json-encoder 0.4.2

json encoder using singledispatch pattern instead of JSONEncoder class overwrites

• json encoder using singledispatch pattern instead of JSONEncoder class overwrites.

• No more json.dumps(data, csl=MyJSONEncoder) everywhere.

• 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 …

Installation

$ pip install json-encoder

Quick start

• Use “json_encoder.json” instead of default python json:

  from json_encoder import json
  
  result = json.dumps(json)

Configuration

• Chose json implementation:

  # simplejson library is uses as default json implementation
  # if simplejson isn't installed then python json implementation is used
  # to use other json implementation globally, do:
  
  import ujson as json
  from json_encoder import use_json_library
  
  use_json_library(json)

• To change json implementation for concrete call do:

  from json_encoder import json
  import simplejson
  
  result = json.dumps(json, 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_decimal(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 2.x only
