SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill automates the boilerplate for creating reusable React hooks, ensuring consistent interfaces, memoization patterns, and a clean export strategy with an index.ts.

Core Features & Use Cases

  • Boilerplate automation: Scaffold new hooks with a consistent structure, including option interfaces and a ready export.
  • Pattern library: Includes TypeScript interfaces, memoized callbacks, and a centralized index.ts export.
  • Use Case: Quickly build hooks for form state, API calls, or UI interactions and reuse them across components.

Quick Start

Create a new hook file under src/hooks (for example, src/hooks/useHookName.ts) following the provided template, and update src/hooks/index.ts to export the hook (e.g., export { useHookName } from './useHookName').

FAQPage Schema
How do I reduce duplicated hook logic across React components?

Extract shared hook logic into reusable custom hooks by defining TypeScript interfaces for options and return values, using useCallback for memoized callbacks, and exporting through a centralized index.ts file. This pattern eliminates duplication in form state, API calls, and UI interaction hooks across your codebase.

What's the best way to scaffold a new React hook with consistent structure?

Create a hook file under src/hooks following TypeScript interface patterns for options and return types, implement memoized callbacks via useCallback, then export it from src/hooks/index.ts. This ensures consistent module structure and reusability across your React application.

Can I use TypeScript with custom React hooks for type safety?

Yes. Define TypeScript interfaces for hook options and return values to enforce type safety. This approach works with any React setup and is essential for creating maintainable, reusable hooks that catch errors at compile time rather than runtime.

How do I refactor component logic into reusable hooks?

Identify repeated state management or side-effect patterns in components, extract them into a custom hook with memoized callbacks and TypeScript interfaces, then export via index.ts. This converts component-specific logic into hooks applicable to form handling, API integration, or UI state.

Why should I memoize callbacks in custom React hooks?

Memoizing callbacks via useCallback prevents unnecessary re-renders in child components and ensures stable function references across hook usage. This optimization is critical when custom hooks manage form state, API calls, or UI interactions passed as dependencies to other effects.
