Ruby developers can now create REST APIs from JSON files using meta-programming. The AutoAPI project, showcased in a recent blog post, allows users to define endpoint specifications in a JSON file and automatically generate routes for those endpoints using Sinatra. This means that Ruby developers can quickly build RESTful APIs without writing extensive code.

The article highlights the power of meta-programming in Ruby, which enables programs to treat other programs as data. By leveraging this technique, AutoAPI simplifies the process of creating REST APIs, making it more efficient and productive for developers.
