Скачать или смотреть Next.js Caching Deep Dive + Visual Walkthrough

Hey everyone!, 

In this video, we’re diving deep into how caching works in Next.js. I’ll walk you through the four main caching layers: Request Memoization, the Data Cache, Full Route Cache, and the client-side Router Cache. Each one plays a different role in performance, and by the end, you’ll understand exactly how they work and when to use them.

All code examples from the video are on GitHub:

This channel is all about making frontend and AI topics easier to learn. I believe education should be free, so I’ll keep making videos like this to share what I learn and provide as much value as possible.

I also mention the “stale-while-revalidate” pattern — it’s a key part of how data caching works behind the scenes. If you want to dig deeper:
