Is there an API that can refresh a specific atom?

Is there an API that can refresh a specific atom, something similar to react-query queryClient.invalidateQueries('todos')?

Hi, if it's a sync atom, refreshing means reset, like setting the default value, right?
Or, is it about async atom? If so, more use case description would be helpful.

No not reset, by the way, the concept of resettable, https://docs.pmnd.rs/jotai/guides/resettable, why is this needed when every atom comes anyway with a setter which you can use to reset the state?

What I really meant is async data when you fetch something from an API.

It's just handy. Not necessary.

Okay, async or not, the derived atom can't be reset.
In such use cases, I'd create a new atom, or we can now store a promise as an atom value.
Hm, if you just need to refetch, you could add another dependency.

const version = atom(0)
const data = atom(async (get) => {
  get(version)
  const response = await fetch(...)
  return response.json()
})
