refun/native/map-safe-timeout.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.mapSafeTimeout = exports.mapSafeTimeoutFactory = void 0;

var _defineProperty2 = _interopRequireDefault(require("@babel/runtime/helpers/defineProperty"));

var _extends3 = _interopRequireDefault(require("@babel/runtime/helpers/extends"));

var _react = require("react");

var _tsfn = require("tsfn");

var mapSafeTimeoutFactory = function mapSafeTimeoutFactory(setTimeoutFn, clearTimeoutFn) {
  return function (propName) {
    return function (props) {
      var timerIdsRef = (0, _react.useRef)(_tsfn.EMPTY_OBJECT);
      var setSafeTimeoutRef = (0, _react.useRef)();
      var useEffectFnRef = (0, _react.useRef)();

      if (setSafeTimeoutRef.current === _tsfn.UNDEFINED) {
        timerIdsRef.current = new Set();

        setSafeTimeoutRef.current = function (cb, delay) {
          if (timerIdsRef.current === _tsfn.EMPTY_OBJECT) {
            return _tsfn.NOOP;
          }

          var timerId = setTimeoutFn(function () {
            timerIdsRef.current.delete(timerId);
            cb();
          }, delay);
          timerIdsRef.current.add(timerId);
          return function () {
            clearTimeoutFn(timerId);
            timerIdsRef.current.delete(timerId);
          };
        };

        useEffectFnRef.current = function () {
          return function () {
            timerIdsRef.current.forEach(function (id) {
              return clearTimeoutFn(id);
            });
            timerIdsRef.current.clear();
            timerIdsRef.current = _tsfn.EMPTY_OBJECT;

    };
  };
};
