provenant-cli 0.0.15

//! Parser for npm package-lock.json and npm-shrinkwrap.json lockfiles.
//!
//! Extracts resolved dependency information including exact versions, integrity hashes,
//! and dependency trees from npm lockfile formats (v1, v2, v3).
//!
//! # Supported Formats
//! - package-lock.json (lockfile v1, v2, v3)
//! - npm-shrinkwrap.json
//!
//! # Key Features
//! - Lockfile version detection (v1, v2, v3)
//! - Direct vs transitive dependency tracking (`is_direct`)
//! - Integrity hash extraction (sha512, sha256, sha1, md5)
//! - Package URL (purl) generation
//! - Dependency graph traversal with proper nesting
//!
//! # Implementation Notes
//! - v1: Dependencies nested in `dependencies` objects
//! - v2+: Flat dependency structure with `node_modules/` prefix for nesting
//! - Direct dependencies determined by top-level `dependencies` and `devDependencies`
