通过以上步骤,React Hook Async等待可以在承诺上保持渲染。当异步操作完成后,状态变量data将被更新,触发组件的重新渲染,并且可以在渲染中使用最新的数据。 React Hook Async等待的优势包括: 简化异步操作:使用async/await语法可以更清晰地编写异步代码,避免了回调地狱和Promise链的复杂性。

useAsync需要允许我们手动触发请求 想清楚需求,写代码就很方便了,自定义hook无非就是对基础版hook进行逻辑的组合加工 export const useAsync = (asyncFunction, auto = true) => { const [value, setValue] = useState(null) const [pending, setPending] = useState(false) const [error, setError] = useSta...
在React 中,除了 useEffect 外,接收「dependency array」的 hook 还有 useMemo、useCallback 和 useImperativeHandle。大部分情况下,使用「dependency array」确实可以节省一些性能的开销。我们刚刚也提到了,「dependency array」千万不要遗漏回调函数内部依赖的值。但如果 「dependency array」依赖了过多东西,可能导致代码...
