Roadmap to Becoming a Flask Developer

Now let’s have a look at the steps to becoming a Flask web developer.

1. Learn the Fundamentals of Python

The first and the most obvious step is to have some basic proficiency in Python. Since the Flask framework is written in Python, the backend of your web application will be completely dependent on it. 

It is highly recommended to have some rudimentary knowledge of Python programming language. If you are new to coding and want a basic idea of Python, check out this article.

2. Understand the Basics of Web Development

Flask is mainly used for web application development. So before you start learning Flask, you need to have an idea of what a web application is and how to develop, deploy and maintain one.

You don’t have to be a pro at it. If you have a basic understanding of using HTML in the front end and accessing HTTP variables in the back end, you’re pretty much good to start.

3. Learn the Fundamentals of Flask Framework

If you know the basics of Python and a basic understanding of web development, it’s time to learn the Flask framework.

To become a pro at something, you need to have a strong foundation. Start by learning the basics clearly, apply your knowledge to simple concepts, and slowly make your way into big projects.

Here are a few steps you can follow to become good at Flask:

  • Open your favorite Python IDE, build a simple webpage and start running it on a local server using Flask. To brush up on basics, take a look at this article on Introduction to Flask Web Development.
  • Try experimenting with the design. Try using multiple pages with the help of URL routing. Take it further by creating a website with multiple pages to test your URL routing skills.
  • Once you can connect multiple pages, try assigning some value to your website. Use forms to get data from users or try making it more interactive. This increases your skills over back-end development.
  • To turn your code into a real-time application, connect it to databases to store information. You don’t need to be a pro at database management. If you know basic SQL commands, that works well too.
  • Now try and combine all the things you have learned to construct a working app that runs in real-time. Try creating multiple projects using the different concepts. This will boost the quality of your portfolio.
  • To start your series of Flask projects, here is a step-by-step guide for a small project of creating a To-do-list app using Flask.
  • Create a GitHub account and upload all your projects on it. Document your projects in a readable format. You can also create some open-source material to help novice developers.
  • It’s always great to have a portfolio of projects so that you can show your skills to employers or recruiters.

You can learn Python and Flask using their official documentation. If you are not comfortable learning with the documentation, do courses on Flask development. 

Free courses are available on YouTube. Platforms like Udemy provides a lot of quality courses. Doing courses on websites like Coursera or Udemy can get you certifications which can convey to employers that your flask knowledge is legitimate.

4. Start Monetizing Your Skills

Once you think you can solve problems using your Flask web development skills, start applying for jobs. 

You can also try to get experience by taking up freelancing. It enhances your coding skills, experience, and other soft skills. For more ideas on monetizing your web development skills, check out our article on How to Make Money as a Web Developer.

Try to apply for internships in companies that might give you a Flask project. If you have the right skills and interest in Flask development, there is a high chance that the company may consider you for internships and provide you with projects related to your area of interest. 

An internship can be a valuable experience for you in terms of working on a real-time application of Flask. This can also be added to your resume and can come in handy when you apply for a Flask developer job.

Applications of Flask

If you’re still feeling skeptical about Flask being a career choice, don’t worry. Here are some of the companies that have Flask in their tech stack:
