Keep-alive on a single route instaead of all routes in router-view

问题

if keep-alive is specified to router-view as below

<keep-alive>
    <router-view></router-view>
</keep-alive>

then all routes are effectively cached and reloaded when that route is revisited.

I'd like to be able to specify a keep-alive option on individual routes.

With many routes and only 1 or 2 that need to be kept alive wihout re-rendering caching all routes is useless

is there any method of doing so or any workaround available

New in Vue version 2.1.0, the include and exclude props for conditionally caching components. Note the use of the name option.

const Foo = {
    name: 'foo',
  template: '<div><p v-for="n in numbers">{{ n }}</p></div>',
  data: function() {
    return {
        numbers: [Math.round(Math.random() * 10), Math.round(Math.random() * 10)]
    }
  }
}

const Bar = {
    name: 'bar',
    template: '<div><p v-for="n in numbers"><strong>{{ n }}</strong></p></div>',
  data: function() {
    return {
        numbers: [Math.round(Math.random() * 10), Math.round(Math.random() * 10)]
    }
  }
}
