tapAsync

tapAsync<A>(fn, options?): (a) => A

Defined in: Composition/tap.ts:142

Returns

Example

const user = { id: 1 };
const saveToDatabase = async (u: typeof user) => {};
const logError = (err: unknown) => console.error(err);

pipe(
  user,
  tapAsync(async (u) => {
    await saveToDatabase(u);
  }, { onError: (err) => logError(err) })
);
