Here’s a guide on setting up a simple test app with Nuxt 3 and PrimeVue:

Step 1: Create a New Nuxt 3 Project

Start by creating a new Nuxt 3 project using the following commands:

npx nuxi init nuxt3-primevue-app
cd nuxt3-primevue-app
npm install

Step 2: Install PrimeVue

Install PrimeVue and its required dependencies:

npm install primevue@^3.11.0 primeicons

Step 3: Set Up PrimeVue in Nuxt

To use PrimeVue in your app, you need to configure it in nuxt.config.ts:

1. Open nuxt.config.ts and add PrimeVue and PrimeIcons to the CSS and build settings.

   export default defineNuxtConfig({
     css: [
       'primevue/resources/themes/saga-blue/theme.css',
       'primevue/resources/primevue.min.css',
       'primeicons/primeicons.css'
     ],
     build: {
       transpile: ['primevue']
     }
   });
   

Step 4: Register PrimeVue Globally

You can create a PrimeVue plugin to register components globally:

1. Create a file named primevue.ts in the plugins directory (plugins/primevue.ts).
2. Add the following code to initialize PrimeVue:

   import PrimeVue from 'primevue/config';
   import Button from 'primevue/button';
   
   export default defineNuxtPlugin((nuxtApp) => {
     nuxtApp.vueApp.use(PrimeVue);
     nuxtApp.vueApp.component('Button', Button);
   });
   

Step 5: Use PrimeVue Components in Your Pages

You can now use PrimeVue components in your Nuxt app. For example, create a simple button in the pages/index.vue file:

1. Edit pages/index.vue:

   <template>
     <div class="p-4">
       <h1>Welcome to Nuxt 3 with PrimeVue</h1>
       <Button label="Click Me" />
     </div>
   </template>
   

Step 6: Run Your App

Run the app in development mode to test your setup:

npm run dev

That’s it! You now have a Nuxt 3 app running with PrimeVue components ready for use. You can experiment with different PrimeVue components to build a more complex app.
