I tried to use socket.io in an simple app.
When it is calling the following js file:
node_modules\socket.io\lib\transports\websocket.js
The following line failed to load (It didn't really fail. It actually returned some empty result and failed some later codes using protocolVersions):
var protocolVersions = require('./websocket');
I debugged a little bit and it seems that the intention of this line is to load the following js file:
node_modules\socket.io\lib\transports\websocket\index.js
However because there is also a "websocket.js" (the file being run) under the "transports" folder, the require functions always tries to load "websocket.js" instead, and return some unexpected results.
I changed the folder name to "websockets" and call "require('./websockets')" instead, and it fixed the problem. However this is a shared library I am not feeling comfortable messing up its codes.
I am trying to understand why this problem happened this way and what should be the best way to work around it. I am sure this piece of codes has been well tested before released.
You probably already noticed that I am using backslash '\' to separate the path. Yes I am running it on Windows! Will that create any difference?
Thanks!

Recently I started having Issues with the Google Tag Manager.
I can't track it to a Tag or a Trigger (activated and deactivated individually to check).
The error started occurring this week (no updates were made to the system or template). I noticed when testing the implementation of a new Tag in GTM. That shortly worked but then this error message started showing in the console. Removing the new Tag didn't change the situation and since the code worked for a while (some 30minutes) I don't expect a direct relationship between the new tag and the error.
All I have is the console in the frontend that shows the following error message:
Uncaught TypeError: Wb.set is not a function
The error stems from this file:
https://www.googletagmanager.com/gtm.js?id=GTM-XXXXXXX
Wb is started as a Map just a few steps earlier:
Wb=new Map(Vb.h.F);
Wb.set("style",{ya:4});
The GTM Script is copied and pasted from the GTM-Admin without any change made to it and is included in the header.php file of the Wordpress template. I tried copying it again and replacing the script that was in the header.php previously but the result was the same.
If looking at the actual error message in the console helps, the issue can be seen on the following URL:
https://www.bindella.ch
Any help in solving this or at least pointer to where to go look for errors would be very much appreciated.
Thanks
Very interesting, and yes, you're right, the error in the minified code makes no sense:
Let's try something different. First, just export your GTM container (the workspace that is synced with prod/live) as a JSON file in Admin section.
Open the file, look for something like set("style" See if you can find that Wb. Well, don't expect it to be Wb. I guess GTM minifies the code. It may be some weird chat bot, or something like that. From there, you'll be able to find the tag or variable that causes the issue.
I didn't look too deep into it, but that part of code looks sophisticated enough to be a part of the core container code. Actually, we can check it right here, on SO cuz it uses GTM too, let's do that.
Yes, SO has identical code. Looks like it's indeed core GTM. Well, there's a tiny probability that when you built the prod library last time, GTM had an issue and it deployed an artefact.
Try making a new workspace, make a nonsensical change in it and publish it to production. See if it lets you publish. Then see if that fixes the issue.
Now, if it doesn't then the next thing I'd try is trying to re-importing the exported JSON, forcing GTM compare the import to what's there and find differences.
Now if that shows no issues, then I would make a brand new container, load the config in it and try replacing the gtm loading script to see if the error still happens. It sounds like you can do that. If you can't, look a plugin like redirector to redirect the request to a different container.
Still the error with the new container? How about if you load a completely empty container? Got any errors?
There's a very slim chance that your front-end deploys one of a few vars GTM uses too, thus conflicting with your GTM. But it's very unlikely. Why would you use something like google_tag_manager or google_tag_data in the global scope...
If nothing helps and only the empty container doesn't give errors, then... well, then make a list of all tags firing along that error and start disabling them one by one. Or use breakpoints to narrow it down to the tag/library that causes it.
I am working on a project built with Javascrpt, jQuery, and Vite.js. My colleague built a data visualization using D3 - a US states map - that I need to implement in the project on a specific page. They built the component using test data, my job is basically to load the component onto a page passing it actual returned data from an API call.
Everything in the test project works perfectly, but when I tried to implement this code into a script file in the project - literally copying and pasting from the working version - I got an error saying certain properties could not be read. After failing to debug for sometime, I randomly tried removing type="module" from the script tag link in HTML, and boom, everything worked. Does anyone have an idea of why this would be? I cannot get this code to run when the script type is set to module, except I need the script type to be set to module since I'm importing lots of components for other aspects of the page.
With the way the CodePen is set up, I couldn't replicate the issue since the HTML and JS files are automatically linked. But if you copy this code into your editor, and then in the html, set the the JS file to a module ` You'll see the issue.
Thanks. I'm at a total loss for what to do here. I could put all the D3 code in it's own script file, but then I have no way pass it variables from other files if it's not a module.
Per the comments, the following lines in my original code were not working in strict mode:
this.uStates = uStates;
this.uStatePaths = uStatePaths;
The fix was simple, I just needed to write the following instead:
window.uStates = uStates;
window.uStatePaths = uStatePaths;
firstly very sorry, I cant find out what the real problem is.
I ll try to explain.
My client given code which is developed using opencart and nitropack.
he includes common.js in header, it is basic js file with some ajax calls, UI events etc which has 1297 lines(no formating in code, lots of blank spaces, blank lines etc).
my real problem is, when I made any changes in this file,
the browser console is throwing error invalid or unexpected token.
I checked the common.js file in browser console, seeing that some kind of reddots added at last of the file. I just added a alert() at the begining of file. nothing else.
very sorry, dont know how to explain more detaily.
This is the first time I have seen this kind of issue.
when I removed the alert(), the error gone.
In my python code using web.py, I am trying to call js library in main layout.
