Constate is a JavaScript library that provides an easy way to create and consume context in React. It helps manage application state by enabling you to define context and its associated reducers in one place. With constate, you can create reusable and composable state management logic that can be used across multiple components and even across different React applications.

Alternatives: redux, MobX, React context API

Valtio is a state management library for React applications. It provides a simple and efficient way to manage and share state across components without the need for complex setup or boilerplate code. Valtio leverages the power of ES6 Proxies to create reactive state objects that automatically update components when the state changes.

Both Constate and Valtio are relatively popular npm packages in the React ecosystem. Constate has gained a significant amount of popularity due to its simplicity and ease of use. Valtio, on the other hand, has been gaining momentum for its unique approach to state management.


Constate is a state management solution that specializes in creating reusable React state containers. It provides a simple API to define state and uses React's useContext hook for state management. Valtio, on the other hand, is a small, standalone library that offers reactive state management with minimal boilerplate. It leverages ES6 Proxies for automatic reactivity and provides a straightforward and intuitive API for managing and observing state.

Developer Experience

Constate offers a very developer-friendly experience with its simplicity and familiarity to React developers. It is easy to understand and integrate into existing React projects. Valtio, on the other hand, introduces a different paradigm with its reactive state management, which may require a small learning curve for those not familiar with reactive programming. However, Valtio's API is still intuitive and straightforward to use.


Both libraries are designed to be performant. Constate relies on React's built-in useContext hook, which is optimized for performance. It leverages React's diffing algorithm to update only the components that depend on the changed state. Valtio, on the other hand, utilizes ES6 Proxies to achieve reactivity, which can introduce a small overhead. However, Valtio's reactivity is highly optimized and performs well even with large state objects.

Integration with React Ecosystem

Both Constate and Valtio integrate well with the React ecosystem. They can be used alongside other React libraries and frameworks without any issues. Constate's simple API makes it easy to integrate into existing projects, while Valtio's reactive state management can be a powerful addition to more complex React applications.

Community and Maintenance

Both packages have active communities and are actively maintained. Constate has been around for a longer time and has a larger community, while Valtio is newer but is gaining popularity quickly. Both libraries receive regular updates and bug fixes, ensuring their stability and compatibility with the latest versions of React.
