overreacted.io VS redux

He's a React maintainer. He has a blog and a Twitter account which gained him quite some fame in the JavaScript world.

https://overreacted.io/

This is a whole thread (not a single tweet). Unfortunately Elon Musk's Twitter no longer shows threads to logged out users. :(

For convenience, I'll copy and paste the entire thread here:

1. i feel bittersweet sharing i’m leaving my job at meta in a few weeks. working in the react org at meta has been an honor. i am thankful to my past and present colleagues for taking me in, letting me make mistakes, helping me see my strengths, being kind, and sharing their time.

2. for the past three years, i kept saying i’d leave “in a year or so” but the moment never felt right. i wanted to (1) finish the new docs and (2) see a broadly usable Suspense data fetching integration shipping. after years of work from the team, both have shipped this spring.

3. i felt hesitant leaving earlier because not too long ago, leaving meta used to mean leaving the react team. that would feel too sad for me. but it is not true anymore. react has become a multi-company project, and there are several independent engineers on the team too.

4. i am staying on the react team as an independent engineer, similar to @sophiebits and @sebsilbermann . this means that i will not be actively sponsored to work full-time on react by any company, but i will stay involved in the team’s work and attend our meetings.

5. the exact nature of my future involvement is not yet clear to me. when i started on the react team seven years ago, i used to mostly write code. however, my teammates often outshine me at that, and i found myself gravitating to doing other things over time.

6. one of the things i naturally gravitated towards was explaining things. i practiced writing on http://overreacted.io, and later @rachelnabors inspired me to write http://react.dev together. i poured my heart into that project, but i bit off a bit more than i could chew.

7. what happened is that my standard for writing has gone higher but my writing ability did not. i find it difficult to write now because i can’t match the standard in my own head anymore. this will probably go away with time, but i need a little break from writing words.

8. sometimes people think i write a lot of code for react, but i haven’t been doing that for a while. aside from co-writing the new docs, the rest of my contributions in the past few years have mostly been community glue work: being a bridge between the community and the team.

9. although i enjoy this type of work, it is not sustainable to do on my own, and it has taken a toll emotionally. at some point being a single point of failure stops being fun, and i was feeling that i’m failing both the team and the community. we needed to learn to scale it up.

10. over the last year, we’ve been building a new wing of the react team focused on community glue work. i trust @Eli_White @kmiddleton14 @lunaleaps @mattcarrollcode @rickhanlonii to carry this torch in a sustainable way. i will stay very closely involved. https://twitter.com/dan_abramov/status/1644373027692462086

11. on the engineering side, i fully trust @en_JS technical leadership at Meta and @sebmarkbage technical leadership at Vercel. currently, only two companies are sponsoring employees to work full-time on React, but we’d like to onboard contributors from other companies in the future.

12. finally, a little personal note. this is not a part of some kind of a grand plan. i don’t do “plans” and “goals”. i just had a hunch that now that the things i care about are not going to fall on the floor, it’s the right moment to try something new and feel like a beginner again

13. idk what i’ll do next yet. might do some youtube, some consulting. i do feel a bit itchy to write some product code in react with a fast iteration cycle outside of a large company. maybe i’ll do a combination of all of that. i kinda want to just do nothing too. we’ll see :)

14. i feel a little relieved, a little scared, but mostly thankful. i’m grateful to @jingc for noticing me, @tomocchino for believing in me, and @sebmarkbage & @sophiebits for teaching me everything. work is people, and you’re the best i could hope for. see y’all at the weekly syncs!

Also, Dan Abramov's blog is a must-read, if you haven't yet: https://overreacted.io/

In 2015 Dan Abramov published an article titled Presentational and Container Components.

Also, Dan Abramov's blog is must read, he's literally in React team, so both React patterns, and big tech best practices: https://overreacted.io/. A bit abandoned now, but still very useful.

https://overreacted.io/ - by far the best in my opinion. Doesn’t get much more in depth than Dan

Redux

redux - Redux is a key tool used in managing state across an application. This can be used with any web technology including React, Vue and Angular docs

Redux is a client-state library.

react-redux: A powerhouse for efficient state management and data flow control. Learn more

Reducer-based: requires dispatching actions to update a big centralised state, often called a “single source of truth”. In this group, we have Redux and Zustand.

I am _thrilled_ to announce that:

Redux Toolkit 2.0 is LIVE!!!

- https://github.com/reduxjs/redux-toolkit/releases/tag/v2.0.0

This major version has new features, faster perf, smaller bundle size, and removes deprecated options.

It's accompanied by majors for all our Redux family packages

## RTK 2.0:

- a new `combineSlices` method for lazy-loading reducers - Updates to `createSlice` to include a `selectors` field and allow defining thunks inside

- Immer 10 w/ faster updates

- Removal of deprecated options

See the migration guide:

- https://redux.js.org/usage/migrations/migrating-rtk-2

All of the Redux libraries now have modernized packaging with full ESM/CJS compat. They also ship modern JS (no transpiling for IE11), which means smaller bundle sizes.

We've also done byte-shaving work to shrink the bundles (extracting error messages, de-duping imports)

## Redux core 5.0:

- The TS conversion we did in 2019!

- Action types _must_ be strings

- `UnknownAction` as the default action type

- Better preloaded state types

- Internal subscription improvements

- Still marks `createStore` as deprecated!

- https://github.com/reduxjs/redux/releases/tag/v5.0.0

## React-Redux 9.0:

- *Now requires React 18 and RTK 2.0 / Redux 5.0*

DEV is a Rails monolith, which uses Preact in the front-end using islands architecture. The reason why I mention all this is that it's not a full-stack JavaScript application, and there is no state management library like Redux or Zustand in use. The data store, for the most part on the front end, is all data attributes.

Oh hey, that's my post!

(yes I spend too much time refreshing HN :) )

FWIW I did end up with a packaging combination that seems to work sufficiently. I never did fix the "FalseCJS" issue that `are-the-types-wrong` is detecting. I played with double-emitting TS typedefs, and the `tsup` tool _does_ actually have support for that now (added by Andrew Branch from the TS team). So it might be more feasible now. But ultimately I decided I was tired of messing with packaging setup and that what I've got is good enough. (hopefully)

We're actually about to launch Redux Toolkit 2.0 and Redux 5.0 this week, assuming the last couple pieces come together. Here's the latest RCs - you can see the current `package.json` files in there:

- https://github.com/reduxjs/redux-toolkit/releases/tag/v2.0.0...

- https://github.com/reduxjs/redux/releases/tag/v5.0.0-rc.1
