Course Description
Welcome to the top-rated 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!

Hi Pratar, I really like your explaination much more than the original course creator, Jose Salvatierre. I bought your course expecting to see your approach to this shop/product API to compare with Jose's, not a complete identical solution... I saw your reply to a similar review. Eventhough we all learn by emulating, teaching material should be original creation, which especially it's important when you are making an earning from those videos and Jose didn't publish his content for free neither... I will definitively purchase your future courses, because you are a very effective teacher.

I am very happy with this course! You will need some background knowledge in programming to grasp concepts (I learned back-end using C# and am relatively new to Python) but Pratap does a great job detailing step-by-step how to create a back-end, web API with Python from scratch which is what I needed. Very grateful for this course! Only thing that would have been nice is a way to learn how to do pagination in API form and how to use query parameters but otherwise I was able to make a fully functioning back-end template for my project following this course.

where is all of the source code. i assume i have done something wrong because the swagger-ui will not display my endpoints or the schemas. too many times, he says, "lets make it easy i'll just paste the code". content was informative. it would be nice to understand why use flask_smorest vs other options

Course is good if you are familiar with these topics or you have seen such thing earlier. But if you are completely beginner to REST API world then you may find it difficult to cope with it. As I believe before we directly jump to the library and start writing the code we should first tell the problem and then tell the other way to solve that problem and then at the end we should come up with the library or framework that we are going to use stating that how this will solve our problem. Thats what I believe is the appropriate way of teaching. I am not saying this course is not good. OfCourse Pratap has put his efforts and made this course affordable. and even I got my questions answered on time. But if you are someone who are okay to get something from video and then go to internet and do your own research as well then you can take this course. As you may find some of the libraries are old and you may not find the exact code that he is showing in the video. Hope this helps. But no doubt it's a good started course. I am comfortable that I can start and make API. and oncourse there is lots of lots to learn. And on top of that instructor's availability to answer your queries would never be a problem.(atleast in my case it wasn't :) ) Note: I am specifically talking about section starting from sec-3 till sec-8. As I am also very new to rest api world :) Happy Coding
