Comparing connect vs. express vs. feathers vs. loopback vs. sails

It’s unopinionated because a software engineer isn’t limited to using hardwired development practices, so it provides much freedom. For instance, Express doesn’t dictate any of the design patterns (MVC, MVP, MVVM, 87 Commonly Asked Data Science Interview Questions etc.) This allows engineers to build applications their way. And yet Express is commonly applied within the MVC pattern. Node.js Sails framework is best suited for creating data-heavy enterprise-grade apps.

Koa is another incarnation of minimalism by the developers of Express. The goal of Koa is to reduce the middleware bundle that was in Express and give even more freedom to engineers without any automation. Sails.js takes the middle ground between automation and engineering freedom, which makes it perhaps one of the most balanced options in Node.js development.

Meteor is another popular framework, which sits on the opposite pole of the Node.js globe. Unlike Express.js, Meteor takes standardization and out-of-the-box philosophy to the extreme. The package arms an engineer with integration tools that are sufficient for building server, mobile, web, and desktop apps.

Your First Sails Project

Writing policies encourages encapsulation, which dramatically simplifies your business logic and reduces the total amount of code you need to write. Policies are interchangeable with Express/Connect middleware, which means you can plug in popular npm modules like Passport. Finally, like most things in Sails, your policies work for both WebSockets and HTTP automatically. It doesn’t apply any of the prevalent design patterns such as MVC, MVP, MVVM or whatever is trending out of the box. For fans of simplicity, this is a big plus among all other frameworks because you can build your application with your own preference and no unnecessary learning curve.

Sails uses Express for handling HTTP requests, and wraps for managing WebSockets. So if your app ever needs to get really low-level, you can access the raw Express or objects. Another nice side-effect is that your existing Express routes work perfectly well in a Sails app, so migrating an existing Node app is a breeze. Like other MVC frameworks, Sails is built with an emphasis on developer happiness and a convention-over-configuration philosophy. Building on top of Sails means your app is written entirely in JavaScript, the language you and your team are already using in the browser.

Is there any framework for Node.js?

Instead of trying to figure out how each of these frameworks stack against one another, we will see the key areas in which each of these frameworks excel and how they are relevant to various project needs. Express.js is one of the best, as well as the most popular Node.js framework. Express is a Node.js web application framework that provides a plethora of functionality for developing web and mobile applications. It is used to develop online applications that are single-page, multi-page, or hybrid in nature. LoopBack is the brightest representative of REST API frameworks.

One way to flatten callback nesting is to use Async.js. When writing Node.js code with Async.js, the indentation of code still tends to drift to the right, just not as deep. Their ORM feature enables Web frameworks to be integrated with any database management system. It may configure middleware, enabling developers to respond to HTTP requests. For example, if a user is filling a form, it will be pushed to all other browsers in realtime.

We’ll also try to provide hints on when to use this or that framework. In addition to Express.js, Sails.js is closely linked to, 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. Sails.js is a Node.js library built on top of JavaScript runtime and modeled after the server-side web application framework Ruby on Rails. From a feature standpoint, Feathers and Sails are probably the most similar of the comparisons offered here.

Koa is developed by the team behind Express, and its goal is to minimize the minimalist Express by not bundling any middleware within its core. Other than being middleware-less, Koa looks very similar to Express, lightweight and un-opinionated. However, what makes Koa truly standout is its way to ditch callback completely by using the ES6 Generator feature. Middleware are basically just functions that have full access to both request and response objects. Toptal handpicks top Node.js developers to suit your needs.

Main Koa.js features to look at

It helps the system to retrieve and manage data conveniently. A Socket.IO is well integrated with the Sails functionality. The scoring part is that users can change this socket according to their preference by disabling it first.

Express is a basic routing engine with some helpers, where as sails is a full MVC framework. An apple pie is nice and is a lot more developed than a simple apple, but you can’t do something else with it. However, one drawback of Waterline is that you are not allowed to define embedded objects/documents as you can do in Mongoose. Software Development Team: Structure & Roles One to Many, Many to Many and One to One can be implemented beautifully with waterline as compared to mongoose. As experienced or new developers, we know that Express is the most commonly used NodeJS Framework. But, we can conclude that Sails and Meteor are also playing a competitive role in the developer community.

  • One to Many, Many to Many and One to One can be implemented beautifully with waterline as compared to mongoose.
  • Some third party Promise libraries with reputation are bluebird and q.
  • Statistic shows that the number of websites made using sails.js is increasing with time.
  • Hapi has the ability to create a server on a specific IP with several features, such as onPreHandler.
  • Partner with us to redefine your business values with futuristic digital transformation and unprecedented growth.
  • You are looking at the website for the fully functional Feathers v5 pre-release.

In the past, adding realtime/”comet” features meant maintaining two separate code bases. But since the request interpreter in Sails translates incoming socket messages for you, they’re automatically compatible with every route in your Sails app, as well as any existing Express routes/middleware. Normalization of parameters, the session, and the streaming interface are all taken care of. In other words, the code you write works with WebSockets and HTTP, without doing any extra work.

What Are the Advantages of Sails.js?

These are defined elaborately in the Code of Conduct of Node JS. Adhering to these principles helps in the maintenance of the project. But there is a downside to which users must be acquainted. You cannot install or embed documents or objects using Waterline. The node js What is Express js same can be achieved with its competitor database Mongoose. There are numerous ways to configure databases using Waterline as several adapters are available on npm. When a developer uses Waterline, he or she is open to using different search query databases.

Meteor integrates with Angular or React.JS to connect Node.js back-end with applications on the front-end. It uses MongoDB as storage and can be integrated with Cordova to build hybrid applications using HTML, CSS, and JS running through WebView. While you can swap most parts from the stack, this packaging streamlines much of the ground-work.

The introduction and rapid growth of Node.js everything has changed. First of all, it lets developers build the server-side of the apps in JavaScript. As a minimal framework, Express does not consider database integration as a required aspect within its package, thus it leans toward no specific database usage whatsoever.


We can create both single-page and multi-page web apps using Express. When I code with sails I waste much time and hard to learn. It’s worth noting that Sails is built on top of Express, so with a little finagling any Express extension can work with Sails, and porting Express apps to Sails is not terribly involved.
