webpack convert css unit with uglifyjs plugin -

it's weird, actually, think quite easy come across, have found nothing issue~

i have tested / without uglifyjs plugin, , i'm quite sure plugin results in issue.

in style files, px / em have been used, after compression, of px has been converted pc / pt, totally have no clue~

even though uglifyjs has js in name affects other loaders. answer hidden in uglifyjsplugin docs.

minimize javascript output of chunks. loaders switched minimizing mode. (...)

the discussion takes place here:

https://github.com/webpack/webpack/issues/283

no workaround yet see.

i long doesn't mess build, keep using uglifyjs. when starts, can try

1. switching babili (babel based minifier) + babili-webpack-plugin.

   https://babeljs.io/blog/2016/08/30/babili

   https://www.npmjs.com/package/babili-webpack-plugin

   and minifying css css-loader minimize option.

from https://github.com/webpack/css-loader :

you can disable or enforce minification minimize query

parameter.  require("css-loader?minimize!./file.css") (enforced) require("css-loader?-minimize!./file.css") (disabled) 

or

2. disabling minimize option in css-loader plugin (overwriting uglifyjs behavior). don't worry csses will minimized, bit less (in case). - better crashing production build.

i tried babili without success second option helped in production build of project.
