core-js dependency

[bpierre]

Hi, thanks for rollpkg, I started to use it on a few projects and it feels great!

I just wanted to open this issue to track one I was having with the csso-webpack-plugin dependency (via package-build-stats): zoobestik/csso-webpack-plugin#28

The temporary fix is to have core-js as a devDependency in my library. Until csso-webpack-plugin and package-build-stats receive publish a new version, maybe core-js could be added as dependency in rollpkg?

I'm not sure I understand the what the issue is? Is it possible to reproduce? Thanks.

Sorry, this is the error I was getting on build:

I added core-js as dependency as a temporary fix. Please install rollpkg v0.5.4. I'm going to leave this issue open as a reminder to remove core-js when this is fixed upstream.

[bpierre]

Oh that’s great, thank you!

[rafgraph]

Yeah I hadn't seen the error before and wasn't able to reproduce it until I regenerated rollpkg-example-package's lock file. But seeing as it would affect every fresh install of rollpkg, a fix was required.

[bpierre]

Interestingly, I noticed this issue by migrating a new project to rollpkg, while use-nft was working well. Then at some point, I started to have the issue on use-nft as well − probably after I deleted the lockfile.

So I suspect core-js was the dependency of another module before (maybe not even related to rollpkg, it could be eslint, prettier or something else every project uses), and a minor upgrade in that module removed it, breaking the implicit dependency in csso-webpack-plugin.

Fixed in csso-webpack-plugin@2.0.0-beta.3
