Question

我有点卡住了

我有一个脚本，可以在加载时以编程方式将清单，供应商和应用程序注入页面。我需要在构建过程中将此脚本注入到html中，但在开发过程中不需要这样做。

这是我的prod配置（默认情况下，有一些非常小的变化） -

'use strict'
const path = require('path')
const utils = require('./utils')
const webpack = require('webpack')
const config = require('../config')
const merge = require('webpack-merge')
const baseWebpackConfig = require('./webpack.base.conf')
const CopyWebpackPlugin = require('copy-webpack-plugin')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const ExtractTextPlugin = require('extract-text-webpack-plugin')
const OptimizeCSSPlugin = require('optimize-css-assets-webpack-plugin')
const UglifyJsPlugin = require('uglifyjs-webpack-plugin')

const env = process.env.NODE_ENV === 'testing'
  ? require('../config/test.env')
  : require('../config/prod.env')

const webpackConfig = merge(baseWebpackConfig, {
  module: {
    rules: utils.styleLoaders({
      sourceMap: config.build.productionSourceMap,
      extract: true,
      usePostCSS: true
    })
  },
  devtool: config.build.productionSourceMap ? config.build.devtool : false,
  output: {
    path: config.build.assetsRoot,
    filename: utils.assetsPath('js/[name].js'),
    chunkFilename: utils.assetsPath('js/[id].js')
  },
  plugins: [
    // http://vuejs.github.io/vue-loader/en/workflow/production.html
    new webpack.DefinePlugin({
      'process.env': env
    }),
    new UglifyJsPlugin({
      uglifyOptions: {
        compress: {
          warnings: false
        }
      },
      sourceMap: config.build.productionSourceMap,
      parallel: true
    }),
    // extract css into its own file
    new ExtractTextPlugin({
      filename: utils.assetsPath('css/[name].css'),
      // set the following option to `true` if you want to extract CSS from
      // codesplit chunks into this main css file as well.
      // This will result in *all* of your app's CSS being loaded upfront.
      allChunks: false,
    }),
    // Compress extracted CSS. We are using this plugin so that possible
    // duplicated CSS from different components can be deduped.
    new OptimizeCSSPlugin({
      cssProcessorOptions: config.build.productionSourceMap
        ? { safe: true, map: { inline: false } }
        : { safe: true }
    }),

    // copy custom static assets
    new CopyWebpackPlugin([
      {
        from: path.resolve(__dirname, '../static'),
        to: config.build.assetsSubDirectory,
        ignore: ['.*']
      }
    ]),

    // generate dist index.html with correct asset hash for caching.
    // you can customize output by editing /index.html
    // see https://github.com/ampedandwired/html-webpack-plugin
    new HtmlWebpackPlugin({
      filename: process.env.NODE_ENV === 'testing'
        ? 'index.html'
        : config.build.index,
      template: 'index.html',
      inject: false,
      minify: {
        removeComments: true,
        collapseWhitespace: true,
        removeAttributeQuotes: true
        // more options:
        // https://github.com/kangax/html-minifier#options-quick-reference
      },
    }),
    new AddAssetHtmlPlugin({
      filepath: require.resolve('../static/js/init.js'),
      publicPath: '/static/js/init.js',
      includeSourcemap: false
    }),
    // keep module.id stable when vender modules does not change
    new webpack.HashedModuleIdsPlugin(),
    // enable scope hoisting
    new webpack.optimize.ModuleConcatenationPlugin(),
    // split vendor js into its own file
    new webpack.optimize.CommonsChunkPlugin({
      name: 'vendor',
      minChunks (module) {
        // any required modules inside node_modules are extracted to vendor
        return (
          module.resource &&
          /\.js$/.test(module.resource) &&
          module.resource.indexOf(
            path.join(__dirname, '../node_modules')
          ) === 0
        )
      }
    }),
    // extract webpack runtime and module manifest to its own file in order to
    // prevent vendor hash from being updated whenever app bundle is updated
    new webpack.optimize.CommonsChunkPlugin({
      name: 'manifest',
      minChunks: Infinity
    }),
    // This instance extracts shared chunks from code splitted chunks and bundles them
    // in a separate chunk, similar to the vendor chunk
    // see: https://webpack.js.org/plugins/commons-chunk-plugin/#extra-async-commons-chunk
    new webpack.optimize.CommonsChunkPlugin({
      name: 'app',
      async: 'vendor-async',
      children: true,
      minChunks: 3
    })
  ]
})

if (config.build.productionGzip) {
  const CompressionWebpackPlugin = require('compression-webpack-plugin')

  webpackConfig.plugins.push(
    new CompressionWebpackPlugin({
      asset: '[path].gz[query]',
      algorithm: 'gzip',
      test: new RegExp(
        '\\.(' +
        config.build.productionGzipExtensions.join('|') +
        ')$'
      ),
      threshold: 10240,
      minRatio: 0.8
    })
  )
}

if (config.build.bundleAnalyzerReport) {
  const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin
  webpackConfig.plugins.push(new BundleAnalyzerPlugin())
}

module.exports = webpackConfig

我需要在html中添加static/js/init.js，但如果文件是静态的，并且不是块，我不知道该怎么做。有什么建议吗？谢谢！

我尝试使用add-asset-html-webpack-plugin但无法正常工作

Answer 1

您可以在使用html-webpack-plugin和copy-webpack-plugin生成的static/js/init.js文件中插入index.html。这还需要一个支持添加脚本资源的html模板，例如html-webpack-template中提供的资源。

以下是这些插件的必要配置：

plugins: [
    new HtmlWebpackPlugin({
        template: 'path-to/node_modules/html-webpack-template/index.ejs',
        inject: false,
        scripts: ['/static/js/init.js']
    }),
    new CopyWebpackPlugin([
        {
            from: './path/to/static/js/init.js',
            to: path.join(config.build.assetsRoot, 'static/js/init.js')
        }
    ])
]

此处CopyWebpackPlugin用于将静态资产（本例中为脚本）复制到输出构建文件夹。然后，输出路径将添加到scripts的{{1}}选项中，以便添加引用该静态资产的HtmlWebpackPlugin标记。

您可以使用此配置和其他有用的配置检查工作Webpack Demo。

Answer 2

如果我找到了您并且您不想在构建过程中处理该文件，则可以将静态js添加到index.html。

像这样：

<script src="static/js/init.js"></script>

Answer 3

我最终解决了这个问题。

我的inject: false中最初有HtmlWebpackPlugin，这阻止html-webpack-include-assets-plugin工作。

为了让它正常工作，我使用html-webpack-include-assets-plugin来注入任何静态资源，然后在我的new HtmlWebpackPlugin中将chunks设置为空数组（[]）。这意味着我的块仍然被编译但没有被转储到最终的构建HTML中。

在构建期间将静态文件添加到HTML（Webpack）
