My new lightweight web framework Dance.jl supports this easily:
using Dance.Router
static_dir("/static", "files")
where first param is route prefix of how to serve (can be / too) and second param is name of the static files folder in web project dir to serve content from.
You would have to copy the static files dir to root of newly created web project dir, as for security dance.jl does not allow going higher than the project root.
