Webpack + UglifyJs : how to ignore warnings about 3rd party library code

Question

使用Webpack，我从UglifyJSPlugin收到了所有第三方代码的警告。

是否可以仅对某些库关闭警告？

Answer 1

不，根据UglifyJS压缩程序选项，目前仅能关闭所有警告:https://github.com/mishoo/UglifyJS2#compressor-options

您可以通过将UglifyJS选项传递给Webpack的UglifyJsPlugin的构造函数来关闭所有警告:https://webpack.github.io/docs/list-of-plugins.html#uglifyjsplugin

在您的webpack.config.js中，您需要输入以下内容:

var webpack = require('webpack');

module.exports = {
    ...
    plugins: [
        new webpack.optimize.UglifyJsPlugin({
            compress: {
                warnings: false
            }
        })
    ]
}
