getCookies

function

function getCookies(headers: Headers): Partial<Record<string, string>>

Parse cookies of a header

The returned object has a null prototype (so it does not inherit from Object.prototype — properties like toString or hasOwnProperty will be undefined rather than the inherited methods). The return type is Partial<Record<string, string>> to reflect that arbitrary key access may yield undefined when no cookie of that name was set.

headers: Headers

The headers instance to get cookies from

Returns

Object with cookie names as keys (null-prototype). Values are typed as string | undefined so missing-key access is caught at compile time.

import { getCookies } from "@ende/http/cookie";

const headers = new Headers();
headers.set("Cookie", "full=of; tasty=chocolate");

const cookies = getCookies(headers);
assertEquals(cookies.full, "of");
assertEquals(cookies.tasty, "chocolate");
assertEquals(cookies.missing, undefined);
