react组件库添加typescript类型提示 为react组件库添加typescript类型提示的方法

all2005 人气:0

以我自己的组件react-better-countdown为例,

首先在package.json里面添加types: types/index.d.ts


然后文件目录上添加对应文件夹和文件,


最后是index.d.ts文件的编写,具体看代码:

import * as React from 'react';

interface CountdownProps {
  count?: number;
  dayText?: string | React.ReactElement;
  hourText?: string | React.ReactElement;
  minuteText?: string | React.ReactElement;
  secondText?: string | React.ReactElement;
  callback?: Function;
  className?: string;
  style?: React.CSSProperties;
  rest?: any
}

interface CountdownState {
  count?: number;
}

declare module 'react-better-countdown' {
  export default class Countdown extends React.Component<CountdownProps, CountdownState> {
    state: CountdownState;
    timer: null | number;
    tick: () => void;
    componentDidMount(): void;
    componentDidUpdate(prevProps: CountdownProps): void;
    componentWillUnmount(): void;
    render: () => React.ReactElement;
  }
}
