React Native App Success: Should You Use Redux, MobX, or Recoil?

Building a React Native application that seamlessly handles complicated data and builds interactive user interfaces requires a state management library.

State management libraries in React Native refer to solutions that help development teams to handle dynamic and complex data within React Native applications efficiently. Redux, MobX, and Recoil are some of the top picks when teams need to build an app that performs smoothly.

For determining the app’s responsiveness and writing maintainable code, choosing state management in React Native is an essential aspect. But what are these state management libraries? And how do they differ from each other? This blog will help you understand the top React Native state management libraries & their pros and cons so that you have a clear mindset to determine which tool is better for you.

Understanding State Management in React Native

In React Native, there are mainly two types of data that control a component- props and state. Out of these, the state is a kind of component-specific memory that lets you store data and change it by calling the setState function. Whenever there are multiple components to interact with and change the same data, it gets difficult to handle the state.

That’s where state management libraries become essential, as these provide a structured way to store and update state across numerous components. Leveraging React Native app development services and state management libraries allows you to smoothly inspect the app’s state and actions, thus ensuring the app’s consistency.

Popular React Native State Management Libraries

Now that you have understood the state management in React Native, let’s explore the top 3 production-ready state management libraries and their unique pros and cons:

Redux

Redux is an open-source JavaScript library for predictable state management. It provides development teams with a strict unidirectional data flow that stores all app state in a centralized container.

Pros of Redux:

• It enhances debugging by performing time-travel debugging with the help of Redux DevTools. This allows you to step backward through the state of your application at different points in history.
• It ensures that all the state updates are traceable, helping developers to understand the logic of why, what, and when the state is changing for a particular data.
• With its vast community of experienced developers and testers, it provides extensive resources, a reusable ecosystem, and learning tutorials that are free to use.

Cons of Redux:

• It is not suitable for smaller projects that require limited state management components.
• The Redux architecture and concepts like time travel debugging, actions, and reducers can be challenging to understand for beginners.

MobX

MobX is a signal-based state management library that makes the application state more flexible using observables. This means that it makes the state “observable” and automatically updates the component “observe” whenever a change occurs.

Pros of MobX:

• With MobX’s reactive nature, the UI widgets can be maintained and automatically synchronized whenever the data is changed.
• It has minimal setup requirements and less boilerplate code, and also eliminates the need for manually managing the application state.
• It has a scalable architecture that can handle the state effectively for both small and large applications.

Cons of MobX:

• It has fewer middleware and development tools available when compared to other state management libraries like Redux.
• It has an automatic update feature, which sometimes makes it hard to trace how and when the state was changed.

Recoil

Recoil is a relatively new state management library which is developed by Facebook, now called Meta. This modern approach introduces the concept of atoms and selectors. Atoms are individual state variables that components can subscribe to, and they automatically re-render the components when they get updated. Whereas selectors are pure functions that accept atoms or other selectors as input and return the output as a derived or computed state.

Pros of Recoil:

• With its selector functions, it provides built-in asynchronous support that helps manage async data without any additional middleware such as Saga or Redux Thunk.
• It provides a cleaner and concise application development codebases by eliminating the unnecessary amount of boilerplate code.
• The recoil hooks, such as useState and useCallBack, help you in managing and updating the state within the React Native application with less effort.

Cons of Recoil:

• As it's a relatively newer state management library, it has a smaller community when compared to others like Redux.
• It may lead to potential memory leaks and have less effective garbage collection when managing state.

Final Remarks

There is no one-size-fits-all state management library when it comes to choosing the right one between these - Redux, MobX, and Recoil. Redux is ideal for building large-scale apps that require a strict data flow and enhanced debugging. MobX, on the other hand, is preferred when you need a faster setup and prefer reactive programming. Lastly, Recoil is best used for apps that need both local and global state management with a minimal setup.

Partnering with a React Native app development company can help you embrace one of these state management libraries- Redux, MobX, and Recoil. A trusted app development partner will help you build an app that aligns well with your user expectations and long-term growth strategies.
