refun/native/map-handlers-factory.js

A collection of React Hook-enabled functions that compose harmoniously with each other. Similar to `recompose`, but:

var _interopRequireDefault = require("@babel/runtime/helpers/interopRequireDefault");

Object.defineProperty(exports, "__esModule", {
  value: true
});
exports.mapHandlersFactory = void 0;

var _extends2 = _interopRequireDefault(require("@babel/runtime/helpers/extends"));

var _react = require("react");

var _tsfn = require("tsfn");

var mapHandlersFactory = function mapHandlersFactory(getHandlers) {
  return function (props) {
    var actualHandlers = (0, _react.useRef)(_tsfn.EMPTY_OBJECT);
    var propsRef = (0, _react.useRef)(props);
    propsRef.current = props;

    if (actualHandlers.current === _tsfn.EMPTY_OBJECT) {
      var handlers = getHandlers(props);
      actualHandlers.current = (0, _tsfn.getObjectKeys)(handlers).reduce(function (result, key) {
        result[key] = function () {
          return handlers[key](propsRef.current).apply(void 0, arguments);
        };

        return result;
      }, {});
    }

    return (0, _extends2.default)({}, props, actualHandlers.current);
  };
};

exports.mapHandlersFactory = mapHandlersFactory;
