If success - reset state (promise based toaster)

[dorin-js]

Can anybody advise how to reset form's state controlled inputs on success? with simple toast i can do just .then(...) and i'm good, but there is a delay, no loading information. And now i have no idea how to setState("") if success, if error then leave them.

toast.promise(
        fetch('/api/post', {
          method: 'POST',
          headers: {
            'Content-Type': 'application/json',
          },
          body: JSON.stringify(body),
        }),
        {
          loading: 'Saving...',
          success: <b>Published!</b>,
          error: <b>Could not save.</b>,
        }
      )
      //  .then(() => {
      //    setTitle('')
      //    setContent('')
      //  })
      //  .catch((error) => {
      //    notifyNotOk()
      //    console.log(error)
      //  })