Here is the code snippet -
$var js: static/js/jquery-3.4.0.min.js static/js/bootstrap.min.js static/js/material.min.js
However, when I execute the code it gives me this error:
127.0.0.1:51225 - - [04/May/2019 07:05:29] "HTTP/1.1 GET /âModels/js1/bootstrap.min.js"" - 404 Not Found
I have also added screenshot of the code and folder structure as attachment. What I can see is that during the call to library, it adds the special characters â and then instead of single quotes there are double quotes at the end. I suspect this is the problem for the library not found.
I was thinking that this could be because of UTF-8 issues. Hence i went and also updated the encoding standards to UTF-8 both at server and client level. But even this is not solving the problem. Can someone please help with suggestions here. I have been struggling this from last 4-5 days and trying to research everything that could help but not of much use.
I'm using PyCharm for development.
The js library path is correct and it should have been called. If it calls then my js code will be executed. Please suggest if I'm doing something wrong here.
PROBLEM DESCRIPTION.
I'm trying to follow https://github.com/lucascosta/facebook-js-ads-sdk to install the Javascript SDK for Facebook. Before anyone objects, I am absolutely aware of the compact version (https://developers.facebook.com/docs/javascript/quickstart), but that API is absolutely useless to me. I need the one produced by Lucas Costa, in order to be able to make changes to my ads account, which the recommended script by Facebook does not enable.
As usual installation instructions (see github.com/lucascosta/facebook-js-ads-sdk) are horribly predicated on mysterious conditions, that are unbeknown to me. I cannot get the SDK to work and would like someone to tell me explicitly what to do. The crux of the problem is the paradoxical situation: I am supposed to use a require('...') command (where??) to include the SDK (where is this supposed to be saved??) and yet require cannot be used on folders, but on scripts. Maybe somewhere there is a require.config file, I'm supposed to set up, but I have no idea, as, like I said, the instructions completely bypass any mention of the necessary starting conditions.
Here is what I have done so far. My folder-structure looks like this (I don't even know if this is right, as no-one explains it anywhere!):
[Serverroot]
— [folder with my website]
– facebook-ads-sdk (the folder one gets by downloading)
– css — pagestyles.css
– js — lib
require.js
— app
( some header scripts )
– img
( some images )
index.php
In index.php I have a block of html followed by some javascript. It is here, that I try to insert the setup / example code from . The browser cannot even get past the line const adsSdk = require('facebook-ads-sdk');. I have tried a number of things: require('./facebook-ads-sdk');, moving all this to the folder ./js/app in a script main.js and then writing in my html in index.php where main and require are located. Setting up a require.config (or requirejs.config) replacing require by requirejs, etc. and including the appropriate scripts in the <head> part of index.php. Nothing helps. Here are the errors: first with const adsSdk = require('facebook-ads-sdk'); I get
Error: Module name "facebook-ads-sdk" has not been loaded yet for context: _. Use require([])
Okay. How do I ‘load the Module for the context _’?? Reading requirejs.org/docs/start.html is of no help here. I tried require([], function() {require('facebook-ads-sdk')}); Same error. I tried require(['facebook-ads-sdk']);
I tried using the following commands in my script in index.php:
require.config({
shim: {
'facebook': {
exports: 'adsSdk',
},
},
paths: {
'sdk': './facebook-ads-sdk',
}
});
var adsSdk = require(['sdk']);
Then I get the error
Failed to load resource: http:// .... /facebook-ads-sdk.js the server responded with a status of 404 (Not Found)
Ie, the browser thinks I'm trying to include a script facebook-ads-sdk.js, but I’m supposed to(???) ‘require’ the entire folder! What is going on? Can someone please give me thorough instructions about the necessary folder structure and command, in order to get this SDK working?
Why is this so infuriatingly vaguely described online? Is there some kind of mysterious way of installing SDKs, about which ‘everyone’ knows, but never mentions?
UPDATE: SOLUTION. For any future google-searches for this same problem: via the following simple methods, one can install & embed the Javascript-FB-Ads-SDK:
install via npm install --save facebook-ads-sdk a copy of the npm modul Lucas Costa’s facebook-ads SDK.
Copy this folder to your website’s architecture (actually you possibly just need one subfolder / file).
in your HTML include the script (via <script type='text/javascript' src='...'></script>) with the src pointing to the file in the facebook-ads-sdk folder: /dist/iife.js.
In your page’s script, you now have access to then API via the global variable fb.
alternatively to 3:
3’. in your HTML headers make sure to include the require.js script via a <script>-tag. Then in your website’s javascript apply the following commands anywhere:
require.config({
paths: {
'sdk': './[FOLDERNAME OF SDK]/dist/iife',
}
});
require(['sdk']);
Credit and special thanks goes to #SLaks and #KhauriMcClain (I would give you up-points if I could) for this solution.
The instructions are assuming that you're using a bundling system like Webpack or Browserify.
If you are, the instructions "just work"; you can require() it and everything will work fine.
If you're building a non-trivial codebase, you really should use such a system.
If you aren't, you can reference iife.js in a <script> tag and that will create global variables.
You need to change the way you are using require.
You cannot use the synchronous require method to load dependencies if they have not been loaded before. Hence const adsSdk = require('facebook-ads-sdk'); will not work. You will need to use the form require(['name-of-script'], callback).
Require does not allow you to load an entire folder. You have to find the exact script you are trying to work with so var adsSdk = require(['sdk']); will not work.
Ultimately your code should look something like:
require(['some-facebook-script'], function(someFacebookScript) {
// Do some work here
});
The parameter passed to the callback function will be the loaded module you are trying to consume. When using the asynchronous version (as I just demonstrated) the return from require is not useful.
