Haaremy SSO Auth SDK

The official Haaremy SSO Authentication SDK provides a comprehensive solution for integrating Haaremy's Single Sign-On system into JavaScript applications. It encapsulates token handling, login/logout flows, BroadcastChannel-based tab synchronization, and offers specific integrations for React and Next.js. Currently at version 2.0.0, this SDK is actively maintained with a focus on security and developer experience. Key differentiators include its 'zero localStorage' approach (tokens are memory-only), proactive token refresh, server-side replay detection for token families, and efficient offline JWT validation using JWKS caching with Ed25519 signatures. It offers distinct entrypoints for vanilla JS/framework-agnostic core logic, React hooks and components, and Next.js middleware/server-side helpers, making it adaptable to various application architectures.
