Better way of making Redux Ajax actions.

action.js

const REQUEST = 'REQUEST'
const SUCCESS = 'SUCCESS'
const FAILURE = 'FAILURE'

function action(type, payload = {}) {
  return {type, ...payload}
}

const listJDs = {
  request: () => action(ActionTypes.LIST_JDS[REQUEST]),
  success: (jobs, mostUrgent) => action(ActionTypes.LIST_JDS[SUCCESS], {jobs, mostUrgent}),
  failure: (error) => action(ActionTypes.LIST_JDS[FAILURE], {error}),
}

export function getListJDs() {
  return function (dispatch, getState) {
    dispatch(listJDs.request());
    const { auth: { token } } = getState();
    return API.listJDs(token)
      .then((response) => {
        const jobs = getField(response, 'data.data')
        let mostUrgent = null
        jobs.forEach((job) => {
          if (job.applicants.length > 0) {
            if (mostUrgent) {
              if (job.applicants[0].dateReceived < mostUrgent.applicants[0].dateReceived) {
                mostUrgent = job;
              }
            } else {
              mostUrgent = job;
            }
          }
        })
        dispatch(listJDs.success(jobs, mostUrgent));
      })
      .catch((err) => {
        dispatch(listJDs.failure(err));
      });
  };
}
