npm发布组件库怎么配置webpack？

Question

这是我的webpack配置

// 导入处理路径的模块
const path = require('path');
const webpack = require("webpack");

// 导出一个配置对象，将来webpack在启动的时候，会默认来查找webpack.config.js，并读取这个文件中导出的配置对象，来进行打包处理
module.exports = {
    // 项目入口文件
    entry: path.resolve(__dirname, 'src/main.ts'),
    // 项目输出文件
    output: {
        filename: 'bundle.js',
        libraryTarget: "umd", // 不用省略
        path: path.resolve(__dirname, 'dist'),
    },
    resolve: {
        extensions: ['.tsx', '.ts', '.js', '.json'],
    },
    // 文件处理规则
    module: {
        rules: [{
                test: /.(ts|js)x?$/,
                loader: 'babel-loader',
                exclude: /node_modules/
            },
            {
                test: /.(ts|tsx)$/,
                loader: "ts-loader",
            },
            {
                test: /.css$/,
                use: [{
                        loader: "style-loader",
                    },
                    {
                        loader: 'css-loader',
                    }
                ],
            },
            {
                test: /.(png|jp(e*)g|svg)$/,
                use: [{
                    loader: 'url-loader',
                    // 降低loader版本，启用CommonJS模块语法
                    options: {
                        esModule: false
                    }
                }]
            },
            {
                test: /.less$/,
                use: [{
                        loader: 'style-loader', // 从JS字符串创建样式节点
                    },
                    {
                        loader: 'css-loader', // 将CSS转换为CommonJS
                        options: {
                            modules: {
                                //生成随机类名
                                localIdentName: "cosmo-[local]-[hash:5]"
                            }, //开启css模块化
                        },
                    },
                    {
                        loader: 'less-loader', // 编译less为CSS


                    },
                ],
            }
        ]

    },
    externals: [{
        lodash: '_',
        react: 'react',
        antd: 'antd',
    }, ],
    optimization: {},
    // 插件
    plugins: []
}

这是我的入口文件

import Main from "./index.tsx"
export  {
  Main
} 

发布后获取不到我的组件只能用 export default Main才行，但是我想要的是那种 import {Button,List} from "antd"这种形式的也就是多组件库发布，应该怎么配置呢？请教诸位大神

项目中要安装babel-plugin-import插件，要配置babel.config.js。组件库的每一个组件要分别导出成单个文件。你看看插件的文档，就知道它干了什么了
