What is Zustand?

Zustand is a small, fast state management library for React applications. Its minimal API makes it easy to learn and requires no boilerplate code.

Unlike Redux, Zustand does not require you to define actions and reducers. You write functions that directly update the store.

Creating a Store

To create a store with Zustand, you use the create function. You define your store with state and functions that update it.

Using your store in React components is as simple as calling it like a custom hook.

Using in Components

Using a Zustand store in React components is straightforward. You can select the state you need from the store and prevent unnecessary re-renders.

Middleware and Extensibility

Zustand is easily extensible through its middleware support. You can persist state to localStorage with the persist middleware and use Redux DevTools with devtools.

Zustand in Large Projects

Zustand works well in large projects. You can split your stores logically using slices to make them more manageable. TypeScript support is also excellent.
