What changed and why

  • While PackageRef.dev was already detected by lockfile parsers and displayed in terminal, JSON, and HTML outputs, the SPDX SBOM generator unconditionally labeled every edge as DEPENDENCY_OF. This caused SBOM consumers to lose the distinction between production and development dependencies during vulnerability triage.
  • SPDX Relationship Type: Updated buildDependencyEdges (fallback path reconstruction) and buildEdgesFromResolved (lockfile graph edges) to emit SPDX 2.3 DEV_DEPENDENCY_OF when ref.dev is true, while retaining DEPENDENCY_OF for production dependencies.
  • Zero shared type churn: Extracted child dev status directly from indexed packages in spdx.ts, avoiding changes to DependencyEdge or parser interfaces.
    -Test validation: Added tests in tests/spdx.test.ts covering direct and transitive dev dependencies across both path-reconstructed and graph-resolved edge modes.

Part of #1486

Summary

Summary by CodeRabbit

  • Bug Fixes
    • SPDX reports now classify direct development dependencies separately from other dependencies, including those identified through package paths or resolved dependency data. Transitive dependencies retain the standard dependency relationship.
    • Fallback dependencies in pnpm lockfiles now correctly reflect whether they are development dependencies.
  • Documentation
    • Updated SPDX documentation to describe the development dependency relationship type.

I updated pnpm fallback parsing to preserve development status. SPDX output now uses that status to mark direct root development dependencies as DEV_DEPENDENCY_OF; other dependency edges remain DEPENDENCY_OF.

Changes: SPDX Development Dependency Relationships

Layer / File(s) Summary
Record development status for fallback packages
src/parsers/pnpm-lock.ts, tests/parsers/pnpm-lock.test.ts
Legacy and v9 pnpm fallback packages now set dev based on their dependency section. A legacy lockfile test checks dev and production fallback packages.
Build and validate development dependency relationships
src/output/spdx.ts, tests/spdx.test.ts, website/docs/spdx.md
Both edge builders classify direct root development dependencies as DEV_DEPENDENCY_OF and keep DEPENDENCY_OF for other edges. Tests cover direct and transitive dependencies, resolved edges, and valid relationship types. The documentation lists both relationship types.

Transitive dependencies now retain ordinary dependency relationships. Mixed production/development packages remain a bounded SPDX classification concern; merging warrants owner awareness of that limitation.

Full details: Title check

Explanation

The title uses the required "type: short description" form with the feat type and a lowercase description, and it has no trailing period. It names the actual change: SPDX dev dependencies now use the DEV_DEPENDENCY_OF relationship. The scope "(spdx)" also matches the touched SPDX generator. The title does not include a leading "feat" with a colon exactly as the requirement shows, since it adds a scope in parentheses, but the type is on the allowed list and the rest of the format holds. The title is specific and matches the changeset.

Full details: Description check

Explanation

The description explains the problem: the SPDX generator labels every edge as DEPENDENCY_OF, so consumers lose the production versus development distinction. It lists the code changes in buildDependencyEdges and buildEdgesFromResolved, notes that no shared types or parser interfaces changed, and describes the new tests. It also links the work with "Part of #1486". The template asks for a "Closes #" line. The PR uses "Part of #1486" instead, and the template's required "Closes #" issue reference is missing. The description otherwise covers the "What changed and why" section well.

Full details: No New Runtime Dependency

Explanation

The pull request changes five source, test, and documentation files. It does not change package.json or any other package manifest. Therefore, it adds no entry under dependencies or optionalDependencies and moves no package from devDependencies.

Nitpick Use constants for the relationship-type strings.

326-326: Trivial · Maintainability & Code Quality · Quick win

Use constants for the relationship-type strings.

Both builders repeat "DEV_DEPENDENCY_OF" and "DEPENDENCY_OF". Define shared constants so the two output paths use the same tokens when their selection logic changes.

As per path instructions, “Flag repeated string literals that should be constants.”

Thanks @Nachiket-Roy. The labelling itself is sound: no package ends up with both a dev and a normal edge into it, mixed packages stay DEPENDENCY_OF, the total edge count is unchanged, and every output I generated validates against the SPDX 2.3 schema from #1474, across npm, pnpm, Yarn and Bun.

One design point before it goes in. SPDX types the edge, so A DEV_DEPENDENCY_OF B says B uses A for development. Putting it on every edge into a dev-only package carries that down the tree: on nest, diff-sequences becomes a dev dependency of jest, though it's a runtime dependency of jest, and on analog 71 edges tell a production package one of its own dependencies is dev-only (a production babel helper and its @babel/core, for example). Could we use DEV_DEPENDENCY_OF only where the parent is the root project or a workspace member, and keep DEPENDENCY_OF further down? Dev-only status is still recoverable by walking from the root.

Also, could you add DEV_DEPENDENCY_OF to the relationships row in website/docs/spdx.md so the docs match the output?

Minor follow-up Keep dev on pnpm legacy fallback dependencies.

327-331: 🎯 Functional Correctness | 🟡 Minor | 💤 Low value

Keep dev on pnpm legacy fallback dependencies.

In a pnpm lockfile below v9, a devDependency with an npm: importer value takes the fallback path in loadLegacy. That path omits dev, so its SPDX edge becomes DEPENDENCY_OF. Pass the section flag to fix it. upsertPackage still prefers production status on merge.

Suggested fix
             upsertPackage(map, {
               name: String(depName),
               version: fallbackVersion,
               ecosystem: "npm",
+              dev: depSectionName === "devDependencies",
               paths: [["project", String(depName)]]
             });

Update the npm importer fallback in loadLegacy to pass the dependency section’s
dev status to upsertPackage, so devDependencies retain dev metadata for SPDX
edge classification; preserve upsertPackage’s existing production-preferred
merge behavior.

Nitpick Add a v9 test for the fallback dev flag.

695-695: Trivial · Maintainability & Code Quality · Low value

Add a v9 test for the fallback dev flag.

The new test covers only legacy lockfiles. The v9 fallback sets dev at src/parsers/pnpm-lock.ts:218, and no test asserts that value. A regression on that line would not fail the suite.

The v9 fallback runs only when normalizePnpmDepRefV9 returns null. The npm: prefix produces that result, and the legacy test already uses it. Add a v9 test with the same shape:

Fixture shape
lockfileVersion: '9.0'
importers:
  .:
    devDependencies:
      fallback-dev: npm:1.0.0
snapshots: {}
packages: {}

Assert that fallback-dev has dev set to true.

This value is not the form pnpm writes for v9 aliases. It reaches the branch because the loader does not normalize the npm: prefix.

Review comment at @tests/parsers/pnpm-lock.test.ts at line 695:
Extend the test coverage around “preserves dev status on fallback dependencies
in legacy lockfiles” with a v9 lockfile case that reaches the fallback path for
an unnormalized dependency reference. Assert that the fallback dependency’s dev
flag is true, while keeping the existing legacy test intact.

Thanks @Nachiket-Roy, this is the shape I was after. On nest, analog and workspace every DEV_DEPENDENCY_OF edge now comes from the root project, the jest case from last time is gone, and the docs row matches. Reverting either route back to labelling every dev edge, or dropping the pnpm fallback dev flag, fails the new tests, and the full suite passes on the merge with current main. Approved.

One optional follow-up, no need to hold this for it: a workspace member's own dev dependencies still come out as DEPENDENCY_OF. That loses a little detail but never says anything wrong, so it can be its own change if anyone wants it.
