Powerful Duo of Node.js vs. Ruby on Rails: The Best Backend for Web Development

Choosing a technology to create your application is one of the most critical aspects of the entire project workflow. This is a vital choice for your development team, project, and future progress. However, many beginners do not know what to choose and on which platform it is better to base the application they will develop.

Two widely known technologies in the community are Ruby on Rails vs. Node.js. So, Node.js is a server-side JavaScript runtime environment with frameworks for building fast APIs (application programming interfaces), servers, desktop applications, and even robots. Ruby on Rails (RoR) is a web framework based on the Ruby programming language. RoR emphasizes convention over configuration, helping build clean and elegant code-efficient web applications.

When comparing Ruby on Rails vs. Node.js, we must realize that we can't make a general, one-size-fits-all comparison. These two technologies serve distinct purposes, each with strengths and weaknesses. However, what we can do is compare them with a specific focus on understanding their roles in backend development.

At Codica, we have a lot of expertise in using these two technologies because we have done many projects with them. For example, we developed an Online Service Marketplace for PlanMyKids with Ruby on Rails or Timebot for Slack with Node.js. So, both technologies are appropriate and always reliably serve our purposes. However, there are differences between Ruby on Rails and Node JS, which we will describe in this article.

Let's start our technical review tour!

Understanding Node.js

First, Node.js is an out-of-browser JavaScript runtime that allows you to write server-side code for web pages, applications, and command-line programs.

Node.js is not a separate programming language but a platform for using JavaScript on the server side. Using the platform, you can work with files, networks, databases, and other system resources on the server.

Regarding the language, the same JavaScript is used for both the frontend and backend. The only difference is in the set of APIs that frontenders and backenders use. Browser-based JavaScript uses Web APIs, which provide access to the DOM (Document Object Model) and UI (user interface) of pages and web applications. Server-side JavaScript uses APIs that provide access to the application file system, HTTP requests, and streams.

Moreover, Node.js can be installed on various platforms like Linux, macOS, and Windows. It is used to build multiple applications, including real-time chat applications, REST (representational state transfer) API servers, command line applications, and more.

Understanding Ruby on Rails

What is Ruby on Rails? So, Ruby on Rails, also known as Rails or RoR, is the most popular open-source web application framework written in Ruby under the MIT license. RoR was developed in 2004. It is known for its code efficiency and high speed.

Ruby on Rails was designed to help manage routines, business logic, data calculations, and other tasks. It is a web application framework well-suited for MVC (Model–View–Controller) web applications with support for databases and metaprogramming. According to David Heinemire Hanson, creator of Ruby on Rails, Ruby's original plan was about putting programmer happiness on top.

Most web servers that support CGI (computer-generated imagery) can run Rails. This platform supports MySQL, PostgreSQL, SQLite, SQL Server, DB2, and Oracle. Moreover, Ruby on Rails has a clear, concise, and flexible syntax similar to English. This lower learning curve makes the framework especially attractive to beginners.

Node.js vs. Ruby on Rails: background

In the ever-evolving landscape of web development, the choice between Node.js and Ruby on Rails has become a pivotal decision for developers. Let's start Node.js analysis first.

Node.js

The Node.js platform was introduced in 2009. Engineer Ryan Dahl created it, and Joyent sponsored the development. In general, Joyent supports open-source projects, including Node.js, Illumos, and SmartOS.

Ryan Dahl used the V8 engine to create Node.js. The platform is implemented with a low-level, non-blocking input-output (I/O) model built on an event-driven model. This means that Node.js can process multiple requests simultaneously without blocking other operations.

At the end of 2014, engineer Fedor Indutny, who was part of the core development team of the platform, created a popular fork of Node.js - io.js. The fork appeared due to the developers' dissatisfaction with the policies of the Joyent company.

The io.js platform was superior to Node.js in performance, but the creators of the fork decided to reunite with Node.js in 2015 to influence the development of the central platform. Currently, development is formally led by the Node.js Foundation.

