@td-design/rn-hooks/lib/module/useRequest/utils/cachePromise.js

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

var cachePromise = new Map();
var getCachePromise = function (cacheKey) {
    return cachePromise.get(cacheKey);
};
var setCachePromise = function (cacheKey, promise) {
    // Should cache the same promise, cannot be promise.finally
    // Because the promise.finally will change the reference of the promise
    cachePromise.set(cacheKey, promise);
    // no use promise.finally for compatibility
    promise
        .then(function (res) {
        cachePromise.delete(cacheKey);
        return res;
    })
        .catch(function () {
        cachePromise.delete(cacheKey);
    });
};

export { getCachePromise, setCachePromise };
