如何更改 react-jsonschema-forms 中类型/格式的默认小部件

Question

I want react-jsonschema-forms (rjsf) to render a custom widget for each {type: 'string', format: 'duration'} field and an other one for {type: 'number', format: 'currency'} .

With react-jsonschema-forms (rjsf) as I can overwrite/exchange the Widgets used by the form as documented :

    const widgets = {'TextWidget': MyFanycTextWidget}
    return <Form {...props} widgets={widgets} />

But since TextWidget is used for many type/format combinations, this is too much.

I could overwrite the widgets used by using ui:schema , but for that I would have to new the shape of the jsonschemata used in advance (which I do not).

Internally rjsf conatains a niche type/format mapping in widgetMap .

Is there an way to overwrite / monkeypatch / extend this? Or an other aproach?
