React State Management Libraries

dots

React apps are developed with components, and they have the resilience to manage the state internally, making them ideal for applications with fewer components or smaller applications.

State Management is one of the crucial components of any application. An application state represents what users see and interacts with and what data is stored in the application.

React apps are developed with components, and they have the resilience to manage the state internally, making them ideal for applications with fewer components or smaller applications.

State management libraries enter the picture as application size increases and maintaining shared states across components becomes challenging.

Although React offers built-in tools for state management, corporations choose third-party state management libraries over built-in ones due to certain limitations.

Third Party React State Management Libraries:

Redux

Redux

Redux is one of the most well-known state management libraries. Redux API is a must-have when it comes to state management libraries. Although Redux is used with React, its core is standalone; therefore it can be implemented with any UI library or framework.

Redux API allows react components to interact directly with the redux store, allowing developers to avoid custom coding of the states.

Redux is essentially the first state management library and it was introduced on 2nd June 2015. Redux is a JavaScript state container that holds the application's state. An application state encompasses all components and UI logic.    

How Redux works

Redux provides global store called redux store where application data resides. To update the store, developer dispatches an action that goes to the reducer. The reducer modifies the state in immutable manner corresponding to action type. Because of the redux store, application state behaviour can be predicted; hence, redux is referred to be predictable. 

When to use redux

Redux is recommended when an application has many components and administration becomes troublesome. Moreover when the app has medium or large-sized codebases, and might be worked on by many people. Redux maintains application data in immutable state tree which cannot be altered directly. 

Because redux has been on the market for a while, it has several drawbacks, such as boilerplate code; to address this issue, the Redux-toolkit was created. Redux-toolkit avoids excessive code redundancy.

Companies that currently uses Redux library

  • Instagram
  • Amazon
  • Robinhood
  • Stack
  • Hepsiburada
  • Tech Stack
  • DoorDash
  • Revolut

Perks of Redux

  • Application states are easy to manage and in predictable way.
  • Enables time travel to review previous modifications
  • State data stored in a single object tree
  • Community support
  • Enhanced Performance
  • Simple debugging 
  • Redux-toolkit library solves the problem of boilerplate code
  • Excellent for unit testing since Redux is purely functional.

Cons of Redux

  • Takes some time to comprehend if the developer is unfamiliar with functional programming.
  • Relies on immutability, making reducer implementation challenging.

MobX

mobx

MobX is another famous state management library. MobX follows the opposite approach to traditional Redux API. MobX is built around the observer or observable pattern.


MobX is an independent and scalable library that mostly collaborated with react applications. 


MobX follows the TFRP approach that elaborates transparent functional reactive programming which means it notifies subscribers about the modification in states, developers don’t need to individually to object, developers can use just the MobX state method and it will automatically subscribe to object and notify about new updates.

How MobX works

Has global store as redux with other properties like observal class and action, state, and observals. Have to call makeobserval() method inside the constructor of Javascript class then other properties of mobx can be implemented. The feature that differentiates it from Redux is mutability.

Why use MobX:

MobX implements Transparent Functional Reactive Programming to ensure that all changes in the application state generated by specific actions are automatically processed by all computed values and reactions.


MobX is synchronous and free of glitches.


MobX is free from boilerplate code.

Companies that currently uses MobX library

  • Udemy
  • Canva
  • Frontend Stack
  • Tumblbug-com
  • Ataccama ONE
  • Swat.io
  • Hahnode

Perks of MobX

  • Computed properties
  • Easy to learn
  • Flexible architecture 
  • Has own router package (MobX-router)
  • Straightforward 
  • Streamline Optimal

Cons of MobX

  • Nested format makes harder to track the data
  • Slower in speed
  • Difficult to debug
  • Duplicate code 
  • Too much architecture freedom

Recoil 

recoil

Recoil is an experimental state management library invented by Dave McCabe, a Software Engineer at Facebook. Even though recoil is used by many applications or companies, the recoil community is really small and can't be thoroughly recommended for an enterprise project.


Recoil is a one-of-a-kind and experimental concept for future aspects.


Recoil library uniquely approaches state management. The Recoil library is based on two concepts: Atoms and Selector.

How recoil works:

Recoil works with two terms Atoms and Selector.


Atom: Atom contains the unit state of an application. These unit states are updatable.


Selector: Selector is represented as the derived state. Selectors are also called pure functions which derive new value from the present state.


Recoil has a global state same as the Redux library. However, it addresses the shortcomings of Redux and context API. Developers must subscribe to components to get notified if there are changes in the state values. Recoil keeps track of atoms and the selector's state to determine when to notify about subscribed component and re-render. Selector's values tend to be frozen to avoid bypass problems when modification. The recoil model aids the bug detection issues.


Atoms and selectors are the same from the consumer's perspective; all they have to do is subscribe to some reactive element of the application and implement it.

Why use recoil:

Recoil is easy to install and lightweight state management library. Recoil is endorsed by Facebook and is already in use by several applications, implying that a stable version will be released at some point. Recoil ensures easy modification and smooth delivery of any business application.


Companies that use Recoil js as their tech stack

  • RippleAI
  • My Franchise
  • PlatypusApp
  • Refi App
  • STRAK CMS
  • Panic Lobster
  • Gradient Art
  • teamRobot
  • Treedis

Perks of Recoil

  • Very easy to learn, simple API.
  • Minimal boilerplate and reactish approach
  • Performant granular updates.
  • Dynamically created state
  • Async Support.
  • No impact on code-splitting
  • Concurrent mode support
  • Minimalist and Reactionary
  • Data Flow Graph
  • Observation across apps
  • Light weight 
  • Handles large volume of data easily

Cons of Recoil

Recoil is young and fresh but has neither community nor ecosystem at the moment. Even though recoil is maintained and tested by Facebook, a large React application cannot rely completely on a library with weak community support.  Furthermore, it is experimental, making it extremely riskier for enterprise projects.

Rematch

rematch

The rematch has been in existence for almost four and a half years now and is rapidly growing in popularity. The rematch is a recommendable redux alternative; however, being built on Redux it is a bit larger than the redux library.


The rematch is a framework-independent library that works great with react yet also has the potential to work effortlessly with other frameworks such as Vue, Angular etc. Rematch offers important features such as typescript steroids with autocomplete capabilities and the ability to avoid regression simultaneously Rematch leverages the same concept of Redux but offers more efficiency while alleviating its shortcomings.

How Rematch works

Rematch architecture contains properties such as Models, Loading Plugins, Persist Plugins, and Redux. 


Models: Models are foundation of store. Models consist of states, reducers and effects in one container instead of separate like Redux.


Plugins: There are two types of plugins in Rematch architecture.  Loading Plugins and Persist Plugins.


Loading Plugins: Loading plugin adds automated loading indicator effects to avoid maintaining state manually. 


Persist Plugins: Persist Plugins includes all basic configurations such as blacklist, whitelist, version, storage and transforms.


Redux: Redux contains middleware to perform certain actions between store and frontend.


Rematch is also considered the upgraded version of the Redux toolkit.

Perks of Rematch

  • Reduced Boilerplates
  • Written in TypeScript
  • Auto-completion of code 
  • Easy to extend custom plug-in APIs
  • Async/await effects

Closure

These were some of the famous and most used react state management libraries.  The list of libraries doesn’t stop here, and almost every day, new libraries and state management technologies approach the market.


Now the controversy is how to choose the best state management library for business projects. The answer is what works according to your business requirements.
