There's a strong belief in the community that it's not possible to work with relational databases inside of Jamstack applications, but frameworks like Next.js and others support both static generation and server-side rendering, allowing for hybrid apps that use static site generation for most pages and server-side rendering for others. A new Next.js starter app with authentication, Prisma, and PlanetScale has been released, which allows developers to create a MySQL-compatible database within seconds using PlanetScale's serverless database platform. The starter app uses NextAuth.js for built-in authentication and Prisma to interact with the database, making it easy to get started with authentication and data management in Jamstack applications. Additionally, PlanetScale supports database branching, allowing developers to isolate their development environment from production, and non-blocking schema changes, which enables zero downtime while deploying schema changes. The starter app is available on Netlify's Jamstack Templates page.
