Advanced Topics: Authentication and Database Integration</h2> <p>Building modern web applications often involves managing user identities (authentication) and storing/retrieving data (database integration). Next.js, especially with the App Router, provides powerful and secure ways to handle these concerns. This chapter will guide you through implementing robust authentication and integrating with a database using popular tools and best practices.</p> <h3 id="71-authentication-in-nextjs">7.1 Authentication in Next.js</h3> <p>Authentication in Next.js has evolved significantly with the App Router.
