从ahooks里面抽取的一些在rn项目里可以使用的hooks。提高开发效率

'use strict';

var react = require('react');

var useLoadingDelayPlugin = function (fetchInstance, _a) {
    var loadingDelay = _a.loadingDelay, ready = _a.ready;
    var timerRef = react.useRef();
    if (!loadingDelay)
        return {};

        if (timerRef.current) {
            clearTimeout(timerRef.current);
        }
    };
    return {
        onBefore: function () {
            cancelTimeout();
            // Two cases:
            // 1. ready === undefined
            // 2. ready === true
            if (ready !== false) {
                timerRef.current = setTimeout(function () {
                    fetchInstance.setState({
