Example showing running Falcon locally from a single file (IRC question about ditching config.ru)

app.rb

require "falcon/environment/rack"
require "roda"

class App < Roda
  route do |r|
    r.root { "wombat" }
  end
end

service "wombat-app" do
  include Falcon::Environment::Rack

  middleware do
    Falcon::Server.middleware(App.freeze.app, verbose:, cache:)
  end

  endpoint do
    Async::HTTP::Endpoint.parse("http://localhost:9292")
  end
