Intro to Sail.js
The document presents an overview of the Sails.js framework, highlighting its features like MVC architecture, RESTful API generation, and real-time integration with Socket.io. It provides insights into creating a new Sails project, model associations, and implementing policies for user authentication. Additional resources for documentation and community support are also shared.
