Windows Store App (JavaScript) stopped displaying embedded web fonts - javascript

We use javascript/Angular inside our application and have a few different typefaces saved into a fonts folder within the project.
During a recent update the app stopped loading/displaying multiple fonts for no reason and with no alerts/errors.
The splash screen is taking considerably longer now as well so I assume it's related.
I reverted the code to before the edit and the issue persist.
I thought it may be visual studio so I upgraded to 2015, still has the problem.
I've done a ton of reading and I cant seem to figure out what would cause the webfonts not to load, hoping someone has some insights because I'm at a bit of a dead end.

ASP.Net Core caching

I have a .js file that is being statically served in my application. This file will continue to change through the course of development-
I had made some changes to the file this morning as I normally do. Debugging the project, I discovered that the changes in the .js were not reflected- i.e. the browser was using an older version of the javascript file.
I have been working on this project for a few weeks and the changes in the .js file have always been reflected in the next debug until today. I have tried in both Chrome and Edge.
What gives? I'm puzzled about the change in behavior. I did receive a Windows update overnight, could it be there's a global setting for browser caching which was previously disabled on my system and was enabled by the update. I am aware of cache busting techniques but in the past, I've always just been able to update the a static .js file and the browser has always used the latest .js file.
Hopefully someone else might find this helpful. I was poking around Visual Studio and in the "play button" next to IIS Express, there is a menu option called "Script Debugging" that I happened upon and was set to disabled. I enabled the setting and things are back to working as previously.
I was able to confirm that by disabling the setting, Chrome and Edge use a cached version of the script file.
My guess is a Windows update disabled the setting. Can someone explain how changing this setting in Visual Studio affects caching in browsers?

XAMPP won't update web source files until they're committed to Git on Chrome

I'm trying to create a web application for university. I've been doing fine with XAMPP, using Visual Studio Code and Sublime Text as my editors and so far so good. However, a couple of days ago, I ran into what seemed to be a bug.
While accessing "localhost" on Chrome, the website didn't seem to reflect the last changes to the HTML and CSS code. I also modified some Javascript and it didn't work either, the website stayed the same.
Not even simple things like changing a colour on CSS or adding an alert window on Javascript would appear on the actual web.
Inspecting the website in Chrome shows the old documents and source code, however, when going to the "htdocs" folder at XAMPP, the documents were successfully changed, and no matter what I did, relaunching XAMPP or Chrome didn't fix it either.
I decided to give up for the day and committed the changes to my GitHub repository. To my surprise, I refreshed the website afterwards and it worked.
I thought it was an isolated bug, but it seems like it is not, it happened today again while working on a completely different project.
What's more surprising, this behaviour doesn't seem to happen on Firefox or even Safari, I've tried both and it seems to be fine. However, I prefer the tools included in Chrome, so I'd rather use this one.
Has anyone else had the same issue? If so, how did you fix it? Or in case it is intended to work like that, why is it? I don't see any possible scenario where this could be useful.
Thank you in advance.
This is more of a workaround than a solution really, but you could just try ctrl+F5, this will clear your cache and you're good to go again.
This is probably the single worst Chrome bug when you're doing incremental small changes but Chrome loads it from the cache and not the original files.
What does Ctrl+F5 do?
This ignores the page saved in the cache and does a fresh GET. This should serve well enough as any changes made will be reflected in Chrome on doing so. Or you can manually clear the cache from the Chrome settings.

