For loops breaks when using await

I have a problem when using await in a for loop. Every time it hits the await funtion it executes it fine, but it stops loping through the rest of the array that is looping through. I'm using nodejs with axios to send http request to a restAPI. The function that is in the api is big. So I thought maby that is the problem but it wasn't. Also the api uses its own await functions to, but that wasn't the problem either(As far as I know).
Here is my code for the request
var files = await globPromise("assets/series/**/*.json");
var json = null;
var file = null;
var series = [];
for (i = 0; i < files.length; i++) {
file = files[i];
var raw = fs.readFileSync(file);
json = JSON.parse(raw);
if (json.type === "series") {
try {
var userId = null;
if (req.user == null) {
userId = req.query.userid;
} else {
userId = req.user.id;
}
const response = await axios.get("http://" + host + "/series/info/" + json.id + "?userid=" + userId);
series.push(JSON.parse(response.data));
} catch (error) {
console.log(error);
series.push(json);
}
}
}
res.json(JSON.stringify(series));
});
And also the api side:
app.get('/series/info/:id', async(req, res) => {
var files = await globPromise("assets/series/**/*.json");
var json = null;
var file = null;
for (i = 0; i < files.length; i++) {
file = files[i];
var raw = fs.readFileSync(file);
json = JSON.parse(raw);
if (json.type === "series" && json.id === req.params.id) {
break;
}
json = null;
}
let path = pathFs.dirname(file) + "/";
try {
var seriesFiles = await fsPromise.readdir(path);
var latestWatchedVideo = null;
var latestWatchedTime = null;
var latestWatchTime = null;
var latestWatchDuration = null;
var seasonCount = 0;
var seasons = [];
for (i = 0; i < seriesFiles.length; i++) {
seriesFile = seriesFiles[i];
if (fs.lstatSync(path + "/" + seriesFile).isDirectory()) {
if (!seriesFile.startsWith("s")) {
continue;
}
seasonCount++;
try {
var videoFiles = await fsPromise.readdir(path + "/" + seriesFile + "/");
var videos = [];
for (let i = 0; i < videoFiles.length; i++) {
const video = videoFiles[i];
if (video.endsWith(".json")) {
var rawVideo = fs.readFileSync(path + "/" + seriesFile + "/" + video);
videoJson = JSON.parse(rawVideo);
const query = util.promisify(con.query).bind(con);
var userId = null;
if (req.user == null) {
userId = req.query.userid;
} else {
userId = req.user.id;
}
var results = await query(`SELECT * FROM watched WHERE video_id = "${videoJson.id}" AND user_id = "${userId}"`);
if (results.length > 0) {
var updated = JSON.parse(JSON.stringify(results[0].updated));
var duration = JSON.parse(JSON.stringify(results[0].duration));
var time = JSON.parse(JSON.stringify(results[0].time));
if (latestWatchedVideo == null) {
latestWatchedVideo = videoJson.id;
latestWatchedTime = updated;
latestWatchTime = time;
latestWatchDuration = duration;
} else {
if (latestWatchedTime < updated) {
latestWatchedVideo = videoJson.id;
latestWatchedTime = updated;
latestWatchTime = time;
latestWatchDuration = duration;
}
}
}
videos.push(videoJson);
}
}
function compare(a, b) {
if (a.episode < b.episode) {
return -1;
}
if (a.episode > b.episode) {
return 1;
}
return 0;
}
videos.sort(compare);
seasons.push({
season: seasonCount,
title: seriesFile.replace("s" + seasonCount, ""),
videos: videos
});
} catch (error) {
console.log(error);
}
}
}
json.seasonCount = seasonCount;
json.seasons = seasons;
json.latestWatchDuration = latestWatchDuration;
json.latestWatchTime = latestWatchTime;
json.latestWatchedVideo = latestWatchedVideo;
json.latestWatchedTime = latestWatchedTime;
res.json(JSON.stringify(json));
} catch (error) {
console.log(error);
}
});
Is there something (important) about await and async that I've missed?
Edit: my problem is that is loops fine through the first item and the await is working fine too, but it stops the loop and executes the next lines of code like there are no other items in my array.
Solved: I tried using the for/of and it works now. I don't know whats is so different between de default for and this one but it works!

