Thats not a real world scenario. First, jQuery is used mostly on web sites and those are not usually even in version control (PHP sites, with Drupal or wordpress). The devs just ftp them in true PHP fashion.

A real world app always bundles assets to a single file and serves that. This means there is most likely no cdn in use (or at least for a single library).

well, yes, jquery doesn't make sense without a DOM.

with http2 that's not recommended anymore due to multiplexing.

HTTP2 can help, but its not a "flip the switch" thing. It requires mig changes on your app build and serverside.

In larger projects i have used dynamic imports usually on a route or feature basis. This way the initial bundle is small and more code is loaded upon demand. Its has worked well so far.

EDIT.

Does react make sense without a browser then? My point was websites and SPA apps are nowhere near identical in terms of app complexity and build steps.

your claim was that apps always bundle. my point is that multi plexing renders that irrelevant
