Creating a RESTful API should be the easiest part of your development. You should not have to be a rocket scientist to successfully create a RESTful API. With Sails, you can create a full featured RESTful API in just a few minutes without writing any code. You get create, destroy, update, find, paginate, sort, and filtering out of the box. If you need to add your business logic to any of the methods or create your own methods, you can do that by writing simple JavaScript functions. Once you are ready to implement security, Sails provides policies that can be applied to any REST action to implement email/password, social login or Windows authentication. For data storage, Sails bundles the power ORM, Waterline, which provides a simple data access layer that just works, no matter which one of the more than 30 data storage providers you are using. This talk will be code heavy as we walk through getting started with Sails and demonstrate how to implement the features of Sails through the creation of an API. As well, I will share the tips and tricks that I have learned using Sails at a Fortune 100 company. You will walk away understanding how and why you should use Sails on your next project. All code covered in the talk with be immediately available for download.
