Building a solid foundation of basic concepts, One-bite Vibe Coding
Vibe Coding is incredibly fast.
But because it is so fast, it passes by
with the basics missing.
If you lack the basics, it will eventually collapse.
You will lose control over the AI's output.
However, you can't learn such vast development knowledge
all from the beginning.
What should you do?
So, I've narrowed it all down for you.
STEP 00.
Before developing with AI, we will first examine what AI tools can help with and what their limitations are.
Key Learning Content
STEP 01.
To use AI development tools, learn how to manage a computer using commands.
Key Learning Content
STEP 02.
Directly install and get hands-on experience with AI coding tools like Claude Code and Codex.
Key Learning Content
STEP 03.
You will grasp the big picture of how the web works by directly building and understanding how browsers and servers communicate with each other.
Key Learning Content
STEP 04.
We create a safety net with Git so that you can revert to a previous version at any time, even if AI messes up the code.
Key Learning Content
STEP 05.
Build quickly on top of a proven foundation (framework) that eliminates the need to start from scratch every time.
Key Learning Content
STEP 06.

What makes this lecture different
Intuitive animated visuals are provided so that even complex concepts can be organized at a glance.
We provide clear diction and high-quality audio that remains easy to understand even at high playback speeds, ensuring you don't miss a single word.
"The voice delivery is insane.. Teacher, it sticks to my ears even at 1.5x speed ㄷㄷ"
"Thanks to the diction that allows every single word to be heard clearly even at 2x speed, I was able to finish the course quickly."
"The instructor's vocalization is so good that even when I increase the playback speed, I can understand everything perfectly."
"The course content is great, and even when listening at 2x speed, everything is very easy to understand."
"The fact that the voice is clearly audible even at 1.5x or even 2x speed (even though I'm a bit hard of hearing..)"
This is not your typical PDF summary. We provide a book where live demos and animations come to life.
Not just static images, but animations that show the flow so you can understand it all at once.
Not just reading and finishing, but being able to check the operation immediately within the page.
Every single prompt that appeared in the lecture has been included without missing a single line. Just copy and paste them whenever you get stuck.
For 5 years, I have been with over 40,000 students on Inflearn.
Real stories left by students who have experienced the "One Bite" series.
This is the first online course I have ever completed in my life. The instructor's diction is excellent, and above all, the course content is very substantial.
It's really great because there are plenty of visual materials and many examples that help with understanding! As expected, the Bite-Sized series is the best!
I only intended to take one bite, but I keep coming back for more of the One-Bite series. It's fun and informative—this lecture is totally lucky-vicky~~
It feels like eating pork neck wrapped in perilla leaves. The course content isn't greasy; it's delicious~
I was wondering if I could ever make something like this, but as I followed the easy and detailed step-by-step explanations, it was amazing to see it gradually come to life.
The instructor teaches with clear diction at a moderate pace. When I reviewed the material, I listened at a faster speed, and because the diction was so good, I had no issues at all!

I don't usually leave reviews, but I'm leaving one because I'm so satisfied with this course. I think it was the best among all of Junghwan's lectures.
It makes no sense for this price to include such great explanations and content. You could have easily charged double.
It's great because it contains all the core points I wanted to learn, and it's even more helpful because the content is explained in an easy-to-understand way.
This is the only course on Inflearn that I have completed from start to finish. The concise explanations are easy to understand, and the handbook is excellent for reviewing.
Thanks to the perfect quality and explanations that lived up to my expectations, I learned so much that my career gap felt insignificant. Thank you sincerely for lighting my path once again.
I was able to easily understand everything from basic concepts to the operating principles of SSR, SSG, and ISR through visual materials and animations.
I don't usually leave course reviews, but I'm leaving one now because I'm so satisfied with this course. I think this was the best among all of Jeonghwan's lectures.
It makes no sense for a course with this level of clarity and content to be at this price. You could have easily charged twice as much.

This course requires a paid Claude Code subscription (Pro plan or higher).
Since Claude Code is used as the main AI tool, the free plan has usage limits that may restrict your ability to follow the hands-on exercises. Starting your subscription at the beginning of the course will allow you to use your costs most efficiently.
Claude 플랜 안내 보기 →Codex users can also fully participate in the course.
The lectures are based on Claude Code, but I have prepared separate supplementary materials for those using other AI coding tools such as Codex. Even if you use a different tool, you will be able to follow the course content without any issues.
I am not a developer, but someone who builds websites using WordPress. To start Vibe Coding, I looked into three different books and many YouTube lectures. The most helpful parts of this course were version control, authentication, security, and deployment. In particular, version control using Git/GitHub was something I couldn't properly understand when studying on my own, but I was able to grasp it clearly through this course. Also, setting up Kakao Login was difficult to apply even after trying it once before, but I understood it perfectly thanks to the instructor's clean explanation. What I liked most was the instructor's delivery. The pronunciation was precise and the explanations were clear, making it easy to understand. I believe this is the most practically helpful course for non-developers who want to create results using Vibe Coding.
It was so much fun that I breezed through all the way to lesson 19 in one go! These early lessons have made me really curious about what kind of classes I'll be taking in the future. Even though I'm a non-major, you explain everything so easily and interestingly that I'm really enjoying the course! I'll keep working hard until the very end!
I am a semi-developer who minored in Computer Science! I’ve tried developing many ideas in the past, but I have very little experience actually finishing (deploying) them. Through this lecture, I was able to review and re-acquire foundational knowledge and apply everything down to the rewarding feeling of deployment—it was a truly valuable experience! The biggest strength of this lecture is that it doesn't just list how to use specific tools; it clearly points out the unchanging "core concepts" of collaborating with AI through a 3-step process (AI usage → Core foundational knowledge → Project development). Thanks to this, I felt like my actual mindset for utilizing AI was being established. After learning about Claude Code introduced in the lecture, I proceeded with a project using Gemini CLI to suit my personal environment. By mastering the flow from code writing to debugging via AI, I was able to develop much more efficiently. In particular, I used Vercel CLI for the final deployment process. Applying the "Vibe Coding" flow I learned in the lecture made the deployment process incredibly concise. For those who haven't tried it yet, I'll leave the sequence of core commands I used: 1. Install Vercel CLI in the project: npm install -D vercel 2. Login authentication: npx vercel login 3. Project setup: npx vercel (Proceed with settings according to the prompts) 4. Deployment: npx vercel deploy I highly recommend this to anyone who wants to efficiently complete their own projects using AI. Whether you are a major like me or a beginner, it was a valuable lecture where everyone can gather a bite and a slice to complete a whole pizza or a whole cake! Thank you!
Each lecture was so informative and interesting that I stayed fully immersed and finished the entire course quickly! The content was concise, and I was especially surprised by the high quality of the handbook. It's amazing how you prepared such a comprehensive course! This was my first time using Claude Code, and I really felt how fast AI technology is advancing ㅠㅠ By completing a project myself using the "Vibe Coding" method, I now have a good sense of how to approach future toy projects! 🫶 Also, you speak so well that you sound like an announcer ㅋㅋㅋㅋ You're the best!!!
