Docs refer to deprecated webpack.optimize.UglifyJsPlugin

[1j01]

https://webpack.js.org/configuration/plugins/#plugins

I don't know if there's other stuff that needs to be updated here, or if maybe the documentation's been updated but it's just not published...

It is deprecated?

[1j01]

The UglifyJsPlugin itself isn't, but accessing webpack.optimize.UglifyJsPlugin is, because you're supposed to add it as a dependency and pass it to optimization.minimizer

[montogeek]

Uhmm, using it as a plugin triggers a warning or something?
I think it works just fine as a plugin.

[1j01]

webpack.optimize.UglifyJsPlugin gives an error message: "webpack.optimize.UglifyJsPlugin has been removed, please use config.optimization.minimize instead."

webpack.optimize.UglifyJsPlugin isn't exposed anymore, one has to explicitly import it since webpack >= v4.0.0

- const UglifyJsPlugin = webpack.optimize.UglifyJsPlugin
+ const UglifyJsPlugin = require('uglifyjs-webpack-plugin')

It ships with webpack by default and options can be passed to the 'build-in' plugin via config.optimization.minimize removing the need to import it at all in most cases

[montogeek]

Please send a PR to this page (https://webpack.js.org/configuration/plugins/#plugins) updating it with your findings.

You just need to remove it from the plugins https://webpack.js.org/configuration/plugins/#plugins page
It is documented here btw: https://webpack.js.org/configuration/optimization/

Also presumably the CommonsChunkPlugin usage should be updated to show requireing it, and likely other stuff is outdated. I don't want to work on this; I've never used the plugins option, and so I hope someone with at least that qualification can pick this up.

[EugeneHlushko]

@1j01 ok, in that case im picking it up
