[Vuejs]-Embed a Vueitfy user interface into an existing website

You could take the transpiled, javascript bundle that Webpack creates for your Nuxt/Vuetify application and insert it into whatever webpage would use it. This would let you use the javascript you wrote where you need it on that existing site, but wouldn’t use it for any other pages.

If you don’t like that approach, however, <iframe>s are always an option.
