Hi @majidkarimizadeh. I believe you should follow @jahmaiosullivan’s advice and make your type an Array. In your case try something like the following, instead of changing the middleware.

export function showMessage() {
  return {
    types: [SHOW_MESSAGE, SHOW_MESSAGE_SUCCESS, SHOW_MESSAGE_FAIL],
    promise: (client) => client.get('/posts')
  };
}

Try giving all your fetch actions the same types pattern.

i change some part of clientMiddlware and solve it…

// const [REQUEST, SUCCESS, FAILURE] = types; const REQUEST = ‘REQUEST’; const SUCCESS = ‘SUCCESS’; const FAILURE = ‘FAILURE’; i think i have some problem with my babel and somthing like that 😃

It looks like babel is trying to destructure types in const [REQUEST, SUCCESS, FAILURE] = types; and is failing - check that your types in your action creators are defined & have >=3 elements

type:[REQUEST, SUCCESS, FAILURE],

This is a typo, it should be types: [REQUEST, SUCCESS,FAILURE]
