Is it possible to revalidate the first call from useSWRInfinite?

[philmetzger]

I am using useSWRInfinite like so:

const { data, size, setSize, mutate } = useSWRInfinite('/api/posts?page=X', fetchFromAuthedApi, {
    revalidateOnFocus: true,
    revalidateAll: true,
    revalidateFirstPage: true,
  })

where page X changes for the next pages etc.

Now I have a list of "posts". If a user created a new post, i would like to calls the first api endpoint, e.g. '/api/posts?page=1' to get the new post and put it in the list.

I tried using mutate from import { mutate } from 'swr' and then calling it like this after a post is created:
mutate('/api/posts?page=1')

But nothing seems to happen. I expect the new post to popup in the list.

How could I achieve this?

I also cant use mutate from useSWRInfinite because the data from the api is different to the data from the create endpoint. (i could reformat the data, but would rather not)
