01:54 - The problem

• This only affects the client-side

05:28 - What are some solutions:

• Do nothing and hope the user refreshes.
• Have a list of assets, or commit hashes. Poll the server periodically, and when there is a new version available:
  • Prompt the user to refresh
  • Just refresh the user (store current state in localstorage and restore)
• Do a custom component, that checks the last time the user has refreshed (or if new version if available). When they click the link, render a regular instead of a pushstate link.
• Use a service worker. They will emit an event when a new version is available. Use the above methods to refresh the user.
• Hot code push.
  • Vuepress has "hot reloading" baked in.
