I would like to start the course review by saying thank you for sharing the latest next knowledge. First of all, the lecture source code uploaded to GitHub causes various inconveniences in practicing. Once you run the downloaded source code ch0, there are many elements that cause confusion in learning, from the very basic problem of not being able to see the text at all when using Chrome in dark mode, to the case where it is called 3-2 source but you have to refer to the source of 3-1. I thought that it would have been easier to learn if you could open it in order so that you could follow the learning progress without wasting time going back and forth to find the source. The code is divided by section, but from section 3, the source code needs to be further subdivided. I think it would have been much easier to learn if the code that records the intermediate process was shared rather than the complete code. Of course, you may say that you can do it by coding directly, but if you recommend copy and paste as a way to study in the beginning, but there is no process in the shared source code and only the result, I think that this is enough to cause confusion in learning. And one more thing, please mention the file name and function name rather than this here and there. From the perspective of the student, they are not as familiar with the source code as you are. So they waste a lot of time checking the file name one by one. In conclusion, it was a lecture that left a regret that although it was easy to acquire the latest Next concepts through video lectures, there was a lot of time wasted to get the same result by only watching the video lectures. I am leaving a review because I hope it will be helpful for future knowledge sharing and I think it will be helpful for other students to know in advance before starting their studies. Addition 1: 3-2 should include all the contents of 3-1, but the contents of the .env files were different, so the mock API call did not work, so the missing parts from each source had to be combined to run the code without errors. There were a few more, but I can't remember them all, so it's hard to tell you all. Starting from ch4, when you run the server and connect, there's a problem with signing up. After applying the backend server, if you sign up, you won't be automatically logged in, and the login modal won't log you in either. I didn't sign up to learn while fixing the error-ridden code, but there are errors in all the sources for each ch, so I'm just wasting my time. Additional 2: The login failure issue in section 4 was a problem with running radis. In the main lecture, they only told you to install radis, and they didn't even mention running radis before running the nest server. In particular, in the case of Mac, they just showed the homepage and skipped over it. Since it's a front-end lecture, I think there will be quite a few students who lack back-end knowledge, so I think you should have explained the part about configuring the development environment more thoroughly. I think this content is often mentioned on the QA board, so if there are many similar questions, it would be good to check if there are any missing parts in the main lecture. I hope students don't waste their precious time wandering around with the same content.
