Zustand and Redux Toolkit (RTK) are both popular state management libraries for React applications. However, there are some key differences between the two libraries that may make Zustand a better choice for some applications.

Size and simplicity

Zustand is a lightweight library, with a file size of only a few kilobytes (KB), whereas Redux Toolkit (RTK) is considerably larger, often in the megabyte (MB) range. This size distinction makes Zustand an attractive option for applications that prioritise minimal file size and optimal performance.

Ease of use

Zustand is also much easier to use than RTK. Zustand provides a simple API for managing state, while RTK requires more configuration and setup. This makes Zustand a good choice for beginners and developers who are looking for a simple and easy-to-use state management library.

Performance

Zustand is also faster than RTK in most cases. This is because Zustand uses a simpler state management model and does not require as much boilerplate code.

Flexibility

Zustand is also more flexible than RTK. Zustand does not have a strict set of rules or conventions, which makes it more flexible and customizable.

When to use Zustand

Zustand is a good choice for applications where:

• Size and performance are important
• Simplicity is important
• Flexibility is important

Examples of applications where Zustand might be a good choice include:

• Small to medium-sized applications
• Simple applications
• Applications with a lot of state
• Applications with complex state transitions

When to use Redux Toolkit

Redux Toolkit is a good choice for applications where:

• Complexity is needed
• Scalability is needed
• Support for multiple users and other Redux libraries is needed

Examples of applications where Redux Toolkit might be a good choice include:

• Large and complex applications
• Real-time applications
• Applications with multiple users
• Applications that need to integrate with other Redux libraries

Summary

Here is a table summarising the key differences between Zustand and RTK:

Conclusion

Zustand and Redux Toolkit are both powerful state management libraries for React applications. The best library for you will depend on the specific needs of your application. If you are looking for a simple and easy-to-use library that is fast and scalable, then Zustand is a good choice. If you need a more advanced library with support for multiple users and other Redux libraries, then RTK is a good choice.

Additional benefits of using Zustand

In addition to the key differences listed above, Zustand also offers some other benefits, such as:

• Immutability by default: Zustand uses immutable state by default, which makes it easier to reason about and debug your code.
• DevTools support: Zustand supports React DevTools, which makes it easier to inspect and debug your state.
• TypeScript support: Zustand has full TypeScript support, which makes it easy to write type-safe code.

Overall, Zustand is a good choice for developers who are looking for a small, simple, fast, and flexible state management library.
