I don’t use a framework in my web projects; just the included web
modules and sometimes the fibers web server.  I keep everything
stateless so that I can spin up many workers (i.e. Guile processes
with a web server listening on one of a range of local ports) and
dispatch to them from a reverse proxy such as Nginx or Lighttpd.

I configure an assets directory and define a procedure that sanitizes
the requested file name to serve it from that directory.  I don’t do
much with files so I don’t usually do anything other than

    (call-with-input-file file-name get-bytevector-all)

for the body of the response.  But if I had to send large files I’d use
“sendfile” directly.

Lighttpd seems to be lighter than Nginx.  If all you want is serve
static files upon request I’d use just Guile, matching on the request,
looking up the file in a declared directory, and using sendfile to push
it to the requester.
