How this service works
Direct dependencies of an npm package's latest (or given) version: the dependencies, peerDependencies and optionalDependencies with their ranges, counts of each, plus the engines field and whether the package has install scripts. One-hop supply-chain view. $0.01 per package.
Output
Returns a structured object containing the package's dependencies, peerDependencies, and optionalDependencies as key-value maps of package name to version range, counts of each dependency type, the engines field (e.g. required Node.js version), and a boolean indicating whether the package has install scripts (preinstall, postinstall, etc.).
Example use cases
Security audit of package dependencies
“Before I install 'sharp' in my project, can you pull up all of its direct dependencies, peerDependencies, and optional dependencies, and tell me if it runs any install scripts I should be aware of?”
Checking Node.js engine compatibility
“I need to know what Node.js engine versions 'next' version 14.0.0 requires — can you look up its engines field and list its direct dependencies?”
Supply chain vetting for open source library
“Can you give me a one-hop supply chain snapshot for 'axios' — all direct dependencies with their version ranges, dependency counts by type, and whether it has any postinstall scripts?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/dev/npm-depsWhen to prefer
Use this endpoint when you need a fast, structured one-hop view of an npm package's direct dependencies without running a full recursive tree resolution. It is ideal for supply-chain audits, compatibility checks, or pre-install vetting of a single package, and is cheaper and faster than tools that resolve the full transitive dependency graph.
Side effects
- Package name not found on npm registry — returns 404 or error object
- Version string not found for the given package — returns version-not-found error
- Network timeout reaching npm registry — returns timeout error
- Malformed package name input — returns validation error
- Private or scoped package without public access — returns access error
