 `defineI18nRoute()`{lang="ts"} is a compiler macro that you can use to set custom route paths for your **page** components located in the `pages/` directory (unless [set otherwise](https://nuxt.com/docs/api/configuration/nuxt-config#pages-1)). This way you can set custom route paths for each static or dynamic route of your Nuxt application.
