): ReadonlyRecord<K, V>;

Defined in: packages/common/src/Object.ts:189

Creates an object from key-value pairs, preserving branded key types.

The inverse of objectToEntries. Use when you need type-safe reconstruction of objects with branded keys.

Example

import {
  assertEqual,
  assertType,
  objectFromEntries,
  type Brand,
  type ReadonlyRecord,
} from "@evolu/common";

type UserId = string & Brand<"UserId">;
const entries: ReadonlyArray<[UserId, string]> = [["u1" as UserId, "Alice"]];
const users = objectFromEntries(entries);

assertType<ReadonlyRecord<UserId, string>, typeof users>();
assertEqual(users, { u1: "Alice" });
