assertStringNotEmpty

Assert that a string has at least one character, with type-narrowing.

Note that this counts UTF-16 code units, not Unicode grapheme clusters.

Usage

import { assertStringNotEmpty } from "@kensio/smartass";

const value: unknown = "admin";

assertStringNotEmpty(value);

// value is now narrowed to a non-empty string
