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

I will show you how to create web applications using JavaScript and Node.js. By using JavaScript, which runs in the web browser, you can replace the roles of PHP or JSP. This allows you to implement an entire web application using a single language.

mongoDB, NoSQL You hear a lot these days, but is it still an unfamiliar database? Aren't you using it like a relational database (RDS/SQL)? No matter how good the technology is, if it's not used correctly, it will have the opposite effect. That's why we often see cases of failure in using MongoDB. This lecture will teach you everything from basic concepts to practical know-how so that you can use MongoDB as MongoDB-like as possible.

This course will implement cookie and login functions using NodeJS, a server-side Javascript, and combine the results with the previous nodeJS course to create a complete web application.

At some point in backend development, you start to have these concerns. It's that moment when services expand and traffic increases, and you begin to feel the limitations of simple REST communication and CRUD structures. I experienced these same issues in the field and went through much trial and error balancing performance and structural complexity. The solution I chose during that process was NATS. Its simple configuration based on a single binary, ultra-low latency performance in microseconds, and the fact that it provides essential features—from Pub/Sub to Queue Groups and JetStream—without being overkill made it a very practical choice for real-world service environments. This course is not just a list of NATS features. Based on the problems I faced in practice, I explain through code and workflows why I chose NATS in certain situations and how I designed the architecture. This course is designed to help everyone—from those new to messaging systems to backend developers preparing for employment and senior developers considering better architectures—understand distributed systems and grow to the next level.

Let's systematically design the backend using the domain-driven development (DDD) method and apply it to microservices!

With the arrival of the AI era, the skills required of developers are becoming increasingly complex. You might have thought, "I just need to be good at frontend," but when you try to create your own service or integrate AI features, you eventually hit a massive wall called the backend. However, as you try to start backend development, are you overwhelmed by how much there is to learn—from database design and authentication (Auth) to storage management and complex infrastructure setup? Now, you can lay down that heavy burden. In this course, we use Supabase, which solves all these backend functions at once. We will guide you through the fastest shortcut to becoming a full-stack developer who can "instantly" complete a backend without complex server knowledge and bring ideas to life immediately.

A course to learn the latest Node.js backend REST API using fastify, a Node.js framework boasting high speed, ORM Prisma, and Typescript.

In this course, you will learn how to quickly develop a backend API through a Sajoo Manse Calendar service practice. It covers ExpressJS, Sequelize (ORM), MySQL, JWT, DB and API design, and HTTP communication.

All-in-one course: Master Node.js by building a solid foundation step-by-step from the basics 👍

An opportunity to learn both the front-end and back-end of GraphQL at once

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.

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 covers the core principles and practical techniques of Node.js that you must know before diving into professional frontend and backend development.

This is a free 1-hour introductory lecture to get you started with just the OpenAI API. You will quickly master core concepts including the Responses API, JSON response handling, validation, idempotency, and logs, while learning a practical backend workflow that allows for immediate testing without the need for external service keys.

A smooth-flowing guide to Express.js, from basics to real-world application! A backend journey to truly master everything from basic server concepts to completing a CRUD project through hands-on implementation.

Based on the lecture content, you will learn how to write a basic chat application and the basic structure of Electron and NodeJS.

This lecture is an introductory NodeJs course that even those new to programming can confidently take. NodeJs is a technology that allows JavaScript, which originally only ran within web browsers, to be used on PCs or servers. Currently, it is being utilized in various fields such as web service backends, automation, and tool development. In this lecture, 45 things that beginners should know first when learning NodeJs are easily explained in order. Learning proceeds in a slide-based lecture format, and understanding is deepened by checking actual code execution results at each stage. Because it's structured to connect 'knowledge' and 'operation', you can naturally gain "aha!" moments of realization even without direct coding. If you grasp the overall picture of NodeJs at the beginning, subsequent programming learning becomes much easier.
