The Easiest Node.js - by Yalco

Learn React the easiest and fastest way with Explainer Captain Yalco's rich and solid course!

The ultimate full-stack course that teaches even beginners about web, server, mobile apps, and machine learning!! If you're not sure where to start with development, I highly recommend this course. It's all done with just Javascript!

This course covers how to create a web application that uses JavaScript to control Node.js and dynamically generate HTML code.

Create a SNS service using Vue and Nuxt frameworks. Learn the full stack knowledge required for the service.

You can understand the JavaScript engine V8! You can get hints on how to write more efficient code.

This course is not about "Let's build something amazing with the latest technology," but rather the most practical web development beginner course that makes you feel "You can build it yourself with just a little knowledge." We'll create the basic structure with HTML and JavaScript, exchange data using Node.js and SQLite, and complete a simple web page with Next.js. We minimize complex configurations and difficult theories, and focus on getting a hands-on feel for web development flow by writing code that actually works. This course centers on 'hands-on experience' rather than just 'learning.' If you've touched code even a little bit, anyone can follow along and feel the satisfaction of completion.

We will create a Twitter-like SNS service using the React & Next & Redux & Redux-Saga & Express stack. Finally, we will perform search engine optimization and deploy it to AWS.

The days of feeling relieved by black-box code spat out by AI are over. By piercing through the physical limitations of computers and the inner workings of the Node.js core engine, we provide you with the engineering control to remain unshakable in the face of any traffic surge.

This is a fast-paced development course for busy planners. You can learn the entire development process by developing web front-end, back-end, and DB yourself with simple explanations.

Understanding Spring Boot + React.js Login (+Social) Service is a course designed to help you deeply understand the authentication flow between frontend and backend, by directly implementing a practical login system that includes JWT-based authentication and social login (Kakao/Google). The frontend is built on React.js, and the backend on Spring Boot, enabling you to learn step by step the practices used in real service environments, such as the Access Token + Refresh Token approach, user state management using HttpOnly Cookie and Redux, Role-based authorization, and social login integration.

If you want to understand TypeScript properly, you should read the official documentation at least once, right? This lecture will convey only the important parts of the documentation in an easy-to-understand manner, and also teach you the content you need in practice!

Hashing, salting, JWT, symmetric and asymmetric keys, and even HTTPS and TLS. The backbone of security that we use every day yet always found vague and unsettling. If we have to face the countless neglected threats and technical debt someday, let’s properly tackle them once and for all this time.
