I will help you gain the deep understanding and unique perspective needed in the AI era, from technical interviews to practical system design, by diving into the source code together. Grow from a developer who has simply "used" Next.js into an expert who "understands" why it is used that way.

I've been working on several projects using Next.js so far, but I always wondered if my understanding of the framework I was using was insufficient. However, after taking this course, I feel like I've gained a clear understanding of why one should use Next.js, a React-based framework. In particular, there were many parts of the concepts of server routing and server components that I couldn't understand even by looking at the official documentation, but I was able to learn those parts through actual example code and understand them easily through the instructor's highly intuitive explanations. I used to feel like I was only superficially implementing features while working on projects. However, now, when implementing any feature, I can also consider, 'Why is this approach a better choice?' and 'What are the pros and cons of this structure?'. Thanks to this, my fear of Next.js has also disappeared, and furthermore, I've gained confidence that I can easily absorb new features no matter what version appears. This course is highly recommended for those who want to understand the fundamental principles and design intentions, not just superficial usage. I am confident that this course I took can be a turning point for developers who want to properly understand Next.js.

This is not your average introductory course that just teaches you how to write code. It delves deeply into the philosophical background and technical implementation methods of Next.js routing, data fetching, and rendering. In particular, topics such as 'How is Next.js routing implemented?' and 'Why did the params of Dynamic Route change to a promise?' help you understand 'why' it was designed that way, not just how to use it. This is the only lecture that has clearly helped me understand the essence and optimization points of Server Components, as I was only using CSR with 'use client' in practice. I feel like I can finally use Next.js properly. I'm really looking forward to the next lecture!

This is an excellent course. I've never seen a course this in-depth on Inflearn before. I could understand why Next.js was designed this way. Just trying things out without meaningful study doesn't stick in your memory even after a short time. Learning *why* it was designed this way helps it stick in your memory for a long time. It also naturally helps with interview prep. As someone who wasted a lot of money on follow-along project courses, I highly recommend this in-depth course.
The working principles of Next.js frequently asked in technical interviews
Design principles that can be applied immediately to practical work
The core philosophy and technical essence of Next.js that remain valid in the AI era
Your own criteria and perspectives for better selecting and utilizing frameworks.
Who is this course right for?
Those who have been using Next.js but find themselves speechless during technical interviews.
Those who want to grow from a 'developer who just uses it' into an 'expert who uses it with deep understanding'
Those who want to analyze the Next.js source code but feel overwhelmed and don't know where to start
Those who want to build the essential competitiveness of a frontend engineer in the AI era

Hello. I'm Boaz.
I'm an 8th-year frontend engineer who has experienced various startups through four career moves and recently left LINE.
While using Next.js across various projects, I went through a lot of trial and error.
Especially when considering better structures for practical application, questions like โWhy should it be configured this way?โ and โIs this a situation where I can use this feature?โ poured in. From that point on, I realized that 'understanding the background and operating principles' is more important than simple usage.
The goal of this course is not simply to make you "able to use" Next.js.
It was created for those who want to explore questions like โWhy was it designed this way?โ and โWhat criteria should be used for decision-making in practice?โ together.
For those of you who, like my past self, don't want to stop at simply knowing how to use it, I hope this lecture serves as a compass that provides organized perspectives and standards ๐

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).
So glad it helped..! Apologies for the quality, it's a limitation of the original video ๐ญ Thanks for studying together ๐ค

This course helped me upgrade from simply using Next.js to truly understanding its principles. Technology is constantly and rapidly changing, but understanding the fundamental principles makes it easy to adapt to changes. I recommend this to anyone who is using Next.js but has questions like, "Why is this structure necessary?" Thank you for the great course! ๐ฅฐ
