The tailwindcss-primeui is an official plugin by PrimeTek to provide first class integration between a Prime UI library like PrimeVue and Tailwind CSS. It is designed to work both in styled and unstyled modes. In styled mode, for instance the semantic colors such as primary and surfaces are provided as Tailwind utilities e.g. bg-primary, text-surface-500, text-muted-color.
[Warn] The provided Tailwind configuration in your nuxt.config is non-serializable. Check plugins. Falling back to providing the loaded configuration inlined directly to PostCSS loader. Please consider using tailwind.config or a separate file (specifying in configPath of the module options) to enable it with additional support for IntelliSense and HMR. Suppress this warning with quiet: true in the module options.
