Redux vs MobX. The Complete Guide

Quick Summary

When it comes to the ever-changing world of front-end development, state management is an essential component in developing robust and scalable apps. Redux and MobX are two examples of notable candidates that have arisen as state management solutions for JavaScript applications. These solutions are beneficial when used with well-known frameworks such as React. When developers are faced with the challenging task of selecting the appropriate technology for their projects, they must fully understand both Redux vs MobX

What is React Redux?

Redux is a widely adopted state management solution amalgamating Flux and functional programming principles. At its core, Redux operates based on the following fundamental tenets:

  1. Utilization of a solitary store, ensuring a singular and authoritative origin for the application’s state.
  2. Adherence to immutability in the state stored within the central repository.
  3. Activation of alterations to the store through actions serving as triggers for state modifications.
  4. State updates are executed by reducers, facilitating the orderly adjustment of the application state.

What is React MobX?

MobX serves as a state management solution designed to facilitate the control of local application state. Its fundamental principles encompass the following aspects:

  1. MobX supports the establishment of multiple stores, each responsible for storing distinct facets of an application’s state.
  2. Anything deduced from the state without additional intervention is recognized as a derivation.
  3. Actions refer to any code segment capable of altering the application state.
  4. All derivations undergo automatic and atomic updates whenever there is a change in the state.

Now, let’s delve into a comparative analysis of Redux and MobX, exploring key features to determine which option aligns better with your specific requirements.

Redux VS MobX: A Comparison

Redux VS MobX: A Comparison

1. Design and Philosophy

In Redux, the developer prioritizes immutability in state updates, and data flow is strictly unidirectional. The application’s state is contained in a single store, and to accomplish the intended state update, pure functions—also referred to as reducers—are urged to be used. The philosophy makes debugging and determining the application’s current state easier because it is based on preserving an open and consistent data flow.

MobX uses reactive programming, which allows for more flexibility in how the state management process is approached. It permits a state to be modified, and the framework will automatically monitor the dependencies among the state’s constituent parts. This flexibility allows developers greater freedom in creating the state of their application, which can be particularly useful when a less prescriptive approach is required because the circumstances demand it.

2. Ease of Use

Redux has a steeper learning curve than other tools of a similar nature despite its capabilities. To achieve this, developers must comprehend ideas like actions, reducers, and middleware. The framework comes with a full suite of debugging tools, including the well-known Redux DevTools, but in return requires additional boilerplate code.

Most people agree that the MobX platform is more straightforward for new gamers. It is more specific since there is less boilerplate and fewer complex concepts. Those who place a high emphasis on ease of use will find it intriguing because it is feasible to proceed with a more intuitive development process in the absence of a predefined framework.

3. State Mutability

Redux places great value on immutability. Updates can be done by creating new copies of the state, ensuring that the history of changes is transparent and traceable. Redux is based on immutability, which is vital for predicting state changes.

MobX, on the other hand, allows for a dynamic state. Any changes you make to observables will instantly trigger updates in all dependent application components, and MobX will automatically and efficiently handle these dependencies. This flexible approach can be applied to simplify some state management sectors.

4. Code Structure

Redux is a framework offering precise and inflexible organization. It is made possible by the distinct roles that reducers, middleware, and actions each play in keeping concerns separate. Using this structured approach contributes to a well-organized and scalable codebase.

Compared to other systems, MobX’s code structure is less rigid and more flexible. This functionality allows developers to arrange their logic and state in the best possible way for their application. While this flexibility may be liberating, it’s also feasible that it will necessitate more discipline to maintain code coherence in larger projects.

5. Scaling Complexity

One primary concern with large-scale apps is their complexity; Redux is an excellent option for these applications. It aids in maintaining clarity and predictability due to its strict structure and emphasis on immutability, which is crucial as the codebase grows.

MobX is more suitable for smaller applications, especially those that prioritize flexibility and ease of use above strict regulations. Because of its permissive nature, quick iterations can be carried out in more straightforward scenarios.

6. Debugging

For Redux, robust debugging tools like the Redux DevTools are available, allowing for time-travel debugging. Developers can effectively track the evolution of the application state to aid in detecting and resolving issues.

MobX greatly simplifies debugging by automatically monitoring changes in observables. Debugging your application may be more effective thanks to the integrated dependency tracking, even though it may lack some more robust features that Redux DevTools provides.

7. Ecosystem and Community

Redux boasts a robust ecosystem well-supported by the community. It has contributed to many extensions and integrations since it is frequently utilized across various frameworks and libraries.

Particularly inside the React ecosystem, MobX offers a supportive and helpful community with an ever-growing environment. While MobX is not as developed as Redux, it is still gaining popularity, and its community is expanding.

8. Performance

Redux’s emphasis on immutability makes performance predictable but can incur additional expenses when new state copies are created. The trade-off is usually reasonable, given the benefits of having an open and verifiable state history.

MobX now operates with increased efficiency and uses automatic dependency tracking to minimize the amount of unnecessary updates. Because MobX is reactive, it contributes to efficient state management and is appropriate for applications prioritising performance.

9. Learning Curve

Redux has a steeper learning curve, especially for people unfamiliar with basic ideas like actions, reducers, and middleware. A thorough grasp of these concepts is necessary to utilize the framework effectively.

MobX has been designed to have fewer complex ideas to be more approachable. As a result, this makes it easier for beginners to understand and quickly integrate into their projects.

10. Use Cases

Redux is an excellent option for large teams, projects requiring significant scalability, and applications with complex state management requirements. Its regimented nature is beneficial in maintaining a disciplined attitude toward development.

MobX is an excellent option for smaller projects, smaller teams, and situations where rules are less crucial than flexibility in state management. Because of its permissive framework and ease of use, it is best suited for quick iterations in simple circumstances.

Redux vs MobX Scalability

Redux is more straightforward to scale than MobX since it is more opinionated and assumes that pure reducer operations will be performed. Because Redux is pure and opinionated simultaneously, it can scale.

Pure functions are more accessible to test because they are predictable and uncomplicated, which eventually leads to code that is easier to maintain and more scalable. This is perhaps one of the most significant benefits of utilizing Redux over MobX.

Redux vs MobX Development Philosophy

Redux is a framework that follows the rules of unidirectional data flow, centralized storage, and immutability. Its structured methodology, which emphasizes using actions, reducers, and middleware to provide controlled state management, was inspired by functional programming.

Reactive programming is the foundation of MobX, allowing for a more flexible approach to state management. MobX encourages simplicity and flexibility, making it a desirable choice for developers seeking a less restrictive development ethos. It supports MobX’s features, namely automatic dependency tracking and changeable state.

Redux vs MobX: Migration and Integration to React

You must carefully plan the transition process to change your application’s structure and state management paradigm to move from Redux to MobX successfully. The following are crucial steps and considerations while switching from Redux to MobX:

  • You must familiarize yourself with the fundamental differences between Redux and MobX. Understanding the observable state, the lack of reducers and actions, and the MobX reactive programming style are all crucial.
  • You should identify your Redux application’s parts, actions, and reducers. Determining which codebase components will be affected by the migration is vital.
  • Rather than performing a full-scale migration, consider introducing MobX piecemeal. First, you should integrate MobX into specific parts or features for a smoother transition.

Conclusion

Regarding developer community engagement, popularity, and scalability, Redux outperforms MobX. However, if your goal is to rapidly acquire proficiency and construct uncomplicated applications with minimal boilerplate code, MobX could be the more favorable choice.

FAQ’S

Yes, developers often use Redux with React to build different types of applications but both are independent from each other so you can even use them separately.

You should think about using MobX in React because it makes sure that all the changes to the application state are saved automatically and it makes the app bug-free.
