Backend Development, the Kotlin Way
Hi, I’m Piotr Wolak, and I will walk you through practical Kotlin backend development, step by step.
Spring for GraphQL with Kotlin Coroutines
In this tutorial, we will learn how to expose GraphQL APIs using Spring for GraphQL and Kotlin coroutines.
A Quick Guide to htmx in Kotlin
In this tutorial, we will learn the most important htmx concepts and create a basic application with Kotlin HTML DSL and Tailwind CSS.
Auto-reload in Ktor
In this, short quide, I will show you how to enable the development mode and auto-reload feature in Ktor application.
Tired of overcomplicated fullstack setups?
Let me show you how easy it is to build full-stack apps with Ktor and HTMX — for free.
This is the best course on the web about KTor. It has a lot of good information with practical and concise content. I am super excited about the new content in the future.
I am learning Kotlin and needed to implement security in an API, your course helped me a lot and I have learned a little more about Kotlin along the way, Thank you very much for your contribution.
HIGH QUALITY TUTORIAL!!!! This is the one that you were looking for. Codersee explains how to properly create the retrofit client, takes you through simple methods slowly building up the complexity and in the end adds interceptors for logging and mutating the request. I have been looking for a good tutorial on retrofit on the web for a couple of last days. THIS ONE IS GREAT! Polish engineers never disappoint. In one hour I got more done than in a day with other tutorials. GOOD JOB! 😀
I found out about this course through the developer community, and it has been an excellent experience. The course is well-structured, covering everything from the basics of Ktor to advanced implementations with databases, WebSockets, and authentication. I particularly enjoyed the practical approach, where each module builds on the previous one, allowing me to apply my knowledge immediately. Unlike other courses, this one provides real-world challenges and hands-on projects, making learning more engaging and effective.
This course fully describes the process of implementing authentication and authorization feature using RESTful API and Spring Security which is why I highly recommend it if you're new to Kotlin and/or RESTful apps development. I'm really surprised it is 100% free to take. Overall I'd say it's a great piece of educational material to improve your skill stack.
I bought his Ktor-Backend Course last week. It's soo amazing. There is no comparable product at this level out there. Fact ... and it's super cheap. The early bird version has only cost me 29 euros. Others would charge 299 euros for such a course. Props to u Codersee. Keep up the good work!
"Learn Kotlin through practice" is a good way to learn and revise Kotlin. Not only would it be especially beneficial for newbies, but even an experienced developer might find it useful because of these features: it has lots of examples, it has large number of tests and exercises, it covers both basic and advanced concepts. Highly recommended.
Thank you for sharing your knowledge in this course. I enjoyed finding professional-level content that I can apply in real life. I am ready to start my first backend in "Ktor" right now.
I liked the course very much! Among other materials on the internet, this one was straightforward and way less confusing in many aspects. Recommend!
In Piotr's "Learn Kotlin Through Practice", he teaches and builds examples from a great foundation. He's especially good with his Kotlin function examples. And, if you have an object oriented background in, say, Java, he does a great job in illustrating the differences. When you get to his Unit Testing section, that's where Piotr really shines. He gives full and complete examples, including functions and data classes.
A great course! It has opened up a horizon of opportunities beyond the ordinary. What I really like: The structure and content of the course, which allows me to advance at my own pace, as each lesson is short and allows me to delve deeper and experiment. The challenges are wonderful, and I truly feel like I've learned the concepts covered. There are many explicit and implicit tips about tools and coding. The professor, Piotr, generates a vibe that makes every lesson enjoyable. Everything works. The course is spectacular. And as Piotr says, when he's coding a function: "Beautiful!"
I was looking for a good tutorial about spring boot with kotlin and i found this tutorial. It is one of the cleanest tutorial following best practices.
I start doing spring boot and kotlin. Honestly there is no ressources showing the path as your tutoriels do. Every time I'm searching for some ressources on the internet, your site is already referenced and when it come to youtube, your channel is the only one proposing that courses. And you touch a very great point by doing JWT tutorials because I was struggling with that. The course is very comprehensive and well structured. Thanks for this amazing work. Your tutorials helps me a lot.
Good quality tutorial, teaching the good practices. I would recommend it to anyone willing to start with latest Spring Boot and wanting to do it well.
I recently completed this course on JWT authentication in Kotlin, and it exceeded my expectations! The instructor did an excellent job explaining JWT concepts, token creation, validation, and security best practices in a clear and practical way. Thank you very much!
