npm i @sec-ant/set-cookie-parser

Usage

This package provides three main functions: parse, parseString, and splitCookiesString.

parse

The parse function takes a string or an array of strings representing cookies and an options object of type ParseOptions. It returns an array of objects representing the parsed cookies if the map property of the options object is false or not provided. If the map property is true, it returns an object with the cookie names as keys and the parsed cookies as values.

import { parse, ParseOptions } from "@sec-ant/set-cookie-parser";

const cookies = "name=value; expires=Wed, 21 Oct 2021 07:28:00 GMT; secure";
const options: ParseOptions = {
  decodeValues: true,
  map: true,
};
const parsedCookies = parse(cookies, options);
console.log(parsedCookies);

parseString

The parseString function takes a string representing a single cookie and an optional configuration object of type ParseStringOptions. It returns an object representing the parsed cookie.

import { parseString, ParseStringOptions } from "@sec-ant/set-cookie-parser";

const cookie = "name=value; expires=Wed, 21 Oct 2021 07:28:00 GMT; secure";
const options: ParseStringOptions = {
  decodeValues: true,
};
const parsedCookie = parseString(cookie, options);
console.log(parsedCookie);

splitCookiesString

The splitCookiesString function takes a string representing multiple cookies separated by commas. It returns an array of strings representing the individual cookies.

import { splitCookiesString } from "@sec-ant/set-cookie-parser";

const cookies =
  "name1=value1; expires=Wed, 21 Oct 2021 07:28:00 GMT; secure, name2=value2; expires=Wed, 21 Oct 2021 07:28:00 GMT; secure";
const splitCookies = splitCookiesString(cookies);
console.log(splitCookies);

Configuration

The parse and parseString functions accept an optional configuration object as the second parameter. The configuration object can have the following properties:

• decodeValues: A boolean indicating whether to decode the cookie values using decodeURIComponent. Defaults to true.
• map: A boolean indicating whether to return an object with the cookie names as keys and the parsed cookies as values. Only applicable to the parse function. Defaults to false.
