stringEndingWith

stringEndingWith

Matcher for a string that ends with a given suffix.

Matchers are applied through assertObjectMatches, where they narrow the corresponding property type.

Type information that already exists in the calling scope is incorporated.

Usage

import { assertObjectMatches, stringEndingWith } from "@kensio/smartass";

const value: unknown = {
  filename: "report.pdf",
};

assertObjectMatches(value, {
  filename: stringEndingWith(".pdf"),
});

// value is now narrowed to an object with a filename ending in ".pdf"
// {
//   filename: `${string}.pdf`;
// }
