实现 react 动态组件引用，支持vite与webpack

安装

yarn add @caixue/react-loadable 或者 npm install @caixue/react-loadable

用法

import Loadable from '@caixue/react-loadable';
import Loading from './my-loading-component';

const LoadableComponent = Loadable({
  loader: () => import('./my-component1'),
  loading: Loading,//自定义加载过程的展示组件
  timeout: 20000,//超时设置 默认10000
});//请在模块顶层保存加载组件

//或者使用以下简单方式（将会使用内置默认加载过程组件，如果html的lang属性为zh-CN，默认组件内部为中文描述，否则为英文。）
const LoadableComponent = Loadable(() => import('./my-component1'));
 
export default class App extends React.Component {
  render() {
    return <LoadableComponent/>;
  }
}

对于获取组件ref

• 通过 getRef 可以获取到组件ref.

//app.tsx
import Loadable from '@caixue/react-loadable';
import React, { useEffect, useRef } from 'react';
const MyInput = Loadable(() => import('./myInput'));

const App: React.FC = () => {
    const myInput = useRef() as React.MutableRefObject<React.ElementRef<typeof MyInput>>;
    useEffect(() => {
        myInput.current.getRef().then((input) => {
            input.current.focus();
        })
    })
    return <MyInput ref={myInput} />
}

export default App;

//myInput.tsx
import React, { forwardRef, useRef, useImperativeHandle } from 'react';

const MyInput = forwardRef((props, ref) => {
    const input = useRef<HTMLInputElement | null>();
    useImperativeHandle(ref, () => {
        return input;
    })
    return <input ref={(el) => { input.current = el }} />
})

export default MyInput;
