[yasr_overall_rating] Over 358 people have rated [4.8/5]

A new technology takes birth. It introduced to the general public. The aim of most newer technologies is to solve the computational problems that has often been faced by other older technologies. We will study the shortcomings that older technology faced. Because of the shortcomings that were faced by older technologies, what has led to the invention of newer programming technologies that solves computing problems. Particularly, in the field of web development and server side app development, this has taken place drastically and has led to the invention of newer and more upcoming advancements in the field of web technologies. We will be differentiating between the newer and the older technologies and will see what enhancements are done to them to solve the computation problems that existed.

In this article we are going to compare and contrast two technologies, that is NodeJS and Ruby on Rails(Nodejs vs Ruby on Rails). Both of these frameworks are developed for web application designing and programming. Let see what sets them apart as well as the similarities and differences between each of them.


Difference between Ruby On Rails and NodeJS:


NodeJS is a runtime library and an environment that is cross-platform compatible and is mainly used for creating JavaScript-based applications that run outside the browser. It is free to use as well as open-source and is utilized for developing server-side applications. NodeJS allows developers to run applications on the server-side of the web architecture.


Ruby on Rails is a server-side web application framework written using the Ruby language. The Ruby language is general purpose. Ruby on Rails helps with the rapid application development approach that is used to assist developers with a lot of built-in features and enables the developer to focus solely on the application of business logic. An open-source Rails framework is the ideal platform for developing a web application that is backed by using a database.




NodeJS provides a way that is much faster to write scripts that are light and scalable. Programmers and developers are able to write real-time applications, and at the same time provide some scope for mobile application development. Developers can easily utilize both the front end and the back end development using the same JavaScript code

There are several server-side capabilities that NodeJS is able to provide. A developer is able to listen to and can reply to HTTP requests on the computer, listening to the network traffic and at the same time access a database from the computer directly.
NodeJS uses an event-based model in order to address scalability, and allow the development using rich JavaScript libraries for JavaScript modules and this helps in simplifying the code logic.

There are plenty of frameworks that are based using NodeJS, for example, Expresses, Partial JS, etc. When the question is about building fast and scalable server-side applications, then NodeJS is the clear cut winner here. NodeJS provides JavaScript the ability to interact in real-time with I/O devices (Input/Output Devices) through the use of its APIs, it can also connect with external libraries that are written in various other languages.

Ruby On Rails


Ruby On Rails is an MVC (Model-View-Controller) based web framework that is able to provide a structure for a database, webpages as well as web services. There are various wen standards such as JSON and XML that are used for data transfer purposes and are facilitated by Rails. There are some other paradigms that are promoted and supported by Rails such as CoC (Convention Over Configuration) and DRY(Don’t Repeat Yourself) and the active record pattern.

Ruby On Rails is loaded with several features that is aimed at making the developer more productive and efficient, by providing the ability like meta-programming. Compared to any other framework that uses code generation from scratch but Rails uses meta-programming techniques. Rails also provide code generation techniques but it uses meta-programming for heavier tasks. An active record would provide saving the object to the database. Rails do not use much of the configuration techniques but prefer the use of the conventional approach.

Rails that made its mark in the early 2000s have greatly impacted the web development field through the introduction of many innovative features such as seamless database table creations, migrations to enable rapid application development, and so on. Its influence on other frameworks is pretty apparent.

Ruby on Rails also includes some tools that make common development tasks much easier for example scaffolding that can automatically create and construct some of the models and views that are required for the website. Another tool is WE Brick, which is a ruby web server that is distributed with Ruby. Using together with Rails, these tools are capable to provide a basic development environment. Rails also has an advanced level of support for JavaScript libraries as well. Initially it utilizes lightweight SOAP web services but it is later replaced by REST web services.

Head To Head Comparison of NodeJS VS RoR(Nodejs vs Ruby on Rails):



Ruby On Rails

The NodeJS framework is developed using C, C++ and JavaScript

Ruby on Rails framework is developed using Ruby.

The application developed in NodeJS are fast and scalable that run on the server-side 

Applications developed using RoR are database-backed web applications and uses meta programming

NodeJS is extremely useful when the requirement is for developing applications that are scalable as well as fast.

RoR is best suited for large scale applications.

Developers can use NodeJS applications for both on the client-side as well as the server-side

RoR is an entirely a server-side framework and does not have any client-side support

For using NodeJS, you need to install the archive file on the system

For using RoR, you need a precompiled version of Ruby via the RubyInstaller / RailsInstaller

Applications that are written using NodeJS are Highly Scalable

Applications written using RoR are less scalable compared to NodeJS applications

The page load speed is faster across the site

The page load speed is slower compared to NodeJS

There is a huge market demand for NodeJS developers

RoR is not as popular compared to NodeJS in the current scenario



Key differences between NodeJS and Ruby On Rails(Nodejs vs Ruby on Rails).


