Django Vs Node.js: What does your server deserve?

Can Django Replace Node.js? Which Technology should I use for my application backend? Which of the two have a better future?

Questions like these highlight the diversity in the web development technologies. It is an unspoken truth marketing truth that no two technologies can be exactly same. You need to have something over the others that compensate for some other things that you lack. Making the discussion more specific to the theme of this article, let’s say you’re building a web-application. For front-end, the internet told you to use responsive javascript libraries like React JS. But for the backend, the google search shows different technologies in every search result. Two of the popular names that you find everyone speaking about are – Django and Node.js

One is a python based web-framework while other is more of a platform written in Javascript. One might argue that these two are fundamentally different and should not be compared, but hey fundamentals are not going to build your backend, are they?

So, that’s it then. Bring in the weighing scales, the comparison shall commence. But before that, let’s have a quick look at the two individually, for a better understanding in contrast to the other.

Django

Django is one of the marvels that python has grown into. It is a web-based framework serving as an ideal backend for RESTful web services. The ‘don’t repeat yourself’ programming structure used by python is an inherited trait in Django enabling it to efficiently use reusable and pluggable components. Having been written in Python, Django serves as a popular choice for backend development in web-applications. Following are some notable traits of the web-framework:

    Built-in Standalone server

    Event communication

    Caching

    Interface for Python’s Unit testing framework

    Internationalization

    HTML to database translation

    Database to XML/JSON representation

While on one hand, we have these remarkable characteristics of the Django Framework, on the other hand, Node.js has its own capabilities. Let’s take a look at them as well.

Node.js

Created by Ryan Dahl, Node.js was aimed at “presenting an easily scalable way to build web-applications”. Unlike Django, Node.js is not a typical web-framework. But nonetheless, it efficiently serves the purpose of the backend for any network program. Since its inception in 2009, it has become one of the preferable choices for a number of innovative startups in web-technology. Here are some of its interesting features

    Server-Side Javascript

    Non-Blocking, Asynchronous IO Model

    Single thread Design with an event loop

To better understand these features, let’s finally move on to our comparison between these to technologies.

Django Vs. Node.js: The Contrast

Complexity

If you’re a beginner and are looking for a more structured and easy-to-go-with technology, Django should be your pick. Python’s understandability is no secret to anyone. In fact, it is the readability factor that made the programming language stand out in the first place. Node.js, on the other hand, is more complex and takes more time to accumulate before you can start with building your application. As a matter of fact, most of your teachers, guides, Quora experts etc. will suggest you starting with Django to build-in a better experience of backend development in websites.

Compatibility with the Frontend (JS)

As discussed earlier, using Node.js at backend enables you to have javascript at both clients as well as the server side. Although Django’s support for RESTful APIs and strong event communication makes it fairly compatible with the frontend, having been written in the language that essentially runs the frontend gives Node.js an upper hand.

Database Control

Both Django and Node.js support SQL as well as NoSQL databases. Django has the total control over the database and doesn’t allow any extra data flow that can bypass the REST APIs. The Databases supported by Node.js include MongoDB, MySQL, and Redis while Django also supports IBM DB2, Couchbase, and Cassandra.

Processing Speed

Node.js certainly has a reputation in this field. Its launch time beats Django with almost 2 seconds which is a considerable amount of time. Thus, any application that needs a faster implementation has Node.js higher on the list.

As told earlier, Node.js and Django have their fundamental differences. But their efficiency in handling the backend services makes them both strong contenders for your website’s servers. To conclude, Node.js surely has an edge when comes to processing speed and integration with the JS frontend, Django has its upper hand in programming structure and data control. We would suggest making your choice based on your requirements and programming experience.
