MonsterLessons is the YouTube channel and paid-course brand of Oleksandr Kocherhin, a Ukrainian developer focused on Vue.js, NestJS, and the broader full-stack JavaScript ecosystem. The channel is one of the larger independent JS / TS tutorial sources online.

His CourseFlix listing carries NestJS — Building Real Project API From Scratch. Material is paid and aimed at Node.js developers picking up NestJS through a complete project build rather than disconnected feature tutorials.

Udemy

Udemy thumbnail

Udemy is the largest open marketplace for online courses on the internet. Founded in 2010 by Eren Bali, Oktay Caglar, and Gagan Biyani and headquartered in San Francisco, the company went public on the Nasdaq in 2021 under the ticker UDMY. The platform hosts well over two hundred thousand courses across software development, IT and cloud, data science, design, business, marketing, and creative skills, taught by tens of thousands of independent instructors. Roughly seventy million learners use it worldwide, and the corporate arm — Udemy Business — supplies a curated subset of that catalog to enterprise customers.

Because Udemy is a marketplace rather than a single editorial publisher, the catalog is uneven by design. The strongest material lives in the long-form, project-based courses authored by working engineers — full-stack JavaScript, React, Node.js, Python data science, AWS, Docker and Kubernetes, mobile development with Flutter and React Native, and cloud certification preparation. The CourseFlix listing under this source is the slice of that catalog that has been mirrored here for offline-friendly viewing, organized by topic and updated as new releases land. Pricing on Udemy itself swings dramatically with the site's near-permanent sales, which is why the platform is best treated as a deep reference catalog: pick instructors with strong reviews and a track record of updating their material rather than buying on the headline price alone.

Frequently asked questions

What prerequisites do I need before taking this course?
The course requires only a basic understanding of JavaScript. Familiarity with technologies such as Angular, NodeJS, Express, TypeScript, Typeorm, or PostgreSQL will be beneficial but is not mandatory. The course is designed to help those who already have some NodeJS knowledge but need to learn how to structure and build a complete application.
What kind of project will I build during this course?
You will build a robust Medium clone API using NestJS, TypeScript, Typeorm, and PostgreSQL. The project includes creating reusable modules, controllers, and services, as well as implementing authentication mechanisms. Each lesson comes with source code, allowing you to trace your progress and have a functional application at every stage.
Who is the target audience for this course?
This course is ideal for individuals who have learned NodeJS but need more knowledge to build a real application. It focuses on the practical aspects of application creation, providing insights into structuring a project and writing clean, efficient code, rather than covering basic NodeJS concepts.
How does this course compare to other NodeJS courses?
Unlike courses that focus on introductory NodeJS concepts, this course emphasizes building a real-world application from scratch using NestJS. It covers advanced topics such as creating reusable modules, configuring databases, and implementing authentication, which are not typically included in basic NodeJS courses.
What specific tools and technologies will I learn to use in this course?
You will work with NestJS, TypeScript, Typeorm, and PostgreSQL throughout the course. Lessons cover configuring a database, generating JWT tokens, and creating entities and modules. You'll also learn to use validation pipes and middleware, as well as implementing features like user authentication and article management.
What topics are not covered in this course?
The course does not cover basic JavaScript or NodeJS concepts, as it assumes some foundational knowledge. It also does not focus on front-end development, although there is a lesson on frontend testing. The course is primarily focused on backend development using NestJS and related technologies.
What is the expected time commitment for this course?
The course consists of 38 lessons, each with a practical focus and accompanying source code. While the runtime is not specified, students should allocate time for coding exercises and reviewing the provided source code to fully grasp the material. The practical approach means you should be prepared to engage actively with each lesson.
