If you are looking for a Node.js framework that can help you build scalable, data-driven, and realtime web applications, you might want to check out Sails.js. Sails.js is a MVC (model-view-controller) framework that follows the "convention over configuration" principle. It's inspired by the popular Ruby on Rails web framework, but with support for the requirements of modern apps: data-driven APIs with a scalable, service-oriented architecture.

In this article, we will explore what Sails.js can do for you, how to install it and create a new project, and how to use it in action. We will also show you how to test and deploy your Sails.js applications, and how to learn more about this amazing framework.
How to use Sails.js in action
Sails.js provides a powerful set of tools and features that make web development easier and faster. Let's take a look at some of them.
How to create models, controllers, views, and routes with Sails.js
Models are the core of any web application. They represent the data and logic of your app. With Sails.js, you can create models using the built-in ORM (object-relational mapping) tool called Waterline. Waterline allows you to define your models using a simple JSON syntax, and it automatically creates the database tables and schema for you. You can also use any database you want with Waterline, as it supports SQL, NoSQL, and even custom adapters.
To create a model with Sails.js, you can use the sails generate command in your terminal. For example, if you want to create a model called User with attributes name, email, and password, you can type:
sails generate model User --attributes name:string,email:string,password:string
This will create a file called User.js in your api/models folder. You can edit this file to add validations, associations, or custom methods to your model.
Controllers are the components that handle the requests from your clients. They contain the actions that perform some logic on your models or other services. With Sails.js, you can create controllers using the sails generate command as well. For example, if you want to create a controller called UserController with actions create, find, update, and destroy, you can type:
sails generate controller UserController --actions create find update destroy
This will create a file called UserController.js in your api/controllers folder. You can edit this file to add your business logic to each action.

List of users
Routes are the mappings between the URLs and the controllers. With Sails.js, you can define your routes using a simple JSON syntax in your config/routes.js file. For example, if you want to map the URL /users to the find action of the UserController, you can type:
module.exports.routes = 'GET /users': 'UserController.find' ;
Sails.js also provides a feature called blueprints, which automatically generates RESTful routes for your models and controllers. This means that you don't have to write any code to create basic CRUD (create, read, update, delete) operations for your app. You can enable or disable blueprints in your config/blueprints.js file.
