Please guys,
If you guys want to support me, I don't like the idea of financial donations while I'm still a healthy young man, just hire me or tell someone to hire me.

I think the v4 branch is https://github.com/francoismassart/eslint-plugin-tailwindcss/tree/alpha/v4-basic-files

Can you show how to use it inside the eslint flat config?

[drake-nathan]

Amazing work. Any chance this will be merged soon? Anything I can help with?

[drake-nathan]

eslint should be a peer dep, right?

[sunwukonga]

Concur. Both @typescript-eslint/utils and eslint are used to import types. They can both be moved to devDependencies.

Thanks for this great work! Any news about this PR?

[brandanking-decently]

@ImBIOS do you know if this will get merged soon? If not do you think you could create your own NPM package for people to use in the mean time?
