In this step-by-step tutorial, we dive deep into implementing authentication in a Next.js application using Firebase as our identity provider. We'll explore the benefits of using third-party authentication services like Firebase over building custom authentication systems. Learn how to set up Firebase in your Next.js app, handle user sign-in with Google, manage user sessions, and protect routes with middleware. Whether you're a beginner or looking to enhance your authentication flow, this video covers everything you need to know to get started with Firebase authentication in Next.js.
It's worth mentioning that starting Next.js 15.2, the Node runtime will be available in middlewares(experimental feature), so you don't need to make a separate API to validate the token.
