Next.js and Next-Auth V5: Guide to Social Logins(OAuth)

This tutorial explains authentication and authorization in Next.js applications using NextAuth.js (version 5). The process involves setting up a Next.js project and installing NextAuth.js. Environment variables, including a secret key, are configured for security. A basic login form is created with buttons for Google and GitHub authentication. NextAuth.js handles the authentication process via server actions. Google OAuth integration requires obtaining a client ID and secret from the Google Cloud Console. These credentials are added to the .env.local file and configured within the NextAuth.js providers array. The tutorial demonstrates creating a callback route for handling OAuth redirects. Finally, the application is tested to verify successful Google login functionality. The GitHub login process would follow a similar pattern, requiring separate configuration steps. The complete code is available on GitHub.
