HTTP serve a directory with dynamic runtime path

[PaulHax]

For the NRTK-Explorer trame app, I'd like to HTTP serve a directory of images that is changed at runtime. The serve module is enabled at startup to dish out the apps custom Vue component bundle, so later calls to server.enable_module({"serve": {"dataset": str(dataset_dir.absolute())}}) seem to be ignored.

Wondering how to HTTP serve another directory behond the initial?

enable modules needs to happen "before the server start".

Another option is to create a dynamic endpoint that can be registered at the beginning but where its behavior can be updated at runtime.

But if we go that route, we will run into an issue if we deploy such app in a docker context as at that point each trame server are just handling the WebSocket and none of the HTTP static content delivery.
