What's State Management Libraries for React?

State management libraries are essential tools in React applications to handle the complexity of managing application state. They provide structured ways to manage and share state across components, making it easier to build scalable and maintainable applications. Each library offers unique approaches and features tailored to different use cases, from simple state management to complex asynchronous flows. Understanding the differences among these libraries helps developers choose the right tool for their specific needs and application architecture.

Feature Comparison: react-redux vs mobx-react vs redux-saga

State Management Approach

  • react-redux:

    React-Redux follows a unidirectional data flow and uses a centralized store to manage application state. Components subscribe to the store and receive updates through the connect function or hooks like useSelector, ensuring a predictable state management pattern that is easy to debug and test.

  • mobx-react:

    MobX-React utilizes observable state and reactions to automatically update the UI when the state changes. This reactive programming model allows for a more intuitive and less verbose way to manage state, as components automatically re-render when observable data they depend on changes.

  • redux-saga:

    Redux-Saga uses generator functions to handle side effects in a more manageable way. It allows you to write asynchronous code that looks synchronous, making it easier to handle complex flows, such as API calls and background tasks, while keeping your components clean and focused on rendering.

Learning Curve

  • react-redux:

    React-Redux has a moderate learning curve due to its reliance on the Flux architecture and concepts like actions, reducers, and middleware. While it may require more initial setup, it provides a structured approach that can be beneficial for larger applications.

  • mobx-react:

    MobX-React has a relatively gentle learning curve, especially for those familiar with JavaScript and React. Its declarative nature and less boilerplate code make it easier to grasp, allowing developers to quickly implement state management without extensive setup.

  • redux-saga:

    Redux-Saga has a steeper learning curve compared to the other two due to its use of generator functions and the complexity of managing side effects. However, once mastered, it offers powerful capabilities for handling complex asynchronous flows.

Performance

  • react-redux:

    React-Redux optimizes performance through a subscription model that minimizes unnecessary re-renders. By using selectors and memoization, it ensures that components only re-render when the specific pieces of state they depend on change, making it suitable for larger applications.

  • mobx-react:

    MobX-React is designed for performance with its fine-grained reactivity. It only re-renders components that directly depend on changed observables, making it efficient for applications with dynamic data. This can lead to improved performance in scenarios with frequent state updates.

  • redux-saga:

    Redux-Saga can introduce some overhead due to its generator functions, but it excels in managing complex asynchronous flows without cluttering the component logic. Properly implemented sagas can lead to better performance in handling side effects, especially in applications with heavy API interactions.

Extensibility

  • react-redux:

    React-Redux is built on top of Redux, which has a rich ecosystem of middleware and extensions. This makes it highly extensible, allowing developers to enhance functionality with tools like Redux Thunk or Redux Logger, catering to different application needs.

  • mobx-react:

    MobX-React is highly extensible and can be easily integrated with other libraries and frameworks. Its simplicity allows developers to adopt it incrementally, making it a flexible choice for various project sizes and complexities.

  • redux-saga:

    Redux-Saga is also extensible, allowing developers to create custom sagas and effects. Its generator-based approach provides a powerful way to manage complex asynchronous logic, making it suitable for applications that require intricate side effect management.

Community and Ecosystem

  • react-redux:

    React-Redux benefits from a large community and a mature ecosystem. It is widely adopted in the React community, which means there are numerous resources, tutorials, and third-party libraries available to assist developers in implementing state management effectively.

  • mobx-react:

    MobX-React has a growing community and ecosystem, though it is smaller compared to Redux. It has sufficient resources and documentation to support developers, but may not have as many third-party libraries or middleware options available.

  • redux-saga:

    Redux-Saga has a dedicated community and is well-documented, with many resources available for learning and troubleshooting. Its unique approach to handling side effects has led to a variety of patterns and best practices that are widely shared within the community.

How to Choose: react-redux vs mobx-react vs redux-saga
  • react-redux:

    Choose React-Redux if you need a predictable state container that follows the Flux architecture. It is suitable for larger applications where state management needs to be centralized and where you want to take advantage of middleware for side effects and asynchronous actions.

  • mobx-react:

    Choose MobX-React if you prefer a more straightforward and less boilerplate-heavy approach to state management. It is ideal for applications that require reactive programming and want to leverage observables for automatic UI updates without much configuration.

  • redux-saga:

    Choose Redux-Saga if your application involves complex asynchronous operations and side effects. It provides a powerful way to handle side effects using generator functions, making it easier to manage complex flows and interactions with APIs.

Installation

Create a React Redux App

The recommended way to start new apps with React and Redux is by using our official Redux+TS template for Vite, or by creating a new Next.js project using Next's with-redux template.

Both of these already have Redux Toolkit and React-Redux configured appropriately for that build tool, and come with a small example app that demonstrates how to use several of Redux Toolkit's features.

# Vite with our Redux+TS template
# (using the `degit` tool to clone and extract the template)
npx degit reduxjs/redux-templates/packages/vite-template-redux my-app

# Next.js using the `with-redux` template
npx create-next-app --example with-redux my-app

An Existing React App

React Redux 8.0 requires React 16.8.3 or later (or React Native 0.59 or later).

To use React Redux with your React app, install it as a dependency:

# If you use npm:
npm install react-redux

# Or if you use Yarn:
yarn add react-redux

You'll also need to install Redux and set up a Redux store in your app.

This assumes that you’re using npm package manager with a module bundler like Webpack or Browserify to consume CommonJS modules.

If you don’t yet use npm or a modern module bundler, and would rather prefer a single-file UMD build that makes ReactRedux available as a global object, you can grab a pre-built version from cdnjs. We don’t recommend this approach for any serious application, as most of the libraries complementary to Redux are only available on npm.
