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.
