How to notify the application about a new version (and force it to reload)?

Question

JavaScript

Good afternoon!
There is a SPA application, scripts and styles are added to index.html when building, with contenthash in the file name.
The index.html itself is not cached.
After deploying a new version of the application, there are two problems:
1) Previously opened clients use the old code.
2) Dynamic requests for individual bundles fail because these files have a new name.
A simple solution suggests itself - force a page reload, or ask the client to do so.
But what is the best way to notify about code changes?

Answer 1

add a separate query that returns the current version, let the client periodically compare its own and the current one
