I've been working as a developer for a while, but I haven't properly read official documentation before. It was really great because it felt like you were breaking down and explaining the NextJS documentation, and I was able to learn how to approach reading official documentation in the future. The course content itself wasn't about learning extremely in-depth, but rather it was great content that helps you become a developer who can understand NextJS's operating principles and use it effectively. However, it seems like this paid course includes some lectures that were uploaded to YouTube, so it would be great if you could include reference playlists or links in the announcements or course introduction! There are some topics mentioned throughout that were explained in the YouTube content!

This is such a great lecture. When the lecture first came out, I emailed about the resolution issue and received a response that you had requested improvements from Inflearn, but it's a bit disappointing that the maximum resolution still remains at 720p (though it doesn't interfere with viewing).

Hello, I enjoyed the lecture very much. Even though I took the course after reading the Next.js official documentation first, the early part of the lecture where each topic was clearly addressed with the flow of problem → background → solution helped me organize my understanding well. I was particularly impressed by the explanation approach that unfolded from the perspective that development is ultimately about problem-solving, and the parts where you explained based on actual code along with background knowledge were very helpful. I think this lecture can serve as a good guide for those who are just about to introduce Next.js or those who are considering introducing SSR after feeling the limitations of CSR. However, there were a few disappointing aspects. In the early routing implementation part, when you started explaining with code written by generative AI, it was confusing from my perspective of expecting actual internal implementation code, and I had doubts about the direction of the lecture. (Of course, my misunderstanding was cleared up when you later explained based on actual code.) Also, curriculum title compositions like path automation or template.tsx animation that you implemented directly might feel like official Next.js features, which could cause some confusion, so it would be better if you separated them into separate sessions or clarified the explanations. And personally, I was disappointed by the lack of explanation about cache strategies that have become important with App Router. There were also some parts in the lecture flow where mentioning later content early on made it feel like prerequisite knowledge was needed. Nevertheless, overall it was a well-organized lecture that is helpful for practical work. Thank you.

When I transitioned from React to Next.js, I had some vague ideas about what parts needed to be handled on the server and how they operated, but this lecture gave me hints about that. My skills are still lacking, so I couldn't fully understand the entire lecture, but it was a great help in terms of being able to grasp the development direction using Next.js and the direction for my studies. I believe that if I build up my skills further and revisit this lecture, I'll be able to gain much more than I did now. So long!
