It is designed to make it easy to build custom, enterprise-level applications by providing a robust structure and a rich set of features. Sails.js is particularly well-suited for developing data-driven APIs and real-time applications.

History

Sails.js was created by Mike Mclin in 2012 and has since gained popularity among developers looking for a full-featured framework for building Node.js applications. Inspired by the Ruby on Rails framework, Sails.js incorporates similar conventions and principles, making it easy for developers familiar with Rails to adapt to this JavaScript-based framework. Over the years, Sails.js has evolved with contributions from a vibrant community and regular updates that have enhanced its capabilities and performance.
