# hooks-pattern

A skill that teaches your agent React Hooks and helps pull repeated stateful logic into custom hooks. Useful when components start duplicating behaviour.

## What it does

The skill activates on `**/*.tsx` and `**/*.jsx` files. Inside are instructions on `useState` for local state, `useEffect` for side effects, the Rules of Hooks, and custom hooks prefixed with `use`. It also argues against reaching for `useEffect` when a value can be computed in the component body, and suggests letting React Compiler handle memoization instead of hand-written `useMemo` and `useCallback`.

The details section compares hooks with class components: the constructor, `componentDidMount`, `componentWillUnmount`, binding methods with `bind`. Two common problems get a walkthrough — Higher Order Component and Render Props wrappers that pile up into wrapper hell, and tangled logic inside a growing class. Worth reading before you decide whether to rewrite an old component or leave it alone.

Tool access is limited to `Read`, `Grep` and `Glob`, so the skill reads code rather than editing it. It runs in a forked context, which keeps the walkthrough out of your main session. One caveat: this is React material, so on a project without React it does nothing for you.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add PatternsDev/skills --skill hooks-pattern -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/hooks-pattern/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/hooks-pattern/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add PatternsDev/skills --skill hooks-pattern -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/hooks-pattern/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add PatternsDev/skills --skill hooks-pattern -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/hooks-pattern/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install PatternsDev/skills hooks-pattern
```

2. **Manually: put the files in place**
- File: `.github/skills/hooks-pattern/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add PatternsDev/skills --skill hooks-pattern -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/PatternsDev/skills --path react/hooks-pattern
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/hooks-pattern/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add PatternsDev/skills --skill hooks-pattern -a opencode
```

## When to use it
- extract form handling into a reusable custom hook
- remove duplicated logic between `componentDidMount` and `componentWillUnmount`
- replace HOC and Render Props wrappers with hooks
- compute derived state without an extra `useEffect`
- convert a class component into a function component with hooks

## Example prompts
- help me move the resize subscription logic into a useWindowWidth custom hook
- look at this component and tell me where the useEffect is unnecessary
- rewrite this class Button as a function component with useState

# Hooks Pattern

## Table of Contents

- [Source](#source)

React 16.8 introduced a new feature called [**Hooks**](https://react.dev/reference/react/hooks). Hooks make it possible to use React state and lifecycle methods, without having to use an ES2015 class component.

Although Hooks are not necessarily a design pattern, Hooks play a very important role in your application design. Many traditional design patterns can be replaced by Hooks.

## When to Use

- Use this when you need to add state or lifecycle behavior to functional components
- This is helpful for extracting and reusing stateful logic across multiple components
- Use this instead of class components for cleaner, more composable code

## Instructions

- Use `useState` for local state and `useEffect` for side effects in functional components
- Create custom hooks (prefixed with `use`) to encapsulate and share reusable logic
- Follow the Rules of Hooks: only call hooks at the top level and only in React functions
- Avoid unnecessary `useEffect` — compute derived state directly in the component body
- Let the React Compiler handle memoization instead of manual `useMemo`/`useCallback` where possible

## Details

### Class components

Before Hooks were introduced in React, we had to use class components in order to add state and lifecycle methods to components. A typical class component in React can look something like:

```js
class MyComponent extends React.Component {
  /* Adding state and binding custom methods */
  constructor() {
    super()
    this.state = { ... }

    this.customMethodOne = this.customMethodOne.bind(this)
    this.customMethodTwo = this.customMethodTwo.bind(this)
  }

  /* Lifecycle Methods */
  componentDidMount() { ...}
  componentWillUnmount() { ... }

  /* Custom methods */
  customMethodOne() { ... }
  customMethodTwo() { ... }

  render() { return { ... }}
}
```

A class component can contain a state in its constructor, lifecycle methods such as `componentDidMount` and `componentWillUnmount` to perform side effects based on a component's lifecycle, and custom methods to add extra logic to a class.
