I am trying to get started with Fly.io. I know Vue well and wanted to try Nuxt and Node.js. I cannot seem to figure out how to add server-side components and classes for handling AJAX requests.

I followed the official tutorial https://fly.io/docs/languages-and-frameworks/nuxtjs/

npm init nuxt-app@latest spec-land
