Duplicated packages webpack, css-loader, style-loader

[yp]

If I install craco-less (either with yarn or npm, then a duplicated version of webpack, css-loader, and style-loader is installed, since the craco-less depends on them but with a different version range than react-scripts.
(I am aware that this is somehow related to #3.)
While apparently it did not cause any bug, I wonder if this could not be a source of obscure bugs in the future.
Are those dependencies only needed to "silence" the warnings reported on StackOverflow? If this is the case, can you consider to drop them?

Yes, these dependencies are just to silence the npm/yarn warnings.

I think I didn't realize that css-loader and style-loader were already dependencies of react-scripts, so it makes sense to remove those. After that, the only warning is:

warning " > less-loader@4.1.0" has unmet peer dependency "webpack@^2.0.0 || ^3.0.0 || ^4.0.0".

I've left a comment on a yarn issue. For now I'm just going to leave the webpack dependency, and it shouldn't cause any issues.

Hi again, thanks for opening this issue! I've decided to remove css-loader and style-loader from the dependencies. I've kept the webpack dependency, but I've pinned this to the same version as react-scripts, and I've added a script to automate this. So whenever react-scripts changes their webpack version, I'll just run this script to use the same webpack version, and release a new version of craco-less.

I really hate warnings and this seemed to be the only way to fix it, so I think it's a good workaround for now.

Thanks for the quick fix (even if it was not causing any real problem).
Do you mind to consider to move craco as a peerDependency? Since it is a plugin for it, I think that it should specified as such (see, for example, the yarn recommendations).

[ndbroadbent]

Oh right, yes that's a good idea! I think react-scripts should also be a peerDependency, because that will already be in the app's package.json.

The only problem is that this breaks the tests, because peer dependencies are not installed when you run yarn install in the craco-less repo. So I guess I also need to add them as devDependencies. A bit weird to include them in two places, but I think that's the right way to do it for now. It doesn't look like it's possible to install peerDependencies locally, and I found this issue in the yarn repo.

I also had to do that for the craco-antd package, which depends on craco-less. (Adding @craco/craco and react-scripts to both devDependencies and peerDependencies.)

So this seems to work pretty well and doesn't show any warnings. Thanks!
