    • sort:string - MongoDB property sort key. Default is '-createdAt'

• store({model, data}) - You can create a doc and store it to MongoDB.

  • model - Mongoose model.

  • populateOptions - Mongoose population object/string.

• update({model, where, data}) - updates the first document that matches where. data is the object where you want to update the data.
