I really liked the previous TypeScript lecture and this lecture. I always watched only the ddd lectures of spring, but it was a new world to listen to the lecture of the node version. I was constantly worrying about how to structure the service, and you solved many problems. I highly recommend it. Please increase the resolution. I can't see the code well. ㅠㅠ And I only use vscode, so could you add a simple method of using intellij to the lecture?
