Recoiljs vs Zustand: What are the differences?

# Introduction

Key differences between Recoiljs and Zustand are:

1. **Data management approach**: Recoiljs offers a more global state management approach, with atoms, selectors, and the ability to share state across multiple components seamlessly. On the other hand, Zustand focuses on a more lightweight and decentralized approach, allowing each component to have its own state independent of others.

2. **Developer experience**: Recoiljs has a stronger tooling ecosystem with built-in dev tools, selectors for deriving state, and a familiar React-like API. Zustand, on the other hand, prides itself on having a minimal API surface and being easy to learn and use without the need for additional tooling.

3. **Performance optimizations**: Recoiljs comes with features like asynchronous selectors, batching updates, and built-in memoization for optimized performance. Zustand, while not lacking in performance, maintains a simpler approach without these advanced optimizations.

4. **Community and ecosystem**: Recoiljs is backed by Facebook and has a larger community and ecosystem, with more libraries, tooling, and resources available. On the other hand, Zustand, being a newer library, is growing in popularity but still has a smaller community and ecosystem compared to Recoiljs.

5. **Ease of integration**: Recoiljs seamlessly integrates with existing React components and patterns due to its close ties with React. Zustand, while also built for React, offers a more standalone approach that can be integrated with other frameworks or vanilla JavaScript applications more easily.

6. **State immutability**: Recoiljs encourages the use of immutable state updates, making it easier to reason about changes and preventing common bugs. In contrast, Zustand allows for mutable state updates by design, providing developers with the flexibility to choose their approach based on the project requirements.

# Summary

In summary, Recoiljs focuses on a global state management approach with advanced optimizations, strong tooling, and a larger community, while Zustand offers a lightweight, decentralized approach with minimal API surface, ease of integration, and flexibility in state handling.
