Question

我想使用Webpack UglifyJSPlugin仅从我的包中删除注释。我目前有以下UglifyJSPlugin配置：

webpackPlugins = [
    new DedupePlugin(),
    new UglifyJsPlugin({
        compress: false,
        minimize: false,
        outputs: {
            comments: false
        }
    })
]

然而，这仍然似乎缩小了整个捆绑。还有其他选项可以删除我没有利用的评论吗？有没有办法用UglifyJSPlugin正确地做到这一点？

Answer 1

这就是你需要的：

new UglifyJsPlugin({
    comments: false,
}),

Answer 2

你正在寻找的东西可能是美化＆＃34;结合＆＃34; mangle＆＃34;。

＆＃34;美化＆＃34;将输出缩进代码而不是单行文件，因此您希望它为Exception in thread "JavaFX Application Thread" java.lang.RuntimeException: java.lang.reflect.InvocationTargetException at

false

Answer 3

使用webpack 2，以下设置对我有用。

new webpack.optimize.UglifyJsPlugin({
  output: {
    comments: false,
    beautify: true,
  },
  mangle: false,
  compress: false,
}),

Answer 4

Webpack 5 现在有一个稍微不同的配置文件：

const UglifyJsPlugin = require('uglifyjs-webpack-plugin');

module.exports = {
    optimization: {
        minimizer: [
            new UglifyJsPlugin({
                uglifyOptions: {
                    output: {
                        comments: false,
                        beautify: true,
                    },
                    mangle: false,
                    compress: false
                },
            }),
        ],
    },
    ...
}
