Description

Welcome to the best-selling Udemy course on REST API development! I'm Pratap, a software engineer, and I'm here to help you master web and REST API development using Python, Flask, and Docker.In this comprehensive course, we will cover everything you need to know, starting with a Python refresher that will take you from the basics to advanced features. We'll then dive into creating simple, intermediate, and advanced REST APIs, complete with authentication, database handling, and more, using Flask and popular extensions like Flask-Smorest, Flask-JWT-Extended, and Flask-SQLAlchemy.Throughout the course, we'll explore essential technologies such as Git, Postman and database, ensuring you have all the tools you need to build production-ready REST APIs. Additionally, we'll cover Docker to simplify the process of running and deploying your APIs.By the end of this course, you'll have the skills to:Create resource-based, production-ready REST APIs using Python, Flask, and popular extensions.Handle secure user registration and authentication with Flask.Efficiently store resources to a database using SQLAlchemy and Flask-SQLAlchemy.Understand the complexities of deploying Flask REST APIs.But first, let's understand what a REST API is. It's an application that accepts data from clients and returns data back. For instance, it can handle user authentication by accepting a username and password and checking their validity in the database. REST APIs are commonly used by web apps and mobile apps as clients.With the knowledge you'll gain in this course, you'll be able to develop any REST API you need for your own projects.I take great pride in offering exceptional support and feedback to every student. I'll be available to guide you and answer any questions you may have.Don't wait any longer; take the first step toward mastering REST API development. I look forward to seeing you inside the course!
