Flask is a Python framework for building lightweight and dynamic web applications. It helps speed up tedious “behind the scenes” development work, like URL mapping, and offers more control than its closest competitor, Django. If you want to learn Flask, this course provides the training and hands-on examples you need to get started quickly. Instructor Kirsten Hunter first introduces you to the basics: the Flask command line, contexts, and request and response objects for processing incoming data. She then shows how to integrate Bootstrap for quick and easy CSS styling, connect to a Postgres database, and use the WTForms library to generate HTML web forms. In chapter four, she shows how to complete the application, adding user authentication and an S3 image-processing pipeline, and deploy your new Flask app to the cloud using Heroku and Git.
