MongoDB-aware serializers (ObjectId/Date/BigInt) and type guards for Cyberscope backends.

mongodb is a peer dependency (^5.6.0 || ^6.0.0 || ^7.0.0) and must be installed by the app. It is never bundled, so instanceof ObjectId uses your copy of the driver.

Exports

| Export | Description | | ----------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------- | | serializeBackend(value, options?) | Converts ObjectId, Date and BigInt to strings and renames _id to id. | | deserializeBackend(value, options?) | Reverses it: id to _id ObjectId, with dateFields, bigIntFields and transform. | | serializeDb(resource, options?) | Encodes the bigInts.keys fields as { _cdt: 104, n, s }; Dates and ObjectIds pass through. | | deserializeDb(resource) | Decodes { _cdt: 104, ... } objects back to BigInt. | | bigIntDataType | The _cdt marker value (104). | | isObject, isBigInt, isDate, isObjectId, isNumber | Type guards. | | Transform, SerializeBackendOptions, DeserializeBackendOptions, SerializeDbOptions | Option types. |

Note: serializeBackend requires options.transform whenever options are passed.
