anyResult - API reference

API reference › @evolu/common › Result › anyResult

function anyResult<T>(
  results: T,
): Result<InferOk<T[number]>, InferErr<T[number]>>;

Defined in: packages/common/src/Result.ts:1391

Returns the first successful Result.

If all results fail, returns the last error.

Requires a non-empty array — there's no "first success" with zero participants. Use isNonEmptyArray to guard.

Example

import {
  anyResult,
  assertOk,
  assertType,
  err,
  ok,
  type Result,
  type Typed,
} from "@evolu/common";

const getCachedPrice = (): Result<number, CacheMissError> =>
  err({ type: "CacheMiss" });

interface CacheMissError extends Typed<"CacheMiss"> {}

const number = anyResult([getCachedPrice(), ok(42)]);
assertType<Result<number, CacheMissError>, typeof number>();
assertOk(number, 42);
