computedAsync Type documentation¶

<T, R> (options: ComputedAsyncOptions<T, R>) => Signal<T>¶

Function

Computed value, but async. This exists because the resource() API is not suitable. During loading, the value changes to undefined . The proposed solution of resource snapshots and a withPreviousValue() function that uses resourceFromSnapshots() isn't suitable either because it's experimental.
Returns readonly signal

Parameters
the options options: `ComputedAsyncOptions`<`T`, `R`>¶
