Question

当我使用webpack 4拆分js文件时，然后我得到dist目录，其中包含：app.js，vendor.js和另外一个js文件名vendor〜app.js，它怎么来以及为什么出现？

以下是这些文件：

这是我的webpack配置：

CREATE MATERIALIZED VIEW MV_DATA
BUILD IMMEDEATE 
REFRESH FAST START WITH (SYSDATE) NEXT (TRUNC(SYSDATE) + 1) + 6 / 24 WITH ROWID
ON COMMIT
DISABLE QUERY REWRITE
AS SELECT * FROM YOURTABLE

在我的entry.js中：

const path = require('path');

const CleanWebpackPlugin = require('clean-webpack-plugin');

module.exports = {

    mode: 'production',

    entry: {
        vendor: ['react', 'react-dom', 'redux', 'react-redux', 'react-router-dom'],
        app: './src/entry.js'
    },

    output: {
        path: path.resolve(__dirname, 'dist'),
        chunkFilename: '[name].js',
        publicPath: '/',
        filename: '[name].js'
    },

    module: {
        rules: [
            {
                test: /\.js[x]?$/,
                exclude: /node_modules/,
                include: path.resolve(__dirname, 'src'),
                use: [{
                    loader: 'babel-loader',
                    options: {
                        cacheDirectory: true,
                        babelrc: false,
                        presets: [['@babel/preset-env', {
                            "modules": false
                        }], '@babel/preset-react'],
                        plugins: ['@babel/plugin-transform-runtime', "@babel/plugin-proposal-class-properties"]
                    }
                }]
            },
        ]
    },

    optimization: {
        runtimeChunk: {
            name: 'manifest'
        },
        splitChunks: {
            minChunks: 1,
            minSize: 2,
            chunks: 'all',
            name: true,
            cacheGroups: {
                common: {
                    test: 'vendor',
                    chunks: 'initial',
                    name: 'vendor',
                    enforce: true,
                }
            }
        }
    },
    plugins: [
        new CleanWebpackPlugin(['dist']),
    ]
}

从入口点删除供应商。即使在语义上也是错误的。

这些文件名旨在防止代码重复。如果您有真正的第二个入口点：anotheApp.js，您将有两个选择加载到页面上：

vendors〜anotheApp〜app.bundle.js + app.bundle.js
vendors〜anotheApp〜app.bundle.js + anotherApp.bundle.js。

将每个包装放到自己的口袋中

  this.platform.ready().then((readySource) => {
  let filter = {
    box: 'inbox', // 'inbox' (default), 'sent', 'draft', '' for all
    indexFrom: 0, // start from index 0
    maxCount: 3, // count of SMS to return each time
  };

  if (SMS) SMS.listSMS(filter, (ListSms) => {
  let messages = ListSms;
  console.log(messages);
    ,
    Error => {
      alert(JSON.stringify(Error))
    });
});

webpack拆分js文件，再获取一个文件
