Make any type JSON-serializable

Project description

Build status

Make any type JSON-serializable.

A Python module which makes json.dumps work with several builtin and stdlib types. A hook for registering any custom type is also provided.

Installing

Simply install alljson with pip or add it to your project dependencies:

pip install alljson

Supported types

After installing, the following types are JSON-serializable:

  • generators
  • set and frozenset
  • dict item/key/value iterators and views
  • datetime.date and datetime.datetime (as strings in ISO format)
  • uuid.UUID
  • decimal.Decimal (serialized as string in order to preserve precision)
  • reversed results

In addition to these, the following Python 3 types are supported:

  • map, filter, range iterators
  • enum.Enum
  • pathlib.Path
  • types.MappingProxyType
  • classes implementing Sequence and Mapping abc interfaces

Registering custom types

In order to register a new type, use alljson.register_encoder(type, encoder_function). encoder_function should take object of given type as the only parameter and return a simple JSON-serializable Python value (such as dict or str).

For example:

import arrow
import alljson

alljson.register_encoder(arrow.Arrow, arrow.Arrow.isoformat)
