Trying to understand state management

Thanks @MaartenBreddels! I'm just trying to figure out how best to structure a solara app and I think that aligns with what I'm envisaging - only use globals for application-wide state and otherwise inject reactive variables into the components 🤔

Trying to understand state management

Is the recommended way to inject reactive variables into reusable components from the outer scope? e.g.

@solara.component
def SliderComponent(value: int | Reactive[int] = 0) -> None:
    if not isinstance(value, Reactive):
        slider_value = solara.use_reactive(value)
    else:
        slider_value = value
    solara.IntSlider('', slider_value.value, min=0, max=50)

@solara.component
def MyApp():
    slider1 = solara.use_reactive(21)
    slider2 = solara.use_reactive(42)
    SliderComponent(slider1)
    SliderComponent(slider2)
    SomeComponentThatUsesTheValuesOfAllSliders(
        slider1, slider2,
    )

@solara.component
def SliderComponent(value: int | Reactive[int] = 0) -> None:
    if not isinstance(value, Reactive):
        slider_value = solara.use_reactive(value)
    else:
        slider_value = value
    solara.IntSlider('', slider_value.value, min=0, max=50)

@solara.component
def MyApp():
    slider1 = solara.use_reactive(21)
    slider2 = solara.use_reactive(42)
    SliderComponent(slider1)
    SliderComponent(slider2)
    SomeComponentThatUsesTheValuesOfAllSliders(
        slider1, slider2,
    )
