refun/node/map-handlers-factory.js

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

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

var _react = require("react");

var _tsfn = require("tsfn");

const mapHandlersFactory = getHandlers => props => {
  const actualHandlers = (0, _react.useRef)(_tsfn.EMPTY_OBJECT);
  const propsRef = (0, _react.useRef)(props);
  propsRef.current = props;

  if (actualHandlers.current === _tsfn.EMPTY_OBJECT) {
    const handlers = getHandlers(props);
    actualHandlers.current = (0, _tsfn.getObjectKeys)(handlers).reduce((result, key) => {
      result[key] = (...args) => handlers[key](propsRef.current)(...args);

      return result;
    }, {});
  }

  return { ...props,
    ...actualHandlers.current
  };
};

exports.mapHandlersFactory = mapHandlersFactory;
