In our article, we will be using – perhaps – the most common (and sensible) of choices in terms of extensions and libraries (i.e. Our Choices In This ArticleĪs we have just been over in the previous section, Flask-way of doing things involves using the tools you are most comfortable with. It is not a strictly “conventional” framework and relies partially on configuration files, which frankly make many things easier when it comes to getting started and keeping things in check. For this purpose, it comes with its own extensions index and a good amount of tools already exist to handle pretty much everything from log-ins to logging.
Instead, Flask allows the developers to use the tools they desire and are familiar with.
#FLASK BLUEPRINT HOW TO#
In this DigitalOcean article, we are going to see how to create an application directory, and structure it to work with re-usable components created with Flask’s blueprints. The minimalist web application development framework Flask, has its own - blueprints. Although certain frameworks are shipped with tools (for scaffolding) to automate – and ease – the task (and the headaches), almost all solutions rely on packaging / modularizing applications as the codebase gets distributed across related files and folders. There are many methods and conventions for structuring Python web applications. Step 5: Set Up The Application in “app/init.py”.Step 4: Define Application Controllers (Views).Step 2: Define The Module Data Model(s).Working With Modules And Blueprints (Components).Installing Flask And Application Dependencies.Flask: The Minimalist Application Development Framework.

You can reuse Blueprint applications however you cannot run a blueprint on its own as it has to be registered on your main application. They make administration of very large Flask applications easier and as such can be used to scale Flask applications. Blueprints are a powerful concept in Flask application development that allow for flask applications to be more modular and be able to follow multiple patterns.
