Is it possible to keep multiple vue.js SPAs alive at once from launch?

Question

Vue.js

There is a single page application on vue.js containing 5 main pages. There are animations when transitioning between them. On a smartphone (even on snapdragon 845), when you first go to a page, there is a prolag of 200-300 ms, and when you go to this page again, everything is fine. All pages are in keep-alive, which means that reloading does not cause serious work from vue. I would really like all these 5 pages to be preloaded and active from the very start of the web application, so that everything works quickly when you first go to them. How can this be done?
