Node.Js – an open-source framework based on the JavaScript runtime used for executing JS code. This is undoubtedly one of the quickest engines on the market and is based on the Chrome V8 Engine. 

Node.Js uses an event-based, onon-blocking I/O mechanism which helps it to be more efficient and lightweight.

Here are some interesting stats about Node.js:

  • StackOverflow predicts that in 2022, the platform and technology will be most widely used. 
  • The technology that is most desired in 2022 is in second place. 
  • 8th most popular platform by 2022. 

Companies that Use Node.js

Some of the well-known companies that use Node.js are:

  • Netflix: Netflix started using Node.js to provide high-volume web streaming to more than 182 million subscribers, and they hoped to expand their use of Node.js to include content creation. 
  • Uber: Uber’s primary trip execution engine was created in Node.js due to its simplicity, single-threaded processing and asynchronous primitives. 
  • PayPal: As a replacement for Java, PayPal decided to use JavaScript for web applications from the browser all the way to the backend server. 
  • NASA: Following a bad incident in orbit, NASA chose to employ Node.js to improve data security and maybe save lives. 
  • LinkedIn: Due to its scalability and performance effectiveness, LinkedIn ceased using Ruby on Rails and switched to Node.js.

Pros of Node.js

We’ve listed the most common of Node.js’s advantages:

1. Easy to learn

Node.js is based on JavaScript, so if you already have a strong foundation in programming and are familiar with JavaScript, learning it can be a lot simpler. There are lots of tutorials and courses available to make learning fun.

2. Community

A supportive and insightful community means a lot of engagement. There is a sizable developer community that supports Node.js. The Node package manager, or npm, is one of the most well-liked and quickly growing software repositories. You can use the many libraries and reusable templates provided in your project.

3. Seamless JSON support

While other backend technologies, like Ruby on Rails development framework, can communicate using the JSON format, Node.js does so by using JavaScript rather than converting between binary models. When building RESTful APIs using a NoSQL database like MongoDB, this is quite helpful.

4. Highly extensible

Since Node.js is well known for being highly extendable, developers can modify and extend it to suit the requirements of their projects.

Cons of Node.js

Here are some of Node.js’s drawbacks, that makes the framework, a lesser suitable choice for your project:

1. Unstable API

Node.js frequently experiences incompatible API changes. The biggest drawback of utilizing Node.js development framework is the hefty code modifications that result from these incompatibilities.

2. Immaturity of tooling

Despite the high level of dependability of the core Node.js modules, many of the packages in the npm repository are of poor quality and have inadequate documentation. Finding the ideal package for your needs may be challenging as a result.

3. Not suited for CPU-intensive tasks

The other significant flaw Node.js currently has is that it cannot handle CPU-bound activities. Only I/O-related tasks (like web servers) can use it.

4. Callback issue

Node.js heavily relies on callbacks, which are the processes that are launched once each task in the queue has been finished. Keeping a lot of queued processes running in the background, each with its own callback, has a direct impact on the quality of the code.

Let’s Compare Ruby on Rails and Node.js!

When selecting a web framework for your project, many things need to be taken into account. We will now compare the advantages that Node.js app development has to offer to those of Ruby on Rails. The following highlights the key distinctions between Node.js and Rails: 

1. Execution

The market for JavaScript has existed for many years. Therefore, Node.js can easily benefit from all the pre-built solutions and experiences that JavaScript has to offer. Node.js still falls short of the majority of comprehensive backend programming frameworks, though. As a result, Node.js takes a long time to execute problem problems to perfection.

Ruby on Rails, on the other hand, is one of the easiest web frameworks to use and learn. Numerous tools and syntactical features in Ruby on Rails allow for quicker development and execution.

2. Scalability

When we talk about of web app development, scalability is a major aspect. Node.js is very scalable because of its event-driven architecture and non-blocking I/O operations. It is useful for creating real-time applications like chat apps or online games since it can manage a huge number of concurrent connections very easily.

Compared to Node.js, Ruby on Rails is less scalable. It utilizes a single-threaded paradigm, which limits the number of requests it can process at once. However, by enabling it to handle multiple requests concurrently, tools like Unicorn and Puma are helpful. These tools help mitigate the limitations of the single-threaded architecture, thereby improving the scalability of Ruby on Rails-based applications.

3. Performance 

Due to its integration of JavaScript’s async and non-blocking features, Node.js fosters the development of manageable little jobs. Additionally, multitasking is quicker and more effective thanks to its V8 JavaScript engine. Node.js uses a single-threaded event loop architecture for backend programming. This guarantees that it manages several concurrent requests efficiently. 

Node.js has the capacity to handle several requests at once. The performance of this platform is preferred by several tech companies. For instance, after switching from Java to Node.js, PayPal experienced a doubling of requests per second and a reduction of 35% in the typical response time. 

In terms of performance, Ruby on Rails falls short of other popular web frameworks. Garbage collection is not effective enough for Ruby because it is an interpreted language. The garbage collector will occasionally enter the system, halt it, and use the mark-and-sweep algorithm to clear out memory that is no longer being referenced. This takes a lot of time and occasionally slows down the RoR app. However, it doesn’t happen often. 

That being said, hire Ruby on Rails developers to create fantastic web applications that perform well. The RoR development standards must be strictly adhered to in order to accomplish this. 

4. Application Architecture

The JavaScript callback mechanism and event-based model are the foundations of the Node.js processing model. Developers can also use the MVC/ MVP architecture pattern, which makes it easier for newcomers to onboard and isolate issues in the application codebase. Additionally, the platform supports asynchronous communication between its various components and generates multiple views of the same data.

On the other hand, Ruby on Rails makes use of the standard MVC (Model View Controllers) architecture. The model layer contains all the guidelines for managing data and storing business logic. The View is in charge of the application’s front end, and the controller is in charge of the application flow. Over the configuration rule, it adheres to convention. This indicates that the technological issues have already been resolved. So the concentration can be diverted more on solving business issues.
