Bite-sized Next.js

Master JavaScript and React all at once with this course, covering everything from core concepts to unique projects. An all-in-one, 18-hour course designed for short learning and long application!

Go beyond syntax to understand the principles and concepts—if TypeScript still feels confusing no matter how much you study, it's time to learn it properly! We will turn you into a TypeScript Wizard🧙🏻‍♀️.

AI is only as good as you are. Master "Vibe Coding" through a three-step process: AI utilization, foundational core knowledge, and project development. For those who want to learn Vibe Coding properly, we deliver the unchanging core concepts—applicable to any AI—in bite-sized pieces.

If you keep getting errors after asking AI to do it, the problem isn’t the AI—it’s that you lack the foundational knowledge to guide it. In this video, we’ll cover the seven foundational concepts that people who get stuck while vibe coding were missing, and explain what each one is and why it’s necessary. 👾 This is explained for people on day zero of coding who have never opened a terminal before.

Now it's time to take on a real-world challenge 🔥 We will develop a production-grade SNS using React.js + TypeScript + Supabase, building features such as authentication & authorization, infinite scroll, image uploads, likes, infinitely nested comments, and dark mode. In the process, we will also explore server and global state management techniques using Zustand and Tanstack Query.

Upgrade your React app with Zustand, Tanstack Query, and Tailwind CSS! We guide you through the core concepts and usage of various tools so that you can take on even complex projects.

This course is a practical-focused learning program for JWT-based token authentication and security enhancement techniques that are essential in modern web service environments. Using Spring Boot 3, Spring Security 6, and React, you'll implement secure login systems and cover comprehensive security practices including XSS·CSRF countermeasures, HTTPS implementation, token reissuance and revocation strategies, and secure secret key management. Additionally, you'll practice real service-level environment configuration through AWS build·deployment and performance optimization using Redis, and the complete project source code provided in the course can be directly applied to real-world work.

"A hands-on web development project course that covers everything from planning and design to implementation and deployment using Generative AI." We will complete the entire process together step-by-step—starting from idea conception, quickly creating designs with AI, implementing a functional website with React, and finally deploying it to the internet. Latest AI tools like Stitch and Figma Make will assist with your design work, and even complex coding will be taught in a way that is easy to follow step-by-step.

In this 24-hour tutorial, you will learn how to build your own YouTube clone. We will cover advanced topics such as Next 15 and React 19 (including tRPC), prefetching in Server Components, utilizing Suspense in Client Components, video processing, background jobs, and AI features.

This is a practical project course on running Whisper locally and quickly developing an AI speech recognition app using FastAPI and Next.js. You'll implement real-time speech recognition and complete a project that can be used as a simple portfolio piece in a short amount of time.

This course teaches you how to build a web application using React and Firebase, implementing core features used in real-world services such as login, post management, file uploading, and profile management. You will build a complete web service step-by-step, implementing email and social login via Firebase Authentication, Firestore-based data storage and real-time data processing, file uploading using Firebase Storage, and profile management features. This course is designed for frontend developers to understand how to quickly implement web services using Firebase without the need for complex server construction.

🔥 This is a practical full-stack course where you will implement the knowledge-sharer features from scratch, from course registration to video uploading. Using Next.js 15 and NestJS, you will follow the actual Inflearn workflow—creating courses, organizing curriculums, uploading thumbnails and videos, and writing detailed descriptions—while gaining hands-on experience in Prisma modeling, JWT authentication, S3 + CloudFront uploading, and Swagger API design.

We will develop an avatar-based community app using React Native. You will learn the process of creating a high-quality community app that includes not only post creation but also comments/replies, likes, polls, and avatar generation.

Supabase, the wings for your full-stack development! Through three clone projects, you will quickly learn how to perform professional-level full-stack development using Next.js 14 and Supabase.

A current startup CTO will share vibe coding knowledge gained through actual services and various outsourcing projects.

Practice REST API and GraphQL while creating a simple SNS service based on React. We introduce how to easily and simply create a backend environment for frontend development.

This is a practical course where you will directly create a timer app using React, Electron, and Zustand, and even deploy it to cross-platforms (Windows, macOS, Linux). Starting with familiar React web development, you can learn the entire flow of desktop app development, including global state management via Zustand and final GUI deployment!

While LLMs are currently transforming the development environment, what truly matters is not just "writing code on your behalf" but integrating them as features into a service. This course provides a step-by-step guide to implementing a lightweight yet polished Tarot reading service using Next.js and the OpenAI API. In the first stage, we will build an MVP that works without a backend, connecting the user input flow (questions/threads/card selection) to result generation. In subsequent stages, we will expand the functionality by building a backend, implementing general login and OAuth, adding community features, and creating a reading dashboard. Finally, we will conclude by deploying to AWS and integrating Google AdSense to complete a service ready for actual operation. Additionally, we will cover understanding pricing structures and cost optimization strategies to ensure that LLM API usage costs do not become a burden.

This course will help you develop mobile apps that can be serviced on Android and iOS using web development.

This course helps you understand the entire flow of backend development by building everything from an HTTP server to an AI service step-by-step. You will develop the ability to read and understand AI-generated code while learning core concepts such as servers, databases, HTTP, login, and deployment, along with practical applications of Node.js, Express, and NestJS through hands-on practice.

This is mission content for a development project. We provide a PRD planning document, Figma designs, and API endpoints so that you can practice by implementing a timer app called DevTime yourself. Make the knowledge you have learned completely your own by implementing a project at a level similar to an actual service 🚀

This is a course for those starting with TypeScript. The curriculum has been designed so that even those unfamiliar with modern JavaScript syntax can learn easily. Let's learn TypeScript, which may seem difficult, in an easy and fun way from a beginner's perspective 😄
