We are developing a react/typescript/redux app and have the problem, that we want to work on a component, which is only visible under certain conditions. So the workflow is: Change code, compile it (fast), then reload the app in browser and then click through the app, until the condition for the visibility is met.
To speed this "click-through" up, we thought about initialising the app with some saved state instead of clicking through the app.
We know of course, that the redux-developer-tools enable to export/import a redux-state, and we had also other ideas, but we asked us, if there are better/faster/simpler methods to set the state.
Cause this feature is only needed during development: Some simple to use - eventually "dirty" - methods of loading a saved state after the bootstrap? What do you think about using redux-storage, especially https://www.npmjs.com/package/redux-storage-engine-jsurl?

I have a Xamarin.Forms app that opens locally saved HTML files which contain relative link to each other (think an old HTML offline docs) in a WebView. Everything functioned in Android 10, but now I needed to make a custom renderer in Xamarin.Android due to the new Android 11 changes needing AllowFileAccess (I have all accesses currently on for testing until I get this problem fixed) in the WebSettings. The WebView's OnElementChange sets all the Control's settings, sets the WebClient (which has a ShouldOverrideUrlLoading set to handle particular filetypes like PDF), and then loads the URL. The first page loads fine, but none of the links operate (this testing page has a few links to other HTML pages and some to PDFs). Click on the highlights them as normal, but nothing opens.
No breakpoints in the WebClient's ShouldOverride are hit and neither are any in the Android WebView's OnElementChanged when I click a link. The output window registers the touch, but doesn't do anything more. I feel like this is some kind of communication problem between Xamarin.Forms WebView and Xamarin.Android WebView (possibly even the Xamarin.Android's WebView not being up to date with Android's WebView), but I do not know where to look. Has anyone run into a similar situation and have a fix to get the links functioning again?
Thanks.
After much blood, sweat, and tears, mostly tears, I found the solution.
First off, WebView doesn't tell you directly, but anything that targets a new window (IE _blank and potentially others) will not hit your WebViewClient's ShouldOverrideUrlLoading method and instead hit your WebViewChromeClient's OnCreateWindow method. So you need to handle loading through that one as well as through your WebViewClient.
Second, links will not always work because of Safe Browsing in the WebView. Again, Google doesn't specifically say it can cause issues with urls, but it works against outside urls (which in a file is potentially every url). I had to turn it off, which you can find instructions at developer.android.com/guide/webapps/managing-webview, and I was able to navigate just fine. I feel you will want to set up safeguards to prevent people from abusing your app (like having a WebView that is for your stuff with Safe Browsing off and another for all others, or blocking any sites that aren't yours) since cybersecurity is always a thing.
Lastly, I found IFrames won't load properly if you manually load the page in the view passed to WebViewClient's ShouldOverrideUrlLoading. The sizing goes all off in my docs, which leads me to believe the elves in the background do something special if you return false and the WebView handles it. I found I needed to handle all my other cases (IE pdfs, images, etc) and then return false from ShouldOverrideUrlLoading if it is my iframe htmls.
As a note, because I had forgotten this having worked on Windows for so long, remember that Android's base file system is case sensitive, which makes links case sensitive. You need to either makes sure all your casing is correct in your files or have them on a FAT file system SD card if you want them to be insensitive.
Hello I am developing a website on ASP.NET and while developing it I am also testing its behavior and changes. The problem I am facing is some times when I make change on .CSS file those changes does not appear on the browser even when I refresh it or rerun the project but when I run that project on different browser it began to show those changes. If it is a code related or browser related or IDE related please let me know. Thanks
Try hitting ctrl-F5 - that will force a re-load.
Unless you change the name of the css file or other resource, the browser can cache that information for months on end.
In fact, some utilities will even add say a dummy parameter to the linked css file - thus on each build the parameter is updated - and thus the browser will not use the older cached value (but, I not found a great working and easy to use utility that does this).
The other way? Empty your browser cache. So yes, the cache can be a REALLY nasty issue during development. And in fact it can be REALLY nasty when you update your site - users will not see say a modify css file, since it been cached, and with the same name, then users will not see new fixes/style changes or even even things like text alignment that you fixed in the css file.
As noted, in most cases, if you launch a page, then try hitting Ctrl-F5 (I think this works in most browsers). If that fails, then you have to in the browser re-set the cache (empty the cache), and then you see the new changes.
I wish had a better solution, and I wish one could just say:
Ok, please re-set ONE time for all past users - since they will often not see your changes - and you don't have much control with any real great ease to re-set the cached information. There are truck-loads, book sized articles in dealing with this issue, but sadly, there not really a great solution right now. If you want say things like cached css stuff to go away client side? Then you have to change the name of the css file - and that can be painful.
At least during development? Well, let the page load, then try Ctrl-f5 - that works well in most cases.
I am implementing a feature using "connectivity" from essentials that when the app goes "offline" no wifi etc.. it navigates to a specific page.
It works in most cases however if I set the phone on "Airplane Mode" when I am on a modal page it does not navigate to my page.
In Prism is there a way to detect if the current page "IsModal" and either goback or kill it so that I can navigate to my specific Page?
THanks
You'd have to write some crazy lookup logic to figure it out. Unfortunately the helper for that doesn't currently exist. However the latest Prism 7.2 preview has some enhancements that specifically attempt to eliminate the need to figure out whether you require Modal Navigation and automatically use the proper type of Navigation. I would encourage you to try the preview. If you come up with a scenario where GoBack isn't working correctly please open an issue.
I'm trying to develop my first app, starting to create a new one...
I can't find in documentations where to change the getting start dialog https://snag.gy/JWliB7.jpg
I'm looking everywhere, configs, settings but no luck.
Any help please?
The getting started as of now is tied in with the app catalog. The reason behind it is fairly complex, but we basically wanted to make sure that the getting-started comes from outside the app itself, so that security warnings etc. could be shown at a later time.
If you need a kind of a "user getting started" and not an admin/developer getting started, for now I recommend that you create a view like "0 getting started" so it's the first to be shown, and in those instructions you can also explain how to set this view to hidden once the user understands all.
Is it OK to use threading.sleep in an intranet web application to display AJAX loading (in production environment)? Off course, the application works fine without it but all works too quick for the end user or even a developer to notice any difference.
What is the recommended approach ?
Just read this thread: I am amazed: you want an application to fetch data slower? That sounds really strange to me.
You should try to make it clear to the user that the new data is loaded. You can use an animation or something like a highlight color for new items. Maybe a 'new' icon?
Imagine that the servers are running slow deu to some errors. Than the user still has to wait an extra second to see the data. Just something to think about.
