List of 8 super useful React State Management Libraries - Learn which one you should use
What is React State Management?
React components have built-in objects called states. A React state is similar to a JavaScript data structure. Components use the state to store reusable assets. It is possible for the state of a component to change frequently, which requires the component to be re-rendered whenever the state changes.
When it comes to managing React states, it is not as straightforward as using simple React hooks like useState or useReducer.
There are a large number of states, and there are also a large number of state management libraries available, and this number is expanding every day. Therefore, the best approach is to select the one that best meets your needs and get to know them all in case anything better emerges.
List of some most popular RSM libraries
1. Redux
Before choosing any library, you should know what kind of problem you are having. Don’t use it just because someone told you about it. Before using it, do your homework. Not all apps need Redux. You should use Redux when managing states locally becomes messy. Using Redux requires you to learn more concepts and write more code.
See the illustration below to understand how Redux works:
Some of the advantages of Redux are its community support, server-side rendering, easy debugging, and state persistence. You can use Redux with React or any other library. Including dependencies, it weighs only 2 KB.
Dan Abramov, one of the redux developers, states:
I would like to amend this: don’t use Redux until you have problems with vanilla React.

2. Redux Toolkit
When developing redux apps, the Redux Toolkit is recommended. It makes your code much better. Redux Toolkit incorporates our suggested best practices, simplifies most Redux tasks, prevents common mistakes, and makes it easier to write Redux applications.
Install:
# NPM
npm install @reduxjs/toolkit
# Yarn
yarn add @reduxjs/toolkit

3. Rematch
Rematch is Redux's best practice. Switch statements, thunks, action types, and action creators have been removed.
As a replacement for Redux, Rematch has many great features.
Rematch eliminates boilerplate, is lightweight (less than 2 KB), needs no configuration, and supports TypeScript and React devtools.
Additionally, it supports React Native, enforces best practices, has hot reloading, adds reducers dynamically, allows you to set up multiple stores, is expandable with plugins, and is simple to use.

4. Recoil
Recoil is an open-source React state management library developed by Facebook. It’s more similar to React. Throughout the application, states are passed through atoms and selectors. This reduces unnecessary re-rendering and increases performance. Recoil is an advanced approach to React state management.
See the illustration below to understand how Recoil works:

5. Hookstate
Small most concise, fast state management library that is based on React hook.
Features:
Flexible API
Easy to learn
Incredibly Fast
Better performance
Supports TypeScript
Extensible with Plugins

6. Jotai
Jotai is a minimalist yet flexible library to manage a simple React global state.
In comparison to Recoil, Jotai has many features. From what I have learned about Recoil and Jotai, if you choose one library from these two, choose Jotai. Recoil has issues with memory leaks. Recoil’s performance is superior to Jotai’s, has less boilerplate and a smaller core API, etc.
Some of the main features of Jotai:
TypeScript focused
No extra re-render
No actions
No stores
No reducers
No dispatchers

7. Zustand
There is probably no doubt that Redux is the most popular library for managing global states. Nevertheless, libraries like Zustand manage global states more pragmatically and straightforwardly.
Features:
Scalable and fast
It does not require a boilerplate
Compared to Redux, it is less complicated
A smaller number of lines of code
Developers have responded positively

8. MobX
It is a simple and straightforward state management library that applies reactive functional programming. The library is lightweight, has minimal code to write, and has no boilerplate. It provides architectural freedom and effortless, optimal rendering.
See the illustration below to better understand the concept of MobX.
