Detect Node.js in any GitHub repo

Node.js is the JavaScript runtime built on V8 that powers most server-side JavaScript, CLIs and build tooling.

Why show Node.js on your README

The card shows Node alongside the package manager (npm, pnpm, Yarn or Bun) so contributors know which lockfile to respect.

How Node.js is detected

Stack Fingerprint reads the repo's full file tree in one GitHub API call and flags Node.js when it finds any of these:

  • Files or folders: .nvmrc, .node-version, .npmrc

Node.js README badge

A static badge you can paste anywhere in Markdown:

![Node.js](https://img.shields.io/badge/Node.js-5FA04E?style=for-the-badge&logo=nodedotjs&logoColor=white)

Or let the repo describe itself

Static badges go stale the moment you swap a dependency. A Stack Fingerprint card is generated from the repo, so Node.js (and everything around it) appears or disappears on its own:

Replace OWNER/REPO with your repository, or open the builder to pick a theme and layout.