Threads module giving error of channel closed

I am using the npm xlsx (lib/parserScripts/readExcel.js)
and threads module to read a large excel file.
This works fine for the first time but if I simultaneously upload another large file then I get an error
Error: channel closed
at ChildProcess.target.send (internal/child_process.js:554:16)
at Worker.send (/app/node_modules/threads/lib/worker.node/worker.js:108:16)...
This is maybe due to the previous threads are still processing /have not been killed hence when a new pool is made for another request the previous threads are still busy processing.
How to solve this? Do I have to manually terminate the threads in the below piece of code? If so then how?
index.js

This works fine for the first time but if I simultaneously upload another large file then I get an error.
you should upload a different file name like a final01.xlsx and then rename it to final.xlsx
The reason being when you upload file the readfile cant finish as writing a file locks the file and change content.
If upload file means you are simultaneously reading another large file in node.js code ignore my comment.

The issue is because of the older version module of threads. Updating to the new version and using the updated API which is not event-based can solve the purpose.
https://github.com/andywer/threads.js/issues/164
However, if you want to correct the event-based code(from older version) this is what you need to do (kill the threads after the event gets completed).
const Threads = require('threads');
const Pool = Threads.Pool;
module.exports = class JobManager {
static bufferedJob(pathToScript, params, callback){
let workerPool = new Pool();
workerPool
.run(pathToScript)
.send(params)
.on('done', (result, input) => {
console.log(`Worker Job done: ${pathToScript} `);
callback(null, result);
workerPool.killAll();
workerPool = null ;
})
.on('error', (job, error) => {
console.log(`Error in executing Worker Job: ${pathToScript}`);
callback(job || error);
workerPool.killAll();
workerPool = null ;
}).on('abort', (job, error)=>{
console.log(`Abort Worker Job: ${pathToScript}, Error : ${error}`);
callback(job || error);
workerPool.killAll();
workerPool = null ;
}).on('finished', ()=>{
console.log('Everything done, shutting down the thread pool.');
workerPool.killAll();
});
}
}

Linkedin Autoconnect With User role

I am trying to fix this script to automatically connect people you may know on Linkedin based on User roles (CEO e.t.c), Can someone help me fix this, Below is my code; I have tried the script on almost all browsers, Somebody help fix this.
var userRole = [
"CEO",
"CIO"
];
var inviter = {} || inviter;
inviter.userList = [];
inviter.className = 'button-secondary-small';
inviter.refresh = function () {
window.scrollTo(0, document.body.scrollHeight);
window.scrollTo(document.body.scrollHeight, 0);
window.scrollTo(0, document.body.scrollHeight);
};
inviter.initiate = function()
{
inviter.refresh();
var connectBtns = $(".button-secondary-small:visible");
//
if (connectBtns == null) {var connectBtns = inviter.initiate();}
return connectBtns;
};
inviter.invite = function () {
var connectBtns = inviter.initiate();
var buttonLength = connectBtns.length;
for (var i = 0; i < buttonLength; i++) {
if (connectBtns != null && connectBtns[i] != null) {inviter.handleRepeat(connectBtns[i]);}
//if there is a connect button and there is at least one that has not been pushed, repeat
if (i == buttonLength - 1) {
console.log("done: " + i);
inviter.refresh();
}
}
};
inviter.handleRepeat = function(button)
{
var nameValue = button.children[1].textContent
var name = nameValue.replace(/^\s\s*/, '').replace(/\s\s*$/, '');
function hasRole(role){
for(var i = 0; i < role.length; i++) {
// cannot read children of undefined
var position = button.parentNode.parentNode.children[1].children[1].children[0].children[3].textContent;
var formatedPosition = position.replace(/^\s\s*/, '').replace(/\s\s*$/, '');
var hasRole = formatedPosition.indexOf(role[i]) == -1 ? false : true;
console.log('Has role: ' + role[i] + ' -> ' + hasRole);
if (hasRole) {
return hasRole;
}
}
return false;
}
if(inviter.arrayContains(name))
{
console.log("canceled");
var cancel = button.parentNode.parentNode.children[0];
cancel.click();
}
else if (hasRole(userRole) == false) {
console.log("cancel");
var cancel = button.parentNode.parentNode.children[0];
cancel.click();
}
else if (button.textContent.indexOf("Connect")<0){
console.log("skipped");
inviter.userList.push(name); // it's likely that this person didn't join linkedin in the meantime, so we'll ignore them
var cancel = button.parentNode.parentNode.children[0];
cancel.click();
}
else {
console.log("added");
inviter.userList.push(name);
button.click();
}
};
inviter.arrayContains = function(item)
{
return (inviter.userList.indexOf(item) > -1);
};
inviter.usersJson = {};
inviter.loadResult = function()
{
var retrievedObject = localStorage.getItem('inviterList');
var temp = JSON.stringify(retrievedObject);
inviter.userList = JSON.parse(temp);
};
inviter.saveResult = function()
{
inviter.usersJson = JSON.stringify(inviter.userList);
localStorage.setItem('inviterList', inviter.usersJson);
};
setInterval(function () { inviter.invite(); }, 5000);
`
When I try executing this, I get the following error:
VM288:49 Uncaught TypeError: Cannot read property 'children' of undefined
at hasRole (<anonymous>:49:71)

