Discard code comment in css

[ngohungphuc]

In my webpack config file. I'm using this config

new OptimizeCSSAssetsPlugin({
                cssProcessorOptions: {
                    safe: true,
                    discardComments: {
                        removeAll: true,
                    },
                },
            })

When run webpack command I'm still see those command in css file. Any idea ?

I have the following and it works:

new OptimizeCssAssetsPlugin({
  cssProcessorPluginOptions: {
      preset: ['default', { discardComments: { removeAll: true } }],
  }
});

The settings are for the default cssnano processor rather than the optimize plugin.

@ngohungphuc I'm having the same problem. Did you find a solution for this? Changin options to

{
      preset: ['default', { discardComments: { removeAll: true } }],
}

didn't work for me

Still working for me. My full plugin config is:

new OptimizeCssAssetsPlugin({
  cssProcessorPluginOptions: {
      assetNameRegExp: /\.css$/g,
      preset: ['default', { discardComments: { removeAll: true } }],
  }
});

Plugin version i'm using is currently 5.0.3

Currently working fine now

Mine works now but only because I put the config into a separate cssnano.config.js file. If I put it in the plugin directly it still doesn't work but I'm cool with having it work in a separate file.
