This demo uses the Pages Router. The traditional way of developing apps with Next.js. It can feel more straightforward to use. Especially if you're used to writing apps with vanilla React. However, it can get complicated when you start to use some features like caching, SSR, streaming, etc.

The page includes dynamic content fetched through an API, which takes about one second to load. With the Pages Router, data fetching logic needs to be handled client-side. For the App Router, data can be fetched directly within the server component, simplifying the code a bit.