Will Apple reject Cordova applications that download additional JavaScript

all.
My team has been toying with the idea of developing an iOS app using Cordova, and recently, we've been looking into offloading as much of the main JavaScript as possible to our server, in an attempt to speed up fixing critical bugs.
The idea would be to have:
the native app containing all HTML, CSS, plugins and Cordova files
the main JavaScript added to the pages as external scripts from a server
a device-ready function for each page that will set up and start the main JavaScript once it's available
I have seen comments that Apple could be trusting of code that runs in a webview, but it does seem like projects like this could be a security issue.
I am aware of other questions and the like that touch on this, but I feel that the context was always different.
Thanks!
A year ago apple changed the iOS Developer Program Agreement to allow download of code, see the Section 3.3.2
3.3.2 An Application may not download or install executable code. Interpreted code may only be used in an Application if all scripts,
code and interpreters are packaged in the Application and not
downloaded. The only exception to the foregoing is scripts and code
downloaded and run by Apple's built-in WebKit framework, provided that
such scripts and code do not change the primary purpose of the
Application by providing features or functionality that are
inconsistent with the intended and advertised purpose of the
Application as submitted to the App Store.
So, as you are using cordova, and cordova uses WebKit framework, if you don't change the main purpose of the Application, you won't be rejected
The answer is it depends on how you use the system. The technical ding that hits most people is Apple iTunes Guidelines - 2.12
Apps that are not very useful, unique, are simply web sites bundled as Apps, or do not provide any lasting entertainment value may be rejected
It seems clear to me, but as a volunteer on the "official" phonegap forum, I'm often very blunt with people on this point. Nothing worst than months of work for nothings
On the Javascript idea, loading the javascript file from the web is not good practice. If your app ever loses the network, your app will be non-responsive. One app that I can name, that was growing by leaps and bounds, that has this problem is Word with Friends. I play and I can see the stall every time.
Make sure you App is always responsive and if not, give a short reasonable explanation. LIKE,"Opps, we can't find the Internet."
I have seen comments that Apple could be trusting of code that runs in a webview, but it does seem like projects like this could be a security issue.
Yes, Apple trust code that runs in webview, because it is not a browser. However, that does not make it secure. We have plenty of security issues and bugs. A recent security issues allows rogue code to insert weblinks into webview, and thereby allow the App to be used as an attack vector. Another recent security issue will launch rogue code from and mp3 file! And this bugs goes back to Android 2.0.
The cure is worst than the problem. It's a huge whitelist protocol that is confusing because of the bad documentation. Luckily, I should have a blog post in a few days; other people are working on blog posts too. my raw notes are online or read the current issues especially #10.
I am aware of other questions and the like that touch on this, but I feel that the context was always different.
Feel free to read my notes. The one i give to people all the time is:

local ga.js prevents app from syncing on Samsung SmartTV 2013

I'm trying to test my app on a new Samsung SmartTV 2013, however when I include google's ga.js locally into my bundle the TV rejects the app and will not install it at all.
The error message provided points to this page: http://www.samsungdforum.com/support/tvappssecurity. Which is pretty vague and unhelpful in this situation.
Any one have a work around for this? I've already looked on the Samsung D Forum.
Thanks!
The TVAppsSecurity is well known error - I have seen it tens of times. It basically says that your code violates Samsung security restrictions. In practice the static source code analysis on TV detects some security flaws.
Note that it is up to you to identify the issue and fix it. Since you know the file that causes the problem - you can easily separate it into test project. Then just start deleting portions of the code until you will be able to install the application. It is annoying, but it will take 60 minutes maximum. Note that sometimes it is even enough to rename the file.
I am not sure if the ga.js hosting is really a problem (see there https://support.google.com/analytics/answer/1032389?hl=en)
You can include ga.js by loading it from external host. In this case it will not be checked during install on TV.

Trouble with iOS and PhoneGap

Just started trying to adapt my html, css, javascript files to iOS using PhoneGap (I've also tried NimbleKit but the result is the same). I have a web app that I originally wrote for the Blackberry Playbook. The app works fine on the Playbook and in Chrome and Safari. However, when I try and run it through XCode with PhoneGap, the app displays on the simulator but does not seem to properly run the database coding (at least I think that is the problem). I do not get any build errors.
From the documentation, NimbleKit seems to just support its own internal SQLite, but PhoneGap seems to support WebDB, which is what my database is written in.
Finally, the simulator doesn't seem to run some global variables I have (I know, I know, don't use global variables) although that could be because they appear just after my DB initialization at the beginning of my javascript file.
Any thoughts or points in the right direction would be very helpful. Even if it is to some documentation which can help me debug the app in the iOS sim.
Thanks in advance.
Cold your problem be related to this?
http://phonegap.com/2012/04/18/ios-5-1-and-the-embedded-uiwebview-with-cordova/
I was facing a similar problem with PhoneGap and iOS Simulator last week,
all the code i wrote seem to have no problem,
anyway i tried this remote web inspector, and tried to create a database remotely using Safari Javascript Console,
bottom line I found that I was not able to create web database using iPhone Simulator,
looks like you need to deploy your app onto your device to make use of it.
I might be wrong, but that was what I found.