Choosing server-side JavaScript for the backend provides the project with several benefits:

• JavaScript is one of the most popular programming languages. By learning JavaScript, you will be able to use Node.js to create web pages and develop server-side applications;
• You can increase development efficiency due to using one language for the frontend and backend development and the ability to reuse code;
• Also, Node.js uses an asynchronous execution model, allowing it to efficiently process multiple requests simultaneously (up to 10,000 active connections) without blocking;
• It allows you to create powerful server-side applications that handle client requests, work with databases, process files, and more.

Now, let’s move to the Ruby on Rails analysis.

Ruby on Rails

It is vital to understand that Ruby on Rails is an extension of the Ruby language, developed in 1993. The idea for this extension was formed in 2004. That year, when the entire world of the cyber industry was still an infant, the developer community sought something simple and basic. That's why Ruby entered the market.

Although it was very basic and simple, programmers worldwide agreed and were deeply convinced that this innovation would become one of the most promising projects among programming technologies ever created.

This is how Ruby found its community - one of the largest communities dedicated to programming technologies. By the way, this is one of Ruby on Rails' most critical positive aspects, and it can significantly influence your choice.

Below, we will consider a comparison of these popular technologies - Node.js vs. Ruby on Rails.

Before moving to a detailed review of each of the presented comparison components, let's refer to the table. From it, we can understand what criteria can be used to describe each technology.

Now, we proceed directly to the analysis of each aspect separately.

Scalability

Node.js excels in scalability with its non-blocking, event-driven architecture. It's like an ever-expanding highway system designed to seamlessly adapt to waves of traffic. This component makes Node.js an ideal choice for applications that predict exponential growth or need to manage numerous simultaneous connections. Its asynchronous nature allows it to manage multiple tasks simultaneously, ensuring that performance remains smooth even under heavy workloads.

On the other hand, Ruby on Rails, while certainly scalable, may require more configuration and optimization to achieve the same level of scalability as Node.js. The convention-over-configuration approach in Rails promotes a structured environment, which can sometimes demand additional effort for large-scale applications.

This model ensures that I/O operations don't block the execution of other tasks, resulting in rapid and responsive applications. It is built for speed and can easily handle real-time applications and data-intensive processes.

Ruby on Rails may not match the lightning-fast pace of Node.js. It operates more like a reliable and steady technology, offering good performance and consistent results, particularly for web applications that don't require real-time processing or asynchronous capabilities.

Community

Both Node.js vs. Ruby on Rails enjoy the support of powerful and active communities. Node.js boasts a dynamic ecosystem with many contributors, libraries, and packages available through npm. It overflows with resources and opportunities for collaboration.

On the other hand, Ruby on Rails has a well-established and loyal community. This community has a rich history and strong presence, offering valuable insights, gems, and best practices.

Flexibility

Node.js prides itself on flexibility, akin to a vast open landscape ready for exploration. Its ability to adapt swiftly to changing project requirements or new technologies makes it universal. Whether you're building a REST API, a real-time chat application, or a serverless function, Node.js can seamlessly adjust to your needs.

Ruby on Rails, while offering flexibility, follows a more narrow approach, primarily due to its convention over configuration. It provides a structured framework with predefined patterns, which can streamline development but may require developers to adhere more closely to these conventions. This structure ensures consistency but might be less adaptable to unconventional project requirements.

Cross-platform compatibility

In the realm of cross-platform compatibility, Node.js showcases its versatility. It is designed to run on multiple operating systems, including Windows, macOS, and various Unix-based platforms, making it an adaptable choice for developers working across different environments. This cross-platform capability allows for greater flexibility in deploying applications, ensuring they can reach a wider audience regardless of the user's preferred operating system.

On the contrary, Ruby on Rails, though not limited to a single operating system, primarily finds its comfort in Unix-based systems. This may require additional configuration and adaptations when deploying on Windows.
