Detect Express in any GitHub repo

Express is the minimal, unopinionated web server framework for Node.js and still the most common base for JavaScript APIs.

Why show Express on your README

Backend repos rarely advertise their server framework; detecting Express from package.json makes the API side of a project visible.

How Express is detected

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

  • Files or folders: express.config.js, .express
  • Dependencies in package.json: express

Express README badge

A static badge you can paste anywhere in Markdown:

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 Express (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.