  1. Node JS is ideal for developing small size projects whereas Rails is a web application framework, well suited for database-backed web applications in MVC pattern, released in 2008.
  2. NodeJS is written with the use of JavaScript whereas Ruby on Rails is written in Ruby which is easy to learn, with understanding syntax, released under an MIT license.
  3. NodeJS is best suited for I/O non-blocking, event-based application. Rails is better suited for meta programming and database-backed modern web programming.
  4. NodeJS is derived from event-driven model architecture. Rails follows a model-view-controller pattern, the model represents the data that is handled in an Active Record.
  5. NodeJS provides capabilities to create own web servers which will handle HTTP request asynchronously. Rails uses WE Brick, Apache, NGINX, Cherokee.
  6. NodeJS has a moderately sized community that is helpful with lots of projects available with Github . Rails has a huge and strong community of developers along with a huge repository of Github.
  7. Well versed JavaScript programmer can learn NodeJS concept efficiently . Rails has a steep learning curve, recommended for seasoned programmers.
  8. NodeJS has an event-driven model and this is based on the asynchronous call. The philosophy for Rails revolves around convention over configuration principle.
  9. NodeJS is easier to install with some archive files that need to be installed on the system. The Rails installation process is longer than NodeJS.
  10. NodeJS has an interpreter that is used to interpret and execute JavaScript code. Rails has a built-in static compilation that uses Coffee Script by default.

NodeJS 12: The future of server-side JavaScript


[yasr_overall_rating] Over 487 people have rated [5/5]

JavaScript has been a boon to the industry of computing. It has proven to be the most effective tool for use in advanced web applications. With the spurge in various technological applications it is worthwhile to know that JavaScript increased in popularity. So does the advancements in JavaScript frameworks started to emerge. This has been a trend setter in providing the required functionality. It provided the much needed features to web applications.

There is no doubt that frameworks based on JavaScript are on the rise. These frameworks are capable to provide any functionality that you need in your application. It has now been much easier to incorporate and code the features and functions that web applications need. In recent years, Node JS has caught our attention, to provide the needed server side functions and features. Server applications has been a daunting task to program and code. With the introduction of node js, programming server side applications has been much easier now for programmers and coders.


Node JS is ever-growing and a game-changing technology introduced in the early 2009s. Since its inception in 2009, it has followed an upward trend. And has been a valuable platform for many developers alike. In short, NodeJS allows developers for using JavaScript to run on the server-side. And produces changing or dynamic web content. This is done before the final page is sent to the web browser running on the user’s computer. Node JS represents a JavaScript anywhere paradigm. This platform is able to unify the web application development process around a single programming language. Instead of using different programming languages for the server-side as well as the client-side scripts.


Node JS 12 upgraded

On April 23, 2019 Node JS 12 was officially launched for use with the public. JavaScript enthusiasts everywhere celebrated. And this update was not about just a regular old version. This update was going to be a big overhaul with the use of some major features and upgrades being presented to users. Let us see what has changed.


V8 JavaScript Engine upgrades

With the addition of expected performance improvements as well as tweaks that is bundled with every new version of the JavaScript V8 engine, there are some really noteworthy upgrades this time. These include the following:


  • Zero Cost Async stack traces:

This serves to enrich the error. Stack property by using asynchronous call frames without the addition of the extra runtime to the V8 Engine.


  • Faster calls with arguments mismatch:

Earlier, V8 had to handle all the function calls that had too many or too few parameters the same way, which had a performance cost to be borne. Now the engine developed is smart enough to know when it can skip this step. And this reduces the overhead caused by up to 60%


  • Faster async functions and promises:

Using async is actually two extra micro ticks faster than using promises now. If you felt that you needed a reason apart from the more synchronous- style syntax async / await provides to the developers who are not acquainted with promises


  • Quicker JavaScript parsing:

At the start of a web page, the V8 engine spends just 10% of the time parsing JavaScript. The latest JavaScript parser that has been released has improved the parsing speed by up to 30% on the desktops.



Stricter security with TLS 1.3

TLS that stands for transport layer security, is how Node handles the encrypted stream communication.

With the release of NodeJS 12, TLS gets upgraded to version 1.3. This sounds insignificant but it proves to be a major update that has numerous performance as well as security enhancements. It sounds counterintuitive at first, TLS 1.3 is actually simpler and easier to implement than TLS 1.2, making it more secure, easier to negotiate as well as quicker to negotiate between applications.
If we use TLS 1.3, the Node applications will have increased security and heightened end-user privacy while also improving the performance of requests by reducing the time required for extra handshakes for HTTPS.




The conclusion, better and improved security for everyone and it uses less latency between communicating services.

