如何描述toppy接受打字稿将正确使用的所有子项的包装器?

import Tippy, { TippyProps } from '@tippy.js/react'
import React from 'react'
import 'tippy.js/dist/tippy.css'

Tippy.defaultProps = {
  maxWidth: '500px',
}

export const Tooltip: Tooltip = ({ children, content, ...rest }) => {
  if (!children) return null
  if (!content) return children

  return (
    <Tippy content={content} {...rest}>
      {children}
    </Tippy>
  )
}

interface Tooltip {
  (props: MyProps): React.ForwardRefExoticComponent<TippyProps> | null | React.ReactNode
}

interface MyProps {
  content?: string | React.ReactNode
  children?: React.ReactNode
}

像这样使用:

   <Tooltip content='Text'>
        <div>123</div>
   </Tooltip>

打字稿给我孩子在return语句中的错误:

  

键入“字符串|编号真实| {} | ReactElement ReactElement   组件)> | null)| (新(道具:任意)=>   组件)> | ReactNodeArray | ReactPortal'不是   可分配给'ReactElement类型   ReactElement组件)> | null)| (新(道具:任意)=>组件)>'。类型'string'不能分配给类型'ReactElement ReactElement Component)> | null)| (新(道具:任意)   =>组件)>'。ts(2322)index.d.ts(6,3):预期的类型来自属性'children',该属性在此声明为type   'IntrinsicAttributes&TippyProps'

答案 0 :(得分:1)

该错误将您正确地指向了问题:您已将子级声明为ReactNode,但ReactNode可以是字符串,而Tippy(显然)将不接受字符串子级。使用ReactElement代替。在调试像这样的打字稿错误时,添加空白格式通常会很有帮助(至少直到您习惯于阅读它们为止):

Type 
'string | number | true | {} | ReactElement ReactElement Component)> | null) 
| (new (props: any) => Component)> 
| ReactNodeArray 
| ReactPortal' 
is not assignable to type 
'ReactElement ReactElement Component)> | null) 
| (new (props: any) => Component)>'

Type 'string' is not assignable to type 
'ReactElement ReactElement Component)> | null) 
| (new (props: any) => Component)>'

ts(2322) index.d.ts(6, 3): The expected type comes from property 'children' 
which is declared here on type 'IntrinsicAttributes & TippyProps'
