Info on flags

• The --output flag specifies where to output/save the exported categories. Several notes on this flag:

  • If the file specified already exists, it will be overwritten.

  • The default location for status report logging is the standard output.

  • If no output path is specified, the exported categories will be logged to the standard output as a result, status reports will be logged to a category-exporter.log file in the current directory.

• The where flag specifies an optional (where) query predicate to be included in the request. This predicate should be wrapped in single quotes ('single quoted predicate'). More info on predicates here

JS

For more direct usage, it is possible to use this module directly:

import CategoryExporter from '@commercetools/category-exporter'
import fs from 'fs'

const options = {
    apiConfig: {
      apiUrl: 'https://api.europe-west1.gcp.commercetools.com'
      host: 'https://auth.europe-west1.gcp.commercetools.com'
      project_key: 'PROJECT_KEY',
      credentials: {
        clientId: '*********',
        clientSecret: '*********'
      }
    },
    accessToken: '123456yuhgfdwegh675412wefb4rgb',
    predicate: 'key="my-desired-key"'
  }
}
const logger = {
  error: console.error,
  warn: console.warn,
  info: console.log,
  debug: console.debug,
}

const categoryExporter = new CategoryExporter(options, logger)

// Register error listener
outputStream.on('error', errorHandler)

outputStream.on('finish', () => console.log('done with export'))

categoryExporter.run(outputStream)
