Link to a file using href on Vue.js

I am trying to link to an external Vue file from my Vuejs app (I'm trying to have a live demo of some projects I made in Vue and they're stored locally in the same server)

HTML:

<a :href="publicPath + 'dis/index.html'">Live demo</a>

JS/Vue:

data(){
  return {
    publicPath: process.env.BASE_URL,
}},

I can't seem to find any way to do this, thanks in advance
