Spring is hard! Conquering the basics of backend/server development with Kotlin and Ktor (Developing a coffee ordering system)
Spring is hard! Conquering the basics of backend/server development with Kotlin and Ktor (Developing a coffee ordering system)
Thank you! I enjoyed watching it. The way you write code & develop feels similar to mine, so it was nice to see..! - Appropriate layer separation - Core logic handled by services - Domain handles parts that need object responsibility - Writing SQL first before creating ORM persistence layer queries, etc. - Method placement, etc. I've been mainly using Line's JDSL recently, but I'm planning to apply Exposed to future side projects. I created one repo and kept updating to main without creating branches, so it's about 60 commits now! Now let me mention some areas that feel a bit lacking.. 1. Looking at the repo, it seems like you started in May 2024..! As of October 2025, Ktor is now up to version 3.3.0, so there are some changes..! Still, I think it would be great if you could add updates continuing from the last lecture about once every 3-6 months! 2. Besides global request/response interceptors, if there's common logic for specific operations, is there a way to apply it like Spring AOP? 3. If actually deployed to AWS, how much less CPU/RAM resources would it use compared to Spring..!? 4. Usually with JPA, we use Querydsl to handle dynamic queries safely, but I was disappointed that there wasn't coverage of how to handle dynamic queries in Exposed (only PathVariable, not dynamic queries created with QueryString) 5. For unit tests, slice tests, and e2e tests in Ktor, what's commonly used? I wrote about various things because I have many hopes..😊 Still, the course was really enjoyable to watch! I think I'll also consider Java with Spring+JPA+Querydsl(openfeign) and Kotlin with Ktor+Exposed going forward. Thank you.

It was great to be able to understand Ktor. Thank you. It seems like it will be very helpful for basic server development. I will study the advanced version further.

I highly recommend ktor to anyone who is learning ktor for the first time or needs to introduce it to their company, as it provides easy instructions on everything needed to create a web application (application development, build, and deployment)!!!

I was disappointed that there weren't many KTOR lectures, but this is very helpful.

I only used to play with Android, but I wanted to try out server mode, and it was great that KTOR told me things I was curious about!

I haven't completed it yet, but I feel good about it, so I'm leaving a review! Pros: He's gentle, unlike other instructors Although it's a ktor lecture, it contains more content about backend development than I thought, but he explains it calmly, so I'm following along well. I personally think that Kotlin concepts like lambda and receiver functions will be helpful for project development later, so I liked the part where he gave the lecture in the beginning, And while I was making a coffee menu service, the instructor's experience? I liked it because it felt like a good tip here and there. -- Cons: It seems a little slow when I listen at 1x speed, but it was just right for me when I listened at 1.5x speed Since the subtitles aren't included in the video by default, I'm watching it with auto-generation, but sometimes I get confused because there are parts that don't match.
