zustand-slices-pattern-for-scalability

What problem does it solve?

Divide complex Zustand stores into feature-focused slices to improve maintainability and collaboration. This pattern encourages splitting large stores into modular slices, composing them into a root store, and enabling cross-slice actions.

Core Features & Use Cases

• Slice-based state organization: Define slices as StateCreator functions that return a portion of the store.
• Multi-slice composition: Combine slices into a RootStore and expose a typed hook for consuming the full state.
• Cross-slice communication: Access other slices via get() for shared data or dependent actions.
• Type-safe interfaces and selective persistence: Provide interfaces per slice and enable per-slice persistence strategies.

Quick Start

Create and use a root store by composing individual slices with their StateCreator types and exposing a typed hook for components.
