Deploy a Vue.js App in a subfolder

This is what you need to check when deploy a Vue.js app in a subfolder.

By default a Vue.js build works out of the box if it's in the root of the webserver.

Here the parts you need to check and eventually edit in order to make it works.

vue.config.js

In vue.config.js this is the parameter you may edit based on your situation:

module.exports = {
  publicPath: ''
}

VueRouter

If your app uses VueRouter, check the value of the base config in the router:

const router = new VueRouter({
  mode: 'history',
  base: process.env.BASE_URL,
  routes
})

I'd change it with process.env.VUE_APP_BASE_URL and add .env.production in your root. Then, build it with vue-cli-service build --mode production
