Copyleft licenses aren't one category — the gap between GPL-style strong copyleft and LGPL-style weak copyleft decides whether linking a library obligates you to open your own code.
A GPL license explained without legal jargon: what copyleft actually requires, when it triggers, and what it means for a codebase that links against GPL-licensed code.
Node.js itself ships under a permissive MIT-style license, but your app's real license exposure comes from the hundreds of npm packages riding along with it.
