  • How Sequel and Sinatra Solve Ruby’s API Problem (Publication)
    The rise of the web and mobile applications has led to an increased need for back-end API services. Ruby on Rails' philosophy seemingly makes it the ideal framework for creating back-end APIs. However, using Rails only for the API is overkill. In this article, Freelance Software Engineer Boško Ivanišević explores alternatives to Rails and introduces us to two very mature and powerful gems, Sinatra and Sequel, which in combination provide powerful tools for creating server-side APIs.
