Fallback for Static Path Matching

[jalcine]

Looking at the examples for routefinder, I'm noticing that I can't do something like Router::new().get("/web/**/*", static_file_handler). A more complete example from my project:

        Router::new().get("/w/*", static_file_handler).get(
            "/",
            Box::new(|conn: trillium::Conn| async move {
                conn.with_header("location", "/w/").with_status(302).halt()
            }),
        )

My want to do that is to allow for complete URLs to be passed to the browser and for a fallback page for sorts to catch that and handle the client-side routing correctly (namely Svelte, in this case). The hope is that I can give it a specific path to StaticFileHandler but if none of the paths matched that I can tell it to use a specific path (that can potentially be checked at compile-time) to exist.

What I've done in the interim is have a special query parameter that my CSR app can detect and do the client side redirection for.

In the CSR app:

	onMount(() => {
                let goPath = $page.query.get('go') || (new URLSearchParams(location.search)).get('go');
		if (goPath) {
			goto(`/w/${goPath}`);
		}
	});

And in my app code:

            conn.with_status(Status::PermanentRedirect)
                .with_header("Location", format!("/w/?go=requests/{}", request.id))
                .halt()

I'm not certain I understand what you're looking for, but there are two ways to make a fall-through router match. One is to mount a handler at "*", and the other is to do (Router::new().get(…), StaticCompiledHandler::new(…)) — the router will only halt the conn if it matches a route, so any unmatched route will continue onto the next handler. In routefinder, there's no distinction between "**" and "*" in that "*" matches anything including slashes, all the way to the end of the path

If instead, the need is to be able to always serve a specific file from the static file handler, there are changes I can release today that always serve a specific file regardless of path if instead of calling StaticFileHandler::new with a path to a directory, you call it with a single file

The ability to always return a file if none matches would be excellent and I think solve the use-case I have here.

P.S.: I don't know why I didn't get a notification for this.
