Cuba Libre chico
I've been wandering in the Ruby world a year now, from Rails to Sinatra. But sometimes i'd really want things simpler and perhaps more clean of developing web applications. Specially when you can get something fast and get total control. Thats when i've found Cuba a great web framework.
In that spirit Cuba its a powerful web framework aiming simplicity, speed and clean syntaxt. Cuba inherits all its power from Rack and Rum but now overpowers it to make it even cooler. Being refactored some time ago now looks a lot like Sinatra routes, here's an example
require 'cuba'
Cuba.define do
# /
on "" do
res.write "Home page"
end
# /users/:username
on "users/:username" do |username|
user = User.find_by_username(username)
# GET /users/:username
on get do
res.write "Hello, i'm #{user.name}"
end
# POST /users/:username w/params[:user]
on post, param('user') do |query|
if user
user.update_attributes query
res.write "user: #{user.id} updated!"
end
end
end
end
This encourages a cleaner and simpler way of writing routes, besides it also includes the power of Tilt
require 'cuba'
Cuba.define do
on "register" do
@message = "Hello dude!"
res.write render("templates/register.erb")
end
end
I liked Cuba so much i started a little lib to include all the contrib of Cuba, and i called it cuba-sugar
Which adds some things not so much, just to make writing a little easier following the way Cuba is doing stuff right now.
require 'cuba'
require 'cuba/sugar'
Cuba.define do
on "faq" do
# You can output the return of the block as the response
as do
"This are the most common questions"
end
end
on "fancy" do
@captcha = 123456
as { render('templates/captcha.haml') }
end
on "coffee" do
# And you can choose what HTTP code and extra headers
as 419, {'Content-Type' => "text/teapot"} do
"I DONT KNOW :(((("
end
end
on "users/:username/json" do |username|
user = User.find_by_username(username)
as_json do
{
name: user.name,
location: user.location,
is_it_friday: Time.now.friday?
}
end
end
end
