Node.js Vs Django: Which One To Choose?

Nodejs vs django

Web applications have become an essential part of each business today. Everybody looking to build a web application wants a great framework to work with. Node.js and django are the two well known open-source frameworks for building versatile web and mobile applications with an excellent user interface. Both are open to all and free without need of any license. They are used in various large projects and have a huge web community. Nodejs is based on Javascript and used on client-side of web applications. Whereas, Django works with Python applications within a structure of the deadline to help web developers build applications in real-time and all the more rapidly.

As both of these technologies are equally popular and versatile, it is a common issue to choose which one to use for your upcoming project. So here we’ll see a detailed comparison of Node JS and Django. Before digging to comparison, let’s have a look at basics of both the technologies.

Node.js-

NodeJS is an open-source JavaScript runtime environment written in C, C++ and Javascript. It is used for developing high-level apps using server-side Javascript. It allows developers to write complete and highly scalable web applications with JavaScript.

Django-

It is a robust open-source Python web framework used for building professional websites and web applications. Django is a high level because most of the code has been abstracted out for clean and practical code writing.

Node.js Vs django- A Comparison

1. Basics-

Node.js is a runtime environment that developers can use to execute front-end Javascript code as a backend programming language. There are third-party libraries available that you can use.  

Django is a high-level Python framework generally used for rapid development and scalability. It is open-source and works in the same way as that of other development frameworks- providing pre-built components, libraries and tools to avoid the need to code everything from scratch.

2. Architecture-

Django is a Model-Template-View based architecture. It comes with some  advantages that help to build advanced applications more rapidly. Developers can work on various modules of a single project simultaneously that makes it a rapid development platform for web apps. Component based pattern  of framework. The component based pattern of the framework offers simplicity to modification. One change in component doesn’t affect the entire application or other components.

Architecture of Node.js is different from other server-side platforms. It’s single thread event loop architecture helps to build high-end apps. This server-side runtime environment offers robustness to the applications and make it available for request processing without delays. And it is possible because of its non-blocking input/output and asynchronous request handling architecture. Handling multiple concurrent requests is simple and rapid in Node.js. It eases the application process of various requests/operations simultaneously, which results in immediate responses to the app users/ client requests. There is no context switching between threads that reduces the reloads and overall overhead time.

3. Customizability-

NodeJS offers more space for customization. The ability to create various types of applications is significantly wider since the user can build whatever they desire without any scratch, without encountering resistance from the program.

Django is a framework. It forces users to use a particular structure that identifies with MTV pattern. A user would need to adjust the structure to perform the similar task in Django as in NodeJS.

4. Performance speed-

The faster your web application, the higher the performance. There are many things that affect the web app’s performance and these are code optimization, load times, network configurations, server configurations, size and data being transformed to/from the server. 

Node.js offers great performance. JavaScript will in general be excessively slow for computation heavy applications because of the nature of its event loop, and as there’s no support for decimals it restricts its use.

Django inherits the high performance of Python. The use of multiple threads helps to increase the performance. Django provides database optimization and app caching that helps to improve the performance. 

5. Development freedom/time/cost-

Development Freedom-

We have seen that Node.js gives you more freedom as compared to Django for building web apps.

Development Time-

If you want to build an application within less time thenDjango is perfect for you. You can rapidly build apps with Django because of its many in-built libraries and methods that help you with necessary tasks and reduces repetition. Whereas, Nodejs takes more time for development as you have to start it from square one.

Development Cost-

If you take less time for development then you save a lot of money. Node.js and django both are open-source and free but django is more cost efficient.

6. Security-

Javascript is more delicate because of its language design. You can create secure apps in Javascript but because of structure it is easy to avoid issues that are in Python. If you’re building your application in Node.js, it will be susceptible to this shortcoming – you  should be careful around third-party add-ons and keep a close eye on malicious code snippets, particularly if your application requires Type A security (mobile banking, for example). 

We know that Python is a secure coding language due to its well-defined approach for task execution, extensive security-based libraries and scalability. And because of this, it is easy to create code without building in structural weakness that hackers can leverage – or creating as you scale.

7. Templates And Documentation-

Node.js is a developer-friendly tool having flexibility to design and customize templates. It is a great tool for experienced developers but for beginners it can be challenging to get things. Also it takes more time to build an app because you have to start development from scratch. For a team working on Node.js projects should ensure someone in your group is experienced in Javascript, experience working with Node.js would a great.

Django has a built-in template system. A developer with HTML knowledge can go well with this without having to understand Python. It could be useful for beginners, as the development process becomes faster because of the instant accessibility of templates.

8. Community/Dev Tools-

Node.js possesses a good developer community. If can find a lot of tools created by developers on GitHub for free. You can easily get a lot of help with your coding issues. Node.js community also looks at the new releases immediately and updates are made available fast.

Community of Django is moderately active. 

Pros And Cons Of Node.js

Pros-

  • Easier system to follow with less complicated features
  • More libraries available worldwide
  • Very active and huge community
  • Developers have an open hand to execute commands

Cons-

  • Less cost-effective, 
  • It takes more time to develop applications
  • Less secure and has security flaws
  • Low performance 
  • Less development speed
  • Non-synchronous programming makes it difficult for the programmers
  • Doesn’t work great with intensive applications, owing to the single thread system

Pros And Cons Of Django-

Pros-

  • easy to learn
  • Offers high security
  • Rapid web and app developments
  • Better performance level 

Cons

  • Allows building only single-tiered applications
  • Doesn’t work well with small apps
  • Requires more understanding of the framework

When To Choose Node.js?

It better to choose Node.js for the applications that have large number of users. There could be two conditions to use this framework. One, the processing time for each user is more. And the second one is, process that uses very less CPU cycles. When each process takes a reasonable amount of time, you wouldn’t want to waste the thread by keeping it on hold. Rather, you can use that thread to deal with requests until the previous request’s response is ready.

When To Choose Django?

You should use Django when there is security involved.  If you’re building a web app that includes handling sensitive information, Django is your best choice. Also it is better to use when you want to develop web apps that use Web API or webhooks.

Final Words-

Here you have seen comparisons of Node.js vs Django on the basis of various parameters.
