The postBulkDocs function allows to insert, update or delete multiple documents with one call.

To delete, call it with a _deleted flag in each document.

For example, if you have these three docs (you only need their _id and _rev to delete):

var docs = [{
  _id: '0007241142412418284',
  _rev: '2-4567766',
  _deleted: true
},
{
  _id: '000459458904590453',
  _rev: '3-59695945',
  _deleted: true
},
{
  _id: '0004590650650678',
  _rev: '2-796865867967',
  _deleted: true
}]

..then as long as they each have a _deleted:true flag in the body, then they will be deleted when you call the postBulkDocs function:

await service.postBulkDocs({
  db: 'mydb',
  bulkDocs: {"docs":docs}
})

There are more examples in the API documentation.
