyone end up filing issues or PRs against these tools as a result of either of your articles?

I sorta see what you're saying, in that `foo` wasn't passed into this function as an argument. But I do still think this is a general misconception of how React works. Every React component, whether it's written as a class c

Hi, I'm a Redux maintainer. This is a good post, but I'm a bit surprised it doesn't talk about memoized selector functions at all. We specifically teach those as a way to improve performance, by avoiding costly transformatio

Say you have `<Parent>` and `<Child>`, and `<Child>` is outputting several HTML elements when it renders. There's three major aspects that control what happens to the DOM nodes that React created for `<Child>`:

> "not documented what the process is" It's fairly straightforward. React uses a module-scoped variable, assigns to it when it starts rendering a component, and nulls it out when it's done rendering the component. An

I recently built our React DevTools support for Chromium. I used our time-travel debugging backend to inject the RDT logic into the paused browser at every React commit to extract the tree operations data. This post covers how the React Dev

Hey, that's pretty neat! I'm a Redux maintainer, and it's always great to see people building things with Redux Toolkit / RTK Query. Congrats!

FWIW, Redux literally _is_ a pub-sub/observer pattern implementation :) And the Redux core library _is_ extremely small. But, that led to the community building hundreds of addon libraries for the same sets of use cases, which is what

Redux is still by _far_ the most widely used state management library in React apps. By my estimates, around 35-40% of all React apps use Redux, and that's far more than any other state library in the ecosystem: - https://b

Hi, I'm a Redux maintainer. I'll definitely agree that Redux _has_ been overused. But it's also worth understanding _why_ Redux was created in the first place and why it got so popular. As a brief recap: the first major wave

I would definitely disagree with "Redux is out of fashion". Redux is still by far the most widely used state management lib with React apps, by a very large margin - my estimates are that 35-40% of React apps use Redux, and no ot

Huh. As the current Redux maintainer, I'm not sure if I'm impressed or horrified at this :) (now I'm curious how well it would handle requests using our modern Redux Toolkit API syntax...)

The usual misunderstandings about context are: - Thinking that if you change a field in the context value only components that read that field will re-render - Thinking that _only_ the components that consume the context will re-render, not

Sure. I just spent a few minutes poking back through the other weather apps I've got installed on my phone to see how their radar maps look. The two I like best are Windy and Ventusky. Both feel pretty readable in terms of background l

Calling `setState` while rendering has been a legitimate thing to do since hooks first came out, but _only_ in one specific scenario / usage pattern. From the original hooks FAQ at time of release: - https://reactjs.org&#x2F

Just to check, are you using "modern Redux" with Redux Toolkit + React-Redux hooks, or the older-style legacy "handwritten" Redux patterns that existed before Redux Toolkit? If you haven't seen RTK, we designed it t

I'm genuinely curious - do you have any examples of "misusing `createSlice`"? FWIW I see folks misusing / misunderstanding Context on a near-daily basis, mostly around misunderstanding what components will re-render and

Absolutely, and that's a major reason why we specifically teach the React-Redux hooks API as default today, and have guidance on setting up "pre-typed" hooks with the store types baked in: - https://redux.js.org&#x
