refun/native/map-pressed.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.mapPressed = void 0;

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

var _slicedToArray2 = _interopRequireDefault(require("@babel/runtime/helpers/slicedToArray"));

var _react = require("react");

var _tsfn = require("tsfn");

var mapPressed = function mapPressed(props) {
  var origOnPressInRef = (0, _react.useRef)();
  var origOnPressOutRef = (0, _react.useRef)();

  var _useState = (0, _react.useState)(false),
      _useState2 = (0, _slicedToArray2.default)(_useState, 2),
      isPressed = _useState2[0],
      setIsPressed = _useState2[1];

  var onPressInRef = (0, _react.useRef)(_tsfn.NOOP);
  var onPressOutRef = (0, _react.useRef)(_tsfn.NOOP);
  origOnPressInRef.current = props.onPressIn;
  origOnPressOutRef.current = props.onPressOut;

  if (onPressInRef.current === _tsfn.NOOP) {
    onPressInRef.current = function () {
      setIsPressed(true);

      if ((0, _tsfn.isFunction)(origOnPressInRef.current)) {
        origOnPressInRef.current();
      }
    };
  }

  if (onPressOutRef.current === _tsfn.NOOP) {
    onPressOutRef.current = function () {
      setIsPressed(false);

      if ((0, _tsfn.isFunction)(origOnPressOutRef.current)) {
        origOnPressOutRef.current();
      }
    };
  }

  return (0, _extends2.default)({}, props, {
    isPressed: isPressed || Boolean(props.isPressed),
    onPressIn: onPressInRef.current,
    onPressOut: onPressOutRef.current
  });
};

exports.mapPressed = mapPressed;
