tough-cookie

tough-cookie is a robust, RFC6265-compliant implementation of HTTP cookies and a CookieJar for Node.js, designed for developers who need precise, standards-based cookie management in server-side applications. It handles cookie parsing, storage, serialization, and domain/path matching, making it essential for building reliable HTTP clients or servers that must correctly manage session state. Its strict adherence to the specification and support for features like cookie prefixes and expiration logic make it a trusted, low-level dependency for many popular Node.js libraries.
