Introduction To Ruby on Rails

Ruby on Rails is a web framework based on the Ruby programming language. Pragmatic and robust, Rails is used for the server-side development of performative websites and web applications. It follows MVC architecture to offer data consistency, abstraction, reusability, and testability.

what is ruby on rails?

Developed in 2005, Ruby on Rails is a front-end framework that can build large web-based applications that support heavy user traffic. It is a collection of libraries containing code snippets and reusable modules called Gems. The framework, believing in the ‘Convention Over Configuration’ approach, offers an easy-to-use environment with in-built conventions to RoR developers. For more information check out our other Ruby on Rails blogs.

Some features of Ruby on Rails are –

  • Don’t repeat yourself’ approach is followed, offering reusable components and modules to perform common tasks, such as a menu dashboard design or a contact form.
  • Model View Controller(MVC) architecture – Allows demarcation between application logic and presentation layer.
  • Support for regressive and unit testing – Automated tests are created by Rails for your program.
  • It comes pre-installed with RubyGems.
  • Object-Oriented concepts of Ruby are applied for better readability and manageability.
  • Best coding practices employed to increase the productivity of programmers and deliver quick results.

A Brief: What Is Node.JS?

Node.JS is a JavaScript runtime environment that is used for executing server-side code. It is not a framework like Rails, but it assists developers in server-side development using the popular scripting language JavaScript. Running on the V8 engine, it can execute a JavaScript program outside a web browser.

what is nodejs?

Node.JS was developed to be a lightweight solution for web app development. Being a custom Node JS development company we use it for building scalable, high-performing apps. With a huge community of supporters, many popular companies use Node.JS in their technology stack. Corporations, such as GoDaddy, Groupon, Microsoft, and Amazon Web Services, use Node.JS as their JS runtime system.

Some features of Node.JS that make it such a popular choice are-

  • Event-driven – An event managing system keeps track of the responses the server is to receive from already executed APIs
  • Asynchronous – A Node.JS web server is asynchronous, meaning it doesn’t wait for a response from APIs 
  • NPM package manager – Inbuilt tool for package management that provides modules 
  • It uses a single thread for different connection requests, thus improving RAM usage and offers high scalability
  • Node.JS uses non-blocking input-output (I/O) calls that support multiple concurrent connections to be held in the event loop.
  • Avoids context switching process between threads, thus optimizing speed and performance

Ruby on Rails VS NodeJS – 6 Major Differences

  1. Performance and Speed

    Node.JS websites and applications are exceptionally fast. Its usage of single threading for the execution of simultaneous racquets, and asynchronous processing, makes it a powerful development tool.

    In comparison, Ruby on Rails is generally slower. Rails work slower than Node.JS applications because it comes built with many default utilities and functionalities. Although developers don’t spend time writing each component from scratch, it also makes the framework monolithic and slows down the speed, especially for small websites.

    Although performatively slow, Ruby on Rails has a rapid development speed. It is very easy to start and develop a project as you have all the necessary tools for your access.

  2. Libraries and Tools

    The main reason web developers like working with modules are their reusability. You can also break down a complex piece of code into manageable chunks. Both Ruby on Rails and Node provides modules and packages for this purpose.

    The package library in Rails is called Ruby Gems. Node.JS, on the other hand, has the NPM (Node package manager) that provides libraries and packages to automate tasks and avoid repetitive coding. Both RubyGems and NPM provide a standard format for developing npm packages with easy installation and version control.

  3. Gem VS NPM

    Gems are open source libraries of code and documentation that can be used in your program without explicitly adding it to your code. With an open-source community, there are Ruby on Rails experts who contribute new Gems for implementing new functionalities. Some common Gems are Rake, Bundler, RSpec, and Devise.

    For more information, you can read our blog Top 20 Ruby on Rails Gems to Use in 2021.

    NPM is a subsidiary of GitHub, which contains packages and libraries for working with JavaScript. Node.JS comes inbuilt with many modules that can be used without alteration. For other more unconventional tasks, NPM offers a command-line client for accessing and installing Node.JS modules. It is the most popular subsidiary for JavaScript developers.

  4. Usage

    Node.JS is used for implementing JavaScript in the frontend and backend. It is mainly preferred for building real-time applications. Many corporations, such as Shopify, Facebook use Node.JS in their web applications. It is a JavaScript runtime environment, unlike Rails.

    Ruby on Rails, on the other hand, is specifically used for the rapid application development of database applications. With a powerful ORM (Object Relational Mapping) system as ActiveRecord, you can quickly develop content-heavy websites that require heavy and rapid database manipulation with this backend framework.

    With its high productivity and DRF approach, you can also quickly create MVPs or Minimum Value Products prototypes of a full-fledged application. Contact us for getting custom RoR development services today.

