An attempt to generify redux ajax thunk generation. this generates the action types and the action creator for you, but you'd still have to write your reducer. Worthwhile?

redux boilerplate reduction: ajax thunks

function createAsyncFeature(name, url) {
  const actionTypes = {
    name + "_INVALIDATED": name + "_INVALIDATED",
    name + "_RETRIEVED": name + "_RETRIEVED",
    name + "_FAILED": name + "_FAILED"
  }

  const createInvalidatingAction() {
    return {
      type: actionTypes[name + "_INVALIDATED"],
      meta: {
        timestamp: Date.now()
      }
    }
  }

  const createRetrievalAction(json) {
    return {
      type: actionTypes[name + "_RETRIEVED"],
      payload: json,
      meta: {
        timestamp: Date.now()
      }
    }
  }

  const createErrorAction(err) {
    return {
      type: actionTypes[name + "_FAILED"],
      payload: err,
      error: true,
      meta: {
        timestamp: Date.now()
      }
    }
  }

  const actionCreator = function() {
    return function(dispatch) {
      dispatch(createInvalidatingAction());

      return fetch(url, {headers: {'Content-Type': 'application/JSON'}})
        .then(response => response.json())
        .then(json => dispatch(createRetrievalAction(json)))
        .catch(err => dispatch(createErrorAction(err)))
    }
  }

  return {
    name,
    actionTypes,
    actionCreator
  }
}
