useAsyncValue: useAsyncValue

In reactRouter: 'React Router' for 'shiny' Apps and 'Quarto'

useAsyncValue

Description

https://api.reactrouter.com/v7/functions/react-router.useAsyncValue.html

Usage

useAsyncValue(
  into = NULL,
  as = "children",
  selector = NULL,
  render = NULL,
  ...
)

Arguments

into	A component (HTML tag or shiny.react-based element) that will receive the hook data as the specified prop.
as	Character. The name of the component's prop to inject the hook data into (by default "children" for text display, "rows" for a data grid, "value" for an input).
selector	Character. Optional key to extract from the hook data object. If NULL (the default), the entire data is passed. Dotted paths like "summary.title" navigate nested objects.
render	Optional JS function (value) => ReactNode used in place of into/as. Mirrors the native React Router pattern for cases where a single prop is not expressive enough (e.g. JS("v => `${v.first} ${v.last}`")).
...	Additional props to pass to the component.

Details

Calls the useAsyncValue() hook and injects the resolved value (or a selector from it) as a prop of the into component. Must be rendered inside an Await that has been called in children mode (no into / render on Await) – the hook reads the value resolved by the closest <Await> ancestor.
