| Yarn | yarn.lock | ✓ | Excluded | ✓ | ✓ |
| pnpm | pnpm-lock.yaml | ✓ | Excluded | ✓ | - |

These may be enabled or disabled depending on the target. See here for the detail.
Package managers
Trivy parses your files generated by package managers in filesystem/repository scanning.
Tip
Please make sure your lock file is up-to-date after modifying package.json.
npm
Trivy parses package-lock.json.
To identify licenses, you need to download dependencies to node_modules beforehand.
Trivy analyzes node_modules for licenses.
By default, Trivy doesn't report development dependencies. Use the --include-dev-deps flag to include them.
Yarn
Trivy parses yarn.lock, which doesn't contain information about development dependencies.
Trivy also uses package.json file to handle aliases.
To exclude devDependencies and allow aliases, package.json also needs to be present next to yarn.lock.
Trivy analyzes .yarn (Yarn 2+) or node_modules (Yarn Classic) folder next to the yarn.lock file to detect licenses.
By default, Trivy doesn't report development dependencies. Use the --include-dev-deps flag to include them.
pnpm
Trivy parses pnpm-lock.yaml, then finds production dependencies and builds a tree of dependencies with vulnerabilities.
Bun
Trivy supports scanning yarn.lock files generated by Bun. You can use the command bun install -y to generate a Yarn-compatible yarn.lock.
Note
bun.lockb is not supported.
Packages
Trivy parses the manifest files of installed packages in container image scanning and so on.
package.json
Trivy searches for package.json files under node_modules and identifies installed packages.
It only extracts package names, versions and licenses for those packages.
