Redux vs MobX vs Flux

State management in hefty applications is a daunting task. Redux, MobX, and Flux are popular technologies permitting you to manage the state of your application. These tools are great as they allow the developers to swiftly solve state management issues. Here, we have tried to compare these three amazing technologies.

A detailed Comparison bet Redux vs MobX vs Flux


It is a famous state management solution combining both functional programming concepts and Flux as well. Its basic principles are:

  1. It has a single store which is the only source of truth
  2. Immutable state in the store.
  3. Actions request alterations to the store.


Mobx solves the same issue that Redux shows i.e state management. It becomes easy to manage the local state within your application with Mobx. Your application is treated like a spreadsheet by it.Learn about the differences between >Redux vs MobX.


Flux is a designed pattern, or an application architecture made and used by Facebook for creating a user interface or client-side web app. It follows a unidirectional flow of data supporting or empowering a composable look of React's components.



Local data is kept in the store and the store has the whole application's state. It captures all the states in a hefty JSON object.

1. Redux
You will find just one store in Redux and its immutable state makes it simpler for you to know where you will get the state/data. There is a single JSON project representing the store and you can divide the code into various reducers. You can separate the concerns logically with these reducers. This is an intuitive approach for various developers as they refer to the single store for the state of the app. You will find no possibility of duplication or confusion similar to the data's current state.

2. MobX
MobX has multiple stores and these can be easily separated logically. So, the state of the application could be in any tore. Many applications are made to have at least two stores. One is for the domain state and the other is for the UI state. You will find one benefit that the domain is reusable in other apps also.

3. Flux
Flux with patterned designs has multiple stores. It uses stores to cache any app which is associated with state or data. There is an issue with updates with multiple stores in Flux. Data can be read in Flux and the views in flux architecture will be reminded of changes within stores through the observer pattern.

Data Structure

1. Redux
It uses JavaScript objects that are plain as data structures to store the state. You have to track the updates manually in Redux.

2. MobX
It uses observable data and helps in automatically tracking modifications via implicit subscriptions. You can easily track the updates as they are tracked automatically. So, it makes the developer's work easier.

3. Flux
All data flows unidirectionally through the dispatcher as a central hub.


1. Redux
It has no dispatcher entity and its store has already baked in the dispatching process. The store shows a few easy API functions and one of them dispatches actions.

2. Flux
It has a single dispatcher with all actions passing through the dispatcher only. Flux cannot have several dispatchers and it's a singleton object. We know that Flux can have multiple stores and the dependencies between the stores require a single manager i.e dispatcher.

3. MobX
It does not have any dispatchers.


1. Redux
Redux is a single store which makes the job debugging easy. It does not have a dispatcher, so how would it handle debugging? Data management is simple in Redux and debugs as the whole application's state is operated within a single store. Besides, all the components' state completely depends on one object tree. So, it could be done to log all the actions performed to find a certain point. Furthermore, redux offers the best Live Code-Editing option also with a time-traveling debugging characteristic. It enables you to replay and rewind your debugging action.

2. Flux
Flux ensures easy debugging with the help of a dispatcher. It is helpful for actions comprising side effects such as updating views, making the clear code, and debug by developers. It has a singleton dispatcher and all of its actions pass via the dispatcher. Moreover, it defends tough to debug cascading updates.

3. MobX
With more abstraction, it is tough to debug in MobX. Also, its developer tools are average. So, one can get unpredictable outcomes many times.


So who is the best? It seems tough to find one way or the other. However, you can compare these technologies yourself and make a wise decision. MobX is suitable for simple and tiny applications as it is easy to learn. Redux is recommended for a huge scalable application with big coders' team. Flux shows the issues of handling applications state on the client's side. Overall, these technologies make your applications great to work and attractive as well. You can consider the above-mentioned comparisons that suit your need the best.
