Node.js Overview
Node.js is a Free (MIT) development tool for Windows and macOS and Linux maintained by OpenJS Foundation. The Node.js offline installer is a self-contained standalone setup file — every library, runtime dependency, and interface asset is bundled into the package so installation completes without an internet connection at any stage. The Node.js standalone installer satisfies that requirement directly. Node.js delivers a focused set of developer-oriented features: syntax highlighting and code completion speed up day-to-day work, an integrated debugger reduces context switching, and the plugin architecture extends the core with language-specific tooling. To install offline: download the Node.js full setup from the official release page, transfer to USB if needed, and run on any compatible Windows and macOS and Linux machine. Download the Node.js standalone setup from the official source to start a reliable, reproducible development environment.
