Question

我遇到了一个问题。创建了webpack中定义的所有入口js文件，对于分块的供应商文件也是如此。在webpack中，我将优化部分定义为：

optimization: {
   splitChunks: {
       chunks: "all"
    }
}

在我的dist文件夹中，一切看起来都很好：内容文件在那里，生成了js和分块的供应商文件，但是当我访问站点js文件时，已正确获取了文件，但接下来我的内容都没有，也没有分块的供应商。

Invalid result - blank screen

这是我使用的Webpack配置。没有优化部分，所有内容（img，字体）和js文件都会成功提供。

module.exports = {
  entry: {
    tppauth: "./src/pages/tppauth.js",
    notfound: "./src/pages/notfound.js",
    servererror: "./src/pages/servererror.js",
  },
  output: {
    filename: "[name].js",
    path: path.resolve(__dirname, "dist"),
    publicPath: "/dist/",
  },
  devServer: {
    contentBase: "/dist/"
  },
  module: {
    rules: [
      {
        test: /\.(js|jsx)$/,
        exclude: /node_modules/,
        use: { loader: "babel-loader" }
      },
      {
        test: /\.(woff|woff2|eot|ttf|png|gif|svg)?$/,
        use: { loader: "file-loader" }
      },
      {
        test: /\.(less|css)$/,
        use: ["style-loader","css-loader","less-loader"]
      }
    ]
  },
  resolve: {
    extensions: [".js", ".jsx"],
    alias: {
      ['~']: __dirname
    }
  },
  optimization: {
    splitChunks : {
      chunks: 'all'
    }
  },
};

我的js文件，该文件呈现了一些其他已定义的组件

import React from "react";
import ReactDOM from "react-dom";
import PropTypes from "prop-types";
import dateFormat from "dateformat";

import "~/Content/Styles/container.less";

class PaymentAuthorization extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      ...this.state,
      request: {}
    };
  }
  render() {
    return (
      <IntlProvider locale="fr" messages={messages["fr"]}>
        <ErrorBoundary>
          <div className="center">{ComponentToRender}</div>
        </ErrorBoundary>
      </IntlProvider>
    );
  }
}
ReactDOM.render(<PaymentAuthorization/>, document.getElementById("app"));

当我尝试对文件进行分块时，我是否缺少js文件中的其他导入？ Valid response - without otpimization section

尝试删除splitChunks选项以查看其是否有效。

您可以按以下方式查看我的配置

const path = require("path");
const webpack = require("webpack");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const CompressionPlugin = require("compression-webpack-plugin");
const UglifyJsPlugin = require("uglifyjs-webpack-plugin");
const WebpackShellPlugin = require('webpack-shell-plugin');
const OptimizeCSSAssetsPlugin = require("optimize-css-assets-webpack-plugin");

Answer 2

好几次休息后，我发现自己做错了。我没有为新的捆绑文件添加<script src='...' />标签。

我使用html-webpack-plugin来获取我的html模板并将所需的javascript文件放入其中，但是它也可以手动完成。这是我的新cshtml文件，其中的node_modules分为两个单独的文件：

@{
    Layout = "~/Views/Shared/LayoutPage.cshtml";
}<script type="text/javascript" src="/dist/vendor2.js"></script><script type="text/javascript" src="/dist/vendor1.js"></script><script type="text/javascript" src="/dist/tppauth.js"></script>

主js文件未导入创建的分块文件
