This post documents my fabulous journey through time to uncover the hidden traps of trusting the claim that once you have package.json and package-lock.json and same NodeJS version you are safe.
If you use winget upgrade over your packages, you migt see that some packages fail to update and will stay on the same version. In this article I try to fix this.
In this article I compared isNaN(Date.parse(string)) with isNaN(new Date(string).valueOf()) and isNaN(new Date(string)). There are some funny differences in the results depending on your browser and his JS engine.
Maybe you just use good old http and overlooked it. Try https and things will be fine again :) The hackers will not thank you too.
This small how to is targeted at people who want to run the Bryntum PDF export server with IIS server if they host it's JS part in for example ASP.NET application.
Yes it can, he is quite good at it but you maybe will not get what you want with legacy code. Also you might consider using ChatGPT 4 to generate test, it seems Copilot might generate different results.
Don't ask for ES6, ask for latest EcmaScript version/feature set. Making code use latest ES features will help readability but might hurt performance.
If you try to use nvm under Windows and load default version of node like (expected) : you will see : Reason seems to be that : .nvmrc is…
I was thinking about doing this kind of article for quite some time now, mostly since I discovered Android app named AccuBattery (you can easily download it on play store, no referral links needed here). There are more apps that will tell you the temperature and voltage and current but I will use this one as sample in my article.

The problem OK so you need to debug remotely again. You have the same os or at least the closest you can get, same .NET version, same tools…
We have all been there. Eval is evil "BUT" here is this HTML element prop and you need to call this like it is. OK, sure, it worked until now. But it was a good old sync JS function. Now there might be an async function and we need to await it. Now what?
This is a small helper I created for myself and colleagues to create names of test for maven from Jenkins list of failed tests.

PowerShell Invoke-WebRequest has a nice feature, a progress bar which will as you will see turn off immediately. Here is why.

In this post we will discuss some options you have with calling async functions in constructor of your TypeScript classes.
If you have in your project files you moved to different location or removed but your .csproj still points to lets say - removedFolder/removedSubfolder/removedFile.ts then it might happen VS will recreate folders where you point (in this case removedFolder/removedSubfolder).

When checking for primitive types in TypeScript , typeof variable === “string” or typeof variable === “number” should do the job. When checking for HTMLElement or HTMLDivElement type of objects, variable instanceof HTMLElement or variable instanceof HTMLDivElement type of check should be the right one.
Just add HintPath node to Microsoft.Web.Infrastructure Reference node that points to where NuGet package is.
Basically you can now limit types that could be used in Array (all only at compile time, same rules apply as for other type checking features of TypeScript)
You can just drag and drop .ts file to .html or .aspx markup and Visual Studio 2013 is intelligent enough to include .js file

Since I play these days a lot with PowerShell I need from time to time some simple functionality. Sometimes dead simple.
So you want to search for multiple strings in your files on Windows?
So, you wanted to use momentjs to parse from locale date and time and/or month and day names , or you wanted some locale output from date using .format in your browser, but what you received was a mess?

PowerShell installs in one package however there are two versions x86 and x64 (as separate executables that I had to find on my drive) and as you might guessed correctly - they don’t share the same Get-ExecutionPolicy setting!
Funny article name you say and I can only agree, yes 🙂 most of the time you run like hell when you see page with broken certificate. But I will explain why one might need this 🙂
I would like to share one small “feature” I have found on current latest browsers. By “latest browsers” I mean (I tested this behavior on IE 11, FireFox 29 and Chrome 37).
Since I write a lot of JavaScript currently in Visual Studio these days, I lack one of the very common checks in JavaScript and that is testing if object exists.

Since I upgraded my Windows 7 developer box with Internet Explorer 11 I am very satisfied with how Microsoft upgraded developer tools. They have added new stuff and it works (well from time to time IE freezes but that might be also my problem with my JavaScript since other browsers hang/crash from time to time on my code also). But that is another story..
For some reason, account on which you run VS on and on which VS hosts PowerShell has restricted ExecutionPolicy (you can type Get-ExecutionPolicy , select the text and hit CTRL+F8 and should see Restricted as the answer)....

We have entity that has reference to another entity. Employee has reference to Status. This second Status table has set for some business requirement that his Summary property must be set to value that can repeat.
