Pros and Cons—Nodejs vs Ruby on Rails

Pros of Node.js

  • Unopinionated: Builds everything from scratch with fewer restrictions, which gives developers the freedom to code their own way. 
  • Non-blocking I/O System: Lets you process several requests simultaneously, resulting in more scalability and faster performance. 
  • Active Community: Allows access to readily available solutions and codes that makes easy for startups and beginner developers. 
  • Easy to learn: Developers with an experience in Javascript as a frontend language can easily adapt to the framework.
  • Full-Stack Privilege: Allows Node.js developers to write frontend and backend both in Javascript. This enables smooth deployment of apps and reduces the learning curve. 
  • Caching facility: Caches single modules in the application memory and eliminates the need to re-execute the code for faster response times. 
  • Extensive support: Assists developers with commonly used tools for different purposes such as testing or identifying project dependencies. 

Cons of Node.js

  • Productivity loss: Since everything needs to be written from scratch, you may experience a decline in productivity. Beginners find it difficult to build apps from scratch due to its unopinionated nature. 
  • Not suitable for extensive computing: Although Node.js supports complex apps, it doesn’t fare well with heavy computing (CPU intensive) apps. Additionally, it is less efficient at heavy calculations as it doesn’t support multi-threaded programming. 
  • Difficult to maintain code due to Async nature: Due to nested callbacks in Node.js and its heavy reliance on asynchronicity, it becomes tedious to maintain and difficult to understand code.
  • Some of its tools lack quality– Some Node.js tools don’t match high-coding standards and are not correctly structured due to its open-source ecosystem.

Pros of Ruby on Rails

  • Shorter development time: Ruby comes with strong adherence to ‘convention over configuration.’ The framework’s developer-friendly and object oriented nature also helps reduce the development time significantly.
  • Pocket friendly: With lesser time spent at the development stage and access to a rich talent pool of RoR developers, you can easily save some bucks on the project. Additionally, the open-source nature of the framework also saves you some licensing fees.
  • Supportive community: The community supports other members through ‘gems’ and helps with bug fixes and security concerns.
  • Smoother production cycle: RoR sticks to the gold standards of development and follows the convention over configuration features, resulting in fewer bugs in production and in general.
  • Easy testability: It automatically creates skeleton code while the developer creates models and controllers.

Cons of Ruby on Rails

  • Slow run-time speed: It gives a slower run-time speed compared to some of the other backend frameworks. However, most performance issues stem from improper database management.
  • Lack of flexibility: Things might start getting difficult as you stray away from a standard web application. RoR doesn’t provide much room for customization of dependencies and modules.
  • Amplifies mistakes: Architectural mistakes at the initial development stages could haunt you later. You need to lay a solid foundation to build an effective RoR application.

Performance and speed comparison—Nodejs vs Ruby on Rails

While performance should not be a killer factor for small projects, it becomes extremely important to consider it when building complex and large projects. With that being said, let’s compare Node.js and Ruby on Rails in terms of performance.

How does Node.js stand out in terms of performance?

As it inherits the asynchronous and non-blocking from Javascript, Node.js creates a perfect environment for small tasks (micro-operations/tasks) that don’t affect the main application thread. What’s more, with the V8 Javascript engine, multitasking becomes more efficient and functions at a lightening speed. 

The framework processes many requests simultaneously compared to other backend solutions. In fact, a large number of tech giants are turning towards Node.js for its performance. Paypal, for one, saw a 35% drop in the average response time and doubled their requests per second. Another such example is Linkedin that reduced its servers from 30 to 3 as they migrated to Node.js. Now doesn’t that speak volumes?

How does Ruby on Rails stand out in terms of performance?

Ruby on Rails is by no means the most performant or fastest backend framework out there. There are a few fundamental properties, Ruby as an interpreted tool and garbage collection, that slow down RoR application under specific circumstances. However, such instances happen only in rare cases like when the traffic scales significantly.

Having said that, Ruby on Rails is able to create efficient web applications with satisfactory performance in most cases. All you need to do is ensure the adherence to development standards, and the rest is a smooth sail.

Application architecture—Nodejs vs Ruby on Rails

When choosing a framework, it’s important to choose flexibility and avoid any strict enforcement of architecture and guidelines.  As a matter of fact, it’s always recommended to treat a framework as a guide, not methods, and standards. That said, let’s juxtapose Node.js and Ruby on Rails with each other and check whether they are flexible in terms of architecture.

What kind of architecture does Node.js support?

Under the hood, Node. js leverages the Single-threaded Event Loop architecture that enables it to handle multiple concurrent requests with high performance. However, Node.js also lets you use MVC/ MVP architecture pattern, which eases isolating and onboarding issues in the application codebase. In addition to this, it creates multiple views for the same data and supports asynchronous communication between various components. 

Here’s how you benefit from the async architecture of Node.js:

  • Processes multiple concurrent requests simultaneously and offers high performance. 
  • Ensures faster and flexible development of modules.
  • Reduces time-to-market of applications.

What kinds of architecture does Ruby on Rails support?

Ruby on Rails follows the prevalent MVC (Model View Controllers) architecture. The model layer is where you state the rules to manipulate data as well as store business logic. The view takes care of the application’s front end, whereas the controller is responsible for the application flow.

The architecture allows for easier testing and decoupling at later stages because of convenient separation of concerns. Ruby on Rails also follows the convention-over-configuration principle. It leads to lesser legwork for developers as it means the framework has already made some decisions for them.