Any ideas as to how to fix it?

Meteor doesn't wait for the result from a function, returns undefined

I'm building a small web scraper and I have stumbled into the following problem: my applications needs to scrape different parts of a website and put the information into the database. Sometimes it gives crazy results such as duplicated entries, or it returns undefined from a function getPhoto(). However, if I only call that function (and don't run the rest of the script), it returns a correct result!
I have a for loop, that loops through different URL. It goes to each URL and scrapes the following information: 1. title, 2.description, 3. internal link, 4. calls a function that generates an image according to the title (getPhoto(...) ), 5. saves the results to the DB. Everything happens on the server (I'm using Cron jobs, no client interaction)
for (i = 0; i < AllLinks.length; i++) {
if (AllLinks[i] != undefined && AllLinks[i] != null && sepLink[2] == "www.fly4free.pl") {
var t2 = {
travelTitle: null,
travelTitle2: null,
travelTitle3: null,
travelDescription: null,
travelDescription2: null,
travelDescription3: null,
travelBuy: null,
travelBuy2: null,
travelImage: null
};
var TravelLink1 = AllLinks[i];
result = HTTP.get(AllLinks[i], {});
$ = cheerio.load(result.content);
t2.travelTitle = $('.article__title').text();
t2.travelDescription = $('.article__content').find('p').first().text();
if ($("img[src$='//www.fly4free.pl/wp-content/uploads/2016/09/lotJm.png']").parent().attr('href') != null) {
t2.travelBuy = $("img[src$='//www.fly4free.pl/wp-content/uploads/2016/09/lotJm.png']").parent().attr('href'); // Link to buy
}
if (t2.travelBuy) {
if (t2.travelBuy.split('https://').pop().split('http://').pop() != null) {
t2.travelBuy2 = t2.travelBuy.split('https://').pop().split('http://').pop(); // link ready for DB
} else {
t2.travelBuy2 = t2.travelBuy;
}
}
t2.travelTitle3 = convertCurrencyInText(t2.travelTitle, 'PLN');
t2.travelDescription3 = convertCurrencyInText(t2.travelDescription, 'PLN');
translate(t2.travelTitle3, {from: 'pl', to: 'en'}).then(res => {
t2.travelTitle2 = res.text; // title for DB
if (t2.travelTitle2) { t2.travelImage = getPhoto(t2.travelTitle2); }
translate(t2.travelDescription3, {from: 'pl', to: 'en'}).then(response => {
t2.travelDescription2 = response.text; // description for DB
if (t2.travelDescription2 != null && t2.travelTitle2 != null && t2.travelBuy2 != null && TravelLink1 != null && t2.travelImage != null) {
Links.insert({ title: t2.travelTitle2, description:t2.travelDescription2, image: t2.travelImage, buyLink:t2.travelBuy2, link: TravelLink1, datetime: new Date() });
}
}).catch(err => {
console.error(err);
});
}).catch(err => {
console.error(err);
});
}
}
"AllLinks" contains different URLs. I have problems scraping this URL: http://www.fly4free.pl/na-wakacje-do-toskanii-tanie-loty-do-pizy-z-gdanska-za-170-pln/
getPhoto() function
function getPhoto(title) {
var travelPlace = nlp(title).match('to *').out('text').replace('to','').trim();
if (travelPlace) {var travelPlace2 = travelPlace.split(' '); }
if (travelPlace2) {var travelPlace3 = travelPlace2[0] + "+" + travelPlace2[1]; }
