Next.js Middleware Auth demonstrates how to layer authentication logic into the App Router without relying on third-party services. It blends lightweight session cookies with JWT signatures so you can protect both server and client routes while keeping deployment options open.
Highlights
- Secure middleware that checks sessions before rendering protected routes or hitting API handlers
- JWT issuing and verification helpers with rotating secrets and refresh token support
- Example login, registration, forgot password, and protected dashboard flows built with React Server Components
- Type-safe server actions for performing auth mutations on the backend without exposing client secrets
- Unit and integration tests that cover middleware edge cases and token lifecycle scenarios
