CSRF Sync

CSRF Sync is a utility package designed to provide robust stateful Cross-Site Request Forgery (CSRF) protection for Express applications, utilizing the Synchroniser Token Pattern. Developed in response to the deprecation of `csurf` and the perceived complexity or limited scope of alternative solutions, `csrf-sync` (current stable version 4.2.1) aims for a targeted and simplified implementation. It requires a server-side session management middleware like `express-session` to store tokens. The library focuses on providing the essential components for CSRF protection without imposing a full solution, allowing developers to integrate it flexibly. It is actively maintained with regular updates and follows a clear versioning strategy, with significant changes typically highlighted in major version bumps.
