Core functionality of CycloneDX for JavaScript (Node.js or WebBrowsers), written in TypeScript and compiled for the target.

• Provide a general purpose JavaScript-implementation of CycloneDX for Node.js and WebBrowsers.
• Provide typing for said implementation, so developers and dev-tools can rely on it.
• Provide data models to work with CycloneDX.
• Provide JSON- and XML-normalizers, that...
  • supports all shipped data models.
  • respects any injected CycloneDX Specification and generates valid output according to it.
  • can be configured to generate reproducible/deterministic output.
  • can prepare data structures for JSON- and XML-serialization.
• Serialization:
  • Provide a universal JSON-serializer for all target environments.
  • Provide an XML-serializer for all target environments.
  • Support the downstream implementation of custom XML-serializers tailored to specific environments
    by providing an abstract base class that takes care of normalization and BomRef-discrimination.
    This is done, because there is no universal XML support in JavaScript.
• Provide formal JSON- and XML-validators according to CycloneDX Specification. (currently for Node.js only)

• Factories for the following use cases:
  • Create data models from any license descriptor string
  • Create PackageURL from Component data models
  • Specific to Node.js: create data models from PackageJson-like data structures and derived data
• Builders for the following use cases:
  • Specific to Node.js: create deep data models Tool or Component from PackageJson-like data structures
• Implementation of the CycloneDX Specification for the following versions:
  • 1.6
  • 1.5
  • 1.4
  • 1.3
  • 1.2
• Normalizers that convert data models to JSON structures
• Normalizers that convert data models to XML structures
• Universal serializer that converts Bom data models to JSON string
• Specific Serializer that converts Bom data models to XML string:
  • Specific to WebBrowsers: implementation utilizes browser-specific document generators and printers.
  • Specific to Node.js: implementation utilizes optional dependencies as described below
• Formal validators for JSON string and XML string (currently for Node.js only)
  Requires optional dependencies as described below

This package and the build results are available for npm, pnpm and yarn:

npm i -S @cyclonedx/cyclonedx-library
pnpm add @cyclonedx/cyclonedx-library
yarn add @cyclonedx/cyclonedx-library

You can install the package from source, which will build automatically on installation:

npm i -S github:CycloneDX/cyclonedx-javascript-library
pnpm add github:CycloneDX/cyclonedx-javascript-library
yarn add @cyclonedx/cyclonedx-library@github:CycloneDX/cyclonedx-javascript-library # only with yarn-2

Some dependencies are optional. See the shipped package.json for version constraints.

• Serialization to XML on Node.js requires any of:
  • xmlbuilder2
• Validation of JSON on Node.js requires all of:
  • ajv
  • ajv-formats
  • ajv-formats-draft2019
• Validation of XML on Node.js requires all of:
  • libxmljs2
  • the system might need to meet the requirements for node-gyp, in certain cases.

See extended examples.

const CDX = require('@cyclonedx/cyclonedx-library')

const bom = new CDX.Models.Bom()
bom.metadata.component = new CDX.Models.Component(
  CDX.Enums.ComponentType.Application,
  'MyProject'
)
const componentA = new CDX.Models.Component(
  CDX.Enums.ComponentType.Library,
  'myComponentA',
)
bom.components.add(componentA)
bom.metadata.component.dependencies.add(componentA.bomRef)

<script src="path-to-this-package/dist.web/lib.js"></script>

We ship annotated type definitions, so that your IDE and tools may pick up the documentation when you use this library downstream.

There are also pre-rendered documentations hosted on readthedocs.
