Ruby on Rails

Ruby on Rails (simplified as Rails) is a server-sideweb application framework written in Ruby under the MIT License. Rails is a model–view–controller (MVC) framework, providing default structures for a database, a web service, and web pages. It encourages and facilitates the use of web standards such as JSON or XML for data transfer and HTML, CSS and JavaScript for user interfacing. In addition to MVC, Rails emphasizes the use of other well-known software engineeringpatterns and paradigms, including convention over configuration (CoC), don't repeat yourself (DRY), and the active record pattern.

Ruby on Rails' introduction in 2005 influenced web app development through features such as seamless database table creations, migrations, and scaffolding of views to enable rapid application development. Ruby on Rails has continued to influence other web frameworks in other languages, including Django in Python; Catalyst in Perl; Laravel, CakePHP and Yii in PHP; Grails in Groovy; Phoenix in Elixir; Play in Scala; and Sails.js in Node.js.

Well-known sites that use Ruby on Rails include Airbnb, Archive of Our Own, Crunchbase, Dribbble, GitHub, Twitch and Shopify.
