The complete guide to build REST APISs with Koa.Js, Sequelize And Mysql
What is Koa.js?
Koa is a new web framework designed by the team behind Express, which aims to be a smaller, more expressive, and more robust foundation for web applications and APIs. Through leveraging generators Koa allows you to ditch callbacks and greatly increase error-handling. Koa does not bundle any middleware within core, and provides an elegant suite of methods that make writing servers fast and enjoyable.
Does Koa replace Express?
Koa is more like Connect, but a lot of the Express goodies were moved to the middleware level in Koa to help form a stronger foundation. Koa makes middleware more enjoyable and less error-prone to write, for the entire stack, not just the end application code.
Typically many middleware would re-implement similar features, or even worse incorrectly implement them, when features like signed cookie secrets among others are typically application-specific, not middleware specific.
Why is not Koa Express4.0?
Koa is a pretty large departure from what people know about Express, the design is fundamentally much different, so the migration from Express 3.0 to this Express 4.0 would effectively mean rewriting the entire application, so we thought it would be more appropriate to create a new library.
Why you should learn Koa?
Promise based flow in Koa
No Callbacke hell in Koa
Better error handling through try/catch in Koa
Koa is more modular
Better user experience in Koa
Proper stream handling in Koa

I learned what I had expected based on the syllabus that was presented at the time of purchase. The course, which lasted about three hours, accurately and clearly covered all the topics listed in that syllabus.
Overall the course is good and provides a good understanding of the Koa JS framework and how we can create REST APIs with Koa JS and Relational database but there is some content in the course that needs to be updated according to the new updates both in framework and javascript language syntax and please if possible then also add a video lecture for logging in the user that might be missing. But overall the course is good to get started with Koa JS
It's really a good course. Love it.
Nice explanation
Nothing is explained. Complex functions and async / await methods are just thrown at you.
This course provided a good foundation in Koa. The challenges in Section 2 provided a good intro to coding basic CRUD routes. The remainder of the course built on this with the project that was worked on. I also appreciate the time taken to debug Koa and Sequelize.
A fast-paced course but is filled with necessary details. The instructor is very knowledgeable and follows good practices while writing code. The course can be improved by adding details like how JWT works, error handling, and how koa is different in the way it can deal with promises. However, its a very good course for intermediates
The instructor's voice sounds a bit like a cross between Kermit the Frog and Arnold Schwarzenegger, and he's a pretty excitable dude. I laughed out loud each time he was so pleasantly surprised that the code paused at the breakpoint he set with VS Code. It was as if he was discovering breakpoints for the first time every time! LOL Speaking of breakpoints, I really liked how he went in depth with how Koa works by setting breakpoints inside of the Koa source code and going over it. That's something I've never seen an instructor do before. This guy freakin' ❤️s debugging!
Not explanation at all on why or how to install the programs in the beginning

He has kept the video as required, good for the beginner level and kept the process straight forward, but in real projects, you have to write business logics also, services, repo directory files where process works in full fledge.
