Usage

In your webpack configuration (webpack.config.js):

const EntryChunkWebpackPlugin = require('entry-chunk-webpack-plugin');
const LibraryExtendWebpackPlugin = require('library-extend-webpack-plugin');

module.exports = {
    mode: "production",
    entry: {
        example: './src/index.ts',
    },
    output: {
        library: "LIB",
        libraryTarget: "umd",
        filename: '[name].js'
    },
    //...
    plugins: [
        new EntryChunkWebpackPlugin({
            chunkConfig: [{
                name: 'example.base',
            }, {
                name: 'example.extend',
                modules: ['RichEditor', 'ReactCropper']
            }],
        }),
        new LibraryExtendWebpackPlugin({
            exclude: function (fileName) {
                return !/\.[tj]s$/i.test(fileName) || /example(\.base)*(\.min)*\.js/.test(fileName);
            }
        }),
    ]
}

Entry File: index.ts

export { default as Avatar } from './components/avatar/index';

export { default as Button } from './components/button/button';

export { default as RichEditor } from './components/rich-editor/index';

export { default as ReactCropper } from './components/react-cropper/index';

Output Bundle

It will output 3 files

example.js ({ Avatar, Button, RichEditor, ReactCropper })
example.base.js ({ Avatar, Button })
example.extend.js ({ RichEditor, ReactCropper })

Avatar and Button will be packaged to example.base.js.
RichEditor and ReactCropper will be packaged to example.extend.js.

Function Avatar, Button, RichEditor and ReactCropper are added to global library LIB.
And LIB.Avatar, LIB.Button, LIB.RichEditor and LIB.ReactCropper work well.

Options

mode

Its value can be 'add' or 'replace' or ''. The default value is add.

'add': means will add chunk file to entry.
'replace': means will remove original entry file, and add chunk file to entry.
'': means will not add chunk file to entry.

min

Its value must be boolean or 'both'. The default value is false.

true: it will add [name].min.js to entry.
false: it will add [name].js to entry.
'both': it will both add [name].js and [name].min.js to entry.

chunkConfig

Its value must be Array. You need to config it to split entry file into multiple files as example.

exclude

You can skip entry file by exclude: ({name, path}) => boolean

Example of usage on the Browser

In the browser:

<script src="https://cdn.xx.com/example.base.js"></script>
<script src="https://cdn.xx.com/example.extend.js"></script>

If you do not use the module (RichEditor and ReactCropper) in example.extend.js, you can only add example.base.js to html. Because in the example, library-extend-webpack-plugin is used to package example.extend.js into an extension library.

<script src="https://cdn.xx.com/example.base.js"></script>
