This course focuses on intensively learning the useContext and useReducer hooks for efficiently handling state management in React. Through hands-on practice, you will learn how to reduce the complexity of data transfer between components and systematically manage state in large-scale applications. By the end of this course, learners will understand the basic concepts of global state management and acquire practical skills that can be immediately applied to real-world projects.

Build and deploy community applications using the MERN Stack (MongoDB, Express, React, Node + Firebase)

Through this course, you will learn how to implement database relationships with Firebase. You can quickly become a React full-stack developer. In this era of unstable employment, you need to learn new skills and increase your value. And you need to create something. You need to be able to implement data "relationships" when implementing those side projects and ideas. This course will help you implement "relationships" with Firebase "Firestore."

Developing an AI Safety Report Service with React + Spring AI The 5th Neo + Essential project lecture is about building a Safety Report system, an idea for improving government systems!

A portfolio-focused course on deploying a React frontend and Spring Boot backend directly to the AWS cloud! This course is helpful for those who want to quickly deploy frontend and backend projects for their portfolio. You will gain the necessary knowledge for deployment through short-term, step-by-step practice, covering everything from server configuration to Docker, domain connection, Nginx, and HTTPS application!

This course is designed for developers who already have experience with programming languages (such as Java, Python, Swift, Kotlin, etc.) to quickly master JavaScript in just one hour. In an era of coding with AI, human developers must still supervise AI-generated code. This course is intended to help you rapidly build the essential knowledge required for that supervision.

You will learn the process of developing and launching your own restaurant diary app using React Native. We've prepared the entire process from design to front-end and back-end development, and deployment.

"Next.js Master Class: Part 3 - Completing Real-World Architecture" goes beyond tutorial-level projects that only run locally; it is a guide to designing "real production" architectures capable of handling massive traffic. It covers all the core technologies used in the industry, from flawless state synchronization combining TanStack Query and Zustand, to Turbopack-based bundle optimization under 100KB, advanced SEO injection, and building ironclad full-stack security networks using proxies and JWT sessions. I strongly recommend this course to those who want to overcome tedious hydration errors and CORS barriers on their own, moving beyond being a simple coder to becoming a "Senior Architect" who commands the entire frontend system.

You can learn the basics of React. You can organize HTML, JavaScript, DOM, Event, Object, Module, OOP, etc. related to React.

Real-world practice is harsh. I will perfectly pass down my essence of optimization—designed to maintain a smooth user experience even in extreme environments where tens of thousands of real-time data points pour in—through a meticulous mission system. Go beyond simply being someone who writes code and leap forward into an irreplaceable senior engineer who orchestrates performance through the principles of the engine.

This course goes beyond just using Express.js—you'll implement its internal engine from scratch to truly understand how real servers work. You'll gain hands-on experience growing as a server developer by building all of Express's components from the ground up, including routers, middleware, request-response objects, static file handling, and template rendering.

This course goes beyond simply using Express.js. You will rebuild its internal engine from start to finish, gaining hands-on experience with the real principles of how a server works. By directly creating each component of Express—such as routing, middleware, request–response objects, static file handling, and template rendering—you will grow as a server developer and truly understand how a framework operates at its core.

Based on the experience of wondering how facial recognition works in offline environments on-site, this course will guide you through building the basic structure of a facial recognition-based access and attendance management system using React + Electron and Python's FastAPI-based DeepFace. Rather than focusing on perfection, we focus on understanding the operating principles and laying the foundation for you to expand into your own personal projects.

In the era of swift execution and validation, execute faster than anyone with VIBE Coding! Achieve complete monetization, from ads to payments, all by yourself.

I recommend this to those who want to learn how to easily create and distribute Android apps, Windows apps, and iOS apps. We will teach you the basics of TypeScript rather than JavaScript and Angular!

Cultivate advanced programming language utilization skills and software design and implementation skills combining functional, object-oriented, and LISP paradigms, necessary for growing into a mid-to-senior level developer.

You will learn the basics and advanced usage of GraphQL, the next-generation API control technology, and gain real-world project experience through a virtual kiosk service created with GraphQL. The course has been partially updated to the latest version, apollo-server v4, as of February 2024.

How are you using TypeScript, the standard of Node.js? If you only add type annotations, it is not real TypeScript. I prepared everything because I don't know what you will like. Let's learn TypeScript A to Z :)

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.
