Hello World

This recipe will help you to setup a Hello World! response in your /hello path.
First you need an amber project generated with Amber CLI or from scratch.
First create a src/controllers/hello_controller.cr file and add this:
src/controllers/hello_controller.cr
class HelloController < ApplicationController
  def hello
    "Hello Amber!"
  end
end
Then add a new route in your config/routes.cr file:
Amber::Server.configure do |app|
  pipeline :web do
    # pipelines...
  end
​
  routes :web do
    # other routes,,,
    get "/hello", HelloController, :hello
  end
end
​
