━━━ Usage ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$ yarn cyclonedx

━━━ Options ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  --spec-version #0        Which version of CycloneDX to use.
                           (choices: 1.6, 1.5, 1.4, 1.3, 1.2, default: 1.5)
  --output-format #0       Which output format to use.
                           (choices: JSON, XML, default: JSON)
  --output-file #0         Path to the output file.
                           Set to "-" to write to STDOUT.
                           (default: write to STDOUT)
  --production,--prod      Exclude development dependencies.
                           (default: true if the NODE_ENV environment variable is set to "production", otherwise false)
  --mc-type #0             Type of the main component.
                           (choices: application, library, firmware, default: application)
  --short-PURLs            Omit all qualifiers from PackageURLs.
                           This causes information loss in trade-off shorter PURLs, which might improve ingesting these strings.
  --output-reproducible    Whether to go the extra mile and make the output reproducible.
                           This might result in loss of time- and random-based values.
  --verbose,-v             Increase the verbosity of messages.
                           Use multiple times to increase the verbosity even more.

Internals

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

This tool 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. However, the CLI is stable - you may call it programmatically like:

const { execFileSync } = require('node:child_process')
const { constants: { MAX_LENGTH: BUFFER_MAX_LENGTH } } = require('node:buffer')
const sbom = JSON.parse(execFileSync(process.execPath, [
    '.../path/to/this/package/bin/cyclonedx-yarn-cli.js',
    '--output-format', 'JSON',
    '--output-file', '-'
    // additional CLI args
  ], {stdio: ['ignore', 'pipe', 'ignore'], encoding: 'buffer', maxBuffer: BUFFER_MAX_LENGTH }))
