delete

• delete(deleteReferences?, deepDeleteReferences?): Promise<number>

• Delete this document from the database client that it lives in.

  If you're using a databaseless-document instance, this method will throw an error!

  Parameters

  • OptionaldeleteReferences: boolean

    Similar to deepDeleteReferences, but you can pick one or the other. If true, all referenced documents will also delete themselves. If those referenced documents also reference additional documents, those documents are unaffected and may become orphaned.
  • OptionaldeepDeleteReferences: boolean

    Similar to deleteReferences, but you can pick one or the other. If true, all referenced documents will also delete themselves and recursively delete any documents that they also reference.

  Returns Promise<number>

  Number of documents deleted. You'd want this to be just 1. Other functions may use this number to create a greater tally (eg. a database client's findAndDeleteMany method).
