Django Vs Flask: Which one do you require?

If you are pondering whether you need Django or Flask for your project, here is all you will find out. Both the frameworks are written using Python; hence you will experience that this programming language is the ultimate need. According to the Python Developers Survey, two popular Python frameworks include Django and Flask. In order to help you make a wise decision between the two frameworks, you will have to find out the basic differences between Django vs Flask.

What is Django?

Django was built in the fall of 2003. It is an open-source and free Python development framework, following a Model Template View (MTV) pattern. Django was built to simplify the website development process. Moreover, it emphasizes on the components such as less coding and rapid development. In addition to this, it was preferred by numerous frameworks such as Plone and Zope. However, it has inspired several other frameworks, including CherryPy, Bottle, Pyramid, and Web2py.

What is Flask?

Flask is a microframework having an astounding beginning. The creator of Flask, Armin Ronacher, had already written two solutions known as Werkzeug (server framework) and Jinja2 (template library). Armin thought he needed to compile the two solutions and put them in a zip file. So he called this new Framework, Flask. When a developer installs this framework, the installation program spontaneously unzips the file and operates the two solutions simultaneously. It was very unexpected, but Flask received a positive response.

Main differences between Flask & Django 

In order to develop a better understanding of the two frameworks, let us dig into some more facts. You will soon be able to decide which framework is most suitable for your project.

Django offers its own Django ORM (object-relational mapping). I use data models, whereas Flask does not have any kind of data model at all. Data models let the developers connect database tables using classes in a programming language. Hence they are able to work with models in a similar way as database situations. Flask has no data model since it has a different philosophy as compared to the Django philosophy. Django rolls everything together, whereas Flask is more modular.

Another main difference between Django and Flask is that Django offers a comprehensive featured Model View Controller framework. Its purpose is to make the process simple for website development. It depends less on reusable components, coding, and rapid development. However, Flask is a microframework that is based on the concept of better performance. It does not provide an ORM. In addition to this, it comes with an essential and basic set of tools only for web development.

Comparison of Django vs Flask frameworks

Let us compare Django vs Flask based on some of the features to explore which framework can work best for your project.

Django vs Flask: Performance

Performance is a significant indicator for studying the system functionality of Django vs Flask. If such kind of framework shows good performance, it will provide a speedy, scalable, and secure app. On the other hand, weak performance leads to scaling down and architectural problems.

While keeping in view Django and Flask performance both deliver good results, and high-traffic websites use it. Hence it is a prodigious indicator of their efficiency.

Django vs Flask: Packages

Flask does not provide any restrictions, which means that developers can apply exactly what they need using the external libraries. Therefore it makes Flask very flexible and extensible.

Whereas, Django has a huge number of built-in packages. There are more than 4,046 Django packages. It means that you are more likely to find a package built according to your application requirements using less effort.

Django vs Flask: Community

While considering Python Django vs Flask comparison, it is worth mentioning that Django has an enormous and active developer community. Therefore, if you have any queries, you can always ask them on different web portals and forums, including Stack Overflow. Thus, there are many chances that you will find all your answers. In addition to this, it is not even difficult to get a Django job.

On the other hand, the Flask community is not even as big as Django. Consequently, it might not be a good option if you are dealing with difficult coding or are confused about getting answers. Moreover, it will take some time for you to find answers to all your queries.

Django vs Flask: Security

Django provides you with several options to protect your application from several issues such as:

  • Cross-site request forgery (CSRF): 

CSRF outbreaks make sure there is no malicious user for executing actions by utilizing credentials of other users. Django has a built-in defense against most kinds of CSRF attacks.

  • Cross-site scripting (XSS):

 XSS attacks allow an attacker to insert client-side scripts in the browsers. Therefore Django templates defend your project from maximum XSS attacks.

  • SQL injection:

SQL injection is an outbreak where malicious users are capable enough to execute arbitrary SQL code on the database. Django’s querysets are usually protected from an SQL injection since inquiries are built using parameterization.

The Flask-Security library delivers similar mechanisms as Django in order to prevent data leaks and other types of web attacks.

Which one to select?

You can select Django if you are short on time and have a limited budget. In addition, Django is an ideal solution for MVPs, mHealth apps, e-commerce platforms, and government sites.

However, you can opt for Flask if you have a small or mid-sized project that consists of distinctive requirements or any custom constituents. Hence, Flask is particularly apt for prototyping.
