I disabled the jest-setup.js errors. There are only 2 left in /src/utils/__tests__/parseFunctionArguments.js

Yeah I can fix the current warnings/errors.

[XhmikosR]

@kristerkari maybe we should not silence the jest/no-standalone-expect errors in jest-setup.js?

Feel free to fix those too. And also, if you want me to cherry pick any of these patches in master let me know. I can rebase this branch before the final merge.

[XhmikosR]

Oh, and also, it would be nice if we could find a way to fix these warnings too :)

You did not set any plugins, parser, or stringifier. Right now, PostCSS does nothing. Pick plugins for your case on https://www.postcss.parts/ and use them in postcss.config.js.

I originally took the code from stylelint's repo and did not want to change it, so that's why it's there. I haven't checked if their test runner code has changed since then.

Those tests were missing the parser setting for PostCSS. Fixed now.

[XhmikosR]

I think we could cherry pick a couple of patches like the postcss warnings fix and the missing it block patches. Do you want me to do sherry pick those to master? If so, I'll rebase this branch after that.

Please do :)

[XhmikosR]

Done and branches rebased. Just make sure you don't override them.

If you want to release a new patch from master, now it's a good time. Just make sure you do npm i after you switch to master, and then your usual steps.

[kristerkari]

Alright, I'll publish a patch with the changes in master.

[XhmikosR]

Added back the node/no-unsupported-features rules with the version set to 10.0.0.

I think we can merge this in the v4-dev branch if you agree.

[XhmikosR]

One last thing @kristerkari: this is the latest 10.x version. The same goes for the package.json engines version. I guess it's OK since we have the ESLint rules in place, but it's your call.

[kristerkari]

That is ok. We shouldn't need to care about minor versions.
