diff: router.isReady().then(() => app.mount('#app'))

  Otherwise there will be an initial transition as if you provided the `appear` prop to `transition` because the router displays its initial location (nothing) and then displays the first location. This happens because navigations are all asynchronous now. **If you have navigation guards upon the initial navigation**, you might not want to block the app render until they are resolved.
  -- On SSR, you need to manually pass the appropriate history by using a ternary:

  - `transition` and `keep-alive` must now be used **inside** of `RouterView` via the `v-slot` API:
  ```vue
  <router-view v-slot="{ Component }">
  </transition>
  </router-view>
  ```
  - See more on the [KeepAlive](https://github.com/vuejs/vue-router-next/blob/master/e2e/keep-alive/index.ts) and the [Transition](https://github.com/vuejs/vue-router-next/blob/master/e2e/transitions/index.ts) examples.

  - `parent` is removed from Route locations (`this.$route` and object returned by `router.resolve`). You can still access it via the `matched` array:
  ```js
  - const parent = this.$route.matched[this.$route.matched.length -1]
  + const parent = this.$route.matched[this.$route.matched.length - 2]
  ```
