Overview

Whilst looking about to see if anyone had proposed a __json__ protocol for Python, I found this article and it struck me as so simple and obviously right.

So, I decided to provide a lib to make it easier for everyone.

Usage

Just pass json_default.default as the default function when calling json.dump(s).

import json

from json_default import default

...

return json.dumps(mydata, default=default)

If you have more types you want to define serialisation for, just add them:

from json_default import default


@default.register(mytype)
def _(obj):
    ...
