What Is Sails.js? (Definition, Uses, Advantages)

Sails.js includes any data-oriented tasks you might need to build your application. In contrast to Ruby on Rails, Sails.js offers a modern, data-focused approach to building web applications, thereby implementing real-time features, such as a live chat option, for smooth customer experiences.

Why Use Sails.js?

  • Sails.js allows you to build RESTful APIs
  • Sails.js uses code generators
  • Sails.js allows you to add chat functions to your website


How Does Sails.js Work?

As a Node.js MVC (model-view-controller) framework, Sails.js follows the favored “convention over configuration” rationale, similar to Ember.js. However, to begin working with Sails.js, you’ll need to have a Node.js library and node package manager (NPM) installed on your desktop. You’ll also need to choose between a relational (SQL) or non-relational (NoSQL) database. A relational database is designed to recognize relations within stored data information. A NoSQL database provides an alternate method of data storage and retrieval that goes beyond that of a relational database’s typical structures.

What Are the Advantages of Sails.js?

While Ruby on Rails and Sails.js use the same MVC framework to help web designers build web applications and services, they’re used for completely different purposes. Ruby on the Rails is most frequently used by startup companies because, regardless of the coding language complexities, it’s easy for experienced users to create a website quickly. 

On the other hand, Sails.js differs from its model counterpart when it comes to performance. Sails.js is built on top of Express.js, a popular back-end web application software that creates RESTful APIs and interfaces that systems use to securely relay data online. Because Sails.js is interrelated with Express.js, it allows you to build RESTful APIs in very little time. Sails.js is also great for beginner developers because of the code generators it uses to construct your website. That’s all to say, if you use Sails.js, you won’t have to worry about writing a lot of code.

In addition to Express.js, Sails.js is closely linked to Socket.io, a JavaScript library that permits users to add real-time and event-based transmission to system features. This will allow developers to add a live chat function to their websites, a feature that will benefit e-commerce sites, for example.

What Are the Disadvantages of Sails.js?

The last stable release of the framework was Sails.js v1.0 in March 2021, so the framework’s development is a bit slow. There are annoying bugs that make it seem like the framework is in a perpetual beta status. Developers complain that starting the framework will take time. Additionally, developers argue that large data sets slow down web application operations. If you’re working on a big project, like a multiplayer game or an e-commerce website, Sails.js is a great framework to use for its performance and ability to handle large data sets, but keep in mind it’s still a work in progress.
