Hopefully that gives you a bit of an idea of what is Flask and to avoid theoretical information overflow, I will move on to more practical aspects of the subject. Here is how routes definition may look like in your application code:Īs I already mentioned Jinja2 syntax allows you to use variables and conditions/flow control statements inside of HTML code creating dynamic web applications. With help of those components you can leverage concepts of routes (defined URLs which your app can recognize and reply to with HTML) and use Jinja2 web templating engine for the Python programming language (which allows you to write HTML templates with variables and control flow statements).

As with any technology choice final decision is yours and it should be largely defined by your existing expertise and specific task(s) at hands.Īrchitecturally Flask includes two big parts: a web server and a templating engine which simplify creation of web applications.

Some people would say that Flask is your best option for prototyping, whereas you may want to investigate other options/frameworks for large scale production projects. But “expandable” part, does translate into the fact that you need to write more code for things which are not included in favor of “lightweight” (but there are lots of extensions which can make your life easier). “Microframework”, in this case, supposed to be understood as “expandable and lightweight”, rather than “restricted and limited”. What is Flask? Flask is a microframework written in Python. In this post we will look into how to install Flask and run flask applications. This blog post is a brief introduction to Flask (micro)framework and its installation on Ubuntu server. I’m currently doing some online courses on web development, learning a bit about Flask before moving on to Django.
