interfaceMyComponentProps { name:string; age:number; } Define FC with Props interface With the Props interface defined, we can now use it to define our FC. We’ll use the FC type and pass in our Props interface as a generic type argument. For example: constMyComponent:FC<MyComponentProps...
function renderApplication<Props: Object>( RootComponent: React.ComponentType<Props>, initialProps: Props, rootTag: any, WrapperComponent?: ?React.ComponentType<*>, fabric?: boolean, showFabricIndicator?: boolean, ) { invariant(rootTag, 'Expect to have a valid rootTag, instead got ', rootTag...
除此之外,函数类型还可以使用React.FunctionComponent<P={}>来定义,也可以使用其简写React.FC<P={}>,两者效果是一样的。它是一个泛型接口,可以接收一个参数,参数表示props的类型,这个参数不是必须的。它们就相当于这样: type React.FC<P = {}> = React.FunctionComponent<P> 最终的定义形式如下: interface ...
React Router provides various methods to access route parameters, depending on the component’s type and the specific use case. In functional components, we can access route parameters using the useParams hook provided by React Router. Let’s continue with our previous example of the blog ...
What about `React.FunctionComponent`/`React.VoidFunctionComponent`? You may see this in many React+TypeScript codebases: const App: React.FunctionComponent<{ message: string }> = ({ message }) => ( {message} ); However, the general consensus today is that React.FunctionComponent (or ...

Sometimes you may have conflicts, perhaps with Next.js'Linkrouter component. In that case, you can alias your imports: import{LinkasDSLink}from"@nypl/design-system-react-components";import{Link}from"next/link";functionNewComponent(props){return(<DSLinkas={Link}type="action"href="#">Next Page...
