Build a Comment Section for your NextJS blog using Redis and NextAuth

The tutorial provides a comprehensive guide on building a comment section for a blog using a tech stack that includes NextJS 13, NextAuth for authentication, Upstash Redis for storing comments, and SWR for caching and revalidation. It begins with setting up NextAuth to prevent unauthorized users from posting comments, utilizing GitHub OAuth for authentication, and using the SessionProvider to manage session states across the application. The guide then walks through creating a Redis database with Upstash, setting up API endpoints for comment creation, retrieval, and deletion using Redis Lists, and integrating these server-side capabilities with the client side using fetch requests and the SWR library for data management. The tutorial concludes by implementing a custom useComment hook to handle comment submissions and deletions, ensuring a fully functional comment section.
