refun/native/on-change.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.onChange = void 0;

var _react = require("react");

var _tsfn = require("tsfn");

var _utils = require("./utils");

var onChange = function onChange(getFn, watchKeys) {
  return function (props) {
    var prevPropsRef = (0, _react.useRef)(_tsfn.EMPTY_OBJECT);

    if (prevPropsRef.current === _tsfn.EMPTY_OBJECT || !(0, _utils.shallowEqualByKeys)(prevPropsRef.current, props, watchKeys)) {
      getFn(props);
    }

    prevPropsRef.current = props;
    return props;
  };
};

exports.onChange = onChange;
