Cache invalidation: what do `revalidatePath` and `revalidateTag` do?

Tags
#nextjs#cache#revalidate#server-actions
Back to categoryPractice quiz

Answer

`revalidatePath` invalidates cached data for a specific route path; `revalidateTag` invalidates all cached fetches tagged with that tag. They’re used after mutations (often in Server Actions) to refresh server‑rendered data without a full reload.
