A REST API is an application that accepts data from clients and returns data back. For example, a REST API could accept text data from the client, such as a username and password, and return whether that is a valid user in the database. The cover takes you through a Python refresher that will take you from the very basics to some of the most advanced features of Python. Further, you will move on to create resource-based, production-ready REST APIs using Python, Flask, and popular Flask extensions. Learn to handle secure user registration and authentication with Flask. Learn to use SQLAlchemy and Flask-SQLAlchemy to easily and efficiently store resources in a database; understand the complex intricacies of deployments of Flask REST APIs. You will also investigate essential technologies such as Git and database migrations with Alembic. Together, we will develop a REST API that not only allows clients to authenticate but also store and retrieve any data you want from a database. Learning this will help you develop any REST API that you need for your own projects! By the end of the course, you will have understood and developed your skills in web and REST API development with Python, Flask, and Docker.
