Node.js vs Django

January 24, 2021

Node.js and Django are technologies used in building versatile web and mobile applications. Both have an excellent user interface, are open-source, do not require a license to operate, and therefore they have a vast number of users. Node.js is a framework that JavaScript uses on a client-side web application, whereas Django is a Python framework used to develop fully functional websites faster with less coding.

This article will analyze these two popular technologies. The article will critically give each member the pros and cons to help the reader choose the best technology depending on the project needs.

Node.js

Node.js is a JavaScript runtime built on Chrome’s V8 JavaScript engine according to the Node.js website. V8 is an open source high performance JavaScript and Web Assembly engine. V8 is written in C++ and is used in Chrome and Node.js among others. The V8 engine is very fast and powerful which makes it among the fastest server-side solutions.

Node.js is an open-source JavaScript run time. The first version was released in 2009. Node.js is based on the following programming languages; C, C++, and JavaScript. It provides scalability and concurrency which makes it a comparable better choice in websites and web application development.

Basic features of Node.js

  • Simplicity – It is easy to learn and use, especially if you have prior knowledge of JavaScript.

  • Open-source language – It does not require installation fees and is free to use and readily available to the public.

  • Object-oriented – Object-oriented programming allows efficient data flows between components in large applications.

  • It is swift to execute code.

  • A lot of community tutorials, resources, and shared codes are available.

  • Node.js is a JavaScript runtime, a high-level and dynamic language.

Django

Django is an open-source Python web framework designed for high-speed web development. Django is simple to learn with Python knowledge.

Django has strict compliance with the rules and formalized scenarios for project implementation and it provides accuracy in coding, a straight-forward app architecture, fewer errors, and bugs in the output.

Basic features of Django

  • Simplicity – Especially with the Python language, Django is easy to learn, use, and implement.

  • Open-source language – No fees for installation and usage. It is free to access and readily available to the public.

  • High-level language – It simplifies computer syntax into a language the user can easily understand.

  • It is both object-oriented and functional – meaning it can model real-world data and focus on functions. Django allows code reusability.

  • Portable – There is no need to write different codes for different machines as it is highly portable and flexible.

  • Django has a vast collection of libraries – therefore, there is no need to write unique code for everything.

  • Django MVT (Model, View, Template) MVT is a software design pattern used by Django to handle data. In simple words, it is a data access layer. It is important to note that even though Django uses MVT, the framework controls itself. Therefore the model is only used for data presentation.

Comparison between Django and Node.js

Distinctive point Django Node.js
Programming language and primary use It is a Python based framework used by developers to build computer apps within a stipulated time frame. A framework that runs on JavaScript. Developers use it to build robust application programming interfaces (client-sided). Used also for server-side applications.
Architecture Follows the MVT model template for purposes of handling data, validating, and interaction. A runtime environment, therefore, works on an event-driven model. Runs on any operating system, maintaining a small number of requests.
Security It is more secure, because of its built-in system, prevents security breach. It requires manual operations systems to manage security risks.
Performance It has a built-in house template system; hence the execution of tasks is quicker, thereby offering better performance. It allows web professionals freedom in implementations. It may, however, take more development time.
Complexity The developer needs to follow a particular specified way of solving problems. It is less complicated as a developer has a free hand to solve problems.
Reputation It has a good and solid reputation. Its popularity is growing with time. Soon it might become a preferred framework.
Users or the community It has a reasonably active, though small community. It has quite an active community with experienced users that assist with updates and customization.
Flexibility It has strict features and does not offer flexibility. A variety of tools and features exists. It is very flexible because it is possible to build an app from step one.

Advantages and disadvantages of using Django

Advantages

  • It is comparatively easy to learn.

  • Its built-in security system ensures security risks are very low.

  • It ensures app and web development is done at a fast rate and hence cost-effective.

  • High-performance levels because of the in-built templates.

Disadvantages

  • It is not flexible because it only allows single-tiered applications. (A single-tier application is a standalone application, with all layers such as presentation, business, and data access layers in a single software package.)
  • It does not work well in small apps. Django needs a lot of coding, taking the server a lot of time to process and bandwidth.
  • It requires a detailed understanding of the framework because it does not have many publications or a vast community like that of Node.js.

Advantages and disadvantages of using Node.js

Advantages

  • It has a very active and large community, and therefore easier to access information and knowledge.

  • It has many libraries.

  • Features are not complicated; therefore, more comfortable to follow.

  • It is more flexible as developers have a free hand to execute commands.

Disadvantages

  • It does not do well with intensive applications since it is a single thread system.
  • Less cost-effective, as it requires more time for a developer to develop a project.
  • It is prone to security flaws.
  • Its performance is low. It is best on a single thread (it cannot do parallel code execution), and not as fast as multiple threads.

Conclusion

Both Node.js and Django are useful platforms used for building web-based applications. The decision whether to use Node.js or Django is determined solely by a project’s specific requirements to be undertaken by the developer.

Therefore, the developer should always focus on the project requirements before choosing whether to use Node.js or Django.

For instance, if a developer wants an app that requires intense data processing, such as social networking apps and game apps, Node.js is the best option. Node.js is a server-side run time environment in nature.

Similarly, if a developer wants full-stack apps (an app with both the front end or client-side and the back-end or server-side), then the best framework to use is Django.

Happy Coding!
