Examples

Complete servers live in examples/ in the repo. From a checkout:

bundle install
bundle exec ruby examples/puma.rb
bundle exec ruby examples/falcon.rb

The Sinatra and Grape examples need their adapter gems, which live in separate bundles (their dependencies conflict), so run them through those gemfiles:

BUNDLE_GEMFILE=gemfiles/sinatra.gemfile bundle exec ruby examples/sinatra.rb
BUNDLE_GEMFILE=gemfiles/grape.gemfile   bundle exec ruby examples/grape.rb

All of them listen on http://127.0.0.1:9292.
