Introduction to Node.js

Learn Node.js runtime, modules, npm, and building HTTP APIs. Free Node.js introduction for backend beginners.

Learning Outcomes

  • Explain the event loop at a beginner interview level
  • Create a project with npm and ES modules
  • Read and write files asynchronously
  • Start a basic HTTP server

Overview

Node.js runs JavaScript on the server using a non-blocking event loop — ideal for APIs and tooling.

This introduction covers modules, npm, and how a request is handled without a new OS thread per connection.

Continue later with Express, file I/O, and a small REST API.
