# Node.js
Trivy supports four types of Node.js package managers: `npm`, `Yarn`, `pnpm` and `Bun`[^1].
The following scanners are supported.
| Artifact | SBOM | Vulnerability | License |
|----------|:----:|:-------------:|:-------:|
| npm | ✓ | ✓ | ✓ |
| Yarn | ✓ | ✓ | ✓ |
| pnpm | ✓ | ✓ | ✓ |
| Bun | ✓ | ✓ | ✓ |
The following table provides an outline of the features Trivy offers.
| Package manager | File | Transitive dependencies | Dev dependencies | [Dependency graph][dependency-graph] | Position |
|:---------------:|-------------------|:-----------------------:|:---------------------------------:|:------------------------------------:|:--------:|
| npm | package-lock.json | ✓ | [Excluded](#npm) | ✓ | ✓ |
| Yarn | yarn.lock | ✓ | [Excluded](#yarn) | ✓ | ✓ |
| pnpm | pnpm-lock.yaml | ✓ | [Excluded](#lock-file-v9-version) | ✓ | - |
| Bun | bun.lock | ✓ | [Excluded](#bun) | ✓ | ✓ |
In addition, Trivy scans installed packages with `package.json`.
| File | Dependency graph | Position | License |
|--------------|:----------------:|:--------:|:-------:|
| package.json | - | - | ✅ |
These may be enabled or disabled depending on the target.
See [here](./index.md) 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`.
Trivy also analyzes additional files to gather more information about the detected dependencies.
- package.json
- node_modules/**
#### Package relationships
`yarn.lock` files don't contain information about package relationships, such as direct or indirect dependencies.
To enrich this information, Trivy parses the `package.json` file located next to the `yarn.lock` file as well as workspace `package.json` files.
By default, Trivy doesn't report development dependencies.
Use the `--include-dev-deps` flag to include them in the results.
#### Development dependencies
`yarn.lock` files don't contain information about package groups, such as production and development dependencies.
To identify dev dependencies and support [aliases][yarn-aliases], Trivy parses the `package.json` file located next to the `yarn.lock` file as well as workspace `package.json` files.
#### Licenses
Trivy analyzes the `.yarn` directory (for Yarn 2+) or the `node_modules` directory (for Yarn Classic) located next to the `yarn.lock` file to detect licenses.
### pnpm
Trivy parses `pnpm-lock.yaml`, then finds production dependencies and builds a [tree][dependency-graph] of dependencies with vulnerabilities.
To identify licenses, you need to download dependencies to `node_modules` beforehand. Trivy analyzes `node_modules` for licenses.
#### lock file v9 version
Trivy supports `Dev` field for `pnpm-lock.yaml` v9 or later. Use the `--include-dev-deps` flag to include the developer's dependencies in the result.
### Bun
Trivy also supports scanning `bun.lock` file generated by [Bun](https://bun.sh/blog/bun-lock-text-lockfile).
You can use Bun v1.2 which uses this file as default or use `bun install --save-text-lockfile` in Bun v1.1.39 to generate it.
For previous Bun versions you can use the command `bun install -y` to generate a Yarn-compatible `yarn.lock` and then scan it with Trivy.
#### Development dependencies
`bun.lock` contains information about package groups, such as production and development dependencies. By default, Trivy doesn't report development dependencies. Use the `--include-dev-deps` flag to include them.
!!! 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.
