Async Action Creators

createAsyncAction.js

const createAction = actionName => Object.assign(
  payload => ({
    type: actionName,
    payload
  }),
  { type: actionName } // <- Inject `type` attribute to the action func
)

const createAsyncAction = actionName => ({
  request: createAction(actionName + '_REQUEST'),
  success: createAction(actionName + '_SUCCESS'),
  failed: createAction(actionName + '_FAILED'),
})

const getUser = createAsyncAction('GET_USER')
const getPost = createAsyncAction('GET_POST')
// Contoh cara pemakaiannya:
//
// getPost.request(99)
// getPost.success({ id: 99, title: 'Aku ganteng' })
// getPost.failed({ error: 'Maaf, Anda kurang ganteng' })
