Here we create a virtual environment and install dependencies as demonstrated below. Preparing Development Environmentīefore building our first simple web app, we need to prepare the environment for our development. In this post, I am going to demonstrate how to use FAB to build a simple web app step by step. Widely used web applications, such as Apache Airflow, Apache Superset, and so on, are developed using FAB. It includes detailed security, auto CRUD generation for your models, Google charts, and much more. It is easy to use, rapid in application development. As an (extended) web app development framework, FAB is open source, and initiated and maintained by Daniel Vaz Gaspar. While one can build everything from scratch directly based on Flask and Jinja2, extensions built on top of Flask are available to make web app development more efficient and effective.įlask AppBuilder (F.A.B) is one of them. Flask is a very popular (micro) framework for web application development.
