Tailwind CSS v4

Made for Tailwind CSS v4

Version 4 of the eslint-plugin-tailwindcss is:

• re-written from scratch
• using TypeScript
• Based as much as possible on internal assets of Tailwind CSS:
  • via the prettier-plugin-tailwindcss plugin
  • via tailwind-api-utils
• only compatible with:
  • Tailwind CSS v4.x.x
  • ESLint flat config format
  • Node >= 20.19.0

This version has been made possible thanks to the work of hyoban and his project tailwind-api-utils.

The pre-release versions were tested on our Nx monorepo which uses Next.js, react and offcourse Tailwind CSS 4.
