GitHub package.json Peek

See outdated npm dependencies directly in GitHub's package.json view.

GitHub package.json Peek shows live npm version badges directly inside GitHub’s package.json view. Open any repository and instantly see whether each dependency is up to date — no copy-pasting, no external tools, no extra clicks. What you get Every dependency gets a colored badge next to its version string: 🔴 Major update available — a breaking change is available 🟠 Minor update available — new features are available 🟢 Patch update available — bug fixes are available ✅ Up to date — you're already on the latest version How it works When you open a package.json file on GitHub, the extension fetches the latest version of each package from the npm registry and injects badges inline, right next to the existing version strings. Supports both dependencies and devDependencies. Why it's useful When auditing a new codebase or browsing open-source projects, you can instantly see which packages are outdated without leaving the page. Lightweight, fast, and no sign-in required.
