rack_app

Playing around with a Rack compliant app.

This little app implements the Rack protocol.

Our apps MUST:

• Implement a #call method.
• Receive the env hash as the #call argument.
• Return an array with 3 elements:
  • HTTP status code
  • Response headers
  • Response body, as an enumerable object.

To start the web server, open your terminal and enter rackup.

The config.ru configuration file will require the app file you are going to use.

Use the use keyword to implement your middleware.
Use the run keyword to execute an instance of your app.
