Scripts integration query argument

[vralle]

Hi!
I am reviewing WP_Service_Worker_Scripts_Integration->register()

The method uses WP Core filter script_loader_src and then adds the version value to the url. I have a question about the sequence of these actions.

The filter script_loader_src can be used anywhere for cleanup url. In this case, the cleaned url without additional arguments are included in the page markup. While the plugin will continue to use url with an additional argument.

Unfortunately, I did not have time to delve into the knowledge of how SW works to determine the correctness of this behavior. However, if the script preload links differ from the script markup links, this behavior results in an error.

If the filter fire last, the url may be the same.

Hi there. Yeah, I actually do not recommend using WP_Service_Worker_Scripts_Integration. As noted in the wiki, the integrations are experimental and I intend to deprecate them (#403). A problem with WP_Service_Worker_Scripts_Integration is that it precaches scripts even if those scripts never get used. It is normally preferable rather to use the runtime cache to instead cache scripts that are actually used.
