CycloneDX JavaScript Library

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

Responsibilities

• 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 a JSON- and an XML-normalizer, 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.

Capabilities

• Enums for the following use cases:
  • AttachmentEncoding
  • ComponentScope
  • ComponentType
  • ExternalReferenceType
  • HashAlgorithm
• Data models for the following use cases:
  • Attachment
  • Bom
  • BomRef, BomRefRepository
  • Component, ComponentRepository
  • ExternalReference, ExternalReferenceRepository
  • HashContent, Hash, HashRepository
  • LicenseExpression, NamedLicense, SpdxLicense, LicenseRepository
  • Metadata
  • OrganizationalContact, OrganizationalContactRepository
  • OrganizationalEntity
  • SWID
  • Tool, ToolRepository
• Factories for the following use cases:
  • Create data models from any license descriptor string
  • Specific to Node.js: create data models from PackageJson-like data structures
• Builders for the following use cases:
  • Specific to Node.js: create deep data models from PackageJson-like data structures
• Implementation of the CycloneDX Specification for the following versions:
  • 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
• 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 plugs/requires/utilizes one of the following optional libraries
    • xmlbuilder2
    • ... to be continued ... (pull requests are welcome)

Installation

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

npm i -S @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
# not supported with yarn

Usage

See extended examples.

As Node.js package

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

const bom = new cdx.Models.Bom()
bom.components.add(
  new cdx.Models.Component(
    cdx.Enums.ComponentType.Library,
    'myComponent'
  )
)

In WebBrowsers

<script src="path-to-this-package/dist.web/lib.js">
    // full Library is available as `CycloneDX_library`, per default
</script>
<script type="application/javascript">
    const cdx = CycloneDX_library

    let bom = new cdx.Models.Bom()
    bom.components.add(
            new cdx.Models.Component(
                    cdx.Enums.ComponentType.Library,
                    'myComponent'
            )
    )
</script>
