Sails.js tracking and usage

Sails.js is a Node.js web application framework designed to make it easy to build custom, enterprise-grade applications. Its main features include effortless data handling, auto-generated APIs, support for WebSockets, flexible asset pipeline, and easy integration with popular databases and other APIs.

Yes, Sails.js is frontend-agnostic, which means you can use it as the backend for any front-end framework or library, including React, Angular, and Vue.js. Sails.js primarily focuses on building the backend API and handling server-side logic, while you can use these front-end frameworks to consume the API and build your user interface.

Sails.js uses Waterline, an ORM (Object Relational Mapping) that enables you to connect and interact with a variety of databases (including SQL and NoSQL databases) without writing database-specific code. Waterline offers a unified API to work with databases, so you can switch between database systems without having to change your application logic.

Blueprints are a powerful feature in Sails.js that automatically generates RESTful API endpoints based on your models and controllers. With blueprints enabled, you can quickly create, read, update, and delete (CRUD) actions for your models, even without writing any code for the corresponding controllers. This saves you time and helps you develop your application faster.

Yes, you can integrate custom Express middleware into your Sails.js application. To do this, you need to configure your middleware in the `config/http.js` file under the `middleware` object. Add your custom middleware function and order it accordingly within the `middleware.order` array to ensure proper execution sequence in the middleware chain.
