What you'll learn

In this course, you will learn the fundamental concepts of Node.js and its core modules. This tool allows you not only to create web servers but also to develop desktop applications and even work with microcontrollers. By learning Node.js basics, you’ll start your path as a JavaScript backend developer, one of the highest paying jobs in the market. You will learn the numerous core modules of Node.js step by step, gradually expanding your knowledge of each module. Now, what should a beginner backend developer focus on? Let's find out.

In this course, you will:

  • Get to know JavaScript basics;
  • Learn how to work with the file system;
  • Gain database experience;
  • Create web servers;
  • Learn event-driven programming;
  • Explore ways to store sensitive data;
  • Find out how to work with streams;
  • Deepen your understanding of asynchronous programming.

Learn by doing

# 1
Apply knowledge into practice
You already know the theory. Now it's time to code like you do at work—in a professional IDE, with real project constraints, solving problems that actually matter. Welcome to software engineering as it should be.
# 2
Navigate complexity with surgical precision
Most developers waste months learning random concepts without seeing how they connect. Our interactive Knowledge Map fixes this. It shows exactly how every programming concept relates to others, helping you build a structured mental model of coding.
# 3
Copy the best. Then improve.
Here's what top engineers do that others don't: they study other people's code obsessively. When you get stuck on Hyperskill, you can explore solutions published by other developers. See their exact code. Understand their approach. Learn their tricks.
# 4
Code review that actually makes you better
We stripped code review down to what actually matters: does your solution work? Have you handled the edge cases? Is there a cleaner way to write this? Hyperskill acts like a competent reviewer who actually tests your code. Not genius-level analysis, not architecture debates — just solid feedback on making your code better.

Elevate your engineering mastery through real-world challenges

Master advanced engineering concepts through ambitious projects. Each project deepens your expertise and transforms you from an experienced engineer into an exceptional one.

Postprocessor

You've landed a new job as a Node.js backend developer at a company. Today is your first day, and the way the developers store their user data horrifies you. In this project, become the company’s savior and organize the user data in a more convenient way.

Message Decipher

You have received a coded message and you need a program to decode it. This is where the Node.js Message Decipher comes into play. This project reads the encrypted messages directly from a file, processes them using a specific decryption algorithm, and subsequently writes the decoded message into another file. At the project's end, you can encode your secret messages and write to a file too!

I really enjoyed this track. I recommend it for any beginner backend or frontend developers who want to be familiar with overall communication between server-client.

working with JavaScript in the NodeJS environment - without the browser - working with files, calculating the hash values, etc...

A good track, but some JS topics and tasks come before or without explanation of needed theory (for example a task where knowing of for-loop is needed but was not explained before).
