Elasticsearch js how to upsert a document

Question

I would like to do a upsert for a document. Is it currently possible to do that via nodejs elasticsearch API?

https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/current/api-reference.html

I looked through the API, and I could only see an upsert option for update.

Does that mean currently there aren't any way for me to upsert a document?

Thanks

Set the doc_as_upsert parameter to true when calling the update method to upsert a document.

const response = await client.update({
  index: 'myindex',
  type: 'mytype',
  id: '1',
  body: {
    doc: {
      title: 'Updated'
    },
    doc_as_upsert: true
  }
});
