Exploring ORM and CMS Integration in Next.js, Performance Improvements, and Educational Materials

Tim joins Sam to talk about his work on the new app router in Next.js 13. He explains how the app router leverages Server Components and React’s new cache API to bring a new level of composability to server-side code, how Server Actions are being designed to enable partial revalidation in a single round trip to the server, and how to think about UI updates as a result of server-side state changes.

Topics include:

• 1:21:43 - Caching layers
• 1:30:53 - Current focus on stability, performance, education, and TurboPack
