Introducing Next.js SDK v4 (GA)

We are excited to announce the next major version of Next.js SDK. With the introduction of nextjs-auth0 v4, we now support Next.js 15 and React 19, allowing developers to leverage the latest features and improvements in both frameworks. This compatibility not only enhances the development experience but also ensures that applications can take full advantage of performance optimizations. This updated SDK features a simplified architecture and is edge-compatible by default, enhancing performance and flexibility for developers.

What’s new:

• Middleware-Based Authentication: Improved compatibility and reduced maintenance by moving to middleware-based handlers.
• Enhanced Security: Switched to encrypted cookies and removed outdated cookie logic.
• Resolved State Mismatch Issues: Fixed long-standing issues reported by the community.
• Improved Session Management: Implemented rolling sessions and eliminated cookie chunking.
• Improved Hooks and Helpers: Introduced useUser(), getAccessToken(), and getSession() for easier data fetching and session handling.
• Stateful Sessions with Custom Databases: Support for "Bring Your Own Database" (BYODB).
• Compatibility with Next.js 15, Turbopack, and React 19
• Simplified architecture, API, and configuration options
