An npm scan with --prod-only --check-licenses still reported copyleft and unknown-license findings for dev-only packages, even though those packages were excluded from the vulnerability inventory.

Pass the production-only option through single-folder and multi-folder scans and skip npm lockfile entries marked dev, matching the existing inventory parser. Existing callers retain full-tree scanning by default, and packages shared with the production tree remain included.

Regression tests exercise package-lock v2/v3, npm-shrinkwrap, and the multi-folder CLI path. They cover both LC001 and LC002 findings, default full-tree behavior, and a package declared as a dev dependency that is also reachable through a production dependency.

Closes #1509

Summary

Summary by CodeRabbit

• New Features
  • Added a --prod-only option to limit license findings to production dependencies in single-folder and multi-folder scans.
  • Without this option, scans continue to include development dependencies as before.

When --prod-only is active, npm license scans now exclude lockfile entries marked dev. The option reaches license detection in single- and multi-folder scans. End-to-end tests cover npm lockfile versions 2 and 3, shrinkwrap version 3, and filtered and unfiltered scans.

Changes: npm license filtering

Layer / File(s)	Summary
Option propagation and npm filtering src/licenses/license-check.ts, src/scan/single-scan.ts, src/scan/multi-folder-scan.ts	License detection accepts the optional prodOnly option. Single-folder and multi-folder scans pass it to license detection. When enabled, the npm lockfile scan skips entries marked dev.
End-to-end validation tests/e2e/license-prod-only.test.ts	Tests compare findings with and without --prod-only across npm lockfile versions 2 and 3, shrinkwrap version 3, and multi-folder scans. They check that production-reachable findings remain and development-only findings are excluded in filtered scans.

Production-only license filtering has regression coverage. Adding a production finding in the second-folder fixture would strengthen coverage but need not block merging.

Explanation

The description explains the problem, implementation, affected scan paths, regression coverage, validation results, and linked issue. It does not include the required "## What changed and why" heading, but the required content is otherwise present and complete.

Full details: Linked Issues check

Explanation

Issue #1509 requires production-only license scans to exclude npm packages that exist only in development dependencies. The change passes prodOnly through single-folder and multi-folder scans and skips lockfile entries marked dev. The default remains full-tree scanning because prodOnly defaults to false. The reported tests cover lockfile v2, lockfile v3, npm-shrinkwrap, LC001, LC002, multi-folder scans, default behavior, and packages reachable from the production tree.

Full details: Closes Keyword Matches Scope

Explanation

The body uses “Closes #1509”. Issue #1509 asks production-only npm license scans to exclude packages marked dev, while retaining production-reachable packages. The PR passes prodOnly through single-folder and multi-folder scans, filters dev lockfile entries, preserves the default full-tree behavior, and adds coverage for npm lockfile v2/v3, shrinkwrap, multi-folder attribution, LC001, and LC002 findings.

Full details: No New Runtime Dependency

Explanation

The pull request does not change package.json. The changed-file inventory contains only source files and a test file, so it adds no entry under dependencies or optionalDependencies and moves no package from devDependencies.

tests/e2e/license-prod-only.test.ts: 1

66-66: Trivial · Functional Correctness · Quick win

Add a second-folder license case that fails when other/ is skipped or filtered wrongly.

The other/ fixture has only an MIT package, so it yields no license findings in any mode. The aggregate assertions still pass if other/ is never license-scanned. They also do not check subfolder, so a finding attributed to the wrong folder passes too. Add a dev-only copyleft package to other/. Then assert that it appears with subfolder: "other" when --prod-only is absent and is excluded when it is present.

As per path instructions, for tests/**: "For each new test, ask whether it would fail if the change it covers were reverted. Flag ... fixtures that cannot exhibit the condition they claim to test."

tests/e2e/license-prod-only.test.ts: 1

79-83: Trivial · Functional Correctness · Low value

Add a production license finding to the other folder.

Production-only scans should still report production license findings in every folder. The multi-folder assertion checks only that other has no findings under --prod-only. That check already catches a missing prodOnly filter in that folder. It does not catch a regression that drops production findings from the second folder, because other has no production finding to drop.

I would add a non-dev copyleft runtime package to other. The test should then expect it in both modes.

Suggested fix

Add the fixture constant near the other constants:

const otherRuntime = "cve-lite-fixture-other-runtime";

Add the package to the other fixture:

-      "other/package.json": { name: "other", dependencies: { [runtime]: "1.0.0" }, devDependencies: { [otherDevelopment]: "1.0.0" } },
+      "other/package.json": { name: "other", dependencies: { [runtime]: "1.0.0", [otherRuntime]: "1.0.0" }, devDependencies: { [otherDevelopment]: "1.0.0" } },
       "other/package-lock.json": { lockfileVersion: 3, packages: {
-        "": { dependencies: { [runtime]: "1.0.0" }, devDependencies: { [otherDevelopment]: "1.0.0" } },
+        "": { dependencies: { [runtime]: "1.0.0", [otherRuntime]: "1.0.0" }, devDependencies: { [otherDevelopment]: "1.0.0" } },
+        [`node_modules/${otherRuntime}`]: { version: "1.0.0", license: "GPL-3.0" },
         [`node_modules/${runtime}`]: { version: "1.0.0", license: "MIT" },

Update the other assertions and the total count:

-      expect(otherFindings).toEqual(prodOnly ? [] : [expect.objectContaining({
-        ruleId: "LC001",
-        package: { name: otherDevelopment, version: "1.0.0" },
-        subfolder: "other",
-      })]);
+      expect(otherFindings).toHaveLength(prodOnly ? 1 : 2);
+      expect(otherFindings).toEqual(expect.arrayContaining([expect.objectContaining({
+        ruleId: "LC001",
+        package: { name: otherRuntime, version: "1.0.0" },
+        subfolder: "other",
+      })]));
+      if (!prodOnly) expect(otherFindings).toEqual(expect.arrayContaining([expect.objectContaining({
+        ruleId: "LC001",
+        package: { name: otherDevelopment, version: "1.0.0" },
+        subfolder: "other",
+      })]));

-    expect(report.licenseFindings).toHaveLength(prodOnly ? 2 : multiFolder ? 5 : 4);
+    expect(report.licenseFindings).toHaveLength(prodOnly ? (multiFolder ? 3 : 2) : multiFolder ? 6 : 4);

Thanks @vianmangal. On the merge with current main the full suite passes, and removing the dev skip fails four of your eight new cases. The pnpm, Yarn and Bun route was already safe, since it only checks packages the scan kept and --prod-only drops dev ones at parse time, so this was the one route left. Approved.
