CycloneDX webpack plugin

---

This plugin for webpack creates a CycloneDX Software Bill of Materials (SBoM) containing an aggregate of all bundled dependencies.
This plugin uses the linkages generated by webpack to create a dependency graph which only contain the dependencies that are actually used (after tree-shaking).

Requirements

• Node.js >= 14
• webpack ^5

However, there are older versions of this plugin, that support

• Node.js v8.0.0 or higher
• webpack v4.0.0 or higher

Installing

npm i -D @cyclonedx/webpack-plugin
yarn add -D @cyclonedx/webpack-plugin

Usage

new CycloneDxWebpackPlugin(options?: object)

Options & Configuration

Name	Type	Default	Description
specVersion	{string} one of: "1.2", "1.3", "1.4", "1.5", "1.6"	"1.4"	Which version of CycloneDX-spec to use. Supported values depend on the installed dependency CycloneDX-javascript-library.
reproducibleResults	{boolean}	false	Whether to go the extra mile and make the output reproducible. Reproducibility might result in loss of time- and random-based-values.
validateResults	{boolean}	true	Whether to validate the BOM result. Validation is skipped, if requirements not met. Requires transitive optional dependencies.
outputLocation	{string}	"./cyclonedx"	Path to write the output to. The path is relative to webpack's overall output path.
includeWellknown	{boolean}	true	Whether to write the Wellknowns.
wellknownLocation	{string}	"./.well-known"	Path to write the Wellknowns to. The path is relative to webpack's overall output path.
rootComponentAutodetect	{boolean}	true	Whether to try auto-detection of the RootComponent. Tries to find the nearest package.json and build a CycloneDX component from it, so it can be assigned to bom.metadata.component.
rootComponentType	{string}	"application"	Set the RootComponent's type. See the list of valid values. Supported values depend on CycloneDX-javascript-library's enum ComponentType.
rootComponentName	optional {string}	undefined	If rootComponentAutodetect is disabled, then this value is assumed as the "name" of the package.json.
rootComponentVersion	optional {string}	undefined	If rootComponentAutodetect is disabled, then this value is assumed as the "version" of the package.json.
collectEvidence	{boolean}	false	Whether to collect (license) evidence and attach them to the resulting SBOM.

Example

In your webpack config add the CycloneDX plugin:

const { CycloneDxWebpackPlugin } = require('@cyclonedx/webpack-plugin');

/** @type {import('@cyclonedx/webpack-plugin').CycloneDxWebpackPluginOptions} */
const cycloneDxWebpackPluginOptions = {
  specVersion: '1.6',
  outputLocation: './bom'
}

module.exports = {
  // ...
  plugins: [
    new CycloneDxWebpackPlugin(cycloneDxWebpackPluginOptions)
  ]
}

See extended examples.

Support for IETF /.well-known/sbom

The CycloneDX webpack plugin supports placing the CycloneDX SBOM in a pre-defined location, specifically in /.well-known/sbom. This option is enabled by default. The behavior can be changed by overriding the values of includeWellknown and wellknownLocation.
See draft-ietf-opsawg-sbom-access for more information on the specification, currently an IETF draft.

In your webpack config add the CycloneDX plugin:

const { CycloneDxWebpackPlugin } = require('@cyclonedx/webpack-plugin');

/** @type {import('@cyclonedx/webpack-plugin').CycloneDxWebpackPluginOptions} */
const cycloneDxWebpackPluginOptions = {
  includeWellknown: true,
  wellknownLocation: './.well-known'
}

module.exports = {
  // ...
  plugins: [
    new CycloneDxWebpackPlugin(cycloneDxWebpackPluginOptions)
  ]
}

Use with Angular

Angular uses webpack under the hood. Therefore, it is possible to integrate this plugin by utilizing @angular-builders/custom-webpack.
See an example here: integration with Angular17/webpack5.

Use with React

React uses webpack under the hood. Therefore, it is possible to integrate this plugin.
See an example here: integration with React18/webpack5.

Internals

This webpack plugin utilizes the CycloneDX library to generate the actual data structures.

Besides the class CycloneDxWebpackPlugin and the interface CycloneDxWebpackPluginOptions,
this webpack plugin does not expose any additional public API or classes - all code is intended to be internal and might change without any notice during version upgrades.
