Duplicate code in output

[kibin]

Say I have multiple components that require the same css file. When I use this plugin I get output file with multiple duplications of the contents of this file. Is there a way to prevent extracting files that were already extracted in the output file?

I'm experiencing this issue too.
Tried with DedupePlugin and UglifyJsPlugin, without success.

It seems that this is something that has to be handled by the specific loader.

See, for example:
webpack-contrib/sass-loader#31

I'm facing this problem with cssnext-loader.

@Zimok yeah, you’re right, the issue is happening before extract text plugin starts working

While the original issue here is related to sass/less/stylus, a fix/hack/patch for this is to use the optimize-css-assets-webpack-plugin in conjunction with extract-text-webpack-plugin to produce, like this: https://gist.github.com/phun-ky/766e5ec9f75eac61c945273a951f0c0b.

If you want to use this in dev, you will have to use a plugin like write-file-webpack-plugin to force webpack to write the file to disk in dev.
