json-advanced 0.13.0

This Python package provides an extended JSON encoder class, `JSONSerializer`, that enables encoding of complex Python data types such as `datetime.datetime`, `datetime.date`, `datetime.time`, `bytes` and `uuid`. It also supports objects that have a `to_json` method, allowing for customizable JSON encoding.

Extended JSON Encoder

The json-advanced is Python package provides an extended JSON encoder class, JSONSerializer, that enables encoding of complex Python data types such as datetime.datetime, datetime.date, datetime.time, bytes and uuid. It also supports objects that have a to_json method, allowing for customizable JSON encoding.

Features

• Datetime Handling: Automatically converts datetime.datetime, datetime.date, and datetime.time objects to their string representation.
• UUID Encoding: Encodes uuid objects as uuid strings.
• Bytes Encoding: Encodes bytes objects as base64 strings, prefixed with b64:.
• Custom Object Support: Encodes any object that has a to_json method by calling that method.

Installation

You can install the package directly from source:

pip install json-advanced

Usage

To use the JSONSerializer in your project, you need to import it and use it with the standard json module's dump or dumps functions:

import json
import datetime
import uuid

from json_advanced.json_encoder import JSONSerializer

# Example object containing various complex data types
data = {
    "now": datetime.datetime.now(),
    "today": datetime.date.today(),
    "time": datetime.datetime.now().time(),
    "bytes_data": b"example bytes",
    "uuid": uuid.uuid4(),
}

# Serialize the object to a JSON string
json_string = json.dumps(data, cls=JSONSerializer)
print(json_string)

Extending the Serializer

If you have custom types that you want to serialize, you can extend JSONSerializer by overriding the default method. Ensure you call super().default(obj) for types you do not handle:

class MyCustomSerializer(JSONSerializer):
    def default(self, obj):
        if isinstance(obj, MyCustomType):
            return obj.custom_serialize()
        return super().default(obj)
