Difference Between Mobx and Redux
Mobx is a testing library used to make scalable and simple state management with the help of TFRP (transparently applying functional reactive programming). It will help to make the state consistent. It follows the concept that everything that can be derived from the application state will be derived automatically. Redux is a javascript library for maintaining the application state management. Redux helps to develop applications that behave consistently in all environments. It also helps developers to develop, test and debug the code easily.
Mobx
- Michel Weststrate developed mobx. It was initially released in the year 2015. It is mainly written in JavaScript. In a state, like arrays, references, objects are considered the application’s data cells. Derivations are considered as the value that can be processed automatically by the application state like formulas and charts in an application.
- Reactions mainly take care of input-output operations and updating DOM, and network requests need to be handled on time automatically. Actions modify the state, and Mobx makes sure that all the changes need to be processed synchronously.
- Mobx can run on any ES5 environment. It supports node.js, rhino and all the browsers except IE8. It supports react native also. Mobx generally consists of state, derivations, reactions, and actions.
- The one thing that needs to take care of is that Mobx is not a framework as it does not know how to structure your code, how to process and store the data. Mobx can be applied to any modern JS environment.
Redux
- Dan Abramov and Andrew Clark developed redux. It was initially released in the year 2015. It is written in JavaScript. It is mainly used with libraries to build user interfaces for front-end technologies like React, angular, etc. It does support cross-platform.
- Redux is also referred to as an intuitive state container. It can be used with React and another library view as well. Redux is very simple if you know flux or you have developed something on flux.
- Redux is mainly used where a reasonable amount of data gets changed over time. If the data is not changing frequently, then Redux usage is less. It is used as a pattern for managing the application state.
- Some libraries or front-end technologies like React have their own application state management, so while using these libraries, one should learn its inbuilt capabilities. Sometimes after developing the application, it becomes complex to understand and code; it is hard to know how the state has been changed. In this scenario, Redux is helpful and used.

Below is the top 8 difference between Mobx vs Redux
Key differences between Mobx and Redux
Both are popular choices in the market; let us discuss some of the major difference:
- In Mobx, the de-normalized data can be kept. In Redux, mainly, the kept data is normalized data only.
- Mobx mainly uses an observable to store the data. Redux mainly used javascript objects to store the data.
- In Mobx, the updates can be done automatically with the help of an observable attribute. In Redux, the updates need to monitor manually.
- In Mobx, the states can be overwritten, which also referred to as an impure state because the state can be updated simply with the new values. In Redux, the state is referred to as a pure state as states are read-only and cannot be overwritten simply. It means it uses an immutable state.
- In Mobx, debugging is difficult to do as tools available for Mobx is not up to the mark and which results in unpredictable responses many times. For Redux, there are many developer tools available; pure functions and less abstraction make debugging easier. The response is also predictable with the use of the flux paradigm.
- Mobx is easier to learn and has a simple learning curve. If one knows the OOPs concept, it is easy to learn Mobx for javascript developers. Redux is difficult to learn, as it has a steep learning curve. It follows the functional programming paradigm, which requires a lot of effort to grasp things.
- In Mobx, a lot of built-in abstraction is there, which leads to less code. In Redux, there is less abstraction and a need to write more code.
- Mobx is mainly used to develop the application fast and in less time. Redux developed applications generally take time because of their complexity.
- Mobx is less maintainable. Redux is more maintainable.
- Mobx has less online community and developer support as compared to Redux. Redux has way ahead of developer and online community support than Mobx.
Mobx vs Redux Comparison Table
The primary Comparison is discussed below:
| The basis of comparison |
Mobx |
Redux |
| Definition | It is a testing library to make simple state management with the help of TFRP. | It is the Javascript library for managing the application state. |
| Programmed | It is mainly written in JavaScript | It is originally written in ES6 |
| Developed | Michel Weststrate develops it | Dan Abramov and Andrew Clark develop it. |
| Datastore | In Mobx, there is more than one store for data storage. | In Redux, there is only one large store for data storage. |
| Application | Mobx is mainly used for small and simple applications | Redux is mainly used for complex and large applications. |
| Scalable | Mobx is less scalable comparatively. | Redux is mainly used for scalable applications |
| Performance | Mobx gives good performance | Redux is not much efficient. |

Conclusion
Both are the libraries that are used to manage the application state in one way or the other. Both are mainly combined with front-end libraries like react and angular to develop the user interfaces more interactive and show changing the data over time.
Mobx is mainly preferred to use for beginners as it is simple and easy to learn. Redux can be preferred for those who have a strong understanding of functional programming skills. It has been seen that Redux is well established and popular among the developers, whereas Mobx is not that popular, but Mobx can be a good alternative for managing the state of the application.
Both are great libraries to work on, and these can be selected depending on the requirements and availability of resources. Happy learning!!
