What is @types/set-cookie-parser?
The @types/set-cookie-parser package provides TypeScript type definitions for the set-cookie-parser package, which is a library for parsing and splitting the Set-Cookie headers into individual cookie objects. It is useful for developers who use TypeScript and want to ensure type safety when working with cookies in HTTP responses.
What are @types/set-cookie-parser's main functionalities?
Parsing Set-Cookie headers
This feature allows you to parse the content of Set-Cookie headers from an HTTP response and convert them into an array of cookie objects with TypeScript type definitions.
import setCookieParser from 'set-cookie-parser';
import { Cookie } from 'set-cookie-parser';
const setCookieHeader = 'sessionToken=abc123; Path=/; HttpOnly';
const cookies: Cookie[] = setCookieParser.parse(setCookieHeader);
Parsing Set-Cookie headers with options
This feature allows you to parse the Set-Cookie headers with additional options, such as mapping the resulting array into an object keyed by cookie names, while maintaining TypeScript type safety.
import setCookieParser from 'set-cookie-parser';
import { Cookie } from 'set-cookie-parser';
const setCookieHeader = 'sessionToken=abc123; Path=/; HttpOnly';
const options = { map: true };
const cookies: { [cookieName: string]: Cookie } = setCookieParser.parse(setCookieHeader, options);
Splitting Set-Cookie headers
This feature allows you to split a Set-Cookie header string or an array of Set-Cookie header strings into an array of individual cookie strings.
import setCookieParser from 'set-cookie-parser';
const setCookieHeaders = [
'sessionToken=abc123; Path=/; HttpOnly',
'userId=12345; Path=/; Secure'
];
const splitCookies: string[] = setCookieParser.splitCookiesString(setCookieHeaders);
Other packages similar to @types/set-cookie-parser
cookie
The 'cookie' package is used for parsing and serializing cookie headers. It provides similar functionality for handling cookies but does not include TypeScript type definitions by default.
tough-cookie
The 'tough-cookie' package is a more robust solution for handling cookies, including parsing, serialization, and cookie jar management. It is a more feature-rich library compared to set-cookie-parser but also does not include TypeScript type definitions by default.
js-cookie
The 'js-cookie' package is a simple, lightweight API for handling cookies in JavaScript. It is primarily designed for use in the browser and offers a fluent interface for cookie manipulation. Unlike set-cookie-parser, it does not focus on parsing Set-Cookie headers from HTTP responses.
