Difference Between Django and Node.js - GeeksforGeeks

22 Feb, 2022
In this article, we will describe Django & Node.js so that we may establish a foundation on which we may describe their differences.
Django is an open-source web framework written in Python that allows you to create web applications. Django was created in 2003 by Adrian Holovaty and Simon Willison while working at the Lawrence Journal-World newspaper company, and it was later released for public use in 2005. Django development is now supported by an independent foundation, the Django Software Foundation. Django is self-described as “The web framework for perfectionists with deadlines”. It encourages rapid development and clean, pragmatic design, so you can focus on writing your app without needing to reinvent the wheel. Django is one of the top Python web frameworks, and consistently takes the lead as the most recommended framework to learn when creating web applications with Python. 
Django takes care of user authentication, content administration, site maps, RSS feeds, and many more tasks — right out of the box. Django takes security seriously and helps developers avoid many common security mistakes, such as SQL injection, cross-site scripting, cross-site request forgery and clickjacking. Its user authentication system provides a secure way to manage user accounts and passwords. Some of the busiest sites on the planet use Django’s ability to quickly and flexibly scale to meet the heaviest traffic demands. Companies, organizations and governments have used Django to build all sorts of things — from content management systems to social networks to scientific computing platforms.
Django follows the MVT (Model-View-Template) software design pattern, a variation of the MVC (Model-View-Controller) pattern. The difference is that Django takes ownership of the Controller aspect of the pattern, which leaves the template for a developer to design and implement. 
Django implements the Model, which defines the basic layer of the web application, and is implemented through the use of a database, such as PostgreSQL. The View implements the logic that is applied when a user navigates to a URL within the website or application. The Template system allows developers to generate dynamic HTML by containing static HTML as well as Python syntax in templates that control how static and dynamic content will be rendered on a page.
Features of Django:
Versatile: Django can build almost any type of website. It can also work with any client-side framework and can deliver content in any format such as HTML, JSON, XML, etc. Some sites which can be built using Django are wikis, social networks, new sites, etc.
Security: Since the Django framework is made for making web development easy, it has been engineered in such a way that it automatically does the right things to protect the website. For instance, in the Django framework instead of putting a password in cookies, the hashed password is stored in it so that it can’t be fetched easily by hackers.
Scalability: Django web nodes have no stored state, they scale horizontally – just fire up more of them when you need them. Being able to do this is the essence of good scalability. Instagram and Disqus are two Django-based products.
Portability: All the codes of the Django framework are written in Python, which runs on many platforms, such as Linux, Windows, and Mac OS.
Example: A Django Template which demonstrates looping through different pages in a Django project
Python3
{% for page in pages %}{# Do something... #}{% endfor %}
 
Node.js is an open-source and cross-platform runtime environment for executing JavaScript code outside a browser. It was developed by Ryan Dahl in 2009. It was composed in C, C++, and JavaScript. In other words, Node.js could be a JavaScript stage that capacities like a web server that permits engineers to compose total and exceedingly versatile web applications utilizing JavaScript. Node.js was built on the Google V8 JavaScript motor. There are thousands of open-source libraries to back Node.js You need to remember that NodeJS is not a framework and it’s not a programming language. Most people are confused and understand it’s a framework or a programming language. We often use Node.js for building back-end services like APIs like Web App or Mobile App. It’s used in production by large companies such as Paypal, Uber, Netflix, Walmart, and so on. 
Features of NodeJS:
Easy to get started and can be used for prototyping and agile development.
Provides fast and highly scalable services.
Easy for a JavaScript programmer to build back-end services using Node.js, as it uses javascript.
Source code cleaner and consistent.
Huge open source library.
It has asynchronous or Non-blocking nature.
Example: This example create a Hello World web-based application using Node.js. Create a firstprogram.js file containing the following code.
Javascript
// Require http headervar http = require('http');    // Create serverhttp.createServer(function (req, res) {       // HTTP Status: 200 : OK    // Content Type: text/html    res.writeHead(200, {'Content-Type': 'text/html'});           // Send the response body as "Hello World!"     res.end('Hello World!');   }).listen(8080);