Properly configured default heap limits

Let us discuss some lower-level improvements. Up to, this point, the JavaScript heap size had defaulted to the max heap sizes set by the V8 Engine for use with the browsers, which could be manually configured otherwise. Starting with the release of NodeJS 12, the heap size will be set up depending on the available memory, and this ensured that NodeJS does not try to use more memory than what is available and terminate the process when its memory is exhausted


We can say goodbye to out of memory errors- at least some time when we process a large amount of data. The old –max-old-space-size flag will still be available will be available to a different limit if it is needed. But this feature will, in turn, reduce the need for setting the flag.



The default HTTP parser is now llhttp

Unknown to many, the current http_parser library that has been used in Node has been extremely difficult to be maintained and to be improved upon. That is the reason why llhttp was born. This project is a port of the http_parser to TypeScript which is then run through llparse to generate the C or bitcode output.


It turns out that all HTTP is way faster than http_parser by about 156%. It has been written using fewer lines of code.  All the performance optimizations have been generated automatically as compared to http_parser’s hand-optimized code


In NodeJS 12, the development team has decided to switch the default parser to llhttp for the first time and put it to the test. We can all hope that it continues to perform well when lots of different applications with lots of different needs are using it out.



Diagnostic reports on demand

When we switch to the conversation about debugging, there is a newer experimental feature in NodeJS 12 that allows the users to generate a report on demand or when certain trigger events occur.
This kind of real-time reporting can easily help diagnose and correct the problems in production, slow performance, including crashes memory leaks, unexpected errors, high CPU usage, etc. – the kind of stuff usually takes a lot of time and hours if not days to debug, diagnose and fix.



Integrated heap dumps

Another feature in this release for Node JS is around heaps. This is sure to speed up the debugging process, is integrated heap dumps, which ships with NodeJS 12, already built-in.
Now there’s no need to install new modules for the investigation of memory issues – just tell Node what kind of JSON-formatted diagnostic summary you want to use in the command line or an API call and you can be able to parse through all of the info.



Native modules get easier in Node.js

Stepping back up from the muff that aide low-level improvements, there’s some cool stuff also coming for developers as well as the module makers within the Node ecosystem.
Developing as well as building the native modules for Node continues to improve, with changes that now has included better support for native modules when used in combination with worker threads, as well as the version 4 release of the N-API, this has made it easier to configure your own threads for native asynchronous functions.
Summed up, this means that creators and maintainers of Node-specific modules have almost as easy a time maintaining these modules as pure JavaScript module creators. The increased complexity that resulted from maintainers needing to rebuild the distributed binaries for each Node.js version. They wanted their modules to support is now largely abstracted away courtesy of the N-API.


Startup time improvements

Node.js 11 had reduced the startup time of the worker threads by almost 60% by using built-in code cache support.
NodeJS 12 has built upon this idea in order to generate the code cache for built-in libraries in advance directly at build time, this allows the main thread to use the code cache for starting up the initial load of any built-in library written in JavaScript.
The result is that there is a 30% speed-up in startup time for the main thread. And your apps will load for users faster than ever before.

The Node JS platform now being 10 years old.  It is single-threaded and most widely used as well as adopted. Yes, it is not as widely adopted and used as some programming languages. Node JS is able to be used for both the client-side scripts as well as the server-side programming.


Node JS is able to bring some exciting improvements like ECMAScript Support, better application security and quicker startup times.

Node js vs python


[yasr_overall_rating] Over 347 people have rated [5/5]



In this article we are going to compare as well as contrast two major technologies, that is NodeJS and Python. Let’s us jump right into the basics:



1) What is NodeJS and What is Python?


Before we start discussing the basics of these technologies and platforms, we need to clarify what exactly these are that we are comparing.

Python is a computer programming language. Node JS is not. The language used for NodeJS is JavaScript. Node Js is a runtime environment for JavaScript.

The main key difference between Python and NodeJS means that when you do coding inside of NodeJS you are using the same basic language (JavaScript) for both the frontend and the backend.


Lets us deep dive into the breakdown of these technologies.


2) The advantages provided by Python to developers is as follows


Python is very friendly to junior developers and inexperienced developers.


Python is a very beginner-friendly language. This is why it is much likely to be the most popular introductory language in US universities. Major mistakes made by junior developers in some frameworks are easily forgivable, and they are less of a hindrance moving forward in development.


On the other hand, inexperienced developers tend to get slowed down by making mistakes in development. These mistakes are common to people who do not fully understand some of the more advanced concepts and the inner workings of JavaScript.
This phenomenon can be easily attributed to the way JavaScript has advanced over the years. Concepts such as object-oriented programming have been receiving meaningful traction only after plenty of much less elegant code snippets and tutorials have been spread online.


Most of the Python frameworks do not require a very high skill level from the developer’s point of view.
A very good example of this is the Django framework, that has a mature ecosystem and allows you to write quality code swiftly.


