Create a collection document from an object that may contain metadata fields.

Description

If the following metadata fields are included, they populate the document data Object field:

  • data.

Otherwise, the data field isn’t instantiated.

  id: 12345,
  coll: "Person",
  name: "John Doe",
  email: "john.doe@example.com",
  address: {
    street: "123 Main St",
    city: "San Francisco",
    state: "CA",
    postalCode: "12345",
    country: "United States"
  }
})
{
  id: "412999820218728960",
  coll: Customer,
  ts: Time("2099-07-30T22:04:39.400Z"),
  cart: null,
  orders: "hdW...",
  name: "John Doe",
  email: "john.doe@example.com",
  address: {
    street: "123 Main St",
    city: "San Francisco",
    state: "CA",
    postalCode: "12345",
    country: "United States"
  },
  data: {
    coll: "Person",
    id: 12345
  }
}

createData() treats any metadata field as a document field and nests it in the document’s data property.
