Splitting State into Slices
As your React applications grow, managing all your state in a single store can quickly become hard to maintain. To help organize complex state, Zustand supports the slice pattern. This pattern lets you split your state into smaller, logical pieces called slices. Each slice handles its own part of the state and related actions. By breaking your store into slices, you keep your code modular, easier to reason about, and more scalable as your app grows.
To implement the slice pattern in Zustand, you define each slice as a function that returns its state and actions. Then, you combine these slices when creating your store. For instance, imagine an app that manages both user authentication and a list of todos. You might define a userSlice for authentication state and a todoSlice for the todo logic. These slices are then merged into one store, so you can access and update all parts of your state from a single source while keeping the logic for each feature separate. This approach makes it much easier to scale your Zustand store as your application adds new features or teams work on different parts of the app.
