This is my first post on stackoverflow, I've looked around and haven't found an answer to this one yet:
I've got highcharts in a gwt application running on gae. Over http highcharts works fine, forcing https through setting security-constraint as CONFIDENTIAL in web.xml causes the application to be unable to render charts.
In main html page I am calling is 'script type="text/javascript" src="js/highstock.js">
Must the application allow unsecure resources in order to run highcharts then?
In case when you would like to use highstock by SSL, you need to download file from our website and load locally.

I wonder if it is possible to use chromium engine inside google chrome or the google chrome itself to render a web page inside my WPF application instead of using traditional WebView (because it's the IE engine and it's awful -_-) or implementing CEFSharp (because it uses about 200 MB of space only for the chromium engine)
so in this case I need the target pc to has installed google chrome or any other(firefox or ...)
Soooo ... is there any solution?
thanks in advance
EDIT
I want to create applications based on web UI, - because of being easy and powerful - I know some providing this feature, e.g. CEF Sharp WPF or electron js but they include a full chromium engine with the app. I don't want this.
I want to create my app as light as possible, and my idea is to use chromium engine of a modern browser, that almost everyone has one.
For example, imagine that the user has installed google chrome.
first I locate the installation folder
I use chromium.exe -render path/to/file.html(imaginary) command to render my application UI.
finally bind the UI events to my native code. (e.g. c#(wpf) or any language that you can create desktop apps with it)
One solution is creating web apps by installing a website with the browser. but with that you cannot for example create or read some files in user pc, or any similar operation.
I'm looking for the most light-weight solution...
There is a new Chromium based WebView2 control that you can use to embed modern web content in your WPF application.
Please refer to the docs for more information about the prerequisites and how to use it:
Getting started with WebView2 in WPF
Explanation
So, let's say that you want your UI to be rendered in a chromium environment(aka a browser)… right?
let's take a look at electron js:
it uses NodeJS as backend.
it uses an embedded browser for frontend.
the language used is JavaScript due to NodeJS.
So, you want to use the client's browser to render your frontend instead of embedding a browser inside it.
well, don't embed it!!
you can create a web application(e.g. opened by typing localhost:<port> in browser1) using NodeJS and handle your IPC(between frontend and backend) using ajax calls or a socket connection.
that way you are doing exactly what an electron app does, except that, electron uses a bundled browser.
now you made your app lighter, also if your client do have NodeJS installed, you don't need to bundle NodeJS!
--- inspired by jupyter notebooks ---
Possible Solutions
use NodeJS as backend.
use python and combine it with Flask or Django as backend. (I think this would be the most lightweight solution)
use PHP as backend. (the best, personal opinion)
use ASP.NET/Blazor as backend. (as mentioned in the comments; but doesn't seem to be a lightweight solution)
or use any language that you can create a web application with that!
make a runApp.bat or runApp.sh to simply run your server and open the browser automatically.
I've a simple web server for e2e purposes, built with create react app and react app rewired.
Cypress runs perfectly against this web server, the only issue I am facing is about the fonts.
They are included with an external url.
Since I launch the web server regularly, the react application is able to be fed with the url for the proper fonts.
Once Cypress open the browser with the command cypress open the console log shows this error and fonts indeed are not loaded.
GET https://[URL.EXTENSION]/[FONT.WOFF2] net::ERR_EMPTY_RESPONSE
BEGIN EDIT
I noticed that the issue occurs on my company VPN and not on my regular network configuration, so as I already said, the fonts are not loaded just in the browser of Cypress, if I
view the website from a regular browser
access those fonts url copying them in the browser
any issue is occurring
END EDIT
Where is lying the error? Do I miss something in the configuration?
Thanks
Ok, somehow I am serving ads in my NodeJS / AngularJS application, but I haven't include this myself.
There's some package or included link sending ads to the client, but the ads are not visible, and the adserve url changes with every request. (The url that can be seen in the screenshot below)
How do I find out which place in my application serves these ads?
PS: I am sure this doesn't come from my local dev pc, my other collegues have this issue as well.
A quick trick may be to search for the url in every files of your repository. If you use a cdn to load your librairies, try to look inside also (you can do that directly in chrome dev tool with ctrl/cmd f in the sources tab).
Hope it will help !
The "adserver" in my project turns out to be a tracking / analytics beacon included by the Realtime.co framework.
Thankfully, the author responded to my email very quickly, and they also provide a beacon-free version of their framework. So problem solved :)
Just started developing hybrid apps with the ionic framework, and ran into a little problem.
I am trying to embed a Google map, but can't wrap my head around a lille issue.
First, I downloaded and implemented the "Angular Google Maps" from
http://angular-ui.github.io/angular-google-maps/
Then I created a API key through the Google developer console.
Added my applications id, from the config.xml, to the allowed url's
Added the key as part of the config section:
uiGmapGoogleMapApiProvider.configure({
key: 'added the key here',
v: '3.20', //defaults to latest 3.X anyhow
libraries: 'weather,geometry,visualization'
});
Added uiGmapgoogle-maps as a module
Placed <ui-gmap-google-map center='map.center' zoom='map.zoom'></ui-gmap-google-map> where I wanted the map to be.
....and now the problem:
When I fire up the app in the Ripple emulator, the maps shows just fine, for a second, and then tells me that the page was unable to display a Google Maps element, and gives me an "InvalidKeyOrUnauthorizedURLMapError", but it is an periodic error, because somethimes it actually works, without throwing an error, but then I try it on a live device, and the screen is just blank.
It is pretty safe to say, that I forgot something, or doing something wrong, but thank you very much in advance.
[EDIT]Well, if I remove all the restrictions for the Google Maps API, it works in the Ripple emulator, so I can change the question to: What url am I supposed to specify as allowed, when it is a cordova app?
And what causes the empty map when executed on a real device?[/EDIT]
Background:
I've built a Angular Application that works fine on browsers.
On the frontend side I have HTML/CSS/Angular/Bootstrap, backend side is Web API. So it is completely separated.
I took my front code zipped it, used Phonegap to build android app. When I run it I can see the first screen of my web site. I've confirmed that the angular code there works, cause I can see it filtered navigation based on the fact the user is not logged in.
But when I try to go to any other page of my app I get an empty screen, so I tried to remotely debug it using PG remote debugger. Every time I try to load anything but my homepage I loose connection to my target. I haven't seen any JS errors in console.
This is the only thing in the logs:
"exception firing pause event from native"
"exception firing resume event from native"
Is there some part of configuration that I missed that could cause this behavior, or is there another way I can debug this?
Since you are using angularJS, I'm guessing you are using a webserver locally to make the app run on your browser, so everything seem to work fine
Although PhoneGap uses a file server to run your app on WebView, which is similar to just opening the index.html on browser without webserver. Bottom line is if you can make your app work on desktop browser by just opening your index.html without webserver then it will work when u build as PhoneGap app.
You might run into Cross-Origin issues when testing your app on browser, this will happen if your app is making REST API calls or if you are loading angularJS templates from another .html file, these Cross-Origin restrictions are taken care in PhoneGap build. So when testing on local browser you might want to open Chrome with web security disabled.
If you have developed your app using a webserver to test, then you might have absolute URLs for loading assets or hrefs, you will have to change these to relative URL paths.
For example, change <a href="/#/next-page"> to <a href="#/next-page">, or <img src="/images/logo.png"> to <img src="images/logo.png">
