## What it is
A Node.js module for getting and setting HTTP(S) cookies, with optional signing to prevent tampering via Keygrip. It works with the built-in Node.js HTTP library or as Connect/Express middleware.

## Use cases
- set and get http cookies in a node.js server
- sign cookies to prevent tampering
- use cookies as express middleware
- read cookies lazily in a node http handler
- rotate cookie signing keys
- secure httponly cookies by default

## When to choose
- you need signed, tamper-proof cookies in Node.js without a full framework
- you want lightweight, lazy cookie parsing on raw Node.js HTTP
- you need Express/Connect middleware for cookie handling with key rotation

## When to avoid
- you are not on Node.js
- you only need simple unsigned cookies and prefer built-in or framework-provided cookie parsing
- you need session storage or server-side session management rather than plain cookies
