Copilot: Weapon For Laid Back Developers
In my example I am using Redux Toolkit and I got a prompt for actions to login and logout the user. If I need more functions, I can simply start typing the name, and Copilot provides the completion. For instance, in the example, I'm adding a function to update the user. And of course at the end of the file it suggests the exports.

Redux Toolkit 2.0

This Month in React Nov 2023 β Redux Toolkit 2.0, Kent v Lee, Prettier bounty
Redux Toolkit 2.0 is almost here! Hopefully shipping by this weekend :) Migration page
- Redux Toolkit 2.0: new features, faster perf, smaller bundle sizes (plus major versions for all Redux family packages!)

Redux Toolkit 2.0: new features, faster perf, smaller bundle sizes, and more
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*

Blogged Answers: My Experience Modernizing Packages to ESM
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:

Setting up Redux Persist with Redux Toolkit in React JS
However, Redux, or pure Redux to be specific, can be quite verbose and boilerplate-heavy. It requires a significantly lengthy setup, which is where Redux Toolkit comes in handy, offering a simplified and more efficient way to set up and manage state in your React applications.
-
How to manage state in a React app using Redux.
In this tutorial, you managed the state of a React Todo app using Redux. Next, learn how to manage the state using the Redux Toolkit. Redux Toolkit makes it easier to write good Redux applications and speeds up development. Furthermore, learn Redux DevTools to help you trace when, where, why, and how your application's state changed.

Redux Toolkit 2.0: new features, faster perf, smaller bundle sizes, and more
- Throws better errors in an RSC environment
- https://github.com/reduxjs/react-redux/releases/tag/v9.0.0
## Reselect 5.0:
- Switches to a new `weakMapMemoize` memoizer as default
- Renames `defaultMemoize` to `lruMemoize`
- Allows passing memoizer options direct to `createSelector`
- Many TS improvements
- https://github.com/reduxjs/reselect/releases/tag/v5.0.1
## Redux Thunk 3.0:
- Drops the default export and switches to named exports ( `{thunk, withExtraArgument}` )
- https://github.com/reduxjs/redux-thunk/releases/tag/v3.1.0
This has been a _huge_ year-long development effort!
We're thrilled to get these improvements out. The tooling and bundle improvements will help all users, and we think the features and TS changes will improve the Redux dev experience significantly.
Thank you SO MUCH to everyone who has contributed or helped test out the work!
Please file bug reports for the inevitable issues that pop up post-release!
but now I'm going off on a conf trip and going to take a very well-earned break from Redux work for December :)

For the redux part, you need to use two hooks. The first one is for sending data and that is useDispatch and for getting data from redux is useSelector. This link will help you a lot. The only that left is Reselect concept. The thing with redux is that when you update one state inside of the redux store the whole thing updates itself so basically it may cause you to re-render your components. Reselect will prevent that but it's a little bit advanced topic whenever you were comfortable enough with redux I suggest you learn to use reselect. Other than these Really good work with the project.ππ welcome to the community. π

Killing mutants to improve your tests
At my current client we're working on having a frontend architecture for writing SPAs in JavaScript similar to re-frame's one: an event-driven bus with effects and coeffects for state management[1] (commands) and subscriptions using reselect's selectors (queries).

TypeScript is terrible for library developers
Heh, it's amusing to see Redux Toolkit referenced here. I'm one of the two main RTK maintainers. My co-maintainer Lenz Weber is responsible for most of our TS type wizardry.
Agreed that writing TS types for libs can be a pain. I actually did a talk recently on "Lessons Learned Maintaining TS Libraries" [0], where I talked about some of the techniques we used, and some possible TS changes that would be helpful for us as maintainers.
As one recent example, TS made a change in a 4.8 pre-alpha that broke RTK's `createSlice` types. Lenz tried to come up with a fix, couldn't, and had to add a workaround to check what TS version is being used and specifically use an altered type. Since there _isn't_ a good way to know what TS version is being used, Lenz resorted to hacking together a new package that abuses the `typesVersions` property to define a different TS type for _every_ TS major+minor version combo, and then used that to decide what the RTK type should look like conditionally [1].
Another pain point is debugging type transformations. I reworked the Reselect types in 4.1.x to do a much better job of inferring the argument types for the final selector, based on the intersection of all the input selector arguments. This ended up as a monstrous type that does a types-level map + transpose + intersection [2]. It took me weeks to get this working right, and I frequently had to break it down into multiple small intermediate types to see how TS was processing each step.
I know that someone on Twitter was recently working on an alternate TS type-checker based on bytecode, and they said they had some kind of a working types-level debugger [3]. Having something like that officially, where I could see each step of how TS was transforming the types, would be _hugely_ valuable.
There's a couple folks like AndaristRake who are able to dig into the internals of the TS compiler itself to trace how it's interpreting the types. I definitely don't have that ability :)
