what is +page.server.js on reload?

[jdgamble555]

After you load the route for "+page.server.js", and the route changes, does it call an RPC, does it create an endpoint, or does it just reload the whole route dynamically under the hood?

I know security is highly important, so wasn't sure...

You should be able to quickly test this to validate your concerns, but in my experience, it will invoke +page.server.js transparently under-the-hood (assuming this is not a static site).

I figured it out. It loads just the page data by calling YOUR/ROUTE/__data.json?x-sveltekit-invalidated=001. This will call the route, but only return the page server load data.

You can see this in the network tab when you navigate.
