We’re going to use a simple restaurant set-menu example to explore TypeScript types. By the end of this thought-process, we’re going to be able to require one out of two members that are present on a type. Here’s the scenario. You have a set three-course menu. It looks like this: type SetMenu = { starter: […]
One of the most common issues I see in content-managed websites is the presence of a fully-qualified image address that isn’t secure when the website itself is. When this happens, you’ll need to find all images that aren’t secure and fix them. For example, if you are visiting https://www.example.com and there is an image http://www.example.com/image.png […]
If you are terminating inactive sessions in your ASP.NET MVC application and you add an AJAX polling call, the chances are you’ll make your sessions last forever thanks to the AJAX request bringing down an updated session cookie. This is because the AJAX call will pull down an updated auth cookie and extend your timeout. […]
If you were a fan of ASP.NET MVC Widgets using Html.RenderAction, you might be a bit stunned that RenderAction is nowhere to be found in .NET Core. Don’t worry, though, because there is a Html.RenderAction equivalent in .NET Core MVC and it’s called View Components. View Component Class The view component class is quite a […]
Linq is not just the go-to .NET library for handling IEnumerable data sources, it’s the inspiration for many successful and unsucessful attempts to reproduce the style in other languages. When you have a class full of Linq and you find yourself wanting to simply map a single object to something else, you’ll find yourself writing […]
If you fire up a new TypeScript app and whack it into Node, you might come across the following error about The ESM Module Loader is Experimental. (dev) root@dev:~$ node –experimental-modules run.ts (node:11333) ExperimentalWarning: The ESM module loader is experimental. (node:11333) Warning: To load an ES module, set “type”: “module” in the package.json or use […]
I have long held fast to a basic principle of letting type inference do your work for you. That means not adding type annotations unless you have a good reason to. I thought I would supply a bit more information on where to put your TypeScript type annotations and when they add value rather than […]
There is a little setting in your ASP.NET Web.config file that sets compilation debug to true. If you debug your application locally, this gets set for you if it hasn’t been set already… <system.web> <compilation debug=”true” targetFramework=”4.5.2″ /> <!– … –> This is necessary for debugging, but also costly. That’s why your default Web.Release.config transform […]
As today’s Cloudflare outage rages on, with a multitude of services that depend on Cloudflare being knocked out of operation simultaneously, we are all reminded about resilience. In particular, it’s a good time to think again about edge workers. Cloudflare is quite amazing. It handles huge amounts of traffic using just a small number of […]
Has you ASP.NET applicaiton reported that minification failed? If you are using bundles in application, you might come across this exception comment at the top of your larger-than-expected bundle file. /* Minification failed. Returning unminified contents. (List of problems here) */ It can happen for JavaScript or CSS, but it means minifier has found something […]
