Fire and forget template for C#/.NET to run something that you don't need to wait on and don't care about the results.

Task.Run(() =>
{
	//code goes here
});

In ReactJS, if ESLint says you cannot use inline arrow functions to pass in props in JSX, a solution is to wrap them with the useCallback hook.

Modals — can be used to add dialog or popup info boxes on your ReactJS app.

So using this library actually helped me solve my Azure Application Insights logging issue. The issue being, since I had a dateOfBirth object in my formData object, app insights would save it as an object, as opposed to something like dateOfBirth: 2024-04-16. The solution was to flatten the formData object so it will get logged properly in Azure App Insights.

To cause Azure to keep sending emails repeatedly for your Heath Check alerts, you need to uncheck the checkbox that says “Automatically Resolve Alerts”.

If you want to see what kind of error Axios throws, it is better to use console.log(error.toJSON()) than console.log(error). That's because the former option will list out all the properties from the error variable, while the latter option will only list out the error message itself.

Instead of adding todo comments, track it as a task so it doesn't get lost.

Looking for a new way to do end-to-end testing on modern web apps? Check out Playwright. The tests are pretty easy to follow because it's basically a set of instructions written in code. So as you might have guessed, it's catered more to developers than non-technical folks.

I am going through the Pro ASP.NET Core 6 book. After trying to run the command libman install bootstrap@5.1.3 -d wwwroot/lib/bootstrap from page 72 (Chapter 4) of the book, I started getting the error listed below:

[LIB002]: The "bootstrap@5.1.3" library could not be resolved by the "cdnjs" provider

Turns out it was an issue with the library manager package that was installed. The fix is to install a newer one. More info can be found here:

Was looking for a way to add a list of objects to the appsettings.json file, then retrieve that list and turn them into something I can check against in a controller class. This answer works wonderfully.

React Hook Form — seems like a cool alternative form handler for React.

SQL to MongoDB Mapping Chart — good reference on how to write MongoDB queries based on expected SQL Server queries.

Reasons to blog if you're a software developer:

  • It helps you write better emails at work.
  • It helps you write better user stories and acceptance criteria.
  • It helps you communicate your ideas better.

If you're noticing a pattern there, it's all about being a better communicator. And you would want that, because that also helps you advance in your career.

Cache Implementations in C# .NET — good blog post on implementing caching with .NET.

You're using HttpClient wrong and it is destabilizing your software — great blog post that told me that we should avoid the use of the “using statement” when working with an HttpClient instance. And that's because disposing it after say a one time use, like doing one API call and then immediately disposing, will leave open/pending socket connections. Do this often enough and you'll accumulate a number of those open/pending socket connections and that will slow down your app. The better approach is to use a single static HttpClient instance in your app.

What is a react helmet?

  • React helmet is a helper component that allows you to add data to the <head> section of a document or HTML page. It basically allows you to add <link> tags, <scripts> and other tags that goes into the <head> section of an HTML page.

So react-helmet library didn't work for me, but this one did.

The equivalent of the npm install command in yarn is yarn without any parameters.

Was trying to help out someone on discuss.write.as get a logo to show up beside their blog title. I learned that you can actually set the size of the background image using something like background-size: 150px;. Cool stuff.

Reference: Resizing background images with background-size

So last time I decided to just not show a header image for my Now Listening to... website on mobile screens. It was because I didn't know how to handle it. Well my easy solution turned out to be getting a smaller sized image to use as a header image. Then I was able to just add a css media screen entry that uses the smaller sized image.

Co-worker was running into Gatsby/Kentico/Grahpql errors with one of our projects. We pretty much had the same .env file and code base. Deleting the folder and downloading again didn't fix it. What worked for him was running the command npm cache clean --force.

Note: This is probably a dangerous command to run. Please research what it does before you try it out. I'm only sharing what worked for me and my team. But this was a last resort type of attempt to fix our errors.

To create a repository from an existing folder or files using Github Desktop, first you have to create the repository on the app itself. This is so that the app can create and initialize the folder on your drive. Then you can copy over the files into the folder that the app created. And then you're set.

To copy the _redirects file (or any other file for that matter) to the Output folder in Wyam, you can use the pipeline code below:

Pipelines.Add(
    // Copy redirect file to the output folder
    CopyFiles("_redirects")
);

Starting a new DevNotes series. This is a spin-off from my Weeknotes series. This one focuses on software development content only. This one won't exactly be a weekly thing. I'll only publish a DevNotes post when I have a number of notes to share. Otherwise I'll bundle them up into a bigger post and publish then. And with that out of the way, let's get started...

I'm starting to notice a trend with the Rust programming language. It seems to be the next big thing. Microsoft even joined the Rust Foundation. It probably should be the next language I should learn after React.

I just realized, after installing the React Browser Dev Tools Extension, that Microsoft's Azure DevOps site was built using React. If Microsoft, who created C# and ASP.NET, uses React on their core products, it is just one more reason for me to really dig into React.

React components can be thought of as building blocks for your website. Instead of creating a button then styling it with the primary-button CSS class, you create a PrimaryButton component then use it wherever you want.

Reference: Get to Know Gatsby Building Blocks

I was building a very basic Gatsby website, the one from their tutorial. It was taking too long to build the output for a static site. Too long compared to building sites using Wyam. I don't have anything against Gatsby. In fact I'm trying to learn Gatsby. I'm just pointing out that it seems slow compared to Wyam.

While going through the Gatsby tutorial, I found another alternative to Netlify for hosting static sites: Surge.
