Everyone love Python and its amazing frameworks. Among the set of Python frameworks, Flask and Django are the biggest talks of the town.
According to the 2018 Python Developers Survey, Flask and Django emerged as the most popular web frameworks for Python developers. Unsurprisingly, everybody is curious about how Flask & Django are different and how to choose between them.
If you too are deciding on which one to use for your next web application development project, honestly, you will hardly go wrong with either framework. Both are extensible, mature web frameworks, which offer similar functionality in handling requests and serving up documents. However, both differ in their scope of responsibility.
When the competition is amongst the two biggies of the Python development world, confusion is inevitable: Flask vs Django – which one does one go with?
To set you on the right track of web development, we list key differences of both these frameworks.
Django comes with a tagline–The web framework for perfectionists with deadlines. To achieve narrow deadlines, it is important to build web applications quickly and efficiently. And Django contributes to web development project by building clean web apps with pragmatic design in a really rapid manner. The Django official website quotes “Django was designed to help developers take applications from concept to completion as quickly as possible.”
Django’s ability to deliver quick outcomes makes it an ideal solution for building large applications.
Flask, on the other hand, comes with a slogan–Web development, one drop at a time. Moreover, the Flask official website claims it to be a “microframework for Python based on Werkzeug, Jinja 2 and good intentions.” With ‘microframework’, it means that Flask aims to be as simple as possible, yet still extensible.
Its simplicity, flexibility, and lightweight paves the way for the developers to build smaller apps in short timeframes.
Another reason why Flask delivers much better performance than Django in terms of speed is that one can write 10k lines of code with Flask for something that would take 24k lines in Django. Thus, in Flask vs Django performance battle, Flask outsmarts Django depending upon the project requirements.
Flask is everything you need and nothing you don’t.
As aforesaid, Flask is popular for bringing minimalism and simplicity to work. Flask comes with no restrictions, thus allowing a developer to build a robust application with liberty to use everything they deem fit– a vast array of external libraries and add-ons.
Flask in its documentation foreword says that “Flask won’t make many decisions for you, such as what database to use. Those decisions that it does make, such as what templating engine to use, are easy to change. Everything else is up to you, so that Flask can be everything you need and nothing you don’t.”
Django, on the flip side, is dispatched with its own set of modules and built-in features, thus shackling the liberty to experiment and control. The batteries included in Django allow developers to build a variety of web applications without using any of the third-party tools and libraries.
Thus, in the case of Django, due to its limited flexibility, developers are restricted to build an app by availing the built-in-features offered by Django.
Django was initially released close to 1.5 decades ago, in 2005. Today, it enjoys a large community of active developers who have come up with a variety of plugins, extensions, and third-party applications to cater to the rising web development needs. At present, Django has evolved into a mature platform, which leverages the benefits of a knowledgeable community.
At times writing this article, Django has 41,623 stars, 2,169 watchers, and has been forked 17,921 times.
On the other hand, Flask was released close to a decade ago, in 2010. It is a relatively young tool but still boasts a large community. Thus, it might lead to a lot of support in case you get stuck with something.
Presently, Flask has 44,169 stars and 2,263 watchers onGitHub. It’s been forked 12,404 times.
Based upon the above-mentioned statistics, no doubt, in Flask vs Django, Flask is doing better than Django in case of stars and watchers, however, both frameworks are almost neck and neck. Thus, considering the community as a parameter, you can avail the benefits of huge support for both frameworks.
Django comes with an admin system that paves the way for you to quickly create an internal tool for managing the data from your data models. It runs on ORM (Object Relational Mapper) database system and directory structure. In the case of Django, multiple projects have the same directory structure, thus, developers feel that it is an all-inclusive experience.
When looking for a web app to launch quickly, the Django Admin is considered as an easy way to provide a simple interface for managing application data. With just a few lines of code, you can come up with an app, whose look and feel of admin can be customized as per your preference.
On the other hand, Flask does not come packaged with any sort of admin interface. If you want to have an admin system or use an ORM, you’ll need to install custom modules. The extension Flask-Admin provide something that allows developers to have the same experience as with Django.
But as compared to Django, it is a little more complex to set up in case of Flask as you have to integrate it with whatever authentication scheme you implement.
EMR’s Successful Development Journey with Net Solutions
One of our clients EMR wanted to develop a bespoke decision support engine that empowers the healthcare staff to easily and quickly write, change, and test rules that facilitate patient data.
The aim was to give control to the admin of the platform to let the staff choose what criteria they want to feed into the system without any dependency on the technology team to write a code every time.
Based on the requirements finalized, the technology panel of Net Solutions decided to use Django Framework for the backend.
Flask vs Django: Which one to choose?
In a nutshell, both Flask and Django are popular open source Python web frameworks. Django is a powerful full stack framework, whereas Flask is a micro and lightweight framework. There are no set of rules as to what one should use. However, choosing a framework because you used it on your latest project or are more familiar with it is definitely not the way to go forward.
It is important to evaluate which framework is the best fit for your desired outcomes before embarking upon a new software product development project. Know your requirements and choose the framework intelligently as per your requirements.
