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.
