Building the runtime from source requires a full C++ toolchain, not just npm install.

Wtf does this do

This is the official Node.js repository, the actual source code for Node.js itself. If you've installed Node.js on your computer and run JavaScript code outside of a browser, you were using software built from this project. Node.js is a tool that lets you run JavaScript on servers and computers, not just in web browsers. It's built on top of Chrome's V8 engine (the same technology that powers Google Chrome), which means it can execute JavaScript code very quickly. Before Node.js, JavaScript was mostly trapped inside browsers. This project changed that, making it possible to write backend code, command-line tools, and desktop applications in JavaScript. The repository contains all the source code, development infrastructure, and governance documentation for the Node.js project. It tracks different release types: "Current" releases come out every 6 months with new features, "LTS" (Long-Term Support) releases provide stability for years, and "Nightly" releases let developers test cutting-edge changes. The README explains how to download pre-built versions, verify their authenticity, contribute to the project, and report security issues. It also lists the Technical Steering Committee and collaborators who maintain and guide the project. This repo would be relevant if you're contributing bug fixes or features to Node.js itself, or if you're curious about how the JavaScript runtime works under the hood. Most JavaScript developers simply download Node.js from nodejs.org and don't interact with this repository directly, but everything they do with Node.js is powered by code maintained here.
