Callbacks

Hook callbacks are a way to perform custom logic based on the current action execution status. You can provide them to the three hooks in the utils object, which is the second argument. All of them are optional:

const action = useAction(testAction, {
  onExecute: ({ input }) => {},
  onSuccess: ({ data, input }) => {},
  onError: ({ error, input }) => {},
  onSettled: ({ result, input }) => {},
});

Here is the full list of callbacks, with their behavior explained. All of them are optional and have return type void or Promise<void> (async or non-async functions with no return):

Name	HookActionStatus state
onExecute?	"executing"
onSuccess?	"hasSucceeded"
onError?	"hasErrored"
onSettled?	"hasSucceeded" or "hasErrored" (after onSuccess or onError call)
