I can understand pre-existing development environments. I can create a development environment from scratch.

Master React now. Easiest course to grasp React's features & roles, comparing to pure JS!

In this course, you will learn NodeJS, which allows you to develop backends using the Javascript language, and develop API servers using NodeJS using the test-driven development (TDD) method. You will also understand the basic principles of ExpressJS, a representative web framework for NodeJS, and learn how to develop REST APIs used in mobile and web services.

You can learn intermediate Vuejs techniques (Vuex, Vue-Router, Http) through the process of implementing other web applications with your own hands. This is a lecture where you can also experience how to collaborate, as publishing results, API servers, and documentation are pre-configured.

Even if you create the same function, the code of a junior developer who has just learned JavaScript syntax and that of an experienced senior developer will be quite different. Of course, even if the results are the same. The reason the latter's code is recognized is because of its well-designed structure and scalability to respond to changes. This lecture will learn about how to create such good code.

We will learn VueJS development by creating a shopping mall search page using pure JavaScript and a UI library called VueJS. You can learn the differences between each development and the differences between MVC and MVVM design patterns by developing with pure JavaScript and VueJS respectively.

Learn the fundamentals of the web, networks, and HTTP that every developer should know, in a code-based, real-world, data-driven way.

✅ Among the series of (1) ~ (7), (7) web applications, networks, clouds, WWW, information security ✅ CS101 series lectures - From basic computer theory to the latest practical examples - Provides a wide range of basic knowledge

From TCP/IP to HTTP! This course is prepared for those who lack basic network theory but hope to understand major-level concepts, even if it means "memorizing" them. You can do it!

I want to launch a side project as a real service and study Kubernetes, but managed services from AWS/GCP (EKS, GKE, etc.) are too expensive. On the other hand, running it only on a local computer makes it difficult to experience network configurations or actual deployment environments. We will utilize the "Always Free" tier of Oracle Cloud (OCI), which offers the most powerful free benefits among existing public clouds. By installing the lightweight yet powerful k3s, we will build a Linux server and Kubernetes environment capable of hosting actual services from scratch—all at zero cost. After taking this course, you will gain a general understanding of cloud networking and possess your own Kubernetes cluster infrastructure where you can deploy and operate your applications for free.

This is a course where you create a mini RPG 2D game to learn 2D development techniques, and then learn the process of converting the completed game into a network game by transitioning it to Netcode for GameObject. It covers various essential tilemap functions for 2D games, and is designed to naturally help you learn clean code writing techniques that adhere to SOLID principles. Additionally, this is a lecture that builds the foundation for network games using the updated Netcode API in the latest Unity 6 version.

Learn the core HTTP features essential for practical use and how to design proper HTTP APIs.

Arduino? Coding? You don't need to know anything. Just invest a little bit of your free time and you'll find something amazing.
