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.
If not completed already, begin with setting up Tailwind in your project. Visit the documentation for the necessary steps. Once the Tailwind is installed properly, install the primeui plugin.
In the CSS file that contains the tailwindcss import, add the tailwindcss-primeui import as well.
After installation, configure the plugin at your tailwind configuration file.
