go install github.com/arjunsajeev/npmcheck@latest
Download the latest binary from the releases page.
Check if one or more package names are available on npm:
npmcheck my-awesome-package another-package
Output:
- ✅ indicates the package name is available

- ⚠️ indicates an error occurred while checking
# Check a single package
npmcheck my-new-package
# Check multiple packages at once
npmcheck pkg1 pkg2 pkg3
