What is cookiejar?
The npm package 'cookiejar' is a utility for handling web cookies in Node.js. It allows for the creation, retrieval, manipulation, and deletion of cookies, making it easier to manage client-side state information across web requests.
What are cookiejar's main functionalities?
Create and manage cookies
This feature allows the creation and management of cookies. The code sample demonstrates how to create a new cookie jar and set a cookie with an expiration date.
const CookieJar = require('cookiejar');
const jar = new CookieJar();
const cookie = jar.setCookie('key=value; expires=Wed, 09 Jun 2021 10:18:14 GMT');
Retrieve cookies
This feature enables the retrieval of cookies based on specific criteria such as domain and path. The code shows how to retrieve a cookie from the jar that matches the specified domain and path.
const CookieJar = require('cookiejar');
const jar = new CookieJar();
jar.setCookie('key=value; path=/; domain=example.com');
const cookie = jar.getCookie('key', {domain: 'example.com', path: '/'});
Parse and serialize cookies
This feature deals with parsing cookies from request headers and serializing them for HTTP headers. The code illustrates how to serialize all cookies in the jar for use in an HTTP request.
const CookieJar = require('cookiejar');
const CookieAccessInfo = CookieJar.CookieAccessInfo;
const jar = new CookieJar();
jar.setCookie('key=value; path=/; domain=example.com');
const serializedCookies = jar.getCookies(CookieAccessInfo.All).toValueString();
Other packages similar to cookiejar
tough-cookie
Tough-cookie is another popular npm package for handling cookies in Node.js. It offers a robust API for cookie manipulation and parsing, including asynchronous cookie storage, which cookiejar does not support. Tough-cookie is often preferred for more complex cookie handling tasks.
cookie
The 'cookie' npm package is simpler and more lightweight compared to cookiejar. It focuses primarily on parsing and serializing cookie headers, without the additional management features like a cookie jar. This makes it suitable for applications that require minimal cookie handling capabilities.
