Recently I’ve been building out something that is very configurable. Tons of different settings, switches, numbers… you name it. Its nice to have things split out into areas of concern – that is, different interfaces identifying the configuration settings pertinent to a particular thing – but then you end up with all of these things … [Read more…]
I was trying to be good and keep up with my Karma unit tests in my Angular 5 Typescript project, but I was running in to a really weird error that left a lot to be desired: The logs in the console window are not helpful either… Chrome 63.0.3239 (Windows 10 0.0.0) ERROR Uncaught NetworkError: … [Read more…]

Recently I was trying to create a parser that would try a few different regular expressions and output an object with the proper fields defined.

The class border-left-0, border-top-0, etc, seem like they should work to specify a width… but they are for hiding specific portions of the border instead. This didn’t really make sense to me – after all, a border with a … [Read more…]
Lodash is a pretty cool utility library for doing stuff in javascript objects. The maintainers have done a lot of work to make it as efficient as possible, (about 4kB gzipped and minified), so it won’t eat up a bunch of resources on your web application. One of the reasons I always seem to bring … [Read more…]
I’ve found this guide on creating an Angular 4 inside of .NET core very helpful. One of the steps is to set up .NET core to serve static files: However, if you add routing to Angular 4, there’s an additional step that will allow your routes to resolve correctly in the angular application if a … [Read more…]