if (travelPlace3) {
var URL = "https://pixabay.com/api/?key="+API_KEY+"&q="+travelPlace3+"&category=travel&orientation=horizontal";
var images = (HTTP.get(URL, {}));
if (images.data.totalHits > 0) {
var imageLink = images.data.hits[0].webformatURL;
return imageLink;
} else if (images.data.totalHits == 0) {
var URL = "https://pixabay.com/api/?key="+API_KEY+"&q="+travelPlace2[0]+"&category=travel&orientation=horizontal";
var images = (HTTP.get(URL, {}));
if (images.data.totalHits > 0) {
var imageLink = images.data.hits[0].webformatURL;
return imageLink;
}
}
} else if (nlp(title).places().data().length > 0) {
var result = nlp(title).places().data()[0].text.replace(/[^a-zA-Z ]/g, "").trim();
var URL = "https://pixabay.com/api/?key="+API_KEY+"&q="+result+"&category=travel&orientation=horizontal";
var images = (HTTP.get(URL, {}));
if (images.data.totalHits > 0) {
var imageLink = images.data.hits[0].webformatURL;
return imageLink;
}
} else {
var title2 = title.replace(/[^a-zA-Z ]/g, "").split(" ");
if (title2) {
for(i = 0; i < title2.length; i++) {
if (cities[title2[i]] == 1) {
var URL = "https://pixabay.com/api/?key="+API_KEY+"&q="+title2[i]+"&category=travel&orientation=horizontal";
var images = (HTTP.get(URL, {}));
if (images.data.totalHits > 0) {
var imageLink = images.data.hits[0].webformatURL;
return imageLink;
}
} else {
var URL = "https://pixabay.com/api/?key="+API_KEY+"&q=travel&category=travel&orientation=horizontal";
var images = (HTTP.get(URL, {}));
if (images.data.totalHits > 0) {
var imageLink = images.data.hits[0].webformatURL;
return imageLink;
}
}
}
}
}
}
I try to console log the results - sometimes I get a correct image from getPhoto(), but an undefined link from t2.travelBuy, sometimes vice versa. Can you tell me what I'm doing wrong? I saw some people are using Promises or async/await functions on that kind of problems. Do you think that would help me? How should I change my code in order to scrape the website without getting "undefined"?
"translate" comes from "google-translate-api" package

you can try var new_func = Meteor.wrapAsync(YOUR FUNCTION THAT HAVE CALLBACK) and the when you use new_func() it will return the result as you would expect from normal function instead of waiting for callback

Specific line having issues:

UPDATE:
New issue. Uncaught SyntaxError: Illegal return statement engine.js:282
Lines 281-282 for debugging purposes:
if (!rules)
return console.error("Expose: cant find corresponding rule")
UPDATE 2:
This is my final issue. And this whole thing will be resolved.
It looks like its another return error. But i do not understand how to properly return this part.
Heres the error but its basically the same.
Uncaught SyntaxError: Illegal return statement engine.js:295
Located at line 295
Line 293 to Line 295 for debugging purposes:

here's a fix for the block of code that's causing the error
if (window.top == window.self) {
if (document.readyState !== 'loading') {
// don't return
console.error("Expose: this script should run at document-start")
} else {
// else block for state == 'loading'
The rest of the code is unchanged except for a closing } at the end
