Engage your site visitors with live updates using PlanetScale, Ably, Next.js, and Prisma

In this tutorial, we learn how to implement live commenting in a blog using Next.js, Ably, PlanetScale, Prisma, and Vercel. The process involves setting up the tech stack, creating an API endpoint for authentication with Ably, implementing pub/sub messaging, connecting the comment form, testing the functionality, creating a database with PlanetScale, installing and configuring the Prisma ORM, reading and writing comments to the database, and deploying the application to Vercel.
