useRoute inside plugin

Don't call useRoute inside a Nuxt plugin setup—it's only available in component
contexts. Instead, read the route name from the router instance on the Nuxt app.
This ensures the plugin works both on server and client side.

export default defineNuxtPlugin({
  name: 'plugin',
  parallel: true,
  setup: async () => {
    const route = useRoute();
    if (route.name === 'my-route') {
      doSomething()
    }
  },
});
