onPageTransitionStart is Server Side Rendered?

[Dubzer]

hii
is it possible to detect in onPageTransitionStart if the next page has SSR enabled in the config?

my use case is to display a loading bar at the top of the screen when the page is loaded so the user can see that the web app has reacted to their action and is just loading the next page.
but that's unnecessary with client-side rendered pages since the loading is instant, so I want to check for SSR before starting the animation

The +onPageTransitionStart hook is called only upon client-side navigation; it's never triggered for SSR. So it already does what you want, right?

i understand that it's never called on the server.
but it's called on the client including the case for transitioning to an SSRed page. specifically, I want to know that the next page will be rendered on the server.
that will let me know that the navigation will take a while, so i should display a progress bar

Upon client-side navigation, the next page is never SSR'd.

Would showing the progress bar if and only if +onPageTransitionEnd wasn't called after a certain amount of time be an acceptable alternative approach for you? I'm even inclined to say that it's a more robust approach.

that's not possible since the route isn't resolved when onPageTransitionStart is called. see #2453 (comment)
