Use revalidatePath to invalidate the cache for a particular route

For example, to invalidate a specific URL:

import { revalidatePath } from 'next/cache'
 
export async function updatePost(id: string) {
  // Do something...
  // Then revalidate 
  revalidatePath('/blog/post-1')
}

To invalidate a URL pattern:

import { revalidatePath } from 'next/cache'
 
export async function updatePost(id: string) {
  // Do something...
  // Then revalidate 
  revalidatePath('/blog/[slug]')
}

See the revalidatePath API reference to learn more.

You can also use revalidateTag if you need to cache data based on tags.
