  • Loads main module from build/index.js
  • Depends on @jest/core, @jest/types, import-local, jest-cli

Data access

  • None observed

Network

Widely-used testing package with empty static findings and standard build/CLI structure; typical low-risk dependency when sourced from npm, but review updates and transitive dependencies as with any test tool.

How ShadowCanopy checks npm packages

ShadowCanopy blocks every dependency by default and only lets through what it can verify — against live malicious-package advisories, an AI behavior scan, and a byte-for-byte hash check. It protects installs across npm, PyPI, crates.io, pkg.go.dev, RubyGems, Maven Central, NuGet, Packagist, Hex, pub.dev, Swift Package Manager.
