@tailwindcssinjs/tailwindcss-data

The tailwind-data package uses Tailwind internals to extracts/generate all the data you could want from Tailwind. It provides the data in a structured way with the necessary utilities to create and manipulate this data.

In short: Unofficial Tailwind developer API

More info coming soon!

This package is under development breaking changes possible!
