RxJS is a powerful library for reactive programming in JavaScript, providing a functional and reactive approach to handling asynchronous data streams. It allows developers to work with observables, which are like streams that can emit multiple values over time. RxJS offers a wide range of operators for transforming, filtering, and combining these streams, making it ideal for handling complex asynchronous operations.

Zustand is a minimalistic and straightforward state management library for React applications. It offers a simple and intuitive API for managing global state in a React component tree without the need for complex setups or boilerplate code. Zustand leverages React hooks and context under the hood to provide a lightweight yet powerful state management solution.

RxJS is a very popular library for reactive programming, especially in the JavaScript community. It has a large user base and is widely adopted by many developers. Zustand is also gaining popularity, particularly in the React community, but it is not as well-known or widely used as RxJS.


RxJS is a powerful library for reactive programming and provides a wide range of operators and utilities for managing complex asynchronous tasks and data streams. It is primarily used for handling event streams and managing complex state. Zustand, on the other hand, is a state management library specifically designed for React applications. It simplifies the process of managing state and provides a more intuitive API for handling state changes.

Integration with React

RxJS can be used with React, but it requires additional setup and integration. It is a separate library and may involve a steeper learning curve for developers new to reactive programming. Zustand, on the other hand, is built specifically for React and integrates seamlessly with React components. It provides a more straightforward and intuitive approach to state management within React applications.


RxJS is known for its performance optimizations and efficient handling of asynchronous operations. It offers fine-grained control over subscriptions and memory management. Zustand, being a minimalistic state management library, is also performant but does not have the same level of optimization as RxJS. However, for most small to medium-sized React applications, the performance difference may not be noticeable.

Learning Curve

RxJS has a steep learning curve, especially for developers who are new to reactive programming concepts. It requires understanding reactive streams, observables, and a variety of operators to effectively use the library. Zustand, on the other hand, has a much lower learning curve. It is designed to be beginner-friendly and has a simpler API that is easier to grasp, especially for React developers.

Community and Support

RxJS has a strong and active community, with plenty of resources, tutorials, and online support available. It has been around for a long time and is a trusted library for many developers. Zustand, while growing in popularity, has a smaller community and fewer resources available. However, it is backed by the creators of React Query and has good community support within the React ecosystem.
