Module: SimpleRouter::DSL

Defined in:
lib/simple_router/dsl.rb

Overview

Mixin that provides a Sinatra-line DSL frontend to the routing engine backend.

Meant to be minimal, simple and as magic-free as possible. When mixed in, only adds 5 class methods (#get, #post, #put, #delete and #routes).

Examples

# simple rack app

class App

include SimpleRouter::DSL

get '/' do
  'home'
end

get '/users/:id' do |id|
end

put '/:foo/:bar' do |foo, bar, *params|
end

def call(env)
  request = Rack::Request.new(env)

  verb = request.request_method
  path = Rack::Utils.unescape(request.path_info)

  action = self.class.routes.match(verb, path).action
  action.nil? ? [404, {}, []] : [200, {}, [action.call]]
end

end

Notes

Because the DSL is a simple mixin, it can be used in any class (i.e. not necessarily a rack app).
