20 Best Libraries and Tools for React Developers

Reselect is a library for creating memoized “selector” functions. Commonly used with Redux, to slice state and provide just the necessary subtree to a React component.

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.😉👍 welcome to the community. 😁

TypeScript is terrible for library developers
16 projects | news.ycombinator.com | 23 Aug 2022
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" , 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 .
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 . 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 . 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 :)
Extreme Explorations of TypeScript's Type System

We do a _lot_ of this in the Redux library repos (examples:    ). We have some incredibly complicated types in our libraries, and we have a bunch of type tests to confirm expected behavior.
Generally, these can just be some TS files that get compiled with `tsc`, but it helps to have a bunch of type-level assertions about expected types.
I actually recently gave a talk on "Lessons Learned Maintaining TS Libraries" , and had a couple slides covering the value of type tests and some techniques.

What's new in Redux?
3 projects | /r/reactjs | 30 Dec 2021
While Reselect has always been a separate library from Redux itself, it's in our Github org. The previous maintainer had to stop working on it, so a couple months ago we did some major updates to Reselect. Reselect 4.1.x has huge improvements to its TS types for better inference, and adds a new set of customization options like cache sizes > 1.

You should think about using some client state management libraries like Redux. Redux gives you the possibility to encapsulate states and manipulate it through functions. https://react-redux.js.org/

`useSyncExternalStore` was shipped live in React 18.0 and is fully ready for production use.
Source: I'm the primary Redux maintainer, and worked with Andrew Clark of the React team to nail down the semantics and behavior needed by `useSyncExternalStore` in practice. They had the idea, but discussed a lot of the necessary use cases with us and other lib maintainers, and a lot of its internal implementation is directly related to how React-Redux's `useSelector` hook was implemented already.
I built the first working code that used it by prototyping React-Redux v8's switch from our own internal subscription handling to `useSyncExternalStore` instead and gave Andrew feedback:

State Management with Redux
5 projects | dev.to | 22 Dec 2022
Redux is a popular state management tool that can be used in conjunction with React to manage the state of an application. It works by implementing a unidirectional data flow, in which actions are dispatched to a central store, which then updates the state of the application and sends the updated state back to the components that need it.

Redux vs Context, what exactly does Redux accomplish that context fails to do?

if you have a more complex component hierarchy, and the component who receives the DB response is not on the top, you might consider introducing a State management tool, such as Redux: https://redux.js.org / https://react-redux.js.org
useSyncExternalStore() needs an update
2 projects | /r/reactjs | 16 Sep 2022
FWIW I was actually the primary alpha tester for useSyncExternalStore - I prototyped using uSES in React-Redux v8, and worked with Andrew Clark to nail down what the final API and behavior should be.
I am sick and tired of react-redux. Who has some good alternatives?

Additionally, the idea that the props.todoAdded() version from connect automatically dispatched when called was always a source of confusion and led to lots of questions. So, Dan Abramov specifically suggested that we drop the idea of auto-binding as we were designing the hooks API to make it more clear what's actually happening, and we did.
