Overview

NextGuard demonstrates how to create a secure authentication system entirely within Next.js, eliminating the need for external backends. This tutorial guides you through implementing protected routes with middleware, building login/logout flows with API routes, and managing secure HTTP-only cookies for session management. You'll learn to intercept requests, redirect unauthorized users, and validate credentials—all while following modern security practices. Perfect for developers looking to streamline their stack while maintaining robust authentication. The project uses TypeScript and provides a solid foundation for real-world applications requiring user authentication.