Python is more versatile as well as universal
Python can be used for desktop app development, and all the credit goes to electronJS, the main use case that is favorable to node js is the web. The applications of Python have known to go far beyond the web.

Python is the main candidate to become the next level programming language for data science. This is a great asset to system administrators because it allows them to write small one-off scripts and on top of that it provides large system admin tools such as Ansible


A good example that has used Python is Dropbox, one of the most common desktop apps written in Python.


Python is simpler as well as easy to use, better documented and better covered.
This is proven to give Python an edge over NodeJS, even after both technologies are admittedly fast to write in.
NodeJS is a JavaScript implementation, this is a language with a long history and a predominantly a front end tool. Therefore solutions that involve, NodeJS can be easily found online. But these may be inadequate for backend use and they rely on inaccessible interfaces


This use-case cannot be overstated, because each JavaScript framework or runtime environment tends to have a slight deviation on how it was implemented using JavaScript.

This situation has been improved over the years. But it is still a long way off from Python where CPython being a single implementation that is used in a vast majority of Python projects.


3) The advantages of Node JS are as follows

Node JS developers are more flexible

Since we have the same language that is used for both the front end as well as the back end, you need to be a JavaScript developer to use NodeJS. This functionality can come handy when you most needed it. The fact remains that when you have a solid understanding of the project and have the right people to build it, you cannot go wrong with JavaScript and NodeJS.


The development environment of NodeJS is less opinionated

Numerous NodeJS packages are simple, single-purpose libraries and micro frameworks that force the developers to make conscious decisions on what to use them for and when.


This makes NodeJS much more demanding. It requires a high level of advancement on the developer’s front than what it takes to generate code in Python on top of Django using built-in solutions for ORM, cache abstraction, and so on.


With NodeJS you can use JavaScript for coding any functionality

NodeJS allows you to code both the backend as well as frontend using JavaScript. This implies that you do not need to know different technologies and that shows that your developers do not need to learn a different implementation of the same programming paradigms.


At the stage of assembling your development team, you do not know how many, Python or JavaScript developers you will be required, your needs will also differ in sprints, depending on your goals.


Using the same language for the entire project removes the risks from the equation. You can also share a part of the code with the front and the back ends. This is a huge benefit to not having to do the same thing twice.


The NodeJS community is very large and JavaScript is one of the most dynamic and fastest-growing programming languages out there


JavaScript has been growing at an exponential rate. There are more than 500 packages for JavaScript being introduced every day. Python has no longer the advantage of numerous libraries that it once in time used to have. JavaScript has caught up with NodeJS in this aspect.

4) The problem with NodeJS and JavaScript

JavaScript has been developing super fast now. But this was not the case earlier.
In the beginning, the language was constructed haphazardly, and it has been struggling with issues caused with its older versions as well as the compatibility issues that bring with it.


JavaScripts recent rise in popularity has also brought another major downside to it.
So many developers have turned to the language in such a short period of time that it has been pretty difficult to keep up with the latest updates in the languages


The swift and rapidly grown happening to the language also brings another problem with it. This problem is that there is no proper and detailed documentation for these libraries that have been coming up for Node JS. This results in the poor quality of programs for Node JS programs.


Sadly this is nothing new for JavaScript as it has been very typical. If history has taught us anything it is that Python is much more reliable.



5) Main aspects to consider


Here are 3 main aspects that shed light on the different aspect of the story, this will help you to make an important decision:


Trending Technologies:

Python has been a major player in Machine Learning applications in the field of data science and it provides tested libraries for ML
It is far easier to find ML experts who are well versed in Python than JavaScript
MicroPython-a lighter and smaller version of Python can be run with much less resources and less power thus making it a perfect fit for IoT devices.


On the other hand, NodeJS is much more comfortable to be used in the Internet of Things (IoT)
When you compare the most popular libraries for Python and JavaScript


Speed and Performance:

One major drawback of Node JS is its inability to multitask., It cannot do many things at the same time unless you write very well code for it. Both Python and NodeJS pretend to do a lot of stuff at once, but Python applications tend to use a much simpler and traditional multiprocessing model approach instead of a more advanced asynchronous paradigm.



When written correctly, your software will send information to the Operating system that it needs to perform a certain task and move on, while the system works on that. But if you did not code the application efficiently, the app will wait for the system to complete the task and does not do anything in the meantime.


Team Composition:

The truth is that Python is well suited for some projects and JavaScript for others. Lets not that building software is a fluid process. The most important thing is team composition. If you have good python developers, then use python. Or if you have good JavaScript developers then use JavaScript.

At the end of the day, it depends on what features do you want to implement in your project and how you want your overall application to behave. You can and you should choose the technology that best fits your requirements and fulfills all your objects, it does not matter whether this is achieved using Python or NodeJS JavaScript for that matter.
