Why Flask is a Good Web Framework?

The concept of web development has grown in popularity as the number of websites and web apps has skyrocketed. Python is commonly used to create server-side web applications and works seamlessly with frameworks that make web development easier. Flask is one such framework. It is a compact, lightweight, and flexible Python web framework that allows developers to create real-world applications with a single Python file. If you are planning to become an Flask Developer, it would be advisable to learn more about tricks and strategies by taking courses such as Flask Training in Chennai.

What is Flask?

Flask is a Python-based web development framework created by Armin Ronacher as part of the popular Pocoo projects. The framework is built on the Werkzeug WSGI toolkit and the Jinja2 template engine from the Pocoo project.

Let’s go over these terms in more detail below.

WSGI

Web Server Gateway Interface is a Python web application development standard. It defines the interface between a Python-based web application and a web server.

Werkzeug

Werkzeug is a comprehensive set of Python libraries for developing WSGI-compatible web applications. Werzeug, in other terms, provides a set of utilities for developing Python programs that interface with WSGI servers.

Jinja2

Jinja2 is a Python templating language based on the Django template. Jinja2 can be used to generate XML, HTML, or other markup langauge formats that are returned to the user via an HTTP request.

Why Flask is a Good Web Framework?

Flask is an excellent framework for developing web applications. This Flask instructional part will explain why Flask is so popular among web app frameworks.

Scalability

Flask is a highly scalable framework that can accommodate any web project concept. As a result, even if you start small, Flask can handle more requests as you build up. Furthermore, Flask modularizes the source as it evolves over time, making it notable for its scalability.

Shallow learning curve

Flask outperforms all other Python frameworks in terms of learning curve, making it extremely popular among developers. Anyone with a solid understanding of Python can learn Flask in a matter of weeks.

Support for testing

Most web application frameworks do not include a testing option, which is an important part of the software development lifecycle. Flask, on the other hand, includes an in-built unit testing tool that allows developers to test their apps before they go live. Flask’s additional capabilities, such as an restful request dispatching, in-built development server, and a fast debugger, make it a popular choice.

Better control over codes

Flask’s codebase is small, and developers have complete control over it. The framework allows developers to select the components they want for a specific application and gives them considerable control over the framework’s different extensions. 

Allows experimentation

Most significantly, Flask allows developers to adapt to and experiment with evolving technologies, as well as leverage agile development processes to their full potential. Furthermore, Flask assists developers in improving and modifying their products through easy integration and support systems.
