Our Journey with Caching

Frontend performance can be hard to get right. Even in highly optimized apps, the most common culprit by far is client-server waterfalls. When introducing Next.js App Router, we knew we wanted to solve this issue. To do that, we needed to move client-server REST fetches to the server using React Server Components in a single roundtrip. This meant the server had to sometimes be dynamic, sacrificing the great initial loading performance of Jamstack. We built partial prerendering to solve this tradeoff and have the best of both worlds.
