The current HelloWorld example on websharper.com doesn't work anymore due to changes made in WebSharper 3.4. It now requires some attributes and other stuff to compile correctly.
I am just getting started with WebSharper and I would like to see a minimum (html+javascript client-side hello world) example that works. Any help would be appreciated!
The samples on the website use Html.Client (the HTML language soon to be retired in favor of UI.Next), so to run them you need to start from a template that isn't based on UI.Next.
Following the instructions here, I was able to run them without any issues, extra attributes, etc.

I'm using react-native-vision-camera to build a QR-Code-Scanner for my app. I followed this guide by dynamsoft: https://www.dynamsoft.com/codepool/react-native-qr-code-scanner-vision-camera.html
In the beginning everything worked fine but now I'm always getting an Exception when reading QR-Codes with my camera. Even with the provided example project in the post it's not working properly anymore.
The detected result I get always has asterisks in it like this: [Attention(exceptionCode:-20111)] *ttp*//**ca*h*st*9*02/*entalobje*ts*book**98420*d*6b**-4***-9e***6*d796*0c*55
I already tried reinstalling the library and everything but I can't get it to work.
vision-camera-dynamsoft-barcode-reader has an internal dependency on DynamsoftBarcodeReader SDK and it needs an active license, which I found out in their other examples. In all their examples, public license are used which has an expiration date.
Due to this reason, I made a switch to vision-camera-code-scanner. This was already suggested in Community Plugin List of VisionCamera.
Hope this helps!
I'm working on automated test using Appium with Robot framework on Android device. I create schedule run on Jenkins. My test flow is entering some data in page A and submit, then switch to page B to check the result and switch to page A to enter a new data. I repeat this loop for around 10+ time. Everything works fine in around 4-5 rounds but after that there show up an error :
StaleElementReferenceException: Message: Cached element 'By.xpath:
//android.widget.TextView[#text='Limit']' do not exists in DOM anymore
The TextView is in the page A. I monitored the robot and saw that the TextView was shown up but the robot did not see it. I tried restart the device but the problem is not solved. I search through the internet and found some who facing the same issue but they use different programming language like Java or Python. I have no idea what I have to do next.
Development Tools :
Appium version: 1.21.0
Robot Framework version: 4.1.2 (Python 3.10.0 on win32)
First I do not use Robot Framework, but the code should be similar according to this https://robocorp.com/docs/languages-and-frameworks/robot-framework/try-except-finally-exception-catching-and-handling.
Second, I'm not sure if this is the best way to get around this. I think there is something you can do with the expected conditions class to get around this in a "cleaner way" but I'm not quite familiar with it enough to show/tell you. Instead what I've done is something like this...
from selenium.common.exceptions import StaleElementReferenceException
while some_limiting_factor:
try:
# logic for submitting page A, assertions for page B
except StaleElementReferenceException:
element = driver.find_element('By.xpath: //android.widget.TextView[#text='Limit']' )
As much as I want to cache elements in appium, it seems that the service itself does NOT want you to, at least not in my experience. Getting a fresh element(s) every time seems to ensure a "slow but steady" test. Hopefully someone can show me the deep appium secrets one day.
I have a hard time figuring out how to test in Aqueduct 3.0 Pre-Release.
I see an example in the Snippets section of the documentation that uses following to connect to an endpoint:
app.client.request("/endpoint").get()
But when I look at the example_test.dart it looks following:
harness.agent.get("/places")
So it seems that there were some changes.
In the "Writing Tests" section of the documentation I can't figure out, into which files or classes the code snippets go.
Also it took me quite a long time to figure out how to run tests:
dart test/example_dart.test
I was searching for "aqueduct test" or something similar.
Is there some more documentation, or a full code example, how to setup a test environment and write tests in 3.0 Pre-Release (with get, put, post, delete)?
The published documentation site is lagging behind, but the documentation has been written. The markdown is available here: https://github.com/stablekernel/aqueduct/blob/docs/3.0/source/docs/testing/tests.md.
It is also worthwhile to install look at the tests in the template projects, especially the larger templates: ‘aqueduct create -t db_and_auth projectname’.
