在React Typescript中是否可以將組件prop接口與另一個prop使用？

Question

基本上，我想要行injectComponentProps: object被動態綁定到injectComponent的prop接口。 在這種情況下，它將是injectComponentProps: InjectedComponentProps ，但我希望它是動態的。

即，一旦prop injectComponent被設置，injectComponentProps就被定義為injectComponent的組件props。

這可能嗎？

interface InjectedComponentProps {
  variant: string
  size: number
}

const InjectedComponent: React.FC<InjectedComponentProps> = (props) => {
  return <Text {...props}>hello</Text>
}

interface ComponentProps {
  injectComponent: React.ReactType
  injectComponentProps: object
}

const Component: React.FC<ComponentProps> = (props) => {
  const InjectedComponent = props.injectComponent
  return (
    <>
      <InjectedComponent {...props.injectComponentProps}/>
    </>
  )
}


const Main: React.FC = () => {
  return (
    <Component
      injectComponent={InjectedComponent}
      injectComponentProps={{ variant: 'footnote', size: 14 }}
    />
  )
}

Answer 1

interface InjectedComponentProps {
  variant: string
  size: number
}

const InjectedComponent: React.FC<InjectedComponentProps> = (props) => {
  return null
}

interface ComponentProps<T> {
  injectComponent: React.FC<T>
  injectComponentProps: T
}

const Component = <T extends {}>(props: ComponentProps<T>): JSX.Element => {
  const InjectedComponent = props.injectComponent
  return (
    <>
      <InjectedComponent {...props.injectComponentProps}/>
    </>
  )
}


const Main: React.FC = () => {
  return (
    <Component
      injectComponent={InjectedComponent}
      injectComponentProps={{ variant: 'footnote', size: 14 }}
    />
  )
}

您應該嘗試將ComponentProps修改為約束通用組件，而不是將類型簡單地聲明為object ，而是推斷其類型參數的props。

通用GetProps使用條件類型推斷從組件推斷道具，即推斷泛型的類型參數。

type GetProps<C extends React.ComponentType<any>> = C extends React.ComponentType<infer P> ? P : any

interface InjectedComponentProps {
  variant: string
  size: number
}

const InjectedComponent: React.FC<InjectedComponentProps> = (props) => {
  return <Text {...props}>hello</Text>
}

// make this a generic type
interface ComponentProps<C extends React.ComponentType<any>> {
  injectComponent: C
  injectComponentProps: GetProps<C>
}

// and use it here
const Component: React.FC<ComponentProps<typeof InjectedComponent>> = (props) => {
  const InjectedComponent = props.injectComponent
  return (
    <>
      <InjectedComponent {...props.injectComponentProps}/>
    </>
  )
}

const Main: React.FC = () => {
  return (
    <Component
      injectComponent={InjectedComponent}
      injectComponentProps={{ variant: 'footnote', size: 14 }}
    />
  )
}
