Blog (with comments)

This project adds commenting functionality to Next.js blog application using Upstash and Auth0.

The comment box requires Auth0 authentication for users to add new comments. A user can delete their own comment. Also admin user can delete any comment.

Comments are stored in Serverless Redis (Upstash).
