Choosing a Backend Framework: Django or Express.JS

Choosing a Backend Framework: Django or  Express.JS

Django and Express.js are web development technologies used to build the backend of web applications. These technologies help speed up development when building dynamic web applications. Django is a high-level Python framework that helps in the fast development of web apps, express.js is a powerful web framework for Node.js built with JavaScript. Express.js is designed to make the process of building web apps simple.

What is Django?

Django is a Python-based open-source web development framework. Django is built such that it independently takes care of many configuration tasks which enables developers to focus mainly on app development.

One of its core features is the MVT (Model View Template) architectural paradigm. This approach aids in structuring models for storing data, views for managing the core operations and logic, and templates for presenting the user interface. This architectural design helps to beautify the codebase and make applications built in Django easy to maintain and understand.

Django emphasizes reusability and the concept of DRY (Do not Repeat Yourself), It eliminates redundant tasks which helps in fast development. Django has an administrative interface called Django Admin that is generated automatically based on the models defined. The Django Admin provides a very friendly user interface for data management, performing CRUD (Create Read Update Delete) operations, and performing administrative tasks.

Features of Django

  • MVT (Model Views Template) architectural design

This pattern of design defines a model for data storage and views for creating functions or classes that handle the logic for a certain URL or route and a template for presenting the user interface.

  • Automatic admin interface

Django generates an admin interface automatically during development and this is as a result of how you structure your database model.

  • A solidly built template system

A Django template is like a blueprint that helps organize how information is shown on a webpage. It uses special markers and simple instructions to arrange and display things. Typically utilized for generating HTML, Django templates demonstrate versatility by creating any text-based format.

Helps in building web solutions in a rapid timeIt cannot handle more than one request at once
Machine-learning friendlyIt is monolithic i.e. it can only be deployed in a whole
It is very secure and protects sites from common attacks like forgeryIt is not suitable for smaller projects

What is Express.js?

Express is a simplified and minimal Node.js framework that provides certain traits for mobile and web-based applications. Express embraces the event-driven Nodejs model, enabling asynchronous and non-blocking architecture of express applications. Express offers a simple and user-friendly interface that facilitates the creation of routes, processing of incoming requests and responses, and control over middleware functionalities.

Express enables you to choose and add more middleware functions as needed, It is a flexible framework that enables you to design and extend the functionality of your application easily.

A core feature of express.js is that it supports template engines which enables the generation of dynamic HTML pages easily (for example EJS i.e. Embedded JavaScript). Express.js provides important operations for rendering content that is dynamic.

Features of the Express.js

  • Middleware

It is an integral part of the express js web framework, with access to client requests. These are functions that make the request-response cycle in Express seamless.

  • Asynchronous and non-blocking.

This nature of express allows it to handle multiple operations concurrently without blocking them from execution. The server does not wait for a task to be completed instead it continues to process other tasks.

  • Routing.

Express.js provides a highly advanced routing system that helps maintain the state of a web page by effectively managing its URLs.

Can handle multiple requests at onceDifficulty in managing code structure, because express has no specific structure.
Flexible and simple to useCallback issues


Django is a high-level Python web framework popular for its scalability, security, and rapid development capabilities. Express is a simple JavaScript web framework suitable for building APIs and creating efficient web page routing. Express contains built-in middleware functions and also accepts custom middleware functions that execute during the request-response cycle.
