![]() Install virtualenv in your system using the command pip3 install virtualenv. That will help us avoid conflicts in dependencies across projects. We will use virtualenv to manage a separate virtual environment for this project. Please do not skip these steps unless you know how to set up virtual environments and to run Flask.Ĭreate a virtual environment so that you do not mess up your existing python libraries and functions on your system. To start working with the project, we have to do some basic set up so that we can proceed smoothly. If not, you can Google and find some good tutorials for doing so with your concerned operating system. I assume that you have installed Python 3 and have it working. It’s effortless to code even for the beginners. You can create a flask application in a single file as described below. You can read the documentation for in-depth coverage. It has answers to most of the questions, and I have to admit, it is one of the best-documented open source projects when it comes to details and clarity of writing. The best guide for flask is the flask documentation itself. Flask is more flexible compared to other Python web frameworks like Django, but the onus is on you to get things working correctly as there are not many rules or “Flask way” of doing things. (Log in, Sign up, Password change, etc.). This can be helpful, as we shall see in the next part of the tutorial when we work on user management. It means it is more extensible and gives you the freedom to choose and decide the custom extensions and plugins to use. The microframework in case of flask does not mean it can only do little or provides less functionality. We will talk about Jinja in detail in later parts of the series. It renders the web pages for the server with any specified custom content given to it by the webserver. Jinja 2: It’s a template rendering engine. Werkzeug: It is one of the most advanced WSGI ( Web Server Gateway Interface) modules that contain various tools and utilities that facilitate web application development. To put it in simple words, it’s a python-based framework to build web applications.īut what is this Werkzeug ( How to Pronounce?) and Jinja? According to flask’s website Flask is a microframework for Python based on Werkzeug, Jinja 2 and good intentions.
