Application Root URL

The root URL is the website top level url, i.e https://localhost:3000/ in our application case. It usually represents the domain URL of the website like https://dhanugurung.com.

In Rails, the root method defines where it should send us for the route /.

It is quite conventional to put the root route at the top of the config/routes.rb file as it is ideally the first route to be matched when we navigate to the site.

Let’s display the ideas listing when we navigate the root URL. To do that we need to update the root method in the config/routes.rb file as:

Rails.application.routes.draw do

  root 'ideas#index'
  resources :ideas, only: [:index, :show]

end

Now, if you open the url https://localhost:3000, it will display the list of ideas similar to https://localhost:3000/ideas/.
