State in storybook

[daanvdk]

DatePicker and DateRangePicker are both always controlled components. Thus if we want interactive examples in storybook with state we need to somehow keep the state in storybook.

I tried this approach: https://github.com/storybooks/storybook/blob/4b5622a1c1d8d4cc44160b659289f954e8740b13/examples/cra-kitchen-sink/src/stories/force-rerender.stories.js

Which didn't work for me, the component would rerender but somehow the value prop would not be updated.

For now I just added two versions of both components, one without and one with data filled in, but that is obviously not ideal.
