Personally, this was the most fun lecture among the front-end lectures I took at Inflearn... 👍🏻 The lectures are based on nextjs, typesecript, and tailwind, and I think the class was made more fun by using various libraries. It would be better if you listen with a basic understanding of next, typescript, and react, but even if you don't have detailed knowledge, the lectures are taught step by step, so I think anyone can easily and enjoyably listen to the lecture. If you install next latest, next15 version will be installed, but if you install version 14 and follow along, the lecture will be easier. When I installed version 15, there were errors during the deployment process even though the code was the same as the instructor's. (The parts where I got errors were params and cookie. They said that the API was made asynchronous when it was changed to version 15. Of course, I could have done it strangely and it could have been an error. I'm crying ㅠㅠㅠㅠㅠㅠㅋㅋㅋㅋ ) The url below is about the changes starting from next15.
