everysk-orjson is a high-performance JSON library for Python, forked from orjson. It provides fast serialization and deserialization, with additional features for handling big integers and special floating-point values.

• Big Integer Support
  Parse large integers without loss of precision using the OPT_BIG_INTEGER option.

  import orjson
  
  result = orjson.dumps(100000000000000000001, option=orjson.OPT_BIG_INTEGER)
  print(result) # b'100000000000000000001'
  
  result = orjson.loads(b'100000000000000000001', option=orjson.OPT_BIG_INTEGER)
  print(result)  # 100000000000000000001

• NaN as Null
  Convert NaN values to null during deserialization with the OPT_NAN_AS_NULL option.

  import orjson
  
  result = orjson.loads('{"x": nan}', option=orjson.OPT_NAN_AS_NULL)
  print(result)  # {'x': None}

pip install everysk-orjson

everysk-orjson is a drop-in replacement for orjson. Simply import and use the additional options as needed.
