SameSite=None Cookie Compatibility Utility

This package provides a utility function (`isSameSiteNoneCompatible`) and an Express.js middleware (`shouldSendSameSiteNone`) to address specific browser compatibility issues with the `SameSite=None; Secure` cookie attribute. Introduced around Chrome 80 in February 2020, the `SameSite=None; Secure` setting is required for cross-site cookies, but some older browsers (notably Chrome 51-66, certain Safari versions, and UC Browser) handle this attribute incorrectly, potentially leading to cookies being rejected or mismanaged. This library detects these incompatible user agents based on a known list from Chromium, allowing developers to dynamically adjust cookie settings to ensure functionality across a broader range of clients. The current stable version is 2.0.5, with recent updates focused on bug fixes and improved TypeScript declarations. It offers a crucial compatibility layer for web applications relying on cross-site cookie functionality, saving developers from maintaining an exhaustive list of incompatible clients themselves.
