Sinatra is a DSL (Domain Specific Language) for quickly creating web applications in Ruby. It is a lightweight framework that allows developers to build simple and flexible web applications without the complexity of a full-stack framework. Sinatra is particularly popular among developers for its simplicity and ease of use, making it a great choice for small projects and RESTful APIs.
History
Sinatra was created by Blake Mizerany in 2007. The framework was designed to be minimalistic and to provide a simple way to create web applications with Ruby. Over the years, it has gained popularity among the Ruby community, especially for its ability to allow rapid development of web services. The philosophy behind Sinatra is to provide a simple interface to create web applications without unnecessary complexity.
