How base option works in vue-router

Question

As par documentation of base option:

The base URL of the app. For example, if the entire single page application is served under /app/, then base shou

Answer 1

The base has a default value of '/'. Drawing analogy from how it is used to route:

Home

or

I just omitted the /app and it works. The base doesn't need to be part of the router-link

EDIT

Use of base in vue-router

(For this test I had used vue-cli with the webpack template.)

I had my router configurations like so:

export default new Router({
  base: '/app',
  mode: 'history',
  routes: [
    {
      path: '/',
      name: 'RangeInputDemo',
      component: ComponentDemo
    }
  ]
})

Adding base as '/app' made no difference to the routing that happened throughout the project, as if the base was still set to '/'.

I tried to change the url from the server side (the url at which the project is being served).

So in dev-server.js where :

var uri = 'http://localhost:' + port 

controls the url of the app, I made a slight modification to:

var uri = 'http://localhost:' + port + '/app'

This caused the application to show:

Notice the fullPath being '/' in the vue console (second image).

Just for double checking, I changed the base to '/' again.

So, the base property of the router configuration is to set the base url as set by the server, if the server serves the application at a route other than '/' then the base can be used for having the application be run from the set url.

Since the question requires the routes being moved under /app, I think having /app as the parent route would be the solution in that case, if the server isn't supposed to change the route on which it serves.
