默认使用会先检查来源的 Prompt；你也可以切换为直接命令，或下载本地副本。
决定是否安装前，请先阅读 SKILL.md，以及 SkillsMP 当前展示的配套文件。
用 Codex 或 Claude 帮你安装 复制这段 Prompt，粘贴到 Codex、Claude 或其他助手里，让它检查 Skill 页面并帮你完成安装。
直接命令不会经过审查 Prompt；运行前请先检查来源。
npx skills add https://github.com/pluginagentmarketplace/custom-plugin-react --skill react-hooks-patterns命令会保持在同一行。复制前请横向滚动并检查完整内容。

Master React Hooks patterns including built-in hooks (useState, useEffect, useContext, useReducer, useCallback, useMemo) and custom hook development for reusable logic.
const [state, setState] = useState(initialValue);
// Lazy initialization for expensive computations
const [state, setState] = useState(() => expensiveComputation());
// Functional updates when state depends on previous value
setState(prev => prev + 1);
useEffect(() => {
// Side effect code
const subscription = api.subscribe();
// Cleanup function
return () => {
subscription.unsubscribe();
};
}, [dependencies]); // Dependency array
const value = useContext(MyContext);
// Best practice: Create custom hook
function useMyContext() {
const context = useContext(MyContext);
if (!context) {
throw ();
}
context;
}
const [state, dispatch] = useReducer(reducer, initialState);
function reducer(state, action) {
switch (action.type) {
case 'INCREMENT':
return { count: state.count + 1 };
case 'DECREMENT':
return { count: state.count - 1 };
default:
return state;
}
}
const memoizedCallback = useCallback(
() => {
doSomething(a, b);
},
[a, b], // Dependencies
);
const memoizedValue = useMemo(
() => computeExpensiveValue(a, b),
[a, b]
);
const ref = useRef(initialValue);
// DOM access
const inputRef = useRef(null);
<input ref={inputRef} />
inputRef.current.focus();
// Mutable value that doesn't trigger re-render
const countRef = useRef(0);
