State Management

What it does

This skill assists in selecting and implementing appropriate state management solutions when building frontend user interfaces. It provides guidance on choosing between various approaches like Zustand, React Query, React Router, React Hook Form, useState, and useReducer based on specific needs such as managing global state, persisting data across navigation, sharing data between components, or handling form state. The skill offers quick references and a decision tree to aid in this selection process.

When to use it

• When deciding how to manage global application state.
• To determine the best approach for persisting UI state during page navigation.
• For selecting a method to share data between different components within your frontend application.
• When needing help distinguishing between server-side data (requiring React Query) and local component state (suitable for useState/useReducer).

Key capabilities

• Decision Tree: Provides a visual guide to select the appropriate state management solution based on use case.
• Quick Reference: Offers links to documentation for actions like reading from Zustand stores, persisting state, and fetching server data with React Query.
• Guidance on State Management Libraries: Covers considerations for using Zustand, React Query, React Router, React Hook Form, useState, and useReducer.
• Detailed Rules: Provides access to a rules/ directory containing more in-depth guidance (not detailed here).

Example prompts

• "What's the best way to manage global state in my application?"
• "Should I use React Query or Zustand for this data?"
• "How do I persist state across page navigations?"
• "I need to share some data between two components, what’s the recommended approach?”

Tips & gotchas

• This skill is specifically designed for frontend development and UI workflows.
• The "rules/" directory contains more detailed guidance that may be helpful after initial selection.
• It focuses on choosing a state management solution; it doesn't provide implementation details for each library beyond the quick reference links.
