webpack4如何优化antd的大小

Question

这是依赖图，发现ant-design体积太大了，请问下该如何优化。

const webpack = require('webpack');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const TerserPlugin = require('terser-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const CleanWebpackPlugin = require('clean-webpack-plugin');
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;
const OptimizeCssAssetsPlugin = require('optimize-css-assets-webpack-plugin');
const ProgressBarPlugin = require('progress-bar-webpack-plugin');
const path = require('path');

module.exports = {
    optimization: {
        minimizer: [
            // 压缩js

    externals: {
        react: 'React',
        'react-dom': 'ReactDOM',
        redux: 'Redux',
        g2: 'G2',
        'g2-react': 'G2',
        'immutable': 'Immutable',
        'moment': 'moment'
    }
};

这是我的webpack配置
