With Quasar CLI you can build your app with the killer combo of SSR + PWA. In order to enable PWA for SSR builds, you need to edit your /quasar.config file first:

return {
  // ...
  ssr: {
    pwa: true
  }
}

The first request of a new client will be served from the webserver (so SSR supplies the initial page content). The PWA gets installed then it takes over on client side. All further requests will be served from cache (unless you have some custom configuration to change that).

For more information on PWA, head on to PWA Introduction and read the whole PWA Guide section.
