Description

This seems like generic enough functionality it could make sense to put in HTTP.jl. I don't have an api figured out, but just as a placeholder/starting point

# ?serve_file
#     serve_file(path; mimetype="infer", extension="infer", ...) :: HTTP.Response
#     serve_file(stream::HTTP.Stream, ...) :: Nothing

using HTTP

function handle_file(req::HTTP.Request)
    return HTTP.serve_file("file.txt") 
end

Research direction
Review the linked implementations (PkgServer.jl, Genie.jl, Flask) for reference on serving files. Investigate the HTTP.jl source to understand how to integrate a serve file function, looking at existing handlers and the response type.
