Interface DeserializeOptions

allows the buffer to be larger than the parsed BSON object

return BSON regular expressions as BSONRegExp instances.

cache evaluated functions for reuse.

use a crc32 code for caching, otherwise use the string of the function.

Deprecated

this option to use the crc32 function never worked as intended due to the fact that the crc32 function itself was never implemented.

evaluate functions in the BSON document scoped to the object deserialized.

allow to specify if there what fields we wish to return as unserialized raw buffer.

Offset into buffer to begin reading document from

when deserializing a Binary will return it as a node.js Buffer instance.

when deserializing a Long will fit it into a Number if it's smaller than 53 bits

when deserializing will promote BSON values to their Node.js closest equivalent types.

Allows for opt-out utf-8 validation for all keys or specified keys. Must be all true or all false.

Example

// disables validation on all keys
 validation: { utf8: false }

// enables validation only on specified keys a, b, and c
 validation: { utf8: { a: true, b: true, c: true } }

 // disables validation only on specified keys a, b
 validation: { utf8: { a: false, b: false } }