I have a strange situation with a project for iOS.
Its created using browserify and React for Cordova and aimed at iOS.
We have built the project for iOS using Cordova commands without any issues. It runs with no xcode errors or Javascript errors either however none of the JS ui appears on screen. We just get a blank white screen with the system bar at the top. See attached screen shot.
So far we have found out that if you add HTML to the index.html in WWW folder it prints that fine so I assume its the JS.
When we run in a browser it works as well as building for Android.
We have no problems with anything other than iOS (simulator and device build).
hopefully someone can help me out here because I'm stumped. Please let me know what files you need to look at and I'll make them available.
Thanks in advance.

If you are using internationalization component that's because you need to use the Intl polyfill:
Intl.js and FT Polyfill Service
Intl.js polyfill was recently added to the Polyfill service, which is developed and maintained by a community of contributors led by a team at the Financial Times. It is available thru cdn.polyfill.io domain, which routes traffic through Fastly, which makes it available with global high availability and superb performance no matter where your users are.
To use the Intl polyfill thru the Polyfill service just add one script tag in your page before you load or parse your own JavaScript:
<script src="https://cdn.polyfill.io/v1/polyfill.min.jsfeatures=Intl.~locale.en"></script>
When specifying the features to use thru the polyfill service, you have to specify what locale, or locales to load along with the Intl polyfill for the page to function, in the example above we are specifying Intl.~locale.en, which means only en, but you could do something like this:
<script src="https://cdn.polyfill.io/v1/polyfill.min.js?features=Intl.~locale.fr,Intl.~locale.pt"></script>
note: the example above will load the polyfill with two locale data set, fr and pt.
This is by far the best option to use the Intl polyfill since it will only load the polyfill code and the corresponding locale data when it is really needed (e.g.: safari will get the code and patch the runtime while chrome will get an empty script tag).
source & other ways to include Intl polyfill: https://github.com/andyearnshaw/Intl.js#getting-started
You can debug the UIWebView in the simulator with Safari http://moduscreate.com/enable-remote-web-inspector-in-ios-6/. You'll probably see a big error message in the console, if not you will have access to the debugger so you can step through and sort it out.
I have had this issue in the past, it turned out to be unsupported javascript features. for example, setting default parameters in the function. I.e:
function test( myvalue=0 ) { /* ... */ };
I had to initialise the value inside the function instead. You could also try removing any ecma script 2016 features you may have implemented.
Trouble shooting this type of issue was painful. I created a minimal version of the smallest part of my product compiled and ran it on ios emulator, added another chunk of the product, rinse and repeat.
Im sure there's a better way to detect these issues, but I do not know it.
I want to insert some script into every page, which have some functions that will be called by the modified HTML of that page, using a Firefox extension. I am able to insert the JavaScript into the head of the HTML, and also modify the page, but the java script functions are not called by the onmouseover event.
Does someone has any pointer on how to do that, using java script in local extension or as a online resource.
No GreaseMonkey, I need to do it with my plugin and not ask user to install greasemonkey, my plugin and the scripts.
Greasemonkey does this. It's excellent!
Make a Greasemonkey script. See Userscripts.org for lots of example ones to work off.
Why not use Greasemonkey? It allows you to execute javascript on any page on Firefox, and if executing the code you enter isn't good enough you could dynamically add links to the head, too.
you can modify the DOM using Firebug. I am not sure if you can load files locally.. sounds malicious. Also, you can just run arbitrary javascript commands in the Firebug console (a la python/ruby console)
There are some Greasemonkey-to-extension "compilers" (or extension-wrappers) out there:
Arantius's GM compiler
Gina Trapani's multiple-GM-script compiler
I've used the first one with extensive internal tweaking over time. However, I don't believe the compiler is actively maintained (default max-version is only 3.0), so may not be up-to-date with the latest GreaseMonkey, or FireFox.
I think Gina Trapani's is more designed for multiple scripts targetting the same domain, but I haven't used it.
Neither of these is a "GreaseMonkey solution" per se, as the end-user never has to install GreaseMonkey. They get a real-live FireFox extension. The core is very similar to GM, but you can change or add as much as you like.
