Hot module reloading

[Dale-Black]

Is there a way to start the server using HTTP.serve() that watches for file changes in the directory and restarts the serve for those changes? I am trying to figure this out for Oxygen.jl, which uses this HTTP.jl under the hood. (OxygenFramework/Oxygen.jl#122 (comment)). Any help is greatly appreciated

This functionality only needs to work for .jl files so maybe Revise.jl can already accomplish something like this?

I think Revise.jl does have the ability to watch for changes on .jl files. the question then is writing an idempotent callback so you could track a global server that's been open, close it, adn restart it on each .jl file change. Doesn't sound too hard to wire up, but also not sure there's anything in HTTP we need to do/change in order to support.
