Python has carved a niche for itself by offering some of the greatest advantages to the web developers and software engineers. It is a programming language that is easy to use and does not require much coding due to available libraries and API-powered services. Furthermore, there are a number of tools and features that makes it one of the most preferred software programming languages especially in web applications, data science and machine learning applications. All you need to do is to hire Python developers and they will cater to your needs, no matter how complex they are.
When it comes to python web development, programmers have the liberty to use a wide range of web frameworks that can help them to design and develop robust and efficient web applications. There are full-stack python web frameworks and lightweight, extensible frameworks that can be used to create web applications.
Generally, when it comes to lengthy and complex web application development, programmers use full-stack web frameworks such as Django. On the other hand, to develop simple, web applications, they use lightweight, extensible web frameworks such as Flask.
Django Flask comparison is one of the most debated and discussed topics among python developers on online forums. Even for aspirant Python developers, it is very crucial to know when to use Django and when to use Flask. With such clear understanding about these two most popular web frameworks, programmers can save their time and efforts and can come up with robust, effective and end-to-end web applications that can serve the core purpose.
In this blog, we will discuss the difference between Flask and Django in details for Python developers and enthusiasts.
Django Python web framework is a full-featured Model View Controller framework that has its own built-in-user model which can create RESTful API alone without the need of any third-party APIs. The model, furthermore, facilitates API authorization and authentication too. One of the most important advantages of the Django framework is that programmers don't have to put more efforts to create even complex web applications. It facilitates reusability of components and rapid, fast development with less coding. Even most complicated, data-driven web applications can be developed with ease and comfort when it comes to the Django web framework.
Flask is a micro-framework that is lightweight and extensible. The concept on which Flask works is doing one thing with utmost sincerity and dedication. It offers a wide range of extensions to the programmers as it does not have ORM. One major drawback of the Flask framework is that it cannot create RESTful APIs alone like Django, it has a basic set of tools for different types of authorization. Furthermore, Flask also does not have libraries and tools to help developers. In fact, it also does not have a database abstraction layer or third-party libraries or form validation methods. It has a wide range of extensions that can be used to develop web applications.
Flask vs. Django comparison
Now, let’s do a comprehensive Flask vs. Django comparison while keeping in mind some of the most crucial parameters.
Web framework types
Django is developed on the concept of batteries included methodology and it helps programmers to complete all the basic web development tasks including database schema migration, URL routing and user authentication. It is one of the most used python web frameworks by programmers due to ease and comfort associated with it.
Flask is a simple in nature, a lightweight and extensible python web framework that lacks many built-in features you can find in Django. However, for simple and uncomplicated web applications, programmers prefer flask over Django as it is easy to build simple web applications.
Django has a built-in, ready-to-use admin interface that makes things easier for developers. They can easily manage common project administration tasks. Moreover, if you want to customize your admin module based on the project requirements, it is possible with Django. The Django admin interface is highly functional and feature-rich and makes it smooth sailing for users to manage and administer projects. It is one of the best qualities of the Django web framework that is preferred by developers.
Both- Flask and Django have template engines that make things easy for developers when it comes to developing dynamic web applications while saving their time and efforts. Flask is based on Jinja2 template engine that was inspired by Django's own template system. Jinja2 helps developers to develop dynamic web applications by facilitating them of writing templates in an expressive language. Django template system helps developers to identify the user-facing layer of the web application easily. Also, you can write templates using Django template language to develop a custom user interface.
Built-in Bootstrapping tool
Flask does not have any built-in Bootstrapping tool while Django has one called Django-Admin. With the help of this bootstrapping tool, you can start developing a web application without any external input. Also, it facilitates users to create multiple applications within a single project for better administration and control.
The main reason why developers prefer Django over Flask is the way Django offers project administration facilities. Flask asks developers to create a separate application for each project, whereas Django allows programmers to create multiple applications within a single project. It means better administration and control of each application in a meaningful and accurate manner. Programmers can write individual applications effectively and add functionality to the application by integrating them into the project.
With Django, you can use a prolific ORM system by working with popular databases such as MySQL, Oracle and SQLite. In addition to that, with Django, the ORM system allows programmers to perform different database operations without writing SQL queries. Flask does not have a built-in ORM system. However, programmers can work through SQLAlchemy to perform various database operations. The SQLAlchemy functions as a SQL toolkit and ORM system.
One thing where Flask outplays Django is flexibility. Django has batteries that help programmers to build web applications without using any third-party APIs, tools and libraries. However, the main issue here is the inability to change the modules provided by Django. The Flask outshines Django here as it is a micro but extensible web framework that allows developers to use third-party libraries and tools to develop web applications.
Usage and Use cases
Both- Django and Flask are popular python web frameworks that are largely used by Python developers to build web applications. However, if we have to believe the statistics, developers prefer Django over Flask due to various robust features available with Django. However, when it comes to small and simple web applications, Flask has an upper hand over Django.
You have learned the differences between Flask and Django, two popular python web frameworks. Which one to prefer among the two frameworks depends on the type of project and its complexity. If the project is complex and large in size, Django should be preferred. On the other hand, for small and simple web applications, you can go for the Flask web framework. The programmers should decide which framework to use for a particular project.
