Node.js Vs Django: Which One is Better For Web Development?

Nodejs Vs Django

The most popular websites and web applications of today have a very good User Interface so that the Customer Experience becomes really good and more people are attracted to the website or application. The part of the website or web application that is visible to the User is known as the Front End and it is very important for any website or web application to have an engaging front end. However, it can be said that to have a great Front End, it is imperative that the Back End of the website or web application needs to be really good.

The back End of any website or web application is that part of the application which is not visible and accessible to the user. Even though not visible directly to the user, a lot of the major functionalities of the Web applications are handled using the back end. It usually consists of servers, databases, API’s and many more parts which power the front-end components of an application to work seamlessly.

There are a number of Back End Technologies that have been developed to date: Rails, Django, Laravel, Node.js, etc. These technologies provide a lot of features to the application like testing, debugging, and database management tools.

These back-end technologies ensure that the productivity of the developers is increased (as they do not have to reinvent the wheel while coming up with solutions to various problems) and that the development process is seamless. Two of the most popular Back End technologies that have been used to develop hundreds of applications back end are Node.js and Django. Both of these technologies are very much in demand in today’s tech world and in this article, we are going to deep dive and take a look at what these two Technologies are and what are the major differences between Django and Node.js.

Nodejs and Django

Introduction to Node.js

Node (also known as Node.js) is one of the most popular open source, back-end JavaScript runtime environments of today’s time. It can be used across a lot of platforms for the execution of JavaScript code outside a web browser.  Node.js allows developers to utilize JavaScript to the fullest by using command line tools (CLIs). It also allows developers to write scripts on the back end or server side, for instance, running scripts on the back end to develop web page content that is dynamic, before sending the page to the web browser of the user, etcetera. Node.js also allows developers to create REST APIs which aids in the faster and seamless development of web applications .Node.js represents a “JavaScript everywhere” paradigm and unifies web application development around one single programming language (that is Javascript) rather than multiple languages for both client-side and server-side scripts. For the execution of JavaScript code on the backend or server side, virtual machines like Google’s V8  run it on the servers. Hence, Node.js acts like a wrapper around virtual machines like them. 

A lot of developers all around the world want to learn node.js and node.js frameworks because it makes the task of building back-end API services extremely simple and convenient. Node.js has a lot of in-built modules which provide a lot of cool features via easily understood asynchronous (a way of parallel programming in which, a unit of work runs separately from the main application thread and notifies the calling thread of its completion, failure, or progress) Application Programming Interfaces (APIs ).

Key Features of Node.js

A budding developer should definitely learn node.js because it possesses the following features:- 

  1. Node.js supports the extremely popular “JavaScript” language and can be used for building extremely scalable and fast applications.
  2. Node.js is very useful for making prototypes of web applications and agile software development.
  3. Due to its clean and consistent codebase and a large ecosystem of libraries, Node has found its usage in some of the huge corporate companies including GoDaddy, Amazon Web Services, IBM, LinkedIn, Microsoft, etcetera. So, Node.js can be extremely useful for clearing technical rounds  (find node.js interview questions here) and a well-versed Node.js developer is most likely to secure a job at any technology company.
  4. Node.js can run on a lot of operating systems, for instance, Linux, Windows, or macOS.
  5. It can also be used for the backend development of any web application, which means that the entire development process can be done using only JavaScript. The information and expertise required for full stack developers have emerged, and a budding programmer of today can commence launching his or her own app faster using Node.js.

Introduction to Django

Django

Django is a free and open-source Python based web framework that follows the MVT (Model View Template) Architectural pattern. It was developed and is maintained by the Django Software Foundation (DSF), an American independent nonprofit organization. The Django web framework helps in supplying ready-to-implement solutions for the backend of applications.

It eases the creation of complex, database-driven websites by emphasizing reusability and “pluggability” of components, less code, low coupling, rapid development, and the principle of don’t repeat yourself (DRY). The Django framework can also provide an optional administrative create, read, update and delete interface which can be generated dynamically through introspection and configured through admin models. Some of the famous companies using the Django Framework are Instagram, Mozilla, Nextdoor, etc.

Key Features of Django

Now that we know a little about what the Django framework is, let us take a look at some of its key features: 

  1. Django can be claimed to be one of the most popular Python frameworks of all time and is primarily designed to facilitate quick development.
  2. Django mainly focuses on high-level processes and abstracts the low-level processes.
  3. All the projects made using Django can consist of particular or multiple internal applications.
  4. Django supports the extremely popular “Python” language and can be used for building extremely scalable and fast applications.
  5. Django can be used to create scalable web applications with good performance and speed.

Now that we have a clear understanding of what Node.js and Django are, let us take a look at the major differences between the two and see who wins in the competition: Node.js vs Django:

ParameterDjangoNodejs
Initial ReleaseThe Django web framework was first released in the year – 2005.Node.js was first released in the year – 2009. 
Developed byDjango was developed by the Django Software Foundation (DSF), an American independent nonprofit organization.Node.js was previously governed by the Node.js Foundation. The Node.js Foundation has now merged with the JS Foundation to form the OpenJS Foundation which maintains The Node.js distributed development project.
Key AspectDjango is mostly a web development framework.Node.js is mostly a runtime environment for Javascript 
Language on which the framework is developed onDjango is a Python-based web framework.Node.js has been developed on top of JavaScript, C, and C++.
