json-encoder 0.4.4
json encoder uses singledispatch pattern instead of JSONEncoder class overwrites

json-encoder
=======================

* json encoder uses `singledispatch pattern`_ instead of JSONEncoder class overwrites.

* No more *json.dumps(data, cls=MyJSONEncoder)* everywhere.

* Comes with default serialization for time, date, datetime, UUID and Decimal

* Easy to use, easy to change serialization behaviour

* Not tight to any json implementation *json, simplejson, ujson* ...

* It parse json float numbers into Decimal objects to prevent python float precision issues.

    :target: https://pypi.python.org/pypi/json-encoder

Installation
------------

.. code-block:: bash

    $ pip install json-encoder

Quick start
-----------

* Use "json_encoder.json" instead of default python json::

    from json_encoder import json

    result = json.dumps(data)

Configuration
-------------

* Chose json implementation::

    # simplejson library is used as default json implementation if present
    # otherwise standard python json implementation is used
    # to use other json implementation globally, do:

    import ujson
    from json_encoder import use_json_library

    use_json_library(ujson)

* To change json implementation for concrete call do::

    from json_encoder import json
    import simplejson

    result = json.dumps(data, json=simplejson)

* To make your object JSON serializable do::

    # example how to make python fraction object json serializable

    from fractions import Fraction
    from json_encoder.encoder import json_encoder

    @json_encoder.register(Fraction)
    def encode_fraction(obj):
        return '{}/{}'.format(obj.numerator, obj.denominator)

* To overwrite JSON serializer behaviour defined in json_encoder.encoder::

    from uuid import UUID
    from six import text_type
    from json_encoder.encoder import json_encoder

    @json_encoder.register(UUID)
    def encode_uuid(obj):
        return text_type(obj).replace('-', '')

Requirements
------------

* `singledispatch`_ >= 3.4.0.3 for python version < 3.4 only
