Open Serverless Auth Toolkit for Next.js

This package, `open-serverless-auth` (current version 0.2.0), provides a toolkit for integrating Next.js applications with a centralized Open Serverless Auth hub. It includes an Edge Middleware for protecting downstream applications by redirecting unauthorized users, and Server Action/Component helpers like `getUserData()` to retrieve authenticated user information. Its primary differentiator is simplifying centralized authentication architecture across subdomains using cross-subdomain cookies, abstracting away complex login UI development on client apps. It's designed to work seamlessly with Next.js App Router and assumes a peer dependency on `next` version 13 or higher. The current version suggests it's relatively new, likely in active development with potentially frequent updates, although a specific release cadence isn't stated. The core value proposition is enabling easy setup of a centralized authentication system, offloading authentication concerns from individual client applications.
