Sinatra is a free web framework and a domain-specific language written in Ruby . It's an alternative to other Ruby frameworks like Ruby on Rails , Nitro , Camping, and Rango . Sinatra requires the rack web server interface.
Sinatra was designed and developed by Blake Mizerany and is meant to be compact and flexible. It does not follow the MVC pattern used in other frameworks such as Ruby on Rails. Instead, Sinatra aims to be able to develop web applications quickly and with minimal effort.
Some major companies use Sinatra, including Apple , the BBC , LinkedIn , Engine Yard , Heroku , GitHub, and Songbird . Heroku is providing a large portion of Sinatra's funding.
Sinatra was created in 2007 and placed under an open source license .
Examples
Example 1: a webapp in a file
A hello world web application can look like this, for example:
#!/usr/bin/env ruby
require 'sinatra'
get '/' do
redirect to('/hello/World')
end
get '/hello/:name' do
"Hello #{params[:name]}!"
end
Such a program is started with:
$ ruby test.rb
If you open it in the browser:
http://localhost:4567
Can you read the Hello World! see in the browser window. However, if you call the URL
http://localhost:4567/hello/Ada
so you can read the Hello Ada! see in the browser window.
Example 2: HTML code in the web app
It is possible to incorporate HTML code into the source code with ERuby (erb):
#!/usr/bin/env ruby
require 'sinatra'
get '/' do
erb :main
end
__END__
@@main
<!doctype html>
<html >
<head>
<title>Welcome page</title>
<meta charset="utf-8">
</head>
<body>
<header>
<h1>Welcome World!</h1>
</header>
<p>Welcome to this Website!
</p>
</body>
</html>

In July 2011, an individual or group posing as members of the Sinatra team discredited the Dancer Project. This incident led the Sinatra team to publicly endorse the Dancer project and other replicas.
