umd-package-loader

intro

tnpm i umd-package-loader --save

import Loader from 'umd-package-loader';
const LazyLoadComponent = (): JSX.Element => {
  const [com, setCom] = React.useState(null)
  React.useEffect(() => {
    new Loader({
      url: 'https://xxx.js',
      name: 'xxx', // library name e.g. xxxCom
    }).loadScript().then(component => {
      const node = component.default;
      setCom(React.createElement(node))
    }).catch(err => {
      // dosomething
    })
  }, []);

  return com
}

support requirejs，When the page has requirejs, it will be loaded in the way of require.if not, will use document.createElement('script') load script.

be careful, must follow commonjs or amd standard, forever, umd better. e.g. webpack config

module.exports = {
  devtool: 'source-map',
  entry: {
    reactDemo: resolve(__dirname, '../appGrounds/react/index.tsx')
  },
  output: {
    library: "xxxCom", // moduleName, the loader prop
    libraryTarget: 'umd', // must
    filename: '[name].js',
    path: resolve(__dirname, '../entry/lib'),
  }
}
