Request (req)
Sails is built on Express, and uses Node's HTTP server conventions. Because of this, you can access all of the Node and Express methods and properties on the req object wherever it is accessible (in your controllers, policies, and custom responses).
A nice side effect of this compatibility is that, in many cases, you can paste existing Node.js code into a Sails app and it will work. And since Sails implements a transport-agnostic request interpreter, the code in your Sails app is WebSocket-compatible as well.
Sails adds a few methods and properties of its own to the req object, like req.wantsJSON and req.allParams(). These features are syntactic sugar on top of the underlying implementation, and also support both HTTP and WebSockets.

Built with Love
The Sails framework is built by a web & mobile shop in Austin, TX, with the help of our contributors. We created Sails in 2012 to assist us on Node.js projects. Naturally we open-sourced it. We hope it makes your life a little bit easier!
