There are multiple state management solutions, libraries, approaches, and systems that are getting popular. Of these, the two most popular ones that are often contrasted are MobX vs Redux. These two solutions are popular external libraries that take care of state management for front-end applications.
As for understanding state management, there are three parts to it. One is the State that reveals the application state, the second is the View that renders the current state, and the third is the Action that triggers a state change.
State management offers a structured workflow making the application State insignificant. It is meant to act as a common system especially when application complexity levels are high. The external libraries transfer state from components as independent units for application synchronization.
State management tools like MobX and Redux are necessary when your projects with React need to be scalable and have complexity. These tools help in making the changes obvious and perceptible.
Before we evaluate the difference between Redux and MobX, let us study them individually.
MobX is a battle-tested library that makes state management simple and scalable by transparently applying functional reactive programming.
MobX and React, together, offer a great output in which React renders the app state into renderable components and MobX offers the method to store and update the application state used by React. It assists in the easy management of the local application state.
The fundamental principles of MobX are:
When we observe what is MobX, we see that MobX can execute on any type of ES5 environment that supports Rhino, NodeJS, React Native, and all browsers apart from IE8. It also works well with any type of modernized JS environment. It makes state management easy through Transparent Functional Reactive Programming (TFRP).
MobX offers the writing of minimalistic code that is boilerplate-free and seamless rendering. The code is portable, testable, and decoupled and hence offers convenience to developers. Applications through MobX can automatically store different observable data types in various MobX stores. It makes use of abstraction for hiding the background processes and directly updates its state without prior cloning.
Redux is a predictable state container for JS apps that is predictable, centralized, debug gable and flexible
Redux assists in writing applications with consistent behavior that execute in different environments and are easily testable. With features like live code editing, debugger, and many others, developers have a fantastic experience. As a popular state management solution, it combines functional programming fundamentals with Flux.
The fundamental principles of Redux are:
The singular application state cannot be updated by the application.
Developers must go by clear coding patterns since there is a lot of boilerplate code, which must be made use of. There are 3 major components – the UI to pass the user approach, the Event Handler that receives the action from the UI, and then the Store with Reducers that gets a copy of the State from the Event Handler. The Reducers update the State of the Store.
When we observe what is Redux, we perceive that Redux is mainly used to manage states in which there is a lot of data that keeps changing along with time. It creates user interfaces for front-end technologies like React, Angular, etc., and offers good support for cross-platform development.
In cases of frontend technologies like React, there is their individual application state management. After development, it gets complex to comprehend and that is where the role of Redux comes into good play. It can work with any UI layer, providing a diverse selection of add-on components.

|Founders||Michel Weststrate||Dan Abramov, Andrew Clark|
|Storage Locations||Multiple storage locations||One huge data storage space|
|Application Development||Ideal for small to medium-scale app development||Ideal for complex and large-scale app development|
|Concepts||Depends on reactive programming concepts||Depends on functional programming concepts|
|Learning Curve||Easy to learn and grasp since it follows the OOPS concept||A little tough to learn and grasp since it follows the functional programming|
|Scalability||Less scalable||More scalable|
|Normalization||Denormalized data can be maintained||Only normalized data can be maintained|
|State Management||States can be overwritten and hence can be updated by newer values||States are read-only and hence cannot be overwritten|
|Debugging||Tough to debug as available tools are not that effective||Easy to debug as there are many effective tools available|
|Abstraction||A lot of inbuilt abstraction leading to lesser coding||Lesser abstraction leading to more of coding|
|Maintainability||Less maintainable||More maintainable|
|Purity||Pure functions as they receive a state and return a new one||Impure functions as existing states can be overwritten with new values|
|Boilerplate Code||Implicit in nature and hence packs lesser boilerplate code||Explicit in nature and hence packs a high volume of boilerplate code|
|Community Support and Popularity||Limited documentation and community support, less popular than Redux||Extensive documentation and community support, more popular than MobX|
As we compare the difference between MobX and Redux, we see that there are many parameters that are involved when choosing between the two. Both are used for frontend libraries like React and Angular, making the UI interactive and real-time visualization.
Novices can go in for MobX since it is easy to use and grasp. Those having detailed know-how of programming languages can go in for Redux. If there is a long-term project and there are continuous data changes, you can choose Redux because of its scalability and popularity.
If managing the state of the application is important and if it is a basic application that must be delivered fast, you can choose MobX. Whatever the difference between Redux and MobX, there is a lot both have to offer, and hence choosing either is an advantageous deal!
Finally, it is up to the organization to come up with a selection based on different aspects such as skilled resources, costs involved, project timelines, organizational objectives, etc. The ever-debatable Redux Vs MobX comparison can turn quite interesting yet challenging, for organizations going in for effective state management solutions.
