Option to remove `[data-theme]` from being added

[exoRift]

Considering the fact that repainting (by calling paint() again) doesn't update the theme (which is an issue in and of itself),

I would like an option that does not set the data-theme attribute at all so that it can be determined by the Tailwind theme provider what styles to apply to the heatmap.

For now, I have to use this workaround:

).then(() => (cal.current as any).calendarPainter.root?.attr('data-theme', null))

You're right about the theme not being updated when calling paint again. I have created an issue for that.

Regarding the data-theme presence, can you not just override your tailwind theme css, like the docs website is doing ? (https://cal-heatmap.com/assets/css/styles.a42314ed.css)

I can override it, it's just extra work. However, I guess it's not entirely necessary if the updating for the theme is fixed

In case anyone else comes across this and didn't understand the approach above in the context of React:

If you are trying to dynamically adjust the theme when a user toggles dark/light mode on your page, you can do this in a non-standard-react way.

const [themeMode] = useLocalstorageState('theme', 'light');
const prevThemeMode = useRef(themeMode);

  useEffect(() => {
    if (prevThemeMode.current !== themeMode) {
      // there is no built in way to dynamically update the theme, and we don't want to destroy/repaint the entire calendar as that leads to some odd behaviors
      // @ts-ignore
      calInstance.calendarPainter.root?.attr('data-theme', themeMode);
      prevThemeMode.current = themeMode;
    }
  }, [themeMode, prevThemeMode]);
