webpack 如何同时输出压缩和未压缩的文件的实现步骤

const path = require('path')

const isMinify = process.env.MINIFY

/**
 * @type {import('webpack').Configuration}
 */
const config = {
 entry: {

  index: './src/index.js'
 },
 output: {
  filename: isMinify ? '[name].min.js' : '[name].js',
  path: path.join(__dirname, 'dist')
 },
 devtool: 'cheap-source-map',
 optimization: {
  minimize: isMinify ? true : false
 }
}

module.exports = config

 "scripts": {
  "test": "echo \"Error: no test specified\" && exit 1",
  "build:min": "MINIFY=1 webpack --config=webpack.config.js",
  "build": "webpack --config=webpack.config.js"
 }

const path = require('path')
const UnminifiedWebpackPlugin = require('unminified-webpack-plugin');

/**
 * @type {import('webpack').Configuration}
 */
const config = {
 entry: {
  index: './src/index.js',
 },
 output: {
  filename: '[name].min.js',
  path: path.join(__dirname, 'dist')
 },
 devtool: 'cheap-source-map',
 plugins: [
  new UnminifiedWebpackPlugin({})
 ]
}

module.exports = config

const path = require('path')
const TerserWebpackPlugin = require('terser-webpack-plugin');

/**
 * @type {import('webpack').Configuration}
 */
const config = {
 entry: {
  index: './src/index.js',
  'index.min': './src/index.js'
 },
 output: {
  filename: '[name].js',
  path: path.join(__dirname, 'dist')
 },
 devtool: 'cheap-source-map',
 optimization: {
  minimize: true,
  minimizer: [
   new TerserWebpackPlugin({
    include: /min/,
    sourceMap: true
   })
  ]
 }
}

module.exports = config
