Why we prefer Django to Node JS - 2021?

Why we prefer Django to Node JS - 2021?

Nisha Sridhar
django

Django is a very robust open-source Python web framework. It is a very high level as most of the low-level stuff has been abstracted out. It is known for having a “batteries included” philosophy, therefore ready to be used out-of-the-box. Very rightly, Django called itself as a framework for “perfectionists with a deadline.”

node js

NodeJS is a cross-platform runtime environment built on Google’s V8 engine, used to build efficient and fast web apps. It is based on JavaScript and can run both on the client-side as well as server-side.

The Comparison

Architecture

Django is Model-Template-View based architecture. The web framework comes with several advantages that help build apps faster, better, and advanced.

Node JS architecture is distinct among other server-side platforms; its single-thread event loop architecture helps build high-end applications. It runs on an operating system, maintaining a small stack of requests.

Though Node JS’s architecture makes it light-weight as compared to Django, but that may be essential for only micro-services where the processor footprint is critical. Django, on the other hand, provides for a framework which has authentication, swagger APIs and ORM inbuilt which makes it heavier, but more manageable.

Security

Django is more secured and comes with a built-in system, preventing any security deficiency. Django helps to avoid much common security falls like SQL injection, cross-site scripting, cross-site request forgery, etc.

NodeJS is not inherently as secured as Django and requires manual operations in the system to manage security flaws. This step is important as the default session cookie names used by the framework could expose your application to the attacks.

For relatively small projects, it would make sense to choose Django as there is not much of a security audit done in the industry. Moreover, the ORM layer prevents any SQL mistakes, which could wipe out entire tables.

Scalability & Performance

Django is thoroughly scalable considering the fact that the application caching is much simpler and there are many tools available to do this. Although Django is scalable, there can be issues with small scale applications. Django inherits Python’s high performance. The use of multiple threads increases performance. Django framework is more efficient and offers fast speed. And so, it is more cost-effective.

Node JS applications can be scaled by using the cluster module to clone different instances of the application’s workload using a load balancer. But due to Node JS working with single threads, it performs poorly in CPU intensive conditions. Node JS framework is easy to learn but consumes more operating time. Thus, it is a less cost-effective option. Doesn’t work great with intensive applications, owing to the single thread system.

Ease of Development

With Django, a developer can take his idea to execution very very quickly. Django makes it easier to build better Web apps more quickly and with less code. The Object Relational Mapping is how Django lets you write queries from simple to complex code first, again instead of having to write complicated, error prone, insecure pure SQL in your back-end controllers. Seamless collaboration with relational databases. Some very good points in Django which make development easier:

· No complex Database Setup in development phase                                         According to Django’s “batteries included” philosophy , you do not need to create a DB, add tables, write SQL queries , to even get started with your application. It comes by default with a SQLITE DB , which comes very handy during development.

· Admin Panel to quickly add test data:                                                                         As soon as you define a model in Django, a relevant table, along with an admin panel for managing CRUD operations in provided, which is very , very handy for development.

· Use the vast library of Python in your app                                                          You can use any library out of the rich Python PIP libraries with your Django app, which is a big plus, especially for data-modelling projects, and artificial intelligence.

· Django Rest Framework                                                                                            Django REST Framework (DRF) is a popular library choice when it comes to creating REST APIs with Django. With minimal effort and time, you can start creating APIs that support authentication, authorization, pagination, sorting, etc. Once we start creating production-level APIs, we must do a lot of customization that are highly supported by DRF.

To build a complete web application in Node JS might seem steep because you’ll need to understand Node’s architecture, asynchronous programming, SQL,  and native methods. Non-synchronous programming makes it difficult for the programmers to grasp at once.

Learning Curve

To work with Django, the methods need to be understood as well as the features that come out-of-the-box. A full understanding of the framework’s MTV (Model Template View) architecture needs to be understood as well.

To work with Node JS, you need an understanding of asynchronous programming, Node’s native method and architecture.

While learning Node JS and Django requires knowledge of their base languages, Node JS introduces some complex concepts that makes it a bit difficult for beginners when compared to Django. Plus, to create any real world application, one has to have a good knowledge of SQL too, which is otherwise taken care in Django’s ORM layer.

External plugins like Sequelize add ORM to Node JS, but it largely remains unexplored, as we have seen major applications write thousands of lines of SQL, which not only creates scope of error, but also hampers readability of code.

Pluggable databases

If you want to want to start with a postgres  and switch to a MariaDB ( MySQL) database later, Django would be a great framework. You just need to use a different config block in your settings.py file, run your migrations, and populate your db. No code level model changes required. No code level queries/CRUD changes required.

Whereas Node JS requires a lot of changes in order to implement the same which include changing your queries to match the new DB style and your insert statements as well.

Admin Panel Feature

A web-based administrative backend is a standard feature of modern websites. The administrative interface, or admin for short, allows trusted site administrators to create, edit and publish content, manage site users, and perform other administrative tasks.

Django comes with a built-in admin interface. With Django’s admin you can authenticate users, display and handle forms, and validate input; all automatically. Django also provides a convenient interface to manage model data. Everyone can benefit from an instant GUI to crud their database objects as soon as they're written though. It makes prototyping a joy.

The above figure shows how a Model is created.

By registering the model in the admin file, you get an interface to perform CRUD operations on the database.

Node JS doesn’t provide an admin panel, a separate panel should be created to manage the CRUD operations.

Use Cases

Uber, Twitter, eBay, Netflix, Duckduckgo, PayPal, LinkedIn, Trello, PayPal, Mozilla, GoDaddy are some big names using Node JS as their backend technology.

Pinterest, Instagram, Eventbrite, Sentry, Zapier, Dropbox, Spotify, YouTube are also some big names using Django as their backend technology.

Inbuilt Templating Support

Django has a built-in templates system. Anyone with HTML understanding can go along well with this without having to understand python programming. It could be helpful for beginners, as the development process becomes faster due to the ready-made availability of templates.

Node JS is a developer-friendly tool. With the flexibility to design and customize templates, it has become a preferred tool for experienced developers. But the downside is that the beginners find it challenging to get things right at first. Another challenge is that it takes more time to build an app since you have to start building an app from scratch. It will also be essential to invest your time searching for implementation modules and a separate time for their testing.

Rest Framework

Django REST framework is a powerful and flexible toolkit for building Web APIs. DRF takes care of the heavy lifting of transforming our database models into a RESTful API. There are two main steps to this process: first a serializer is used to transform the data into JSON so it can be sent over the internet, then a View is used to define what data is sent.

·  Simple to use: Create, view and revoke API keys via the admin site, or use built-in helpers to create API keys programmatically.

·  As secure as possible: API keys are treated with the same level of care than user passwords. They are hashed using the default password hasher before being stored in the database, and only visible at creation.

·  Customizable: Satisfy specific business requirements by building your own customized API key models, permission classes and admin panels.

Conclusion

Django has its own cons such as it is monolithic, not great for small scale applications but it is a great choice when you are considering using a relational database, a lot of external libraries, have security as a top priority on your list and need to build the application quickly.
