标签: reactjs webpack compression gzip

我想将我的react应用压缩为gzip,实际上是2.2 mb,所以我使用了 compression-webpack-plugin ,但是我无法压缩
我的 webpack.config.js

const webpack = require('webpack');
const path = require('path');
const fs = require("fs")
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;
const CompressionPlugin = require('compression-webpack-plugin');

const VENDOR_LIBS =[
    'antd','axios','moment','rc-time-picker','react',
    'react-dom','react-ga','react-google-maps','react-loadable',
    'react-redux','react-router','react-router-dom','recompose','redux','redux-thunk'
]
module.exports = (env) => {
    const isProduction = env === 'production';
    const CSSExtract = new ExtractTextPlugin('styles.css');

    return {
        node: {
            fs: 'empty',
            child_process: 'empty',
          },
        entry: {
            bundle:'./src/app.js',
            vendor:VENDOR_LIBS
        },
        output: {
            path: path.join(__dirname, 'public'),
            filename: '[name].js'
        },
        module: {
            rules: [{
                loader: 'babel-loader',
                test: /\.js$/,
                exclude: /node_modules/
            }, {
                test: /\.s?css$/,
                use: CSSExtract.extract({
                    use: [
                        {
                            loader: 'css-loader',
                            options: {
                                sourceMap: true
                            }
                        },
                        {
                            loader: 'sass-loader',
                            options: {
                                sourceMap: true
                            }
                        }
                    ]
                })
            },{
                test: /\.(gif|svg|jpg|png|ttf|eot|woff(2)?)(\?[a-z0-9=&.]+)?$/,
                loader: "file-loader",
            }],
        },

        plugins: [
            CSSExtract,
            new webpack.optimize.CommonsChunkPlugin({
                name:'vendor'
            }),
            new HtmlWebpackPlugin({
                template:'src/index.html'
            }),
            new CompressionPlugin(),
            new BundleAnalyzerPlugin()

        ],
        devtool: isProduction ? 'source-map' : 'inline-source-map',
        devServer: {
            contentBase: path.join(__dirname, 'public'),
            historyApiFallback: true,
            host:'0.0.0.0',
            disableHostCheck: true,
        }
    };
};

显示我错误

  

TypeError:无法读取未定义的属性'emit'
  在CompressionPlugin.apply(/ media / .........
  如果我向

之类的 CompressionPlugin 添加其他选项,
new CompressionPlugin({
  asset: '[path].gz[query]',
  algorithm: 'gzip',
  test: /\.js$|\.css$|\.html$|\.eot?.+$|\.ttf?.+$|\.woff?.+$|\.svg?.+$/,
  threshold: 10240,
  minRatio: 0.8
  })

显示我错误

  

抛出新的ValidationError(ajv.errors,name);
  ValidationError:压缩插件无效选项
  选项不应具有其他属性

我该如何解决这个问题,或者有其他方法可以gzip我的应用程序。

将“资产”更改为“文件名”。

new CompressionPlugin({
  filename: '[path].gz[query]',
  algorithm: 'gzip',
  test: /\.js$|\.css$|\.html$|\.eot?.+$|\.ttf?.+$|\.woff?.+$|\.svg?.+$/,
  threshold: 10240,
  minRatio: 0.8
})

compression-webpack-plugin@2.0发生了重大变化。

您要么必须升级到webpack 4,要么使用compression-webpack-plugin@1.1.12。

不建议使用资产选项,请改用filename

答案 2 :(得分:0)

您的问题是您需要与webpack 4一起运行,并且节点必须大于6.9.9.0,如文档所述:

  

“此模块至少需要Node v6.9.0和Webpack v4.0.0。”

您的配置也有误:

new CompressionPlugin({
  filename: '[path].gz[query]',
  algorithm: 'gzip',
  test: /\.js$|\.css$|\.html$|\.eot?.+$|\.ttf?.+$|\.woff?.+$|\.svg?.+$/,
  threshold: 10240,
  minRatio: 0.8
})
