In this tutorial, we learn how to build a Next.js frontend application with GitHub authentication using Strapi. We cover setting up Next.js GitHub OAuth with Strapi, creating a secure, user-friendly authentication system, and implementing social login in an application. The steps include setting up the Next.js frontend, configuring Strapi, handling the authentication flow with Next.js middleware for route protection, and testing the setup. By following these steps, we have a secure and efficient authentication system that enhances user experience by leveraging GitHub OAuth with Strapi for social login.