Scalability—Nodejs vs Ruby on Rails

Frameworks significantly influence the web application scalability, therefore, the right choice of framework is important. Here’s how Node.js and Ruby on Rails stand out in terms of scalability.

How scalable is Node.js?

Node.js builds highly-scalable applications. The non-blocking I/O and event-driven model handles multiple concurrent requests. Moreover, the event-loop mechanism enables the server to process maximum requests. What’s more, Node.js makes the best compatibility with microservices by segregating applications into smaller parts. That way, it’s efficient to allocate tasks among different development teams and build applications more quickly and scalably.

Is Ruby on Rails scalable?

It’s possible to scale with Ruby on Rails, but the process requires you to invest more resources as compared to some of the other leading backend frameworks. A lot of questions were posed on RoR’s scalability when Twitter switched from the framework. However, applications like Shopify and Airbnb should be enough to highlight Rails’ capability to handle higher traffic. Inadequate memory management and Ruby’s poor concurrency sprouts up issues when trying to scale quickly on the platform.

Ease of testing—Nodejs vs Ruby on Rails

To be able to work without a glitch under continuous, high load and growing market expectations, your application development project needs to go through a series of tests to ensure compliance with the UI standards, compatibility, and usability. Here’s how Node.js and Ruby on Rails stand out when compared with testing.

How easier is it to test Node.js/ applications?

Node.js offers competent testing and debugging capabilities with its rich ecosystem of third-party packages. Various automated testing tools/frameworks like Mocha, Jest, Lab and Code, Jasmine, and AVA create a sound testing ecosystem for Node.js apps. Moreover, you could use testing libraries such as Mocha, Jest, and Chai to offer a seamless, bug-free experience to your users.

How easier is it to test a Ruby on Rails app?

Testing is intrinsically woven into Ruby on Rails, which makes it simple and effective to conduct within the framework. As a developer creates models and controllers, Rails automatically starts producing skeleton test code. This leads to a considerable legwork reduction. Additionally, its emphasis on best development practices also reduces intricacies during the testing phase.

Microservices compatibility—Nodejs vs Ruby on Rails

Is Node.js compatible with Microservices architecture?

Both Node.js and Microservices build smaller parts of services and code modules. Node.js is suitable for developing scalable apps as it’s efficient at handling multiple concurrent requests. Thus, it makes an absolute combination for building enterprise-grade complex applications with higher scalability.

Is Ruby on Rails compatible with Microservices architecture?

Ruby on Rails generally leans towards monolithic architecture but that doesn’t mean it can’t be used in a microservices architecture. Airbnb, for one, initially started with a monolithic architecture, but as the system grew bigger, it got increasingly complex to manage and deploy code. It then switched to a microservices architecture and were able to deploy 3,500 microservices per week with ease after the migration. Hence, Ruby on Rails can easily take care of your microservices’ needs and deployments.

Database support—Nodejs vs Ruby on Rails

How good is the database-support for Node.js?

Node.js supports all kinds of databases like relational and NoSQL databases. However, it’s best to use a NoSQL database like MongoDB as it stores data in JSON objects, which offers more accessibility for Javascript-based backends like Node.js. 

As a matter of fact, you can use “mongoose” to manage relationships with data. The object data-modeling library is exclusively built for Node.js and MongoDB. Moreover, it boosts productivity by increasing code readability, maintaining code flexibility and providing a modelling for applications’ data among others.

How good is the database-support for Ruby on Rails?

Ruby on Rails comes configured for SQLite. However, you can easily choose from a bunch of other database management systems supported by Rails, such as MySQL, PostgreSQL, Microsoft SQL Server, Oracle, and OpenBase. Additionally, Rails also allows the use of multiple databases so that you don’t put all eggs in one basket.

Community—Nodejs vs Ruby on Rails

How big is the community around Node.js?

Node.js holds a well-supported and robust community. It is reported on Stackoverflow that 51.4% of professional developers use Node.js for frameworks, libraries, and tools. Tech giants such as Amazon, Facebook, and Google have made significant contributions to the Node.js environment, making the technology more credible. 

There are several community forums for Node.js such as,

How big is the community around Ruby on Rails?

Ruby on Rails boasts of its large, mature, and supportive community. It features everyone from beginners to subject matter experts working on the framework for more than a decade. It has more than 47.5k stars and 4000+ contributors on Github. They also have a healthy following on other platforms with 154,000 members on Reddit and more than 300,000 questions tagged on Stack Overflow. There is also a flourishing community of 14,700 RoR enthusiasts on Slack. Then there is also an active Gitter group with more than 6,000 people discussing everything around the framework. Apart from these, you can also find plenty of Discord servers with active communities following ideas around Ruby on Rails.

Hiring developers—Nodejs vs Ruby on Rails

How convenient is it to hire Node.js developers?

The large community of Node.js developers makes it easier to hire Node.js developers. The average range for hiring Node.js developers as dedicated or freelancing resources varies between $70 to $90 per hour in North America, $50 to $70 per hour in Eastern Europe. In Asian countries like India, it is from $20 to $40 per hour. With a few considerations in mind, such as the portfolio and fundamentals of Javascript, one should be able to hire the right Node.js developers for their projects.

How convenient is it to hire Ruby on Rails developers?

A large Rails community also means you get to tap into a rich talent pool to hire Ruby on Rails developers. The average hourly rate of Rails’ developers is $36, but it is subjective. It can shoot up or down depending on the scope of the project and the experience under a developer’s belt. It might not be a walk in the park to find a talented Rails developer, but you can surely find one at the right place or onboard the right tech partner.
