Yet another store using redux. (Inspired by vuex and dva)

import { getNestedState } from './util';

function normalizeMap(map) {
  return Array.isArray(map) ? map.map(function (key) {
    return {
      key: key,
      val: key
    };
  }) : Object.keys(map).map(function (key) {
    return {
      key: key,
      val: map[key]
    };
  });
}

function normalizeNamespace(fn) {
  return function (namespace, map) {
    if (typeof namespace !== 'string') {
      map = namespace;
      namespace = '';
    } else if (namespace.charAt(namespace.length - 1) !== '/') {
      namespace += '/';
    }

    return fn(namespace, map);
  };
}

export var mapState = normalizeNamespace(function (namespace, states) {
  return function (state) {
    var res = {};
    normalizeMap(states).forEach(function (_ref) {
      var key = _ref.key,
          val = _ref.val;
      var path = (namespace + val).split('/');
      res[key] = getNestedState(state, path);
    });
    return res;
  };
});
export var mapActions = normalizeNamespace(function (namespace, actions) {
  return function (dispatch) {
    var res = {};
    normalizeMap(actions).forEach(function (_ref2) {
      var key = _ref2.key,
          val = _ref2.val;
      var type = namespace + val;

      res[key] = function (payload) {
        return dispatch({
          type: type,
          payload: payload
        });
      };
    });
    return res;
  };
});
