What is Flask?

Flask is a micro web development framework that is developed with Python. It is referred to as a micro web-framework because it does not come with special tools or libraries as seen in a full-fledged framework. 

To Fully Understand What Flask is, we first need to find out what a web application framework is.

A Web Application Framework or A Web Framework is a collection of modules and libraries that allows a web application developer to develop software applications without having to bother about low-level details such as thread management, Protocols, servers, etc.

Flask has no abstraction layer for databases, no form validation, or any other built-in components or implementation where already-existing third-party libraries provide regular functions. However, Flask offers support for extensions that can add full application features as if they were implemented by default in Flask itself.

Modules and Extensions are provided in flask for object-relational mappers, handling of file upload, form validation, and various open authentication technologies together with several common framework related tools. Flask extensions are updated far more often than the core Flask program.

Flask was developed by Armin Ronacher, who leads an international group of Python enthusiasts who go by the name Pocco. Flask is based on the Werkzeug WSGI toolkit and on the Jinja2 templating engine. Both the WSGI toolkit and Jinja2 are projects that are developed and managed by Pocco.

The Web Server Gateway Interface (WSGI) has been chosen as a standard for web application development with Python. WSGI is a specification that is used for a universal interface within the web server and web applications that are on it.

Jinja2 is one of the most popular templating engines for web development with python. A web templating system connects a template with a certain data source to render dynamic web pages. Flask aims at keeping the core of an application simple yet modular and extensible.

Features Of Flask

There are lots of features of the flask micro web framework and some of them are:

1. Flask comes with a development server and debugger for testing and debugging your application during development.

2. Flask comes with inbuilt support for unit testing.

3. Flask comes with a RESTful request dispatching

4. Flask makes use of Jinja2 for templating which has more features and flexibility when compared to other frameworks.

5. Flask offers support for secure cookies (client-side sessions).

6. The Flask micro web framework is 100% compliant with WSGI 1.0.

7. Flask is a Unicode-based micro web framework.

8. Flask comes with extensive documentation and community.

9. Flask is compatible with the Google App Engine.

10. Flask extensions are made available to add more features as desired.

Benefits Of The Flask Micro Web Framework

There are many benefits and advantages of learning about the flask micro web framework and some of them are:

1. Flask has a very flexible layout for projects.

2. Flask is both extensible and flexible

3. Flask is very easy to learn, basic knowledge of python will take you very far in Flask.

4. Flask comes with a great documentation website and a large developer community to help you out with any challenges that you encounter with Flask development.

5. Flask is highly scalable.

6. Since there are very few abstractions between Flask and the database, request, cache, etc, the application performance is very fast from the beginning.

Advantages of Studying Flask

As a web or software developer, there are next to infinite reasons why you would want to study the flask python micro web framework, some of the reasons are based on the few components of Flask that are listed below.

Flask has advanced in-built support for unit testing of your code, An in-built web application development server and a very fast debugger that points you to the section and line in your file that may be causing the error, A restful dispatching of web requests, Its Unicode based structure, Its Support for browser cookies.

Flask also has an advanced templating language known as jinja2 that helps to ease your web development task by allowing you to include/ embed python syntax into your HTML code to allow for the injecting of dynamic content into your application template.

Flask gives you total control over your project, how you want it to look, unlike other web frameworks, you can define your application as you want.

Flask modular and lightweight is another reason why Flask is loved by many because you can easily upgrade it into a full-fledged web framework with the addition of some third party extension, this makes your web-apps to be easily scalable. 

With Flask micro web framework you can make use of your favorite Object Relational Mapper to Design your database schema and to query the database which makes its learning curve easier.

When compared to most web frameworks, Flask applications are very easy to deploy to a production server. Now, this is a very useful feature because it helps to shorten the development time and the time to push your application to production.

There are lots of job opportunities that are out there for a Certified Flask Developer below are a few of them:

  • You can work as a Web Application Developer for a software company.
  • You can work as an Application Developer for organizations.
  • You can work as a Multimedia Programmer.
  • You can work as a Multimedia Specialist.
  • You can work as a User Interface/ User Experience developer.
  • You can work as a Web Content Manager for software companies.
  • You can work as a Web Developer commanding high pay.
  • You can work as an API Developer, whose task is to develop Restful API services to be consumed by other services and technologies such as mobile applications or frontend web frameworks eg, React, Angular, Vue.
