Use CDN as NuxtJs package

Hello, I am starting in Nuxtjs. I am trying to use recent technologies to a project.

For now I do not want to have packages like Vue, Viutify among others on the server, since it would be an additional load on the data transfer from the server.

I have decided to use the Vue cdn, VueRouter, Vuetify and others but I cannot include them as external packages from a cdn in NuxtJs and use them as for example ‘imports Vue from Vue’.

I have already tried to put in 'modules' a "publicPath" and in' plugins: ‘src '' but it generates an error since it is not a link.

For example this is the way for external packages but on the same server https://nuxtjs.org/guide/plugins#external-packages.

Someone could guide me how to achieve since I want to use the minimum bandwidth of the server.

Thank you
