fetch caching

In the Next.js App Router fetch is cached by default. You opt out with cache: 'no-store'.

A widely shared tutorial says every fetch in the App Router is cached and reused automatically so you must set cache: 'no-store' to get fresh data. That described Next.js 13 to 14 behavior. It is still repeated as current advice in many posts. The current official default is the opposite.

In the Next.js App Router fetch is not cached by default. You opt in with cache: 'force-cache'.

Same question with opposite answers about the current default. The official docs say fetch is not cached by default while a popular tutorial says it is cached by default. The official source is current so it wins.
