Are you architecting your next application and uncertain about which state manager to use? Have you heard of Redux and MobX, and are you curious about how they differentiate in managing state? Or are you wondering which one among the two may best suit your project’s requirements?
Several developers have a tough time trying to decide between Redux and MobX for state management for their applications. This difficulty stems from various factors such as lack of clarity, performance, and implementation differences, as outlined by industry experts, Dan Abramov and Mark Erikson. There is an evident need to address these concerns and potentially pave a way for developers to have a clearer understanding while making their decision.
In this article, you will learn about the fundamentals of Redux and MobX, exploring their key differences. The similarities these libraries share will also be analyzed. We aim to delve into vital aspects such as performance, scalability, community support, ease of integration, and the learning curve. Recognizing these factors can significantly aid developers in choosing the most beneficial management tool for their project.
We will also provide real-world application examples utilizing both Redux and MobX. The purpose of this is to showcase each tool’s strengths and identify any potential drawbacks. Finally, we will offer a conclusion drawn from the examinations, allowing you to make an informed decision.
Definitions: Understanding Redux and MobX
MobX, on the other hand, works slightly differently. It is a state management solution that you can think of as spreadsheet-like. Instead of keeping a strict log of events like Redux, MobX reacts to the current state of your application, automatically updating only the components that depend on that piece of state. MobX is more like the automatic formula calculations in a spreadsheet.

Comparing Redux with MobX
On the other hand, MobX presents a more liberal approach to state management. It utilizes an observable state paradigm where any part of the state can be observed and react to changes. Things change in place and the system ‘reacts’ to those changes. MobX is especially great when working with complex states due to its simplicity and less boilerplate code.
Core Concepts of Using Redux for State Management
Understanding the core concepts of Redux is vital in unlocking its full potential for state management. Simplified, the Redux model operates around three central concepts.
- Actions: These are payloads of information sent from the application to the Redux store to be used in state updates.
- Reducers: Function that accepts the current state and an action, and returns a new state.
- Store: This is where the application state is housed.
Actions are dispatched by calling the store’s dispatch function. Typically, action creators – functions that create actions – are used, instead of dispatching actions directly. Once an action is dispatched, the store’s reducing function is called with the current getState() result and the dispatched action to calculate the new state. The state returned by reducers is then saved in the store as the new state.
Redux encourages separating the state tree into many smaller reducers to handle a particular slice of state. This separation makes the reducers more understandable and easier to test. Besides, you can also apply middleware to the store to handle processing of data as it flows through your application.

Identifying Pain Points: Tackling Redux’s Issues
Redux’s main problem lies in its steep learning curve and its verbose nature – developers often complain about having to write a lot of ‘redundant’ code. It requires understanding of numerous concepts like actions, reducers, store, middleware etc. before a developer can be productive with it. Furthermore, implementing common tasks such as caching server responses, manipulating large objects or arrays in the state, can be complicated. This inherent complexity makes it difficult for a developer to implement it effectively in smaller projects or something that requires quick prototyping.
Championing Alternative Approaches: Dissecting MobX
Turning to MobX, it provides an uncomplicated and more agile alternative. For instance, where Redux requires three different pieces (actions, current state, reducers) to update the state, MobX gets it done within objects and classes making it more familiar and straight-forward. This approach simplifies state management and speeds up the development process making it ideal for smaller projects or prototypes. Plus, MobX’s ability to update state directly and automatically deriving the minimum number of updates to the UI is a highpowered advantage making app’s performance highly efficient. For instance, a large scale project like Mendix, accelerated its development several folds by replacing Redux with MobX, shielded codebase from side-effects with easy testing, and taming the management of large-scale state.
The Epic Face-Off: Comparing Performance, Simplicity, and Versatility in Redux and MobX State Management
The Challenge in Keeping It Simple and Efficient
How often have you faced the dilemma of picking the right state management tool for your next big project? The odds are, probably pretty frequently. When it comes down to choosing between Redux and MobX, the decision can be even more bewildering. These two are undoubtedly the front runners in the state management space, each with their unique selling propositions and strengths.
Redux vows by the predictability of state transitions, implementing a strict and linear data flow. On the other hand, MobX delivers a more flexible and intuitive model, enabling direct state modifications. You can utilize both to write performant and maintainable code, but respective paradigms come with their own trade-offs.
Working Through the Challenge
The primary conundrum occurs when the developers need to decide which one out of Redux and MobX would serve their specific project requirements more effectively. Redux is often criticized for its boilerplate code, leading to potential productivity loss. On the contrary, the operational simplicity of MobX can be misleading, and managing derived data can get complex.
Despite these challenges, both Redux and MobX can perform exceptionally well if understood and used to their fullest potential. Redux shines when it comes to large-scale applications that require strict data handling and debugging capabilities with its action-based data flow. Simultaneously, MobX’s ‘reactive’ approach works wonders for relatively smaller projects that can benefit from minimized boilerplate and greater simplicity.
Following Good Practices
How about examples where these tools have been used maximally? Take Twitter Lite, for instance, which is built with Redux. The team at Twitter took advantage of Redux’s predictable state transitions and middleware support to manage a complex global state. This helped them build a high-performing and light-weight web app that felt responsive and smooth, despite being fetched directly from a network-first service worker cache.
On the other hand, MobX has been used successfully in smaller-scale projects where simplicity and less boilerplate are the need of the hour. One such example is Mendix Studio Pro. The app’s developers leveraged MobX’s simplicity to manage the local state of their app without having to write tons of boilerplate code. By integrating MobX into their React application, they could constrict operational complexity and could focus more on building a better user interface.

Redux introduces a single store where your entire app’s state lives, which makes debugging easier, while MobX provides multiple stores. The state changes in Redux are explicit and traceable, but in MobX, they are more automatic and less predictable.
One might choose MobX over Redux because of its simplicity as MobX has less boilerplate, and it’s faster to set up. Also, MobX’s automatic state management can be more intuitive and simpler for small to medium-sized applications.
While you can use both Redux and MobX in one application, it’s generally not recommended as it can lead to unnecessary complexity. Ideally, you should pick the one that suits your application’s requirements and team’s expertise best.
