1. Considering that the lecture difficulty is intermediate or higher, I think it is a very appropriate or even easy level of difficulty. I think most intermediate learners will be able to search and resolve errors caused by version issues and such. 2. Also, since the importance of docs was continuously emphasized during the lecture, it was fun to look up parts I didn't understand on my own. The explanations were also kind. 3. I learned a lot from the fact that he explained well why and how to use Nestjs using examples from his practical experiences and situations. 4. I learned a lot from the live Q&A part for each section. I want to participate in an actual live lecture next time.

What you will gain after the course

  • NestJS

  • Comparison with Express

  • TypeORM

  • Unit testing, e2e testing

  • API Design

Build your own chat app, all the way to server development!
Meet the trendiest framework these days, NestJS.

From Express
to NestJS!

I originally used Express as my server framework and Sequelize as my DB at work. However, I kept hearing so much about NestJS in the community that I decided to give it a try, and... my eyes were opened👀!
Since then, I have migrated all of our company services to NestJS and switched from Sequelize to TypeORM.

The Spring of the Node world,
the hot NestJS 🔥

NestJS, known as the Spring of Node.js! It is said that even developers who left Node to pursue Spring are returning because of NestJS. Compared to the widely used Express, how is NestJS different and how powerful is it? In this course, we introduce the features of NestJS. We will convert a web server built with Express to NestJS and build the backend part of a web app similar to Slack ourselves.

Then, shall we learn for ourselves why NestJS is so hot right now?

Frequently Asked Questions 💬

Q. Do I also need to take the [Slack Clone Coding - Real-time Chat with React!] course? I'm not interested in the frontend.

If you are only interested in server development, you only need to take this course. However, when doing backend coding, you need a frontend to send requests to the backend, right? That's why I have already completed the frontend code. You just need to run the frontend code. Use the frontend screen to send requests to the backend.

Q. Do I need to know Express? I want to skip Express and just do NestJS.

There are parts of the lecture where Express is introduced or compared with NestJS. You need to be able to read Express code to some extent for a smooth learning experience. Since NestJS uses Express internally, a basic understanding of Express is recommended.

Please note before taking the course!

  • Nest.js uses version 8. It will be smoother to follow the course using version 7 or 8.
  • The actual deployed service can be checked at sleact.nodebird.com.
  • The lecture syllabus is available here.
  • I will compile frequently asked questions into an FAQ and post them on the Inflearn blog.
  • If there are any issues with the video or content, please contact me and I will re-edit and upload it.
  • If there is something not covered in the lecture that you are curious about how to implement, I will create a bonus video if many people ask about it.

    There is a part in the middle that shows migration from express to nestjs, but it is not easy to follow this part for someone who has not taken the existing lecture. There is also the DB table creation and a webpack error that suddenly appears... I think you should make a lecture for people who have not taken the express lecture...

    The technology stack that I want to learn is mainly covered by Zerocho, so I signed up for almost all of the lectures, but the lecture-style on YouTube doesn't seem to suit me. Should I say it's chaotic and distracting? It feels more like he's commentating while playing Starcraft than teaching in a straightforward manner?? He just mentions things and passes them over, and I keep thinking that I'll look them up later... Before the lecture starts, he says, "What will I explain today?", and then he organizes them and tells me. If you can't follow along, this is the final version of today's lecture. I think this kind of lecture suits me. The content is not bad. Honestly, I hesitated to leave a review even after attending so many lectures because I felt burdened by leaving a bad review, but since I paid for the lecture, I'll leave my honest opinion. I'll watch the old lectures and leave as many reviews as possible. Lastly, he answers questions very well. He has recorded many lectures, and some of them are quite old, but I think it's really great that he maintains them while answering questions! I hope you'll continue to give us great lectures in the future.

      I liked the part where you explained the differences with Express. I was impressed by how you had a lot to say and how you tried to teach as much as possible. However, I wish you were a little more friendly. I saw the answer to another person's question, and it seems like the person asking the question has to be careful. I think it's a bit strange to tell people to think about their questions and not just follow along without thinking. The instructor is good, so that may be the case, but I hope you don't forget that most of the people watching this lecture are beginners in NestJS. I'm enjoying the lecture.

      • zerocho
        Instructor

        Thank you for your opinion. However, my opinion has not changed. I think there are two types of students. One type is those who really want to study, and the other type is those who just follow along and get results. I want only those who really want to study to take my class, even if it means making less money. That is why I do not accept questions like, “No, you can’t follow along.” I do not want to hear people say that my lectures were not helpful.

      The lecture preparation is very disappointing. There are many cases where the learner has to wander along with them, so it is somewhat difficult for the students to grasp the concepts.

      • zerocho
        Instructor

        I'm sorry for replying late. I think it may have been inconvenient because it was an edited version of a live lecture. So I wrote a lecture outline (https://github.com/ZeroCho/sleact/blob/master/nest-typeorm/README.md) where you can check your progress from time to time on GitHub, and a file that separates the source code by section (ch0, ch1, ch2...). I will actively reflect your feedback in the future. Thank you.

      It was good, but I haven't seen the previous lectures, and although it's unrelated to the previous lectures, I think there are too many examples from those lectures, so I think that part is a little difficult.

      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.

      As you work in backend development, you eventually find yourself facing a certain concern. As services multiply and traffic increases, there comes a point when simple REST communication and a CRUD-only structure begin to show their limitations. I experienced the same problem in practice and went through many trials and errors trying to balance performance with structural complexity. The solution I chose in that process was NATS. Its simple, single-binary-based setup, ultra-low-latency performance measured in microseconds, and practical feature set—from Pub/Sub and Queue Groups to JetStream—made it a highly realistic choice for actual service environments. This course is not about listing NATS’s features. Based on the problems I encountered in practice, it explains through code and workflows when and why I chose NATS and how I designed the architecture. From those new to messaging systems, to backend developers preparing for employment, and senior developers considering better architectures, this course will help everyone understand distributed systems and grow to the next level.

      Do you add type annotations, yet do invalid data still only blow up at runtime? This course, based on TypeScript 7, covers everything from designing domains so invalid states cannot compile in the first place to writing programs that run inside the type checker. You’ll build five CLIs yourself, and by the end, complete a compiler that compiles your own small language into JavaScript.
