module Proscenium
class Middleware
# This middleware handles requests for assets in Rails engines. An engine that wants to expose
# its assets via Proscenium to the application must add itself to the list of engines in the
# Proscenium config options `Proscenium.config.engines`.
#
# For example, we have a gem that exposes a Rails engine.
#
# module Gem1
# class Engine < ::Rails::Engine
# config.proscenium.engines << self
# end
# end
#
# When this gem is installed in any Rails application, its assets will be available at the URL
# `/gem1/...`. For example, if the gem has a file `lib/styles.css`, it can be requested at
# `/gem1/lib/styles.css`.
#
