Overlapping routes with nest("/", _)

[wooden-worm]

I wanna port an existing web app to axum, but having problems with overlapping routes. The problem is I wanna serve static files under /. The routing logic is essentially:

• Check for dynamic content first, if not
• Check for the static file

I can't use .nest("/", get(static_file_svc)).nest("/app", app::routes()) due to non-overlapping route rule.

My questions are:

• Is this something axum will support in the future?
• I think I can work around the problem by defining an catch all route .nest("/", my_svc), and in my_svc manually implement the above routing logic. Is this gonna work, considering the dynamic routes have to handle both get and post requests?

This exact use case was mentioned in the changelog actually:

• added: Router::fallback for adding handlers for request that didn't match any routes. Router::fallback must be use instead of nest("/", _) ([Stores routes in a map #408])

So this should work .fallback(static_file_svc).nest("/app", app::routes()). The order doesn't matter. You might also wanna update to static_file_svc to return some meaningful response for non-GET requests, probably 404.

Ah that's perfect, thank you!
