Syllabus

Welcome

In this module, we will present the highlights and benefits of mastering REST APIs with Flask and Python. You'll gain insights into the significance of this skill set for your professional growth and be encouraged to dive into the learning experience.

A Full Python Refresher

In this module, we will comprehensively review essential Python programming concepts, covering variables, data structures, control flow, functions, object-oriented programming, and more. This section will reinforce your Python knowledge and prepare you for advanced applications in API development.

Your first REST API

In this module, we will guide you through building your first REST API using Flask. You'll learn to set up the Flask app, create endpoints, and interact with the API using JSON, laying the groundwork for more complex projects.

Introduction to Docker

In this module, we will introduce Docker and demonstrate how to containerize your Flask application. You will learn to use Docker and Docker Compose to streamline development and deployment processes.

Flask-Smorest for more efficient development

In this module, we will explore the Flask-Smorest extension to improve your API development process. You'll learn to enhance data models, create new endpoints, and use Flask-Smorest for decorating responses and validating data.

Store data in a SQL database with SQLAlchemy

In this module, we will cover integrating SQLAlchemy with Flask for robust database management. You'll learn to create and manage database models, handle relationships, and perform CRUD operations efficiently.

Many-to-many relationships with SQLAlchemy

In this module, we will delve into complex data relationships using SQLAlchemy. You will learn to implement one-to-many and many-to-many relationships, optimizing your database models for real-world scenarios.

User authentication with Flask-JWT-Extended

In this module, we will explore user authentication with Flask-JWT-Extended. You will learn to integrate JWT-based authentication, create registration and login endpoints, and secure your API endpoints effectively.

Database migrations with Alembic and Flask-Migrate
