So I noticed the callback function in the webview struct, but I don't think that's what I'm looking for. Namely, I would like to know if there's a way to intercept web events such as page redirects / navigation. A concrete example would be intercepting the redirect of an OAuth 2 application so that you can extract the state information the server returns.

Can't it be done by trapping the event within JS, then signalling the backend
via window.external.invoke_? Don't know if it would work for navigations or
redirects, though.

That's an interesting option... I didn't think of injecting JS into the web page I was loading to try to detect it that way.. I have no control over the content that's loaded within the page.. and I'd have to re-inject the JS every time the user navigated until I detected what I needed.

That's right. And the beforeunload event that needs to be handled does not
seem to fire on macOS.

There are indeed native callbacks for navigation-requests on each platform. It
is only a matter of hooking a common callback to each of them.
