    obj: t.Any,
    fp: t.IO[str],
    kwargs: t.Any
) - > None

Serialize data as JSON and write to a file. If flask.current_app is available, it will use its app.json.dump() method, otherwise it will use json.dump.

Parameters

Name	Type	Description
obj	t.Any	The data object to be serialized into JSON format.
fp	t.IO[str]	A file-like object opened for writing text, which should use UTF-8 encoding to ensure valid JSON output.
kwargs	t.Any	Additional keyword arguments passed to the underlying JSON dump implementation.

Returns

Type	Description
None	Nothing is returned; the serialized data is written directly to the provided file object.
