What is Flask?

Python-based Flask is a microweb framework. Due to the fact that it doesn't require any special tools or libraries, it is referred to as a microframework. It is devoid of any components that pre-existing third-party libraries already provide common functionalities, such as a database abstraction layer, form validation, or other components.

In 2004, a programmer by the name of Armin Ronacher developed Flask as a prank. Despite this, the open-source community accepted it with open arms. As a result, it developed into a well-known open-source project with a sizable fanbase that it still has today.


Advantages and disadvantages of Flask

Advantages of Flask

  • Scalable - As Flask is a microframework, you can use it to swiftly expand a tech project like a web app because size counts. If you want to make an app that starts small but has the ability to grow quickly and in areas you haven't fully worked out, this is the ideal choice. Because to its simplicity of use and absence of dependencies, it can continue to run without interruption even as it scales up and up.
  • Flexible - One of Flask's primary advantages and a key component. According to The Zen of Python, simplicity is better than complexity since it can be reorganized and moved about more readily. This makes it simple for your project to change direction and guarantees that the structure won't collapse when a part is changed. Flask's minimalist design and ability to build more compact web projects make it more adaptable than Django itself.
  • Easy to negotiate - Similar to Django, being mobile is crucial for allowing web developers to concentrate on just coding quickly without being bogged down. Because the microframework is inherently easy to comprehend and allows web developers more control over their code and the possibilities, they can save time and effort by adopting it.
  • Lightweight - When we use this term to describe a tool's or framework's design, we mean that there aren't many components that need to be assembled and disassembled, and it doesn't need a lot of extensions to function. With this layout, web designers have some degree of control. Moreover, Flask supports modular programming, allowing for the split of its functionality into numerous exchangeable modules. Each module acts as a stand-alone building block that is capable of performing a certain function. Together, this shows that each of the structure's component parts may be moved, adjusted, and tested independently.
  • Documentation - Users of Flask will discover a sizable amount of examples and suggestions organized in a structured manner, adhering to the creator's own belief that "good documentation design makes you actually produce documentation." As a result, developers are encouraged to adopt the framework because it makes it simple for them to learn about all of its features.


Disadvantages of Flask

  • Not a lot of tools - The lightweight design of this microframework inevitably has some drawbacks. The main one is that Flask doesn't have as many tools as Django does. Developers will therefore need to manually add extensions like libraries. Also, if you add a lot of extensions, the app may start to run slowly from the volume of requests.
  • Difficult to get familiar with a larger Flask app - Because the creation of a web app using Flask might involve many different detours and turns, a web developer joining the project in the middle of development may find it challenging to understand how it has been planned. Coders may experience problems as a result of the modular design of the microframework we previously described because they will need to become familiar with each individual component.
  • Maintenance costs - Because Flask can interact with so many different technologies, a company adopting it frequently has to pay extra for the support of those technologies. For instance, if a technology interacting with your Flask app gets outmoded or is discontinued, the business will need to search for a replacement that is compatible. The potential maintenance and deployment costs rise as the program becomes more complex.


Important Features of Flask

  • Development server and debugger
  • Integrated support for unit testing
  • RESTful request dispatching
  • Supports Jinja templating
  • Support for secure cookies
  • WSGI 1.0 compliant
  • Unicode-based
  • Extensive documentation
  • Compatible with Google App Engine
  • Robust extensions available


Final Thoughts

Flask is where you should start if you want to learn Python web programming. In addition to the comprehensive and easy-to-understand Flask documentation, there are tutorials available for every ability level that can help you get started, increase your skills, and develop useful applications.

The documentation also covers Flask's design process and the thinking behind the team's decisions. Now that you are aware of this, you may choose whether or not you wish to take part in the Flask project explicitly or any other Pocoo project in general.
