ESLint plugin to automatically break up long tailwind class strings into multiple lines based on a specified print width or class count. This improves readability and eliminates horizontal scrolling.
In addition it sorts the classes logically, removes unnecessary whitespaces and duplicate classes and groups the classes by their variants. It works in jsx, svelte, vue, and html files.
[!NOTE] Support for tailwindcss v4 is currently in beta.
If you are on tailwindcss v4, install the beta version of this plugin:
npm i -D eslint-plugin-readable-tailwind@beta. Please report any feedback or issues you encounter with the beta version in the discussions. Additional breaking changes are documented in the CHANGELOG on the v2 branch.
