Webpack使文件更大

Question

我目前在webpack上遇到一个问题，即“压缩”文件至原始大小的几倍。我不记得以前发生过这个问题，但是我似乎无法弄清楚我为介绍此问题所做的更改。

我哪里出错了？

原文：

export function updateFormAction() {
  const formEl: HTMLElement | null = document.getElementById("330545");
  if (formEl) {
    formEl.setAttribute('action','https://sis.tfaforms.net/330542');
  }
  else {
    throw new Error('Unable to find element 330545');
  }
}

Webpack“已缩小”：

!(function(e) {
  var t = {};
  function n(r) {
    if (t[r]) return t[r].exports;
    var o = (t[r] = { i: r, l: !1, exports: {} });
    return e[r].call(o.exports, o, o.exports, n), (o.l = !0), o.exports;
  }
  (n.m = e),
    (n.c = t),
    (n.d = function(e, t, r) {
      n.o(e, t) || Object.defineProperty(e, t, { enumerable: !0, get: r });
    }),
    (n.r = function(e) {
      'undefined' != typeof Symbol &&
        Symbol.toStringTag &&
        Object.defineProperty(e, Symbol.toStringTag, { value: 'Module' }),
        Object.defineProperty(e, '__esModule', { value: !0 });
    }),
    (n.t = function(e, t) {
      if ((1 & t && (e = n(e)), 8 & t)) return e;
      if (4 & t && 'object' == typeof e && e && e.__esModule) return e;
      var r = Object.create(null);
      if (
        (n.r(r),
        Object.defineProperty(r, 'default', { enumerable: !0, value: e }),
        2 & t && 'string' != typeof e)
      )
        for (var o in e)
          n.d(
            r,
            o,
            function(t) {
              return e[t];
            }.bind(null, o)
          );
      return r;
    }),
    (n.n = function(e) {
      var t =
        e && e.__esModule
          ? function() {
              return e.default;
            }
          : function() {
              return e;
            };
      return n.d(t, 'a', t), t;
    }),
    (n.o = function(e, t) {
      return Object.prototype.hasOwnProperty.call(e, t);
    }),
    (n.p = ''),
    n((n.s = 0));
})([
  function(e, t, n) {
    'use strict';
    Object.defineProperty(t, '__esModule', { value: !0 });
    var r = n(1);
    n(2),
      (window.onload = function() {
        r.updateFormAction();
      });
  },
  function(e, t, n) {
    'use strict';
    Object.defineProperty(t, '__esModule', { value: !0 }),
      (t.updateFormAction = function() {
        var e = document.getElementById('330545');
        if (!e) throw new Error('Unable to find element 330545');
        e.setAttribute('action', 'example.com/330542');
      });
  },
  function(e, t, n) {}
]);

这是我的webpack.config.js：

const webpack = require('webpack');
const path = require('path');
const glob = require('glob');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');

module.exports = {
  mode: 'production',
  plugins: [
    new MiniCssExtractPlugin({
      filename: './[name]/customBundle.css',
      chunkFilename: '[id].css',
      ignoreOrder: false
    }),
    new webpack.ProvidePlugin({
        $: "jquery",
        jQuery: "jquery"
    })
  ],
  entry: glob.sync('./forms/**/index.ts').reduce((acc, path) => {
    const entry = path.replace('/index.ts', '');
    acc[entry] = path;
    return acc;
  }, {}),
  module: {
    rules: [
      {
        test: /\.tsx?$/,
        use: [
          {
            loader: 'ts-loader',
            options: {
              transpileOnly: true,
              experimentalWatchApi: true
            }
          }
        ],
        exclude: /node_modules/
      },
      {
        test: /\.s?[ac]ss$/i,
        use: [
          {
            loader: MiniCssExtractPlugin.loader,
            options: {
              hmr: process.env.NODE_ENV === 'development'
            }
          },
          'css-loader',
          'sass-loader'
        ]
      }
    ]
  },
  resolve: {
    extensions: ['.tsx', '.ts', '.js']
  },
  output: {
    filename: './[name]/customBundle.js',
    path: path.resolve(__dirname, './public')
  },
  externals: {
    "jquery": "jQuery"
  }
};

还有我的tsconfig.json：

{
  "compilerOptions": {
    /* Basic Options */
    "target": "es5",                          /* Specify ECMAScript target version: 'ES3' (default), 'ES5', 'ES2015', 'ES2016', 'ES2017', 'ES2018', 'ES2019' or 'ESNEXT'. */
    "module": "commonjs",                     /* Specify module code generation: 'none', 'commonjs', 'amd', 'system', 'umd', 'es2015', or 'ESNext'. */
    "allowJs": true,                          /* Allow javascript files to be compiled. */
    "outDir": "./public",                     /* Redirect output structure to the directory. */
    "removeComments": true,                   /* Do not emit comments to output. */
    "strict": true,                           /* Enable all strict type-checking options. */

    /* Additional Checks */
    "noUnusedLocals": true,                   /* Report errors on unused locals. */
    "noUnusedParameters": true,               /* Report errors on unused parameters. */
    "noImplicitReturns": true,                /* Report error when not all code paths in function return a value. */
    "noFallthroughCasesInSwitch": true,       /* Report errors for fallthrough cases in switch statement. */

    "esModuleInterop": true,                  /* Enables emit interoperability between CommonJS and ES Modules via creation of namespace objects for all imports. Implies 'allowSyntheticDefaultImports'. */
    "newLine": "LF"
  },
  "exclude": [
    "node_modules",
    "form-assembly-templates"
  ]
}
