Resolving a deferred Q multiple times - node.js

Question

As I know deferred can be resolved only once and also nodejs caches the required module at the first step in order to prevent loading it every single time, but what I want to do is renewing deferred Q object each time I want to resolve/reject a returned value.
This is my server code :
// server.js
app.get('/api/posts', function(req,res,next){
var insta = require('./upRunner'); // this's the main obstacle
insta.returner().then(function(data){
// ....
};
});
and the code for ./upRunner.js is :
// upRunner.js
...
var defer = Q.defer();
upRunner();
function extractor(body) {
var $ = cheerio.load(body), scripts= [];
$('script').each(function(i, elem){
scripts[i] = $(this).text();
});
var str = scripts[6],
newData = JSON.parse(str.substring(str.indexOf("{"), str.lastIndexOf(";"))).entry_data.TagPage[0].tag.media.page_info;
grabber(str);
return newData;
}
function grabber(str) {
newData = JSON.parse(str.substring(str.indexOf("{"), str.lastIndexOf(";"))).entry_data.TagPage[0].tag.top_posts.nodes;
newData.sort(dynamicSort('-date'));
newData.forEach(function(elem,index,array){
if (instaImages.length >= 10) {
defer.resolve(instaImages);
} else {
instaImages.push(elem);
}
});
}
function upRunner(newData){
profilePage = !(tagPage = URL.includes("/tags/") ? true : false);
if (!newData) {
request(URL,{jar:true}, function(err, resp, body){
var $ = cheerio.load(body), scripts= [];
$('script').each(function(i, elem){
scripts[i] = $(this).text();
});
var str = scripts[6],
newData = JSON.parse(str.substring(str.indexOf("{"), str.lastIndexOf(";"))).entry_data.TagPage[0].tag.media.page_info;
upRunner(newData);
});
} else {
if (newData.has_next_page) {
requester(URL, newData.end_cursor).then(function(body){
newData = extractor(body);
upRunner(newData);
});
} else {
console.log('it\'s finished\n');
}
function returner() {
return deferred.promise;
}
exports.returner = returner;
As you see I'm almost renewing upRunner returner deferred promise each time server get /api/posts address, but the problem is the deferred object still return the old resolved value.
There is the grabber function which resolve value, so defer can not be localized in a single function.

Answer 1

Try to initialized deferred value locally to get new resolve value.
function returner() {
var defer= $q.defer();
return deferred.promise;
};
exports.returner = returner;
