webpack踩过的坑，总结

使用process.argv 获取命令行使用的参数

// 判断是否带production参数，production会压缩js
var isprod = false;
for (var i in process.argv) {
    if (process.argv[i] === "-p" || process.argv[i] === "--production") {
        isprod = true;
        break;
    }
}

url-loader 路径不正确，可通过 publicPath进行配置

output: {
        //context: path.resolve(__dirname, 'scripts'),
        path: path.resolve(HTML_DIST_PATH, "assets"),
        publicPath: '/dist/assets/',//当生成的资源文件和站点不在同一地方时需要配置改地址 e.g.：站点在src,资源生成到/src/static/dist，那么publicPath="/static/dist"
        filename: "[name].[hash:6].js",
        chunkFilename: "[id].chunk.js",
    }

html-webpack-plugin minify: true 报错，请改成

new HtmlWebpackPlugin({
    title: '',
    template: currentpath,
    filename: currentpath.replace("\\html\\", "\\dist\\"),
    minify: {
        "removeAttributeQuotes": true,
        "removeComments": true,
        "removeEmptyAttributes": true,
    }
    //chunks: ['index', 'vendors'],   // 配置该html文件要添加的模块
    inject: 'body'
})

//extract-text-webpack-plugin 同时使用style-loader和postcss-loader时会报错，将style-loader移除
ExtractTextPlugin.extract(["css-loader", "postcss-loader"])
