Terminal apps are cool, but you know what's cooler? Web applications! Let's try to port our Cookbook to a new web application using the sinatra gem.

Sinatra is what we call a web "microframework". It's basically a micro Rails, also following the MVC pattern. The app.rb file acts as the controller. The router layer is handled by Sinatra. We already created a controller method to handle the root of the web app. Sinatra maps the URL in the browser to the right method in app.rb. Take a look at the routing doc for more info.

Read more about Sinatra in our homemade tutorial. Follow the setup, sinatra app and views steps thoroughly before starting your Cookbook web app.

In our web app, we'll use our Recipe and Cookbook classes as we left them earlier. We won't need the Router and Controller classes though.

At the root of your web app (at the / url), you should display your cookbook's recipes in an unordered list.

Under the list of recipes, add a navigation link (<a>) to the /new url, that we'll use for the create user story.

Creating a new recipe takes two steps in the context of our web app. We need one step to display a form. We'll use a GET /new HTTP request to display the form.

The <form> will be the equivalent of the gets in the terminal. We need fields for the recipe's name, description, and any other field you find relevant to add. Submitting this form should trigger the following HTTP request:

POST /recipes

This request should trigger some code in app.rb to add the recipe in the cookbook. At the end of this code, find a way to redirect the user to the / url of your web app (the index).

In your index, add a destroy link next to the name and the description of the recipe. Clicking on the link should remove it from the cookbook and redirect to the index.

When you managed to code these 3 user stories, go on and try to implement the harder import and mark as done actions!

Happy Sinatra!
