get-state-patterns

Retrieve state management patterns for React Native Expo projects using Zustand with MMKV persistence. Learn store setup, selectors, and organization rules for global state.

Instructions

Get state management patterns (Zustand + MMKV). Call this when creating a store or working with global state. Covers Zustand store setup, MMKV persistence adapter, selectors, useShallow, getState() for outside React, and store organization rules. Use topic to get a specific section only.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`topic`	No	Get a specific section only. Available: zustand, mmkv, mmkv-adapter, store-pattern, selectors, use-shallow, get-state, organization. Omit for full content.
`compact`	No	If true, returns rules only without code examples. Much shorter.

Implementation Reference

src/content/patterns/state-patterns.ts:214-216 (handler)
The handler function that executes the `get-state-patterns` tool logic by calling the `resolvePattern` helper.
```

  resolvePattern(pattern, topic, compact);
```
