Custom Datetime JSON Serializer

CDJS (Custom Datetime JSON Serializer)

cdjs is an extension for orjson to serialize datetime in a custom way.

By default orjson serializes datetime according to RFC 3339 format which sometimes may not suit. orjson provides a mean to process datetime using custom serializer (via OPT_PASSTHROUGH_DATETIME flag and via default=custom_datetime_serializer). Serializers implemented in Python are usually not fast enough, that's the reason behind implementation of the custom datetime serializer written in Rust to gain optimal speed.

Example

import datetime
import orjson
from cdjs import serialize_date

mydate = datetime.datetime(2021, 1, 1, hour=0, minute=4, second=36, microsecond=123000)
orjson.dumps(mydate, option=orjson.OPT_PASSTHROUGH_DATETIME, default=serialize_date)
