Why and how I built my own GitHub

I'm using Git and GitHub in particular a lot. And when I say a lot I really mean all the time. Recently I tracked a week of work and found that 62% of my working time goes into code reviews. Sometimes I'm checking out a branch locally and trying stuff but really most of my time goes into github.com.

Common JavaScript "gotchas"

JavaScript has been getting a lot of new, sugary features ever since we got over Harmony, while more features can allow us to write readable, high-quality code it's also easy to go overboard with what's new and shiny and run into some of the potential pitfalls.

Node.js TypeScript #11. Harnessing the power of many processes using a cluster

After finding out that Node.js is in its nature single-threaded, we might think that all the cores of your processor are meant to go to waste, but this is not necessarily the case. In the previous part of this series, we prove that Node.js creates additional threads under the hood by itself.

Angular

Rendering A List Of Mixed Components Using NgFor And NgSwitch In Angular 7.2.13

Ben Nadel demonstrates how to render a collection of mixed data types using the NgFor, NgSwitch, and NgSwitchCase directives in Angular 7.2.13. While this may at first seem daunting, separating the concerns of "layout" from the concerns of "content" causes the solution to present itself naturally.

Quick Reference For NgModel Values And Template-Driven Forms In Angular 7.2.13

NOTE: This post is primarily a note-to-self for future reference. As I've demonstrated recently, template-driven forms in Angular 7.2.13 can be very dynamic. In fact, you can even listen to the reactive events using a template-driven forms model. However, in the vast majority of use-cases, I just need a good-old Text Input with a simple [(ngModel)] binding.

@Directive().inputs And @Input() Are Not Functionally Equivalent In Angular 7.2.13

Ben Nadel demonstrates that the @Directive().inputs and @Input() meta-data syntax in Angular 7.2.13 are not functionally equivalent. This reaffirms his belief that the collocating of meta-data at the top of a class is both easier to read and, now, clearly easier to consume across a wider variety of contexts (such as class inheritance).

Sub-Classing NgForOf In Order To Make It A "Pure" Directive In Angular 7.2.13

Ben Nadel demonstrates how to sub-class the native NgForOf directive in Angular 7.2.13, creating a "pure" version of the directive - NgPureForOf - that only applies change-detection when its input bindings have been changed. This adds a micro-optimization on top of the already efficient NgForOf directive.

Understanding Mixins in Vue JS

Mixins in Vue JS are basically a chunk of defined logic, stored in a particular prescribed way by Vue, which can be re-used over and over to add functionality to your Vue instances and components. So Vue mixins can be shared between multiple Vue components without the need to repeat code blocks.
