The @unocss/eslint-plugin package provides ESLint rules and a recommended configuration for enforcing UnoCSS style conventions within your JavaScript and TypeScript projects. It helps maintain consistent styling by flagging utility classes that are missing, incorrectly ordered, or potentially unused, promoting a cleaner and more maintainable codebase. The plugin integrates seamlessly with your existing ESLint setup, giving immediate feedback on styling violations during development, ensuring you leverage UnoCSS effectively.
