== Features ==
Sails.js offers a host of features and attributes. Because it is built on Node.js and [[Express.js]],<ref name="toptal">{{Citationcite neededweb|datelast1=Yang|first1=Chuoxian|title=Comparison Of Four Popular Node.js Frameworks {{!}} Toptal|url=https://www.toptal.com/nodejs/nodejs-frameworks-comparison|website=toptal|publisher=Toptal, LLC|accessdate=22 July 2017}}</ref>, it enables applications to be built with 100% JavaScript. This not only includes models, views, and controllers; but also configuration files and adapters (e.g., database).
Like Ruby on Rails,<ref name=":1" />, Sails.js provides an [[ORM|Object-relational mapping]] interface, using [[Waterline.js]], which abstracts the database interaction.<ref name="toptal"/> This enables a uniform API regardless of the underlying database being used.<ref name="WaterlineJS">{{cite web|url=http://waterlinejs.org/|title=Waterline.js home page}}</ref>
A number of other packages are included to enable fast auto-generated [[REST API]]S, [[WebSocket|WebSockets]] by default using [[Socket.io]];<ref name=":1" /> and compatibility features making it front-end agnostic so that many tools and frameworks ([[AngularJS]], [[React.js]], [[Android]], [[iOS]], etc) are supported.
