How to setup NodeJS on Ubuntu using nodesource

Posted on March 24, 2025

Node.js is a JavaScript runtime built on Chrome’s V8 JavaScript engine that allows developers to run JavaScript on the server-side. It provides an event-driven, non-blocking I/O model, making it lightweight and efficient.

Key Features:

  • Asynchronous and Event-Driven: Node.js uses callbacks and events to handle asynchronous operations, making it ideal for real-time web applications.
  • Non-Blocking I/O: Node.js performs I/O operations without blocking the main thread, allowing it to handle multiple requests concurrently.
  • JavaScript Runtime: Node.js allows developers to run JavaScript on the server-side, making it a popular choice for full-stack JavaScript development.
  • NPM (Node Package Manager): Node.js has a vast ecosystem of packages and modules, making it easy to find and install dependencies for projects.

Use Cases:

  • Real-time Web Applications: Node.js is well-suited for real-time web applications, such as live updates, gaming, and chatbots.
  • APIs and Microservices: Node.js is a popular choice for building RESTful APIs and microservices due to its lightweight and efficient nature.
  • Server-side Rendering: Node.js can be used for server-side rendering, allowing developers to render JavaScript templates on the server.
