Map URL routes to Ruby methods.

An example app is available at Rack Routing Demo.

Command line:
gem install rack-routing

Or add to your Gemfile:
gem rack-routing

Require the rack-routing file in an initializer:
require rack/routing

1. GET / => get_root
2. GET /foos/:id => get_foos (with @url_params)
3. POST /foos => post_foos

Create a config/routes.txt file to set up the routes.

Request: POST /foos/bar

routes.txt: POST /foos/:value

The @url_params is set to { value: 'bar' }

The Ruby request handler might look like:

def post_foos
  Foo.create @url_params
  Rack::Response.new 'Foo was created.', 200
end

Here is a second example request:

 POST /foos, { "bar":"baz" }

Since this request uses body params, the @params is set to { baz: 'bar' }

The Ruby request handler might look like:

def post_foos
  Foo.create @params
  Rack::Response.new 'Foo was created.', 200
end

rspec

or

bundle exec guard
