在TypeScript中,你可以使用泛型和接口来定义组件的children属性。例如: 代码语言:txt 复制 import React from 'react'; interface MyComponentProps { // 其他属性... children?: React.ReactNode; // 使用React.ReactNode来表示children可以是任何React节点 } const MyComponent: React.FC<...
React Children with TypeScript September 23, 2020 reacttypescriptThe React children prop allows components to be composed together and is a key concept for building reusable components. Visually, we can think of it as a hole in the component where the consumer controls what is rendered. This po...

Declaring thechildrenprop asReactNodeis a perfectly viable option, but if you want to trim your code even further, you can useReact.FC.React.FCis a standard type for components written using the arrow function. As you probably guessed,FCstands for “Functional Component. " React.FC React.FCa...
Let's jump right into it and have a look at the previous example as a class component in TypeScript. importReact,{Component}from'react';interfaceTitleProps{title:string;subtitle?:string;}classTitleextendsComponent<TitleProps>{render(){const{title,subtitle,children}=this.props;return(<><h1>{tit...
例如,获取props中的id,需要在 componentDidMount和 componentDidUpdate 中同时定义;监听函数也需要在 componentDidMounted和componentWillUnmount中监听和注销 3.react组件一直是函数,使用Hook完全拥抱函数 ## State Hook 新建一个likeBotton.tsx 文件【点赞按钮】 ...
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> ...
第一种:也是比较推荐的一种,使用 React.FunctionComponent,简写形式:React.FC: // Great type AppProps = { message: string } const App: React.FC<AppProps> = ({ message, children }) => ( <div> {message} {children} </div> ) 复制代码 ...
TypeScript + React 类型安全三件套:Component、Redux、和Service 类型化。 Component 类型化 首先安装 React 类型依赖: // React源码改为TypeScript之前都要手动安装这些类型依赖 npm i -D @types/react @types/react-dom 基础类型 组件泛型 React.ComponentType<P> = React.ComponentClass<P> | React.FunctionCo...
type IProps = { name: string; age: number; }; <MyComponent<IProps> name="React" age={18} />; // Success <MyComponent<IProps> name="TypeScript" age="hello" />; // Error 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.