  5. Community

    Both Node.JS and Ruby on Rails, being open-source, have a large, vibrant community. Having been in the market for so long, both have a cult of experienced developers and supporters.  With a bigger community, there is a higher chance of you receiving help and guidance.

    On Github, Ruby on Rails has 48.2K stars and more than 4200 contributors. Node.JS has 78.3K stars and 2959 committed contributors. While Node.JS clearly has more stars, the number of contributors of Rails is higher. Node.JS is the clear winner with a thriving community in this Node.JS vs Ruby on Rails comparison.

  6. Threading

    Ruby on Rails supports multi-threading. Rails can handle concurrent processing of multiple parts of a program code. This means Rails can utilize CPU time smartly and thus you can develop a very high functioning application. But for complex apps with many lines of code, it becomes tough to process multiple threads as the cost of context switching gets too high.

    Node.JS, on the other hand, works on a single thread just like JavaScript. Using a single thread handled by the Event loop in javascript, Node.JS continually executes processes to jump to the next thread instead of waiting for an I/O operation or memory access. This way Node.JS uses a single thread to provide fast, scalable applications.

In this criteria, there is a tie for Rails vs Node.JS. Both Node.JS and Ruby on Rails are suited for a particular type of application development.

Thus we come to an end to the Ruby on Rails vs Node JS comparison. As evident, there is no clear winner, with both the web development tools having their own set of advantages. These defining criteria may help you choose the right technology in your website tech stack.  It is important, along with differences, to also analyze your requirements before choosing the backend technology.

So let’s look at the advantages and disadvantages of using Ruby on Rails and Node.JS.

Pros and Cons of Node.JS Framework

Node.JS is very popular among JavaScript developers. Built on Chrome’s V8 engine, it is perfect for implementing JavaScript in the program code and the front-end of the website. Node.JS is so valuable in the development community because of the following benefits it offers –

  • It uses only JavaScript throughout the application- both server and client-side.
  • Lightweight, scalable and pragmatic, the environment is perfect for handling today’s fast-changing requirements.
  • Node.JS is an event-driven software that can be used for developing web servers.
  • Non-blocking I/O models ensure great scalability and high response time for user requests. Thus startups who require scalable websites should try using Node.JS.
  • JSON support -Node.JS interacts with JSON without converting between binary models. This is especially useful in building RESTful APIs with NoSQL databases.
  • Good for real-time applications like messenger chats, streaming websites, video conferencing apps.

But before choosing Node.JS, you should also consider the following drawbacks –

  • Sharing a single thread between all clients’ requests can lead to issues in the Node.JS applications.
  • High coding lines are required for simple tasks. NodeJS is not as productive or conventional as RoR.
  • Not suitable for heavy computations as it would result in the choking of the single event-loop thread and cause problems for all users. All incoming requests would be blocked until the current request can be completed.

Pros and Cons of RoR Framework

Rails is a widely used web development framework that provides many advantages to developers. With this server-side framework, you can create seamless web applications. In this section, we will discuss the benefits and pitfalls of using Rails for project development.

The benefits of using Ruby on Rails for your website project are –

  • As discussed, the DRY principle is very helpful in software development. When you are not repeating the same tasks, you save a lot of development time. Also, a single source of truth ensures that your code is easier to debug, maintain and integrate with third-party features.
  • Ruby on Rails imposes a lot of conventions. There is always a “Rails way” of doing things. This means it is extremely easy to have an up and running app in a matter of days.
  • High productivity is guaranteed when using Rails. It employs some of the best coding practices to remove unnecessary tasks. You spend less time writing code, and with fewer code lines you will have a more optimal website with exceptional code quality and features.
  • Ruby on Rails has a great database integration in the form of ORM. You need not write any SQL code or query as it will be directly mapped to database tables. Plus, RoR is also flexible with most of the popular database environments and translates SQL interactions on its own.
  • With the large community, the framework has attained, you can easily get customized RoR tools and libraries. Along with this, any questions you have will also be easily answered by many experts.

As with all, there are some downsides to the framework. Some disadvantages that you may face while using Ruby on Rails are –

  • It is not suitable for large applications that require a lot of dynamic interactions and high speed. Handling a large number of users might also lead to a problem with Rails.
  • Multiple threading has many advantages, but it can also slow down your application and may cause some lags. This is not an issue with newer versions, but Rail websites are still relatively slow.
  • Scalability is an issue with Ruby on Rails. If you are a startup, you might prefer to start small. But over time, when users increase, the Rails app might cause some issues, and you might need to migrate just like Twitter.
  • Rails is very opinionated. Although the conventions and defaults may help increase productivity, it is tough to stand out in the market and do something creative. The main problem is Rails makes it very hard to deviate from the convention and implement alternatives.

What To Use – NodeJS OR Rails?

As evident from the NodeJS vs Ruby on Rails battle, no framework is better than the other. It is up to you to decide which will be more suited for your development project.

ruby on rails or nodejs
