asVoid

Discards the resolved value of a Promise, returning a Promise<void> that resolves once the original settles.

Useful when you await a promise only for its side effect and want the result type to reflect that nothing meaningful is produced — for example when an API expects a Promise<void> or when narrowing a value-bearing promise to keep call sites from accidentally depending on the resolved value. A rejection of the original promise still propagates.

Signature

export declare const asVoid: <T>(promise: Promise<T>) => Promise<void>

Example

import { PromiseX } from "@nunofyobiz/effect-extras"

const run = async (): Promise<void> => {
  const result = await PromiseX.asVoid(Promise.resolve(42))
  assert.deepStrictEqual(result, undefined)
}

void run()
