Question

我已经按照一些指南设置了CommonsChunkPlugin，但它似乎并没有起作用。我也在这里搜索并阅读了其他帖子，但没有运气。

我有三个文件（TypeScript），它们导入了一些相同的库（fancybox，moment和pikaday）。它们是使用ES模块语法导入的：

import * as fancybox from 'fancybox';
import * as moment from 'moment';
import * as pikaday from 'pikaday';

我的tsconfig.json设置为输出ES6语法和模块：

{
    "compileOnSave": true,
    "compilerOptions": {
        "target": "es6",
        "module": "es6",
        "noEmitOnError": true,
        "moduleResolution": "node",
        "sourceMap": true,
        "diagnostics": false,
        "noFallthroughCasesInSwitch": true,
        "noImplicitReturns": true,
        "traceResolution": false
    },
    "exclude": [
        "node_modules",
        "venue-finder"
    ]
}

我的webpack.config.js：

const webpack = require('webpack');
const path = require('path');
const WebpackNotifierPlugin = require('webpack-notifier');
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;

module.exports = [{
    bail: true,
    entry: {
        global: path.resolve(__dirname, 'js/responsive/global.ts'),
        todo: path.resolve(__dirname, 'js/todo/todo.ts'),
        budget: path.resolve(__dirname, 'Planner/javascript/Budget/BudgetPlannerUI.ts'),
        promotions: path.resolve(__dirname, 'js/promotions-management.ts'),
        planner: path.resolve(__dirname, 'Planner/javascript/MyPlanner.ts')
    },
    output: {
        path: path.resolve(__dirname, 'dist/js'),
        filename: '[name].js'
    },
    module: {
        rules: [{
            test: /\.ts(x?)$/,
            exclude: /node_modules/,
            use: [
                {
                    loader: 'babel-loader',
                    options: {
                        'presets': [
                            ['env', {
                                'modules': false
                            }]
                        ]
                    }
                },
                {
                    loader: 'ts-loader'
                }
            ]
        }]
    },
    plugins: [
        new WebpackNotifierPlugin({ alwaysNotify: true }),
        new webpack.IgnorePlugin(/^\.\/locale$/, /moment$/),
        new webpack.optimize.CommonsChunkPlugin({
            name: 'commons',
            filename: 'commons-bundle.js',
            minchunks: 2
        }),
        new BundleAnalyzerPlugin()
    ],
    resolve: {
        extensions: ['.js', '.ts', '.tsx']
    },
    devtool: 'none'
}];

据我所知，应该找到任何使用了两次或更多（有三次）的块并将其移入commons-bundle.js但是当我运行webpack并查看输出文件我可以看到pikaday，moment和fancybox都被包含在每个文件中而不是被移动到commons-bundle.js

非常感谢任何帮助。

您可能希望将minChunks选项作为函数而不是整数值。你fancybox，moment和pickaday来自node_modules，因此像下面这样修改minChunks应该有效 -

new webpack.optimize.CommonsChunkPlugin({
            name: 'commons',
            filename: 'commons-bundle.js',
            chunks: [global, todo, budget, promotions, planner], //optional, however I find this as good practice
            minChunks: function (module) {
               return module.context && module.context.indexOf("node_modules") !== -1;
            }
        }),

Webpack＆amp; TypeScript CommonsChunkPlugin无效
