有没有大佬帮忙看看

const { resolve } = require('path') const { ESBuildPlugin } = require('esbuild-loader') const VueLoaderPlugin = require('vue-loader/lib/plugin')  const { createTemplatePlugin } = require('./template.plugin.cjs')  const entry = {     app: './src/app.js',     bpp: './src/bpp.js', }  const templatePlugins = Object.keys(entry).map(it => createTemplatePlugin({     chunks: [it],     filename: `${it}.html`, }))  const config = {     module: {         rules: [             {                 test: /.vue$/,                 loader: 'vue-loader',                 exclude: /node_modules/,             }, {                 test: /.js$/,                 use: [{                     loader: 'esbuild-loader',                     options: {                         target: 'es2015'                     }                 }],                 exclude: /node_modules/,             }, {                 test: /.(png|jpg|jpeg|gif)$/,                 use: [{ loader: 'file-loader', options: { outputPath: 'assets' } }],             }, {                 test: /.(css|less)$/,                 use: [                     { loader: 'style-loader' },                     { loader: 'css-loader' },                     { loader: 'less-loader' },                 ],                 exclude: /node_modules/             }         ]     },     resolve: {         extensions: ['.vue', '.js']     },     plugins: [         new VueLoaderPlugin(),         new ESBuildPlugin(),         ...templatePlugins,     ],     optimization: {         splitChunks: {             chunks: 'all',             automaticNameDelimiter: '_',         },     },     entry,     output: {         filename: '[name].[chunkhash].js',         chunkFilename: '[name].[chunkhash].js',         path: resolve(__dirname, 'dist')     },     mode: 'development', }  module.exports = config
