    System properties:

    The following properties can be set (e.g. using JVM -D options).

    • reactivemongo.api.bson.bufferSizeBytes (integer; default: 96): Number of bytes used as initial size when allocating a new buffer.
    • reactivemongo.api.bson.document.strict (boolean; default: false): Flag to enable strict reading of document (filter duplicate fields, see BSONDocument.asStrict).

trait ReadDefaultValues extends Default

Considering a class property with a default value, when reading the class from BSON if there is no BSON value corresponding to the property, then the default value is used.

import reactivemongo.api.bson.{
  BSONDocument, BSONDocumentReader, Macros, MacroOptions
}

case class Foo(id: Int, title: String = "default")

val reader: BSONDocumentReader[Foo] =
  Macros.using[MacroOptions.ReadDefaultValues].reader[Foo]

reader.readTry(BSONDocument("id" -> 1))
// => Success: Foo(id = 1, title = "default")
