eslint-plugin-tailwind-canonical-classes

ESLint plugin that enforces canonical Tailwind CSS class names using Tailwind CSS v4's official canonicalization API. Version 1.3.3, actively maintained with regular releases. Key differentiators: integrates directly with Tailwind v4's `canonicalizeCandidates` for accurate class ordering and aliasing, supports auto-fix, works with utility functions like `cn()`, `clsx()`, and `twMerge()`, provides zero-config recommended setups for both flat and legacy ESLint configs. Alternative to manual class sorting plugins, but requires Tailwind v4 and Node 18+.
