Serialize this object into JSON.

The object is first converted to a Python dictionary using the :meth:to_dict method and then the dictionary is converted to JSON.

The file parameter controls what to do with the resulting JSON data. It can be:

  • a path (pathlib.Path or string) to a file where to write the data using UTF-8 encoding.

JSON formatting can be configured using optional parameters that are passed directly to the underlying json__ module. Notice that the defaults differ from what json uses.
