app/controllers/posts_controller.rb
app/jobs/hard_job.rb
/tmp/jets/build/app_root/app/jobs/hard_job.rb
/tmp/jets/build/app_root/app/functions/hello.rb

def functions
  # Example: require: /tmp/jets/demo/app_root/app/controllers/admin/posts_controller.rb
  class_name = @full_path.sub(/.*\/app\/\w+\//,'').sub(/\.rb/,'') # admin/posts_controller
  class_name = class_name.classify # Admin::PostsController
  # Autoload instead of require to avoid accidentallly double requiring and
  # it resulting WARNINGs when there are constants already defined
  klass = class_name.constantize # autoload

  klass.lambda_functions
end

#handler_for(meth) ⇒ Object

This gets called in the node shim js template

Example return: “handlers/controllers/posts.js”

end

#process_type ⇒ Object

process_type is key, it will either “controller” or “job”. It is used to deduce klass, etc. We get the process_type from the path. Example paths:

app/controllers/posts_controller.rb
app/jobs/hard_job.rb
