Detect Yarn in any GitHub repo

Yarn is one of the package mgr technologies Stack Fingerprint recognises automatically when it scans a public repository.

How Yarn is detected

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

  • Files or folders: yarn.lock, .yarnrc.yml, .yarnrc

Yarn README badge

A static badge you can paste anywhere in Markdown:

Yarn badge

Markdown
![Yarn](https://img.shields.io/badge/Yarn-2C8EBB?style=for-the-badge&logo=yarn&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 Yarn (and everything around it) appears or disappears on its own:

README.md
[![Stack Fingerprint](https://stackfingerprint.vercel.app/api/card?repo=OWNER/REPO)](https://stackfingerprint.vercel.app/?repo=OWNER/REPO)

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