git: Remove Untracked Files

19.11.2020
I’ve always said that I know just enough about git to get the job done, but also do something destructive. Nothing embodies that more than my recent mistake. I somehow found a git repository full of untracked files and git stash wouldn’t fix it. Desperation led me to learning how...

Node isConnected

13.11.2020
Every so often I discover a property in JavaScript objects that I didn’t know existed, oftentimes using another trick to accomplish the same functionality. One such property I just learned about was isConnected, a node property that attached to a context (i.e. document). Here’s how...

Detect Changed Files with git

26.10.2020
There are numerous reasons to want to know which files have been added or modified in a git repository, one of which is your text editor highlighting those files. Another use case is running tasks against only files which are presently changed, like lint or other validation routines. So how can...

One pattern in the JavaScript API world that web development veterans will notice is that we’ve been creating new methods to accomplish what older, grosser APIs once achieved. XMLHttpRequest became the fetch API, some APIs like Battery became async, and there are dozens of other examples....

How to Prevent Pasting into an Input

19.10.2020
Every once in a while I get to a website that doesn’t allow me to paste into a form input. In most cases it’s something to do with login credentials (username and or password) and auth codes. So how are they preventing me from pasting information? It’s as easy as you’d...

How to Conditionally Add Attributes to Objects

16.10.2020
JavaScript is full of tricks that you don’t know you want until you … want … them. Or maybe just until you see them. One trick I recently realized was conditionally adding attributes to React elements. Of course this trick essentially boils down to conditionally adding properties...

39 Shirts – Leaving Mozilla

6.10.2020
In 2001 I had just graduated from a small town high school and headed off to a small town college. I found myself in the quaint computer lab where the substandard computers featured two browsers: Internet Explorer and Mozilla. It was this lab where I fell in love with Mozilla — a browser that...

Curate Custom Content with mediastack

6.10.2020
I used to have a personal aggregator of sites I enjoyed but maintaining it was a nightmare. I needed to grab each site’s RSS feed, categorize their contents, deal with errors and individual rate limits, etc. I had to tear the whole project down because it was a nightmare to manage. Fast...

How to Detect When a Sticky Element Gets Pinned

5.10.2020
The need for position: sticky was around for years before it was implemented natively, and I can boast that I implemented it with JavaScript and scroll events for ages. Eventually we got position: sticky, and it works well from a visual perspective, but I wondered how can we determine when...

Shoelace 2.0: A Forward-thinking Library of Web Components

29.9.2020
A few years ago, I released a lightweight alternative to Bootstrap affectionately named Shoelace. Shoelace was small and fast because of its minimal design and pure CSS approach to styling. It used CSS custom properties extensively to enable customizations, even when loaded via CDN — something...

How to Detect the Default Branch in a git Repository

28.9.2020
Over the past few years, many engineering teams have switched their default git branch name from master to a different, potentially less offensive term. I’m all for choosing to name your default branch whatever you’d like, but not having a universal default branch name can complicate...

How to Create an Async Function

24.9.2020
One thing I love about JavaScript is that there are many ways to accomplish the same task, one such example being creating functions. There are several patterns for functions; one of the last you see used is the new Function method: /* new Function(arg1, arg2 (...), body) */ const myFunction =...
