Web Component for a Code Block
18.2.2020
We'll get to that, but first, a long-winded introduction.
I'm still not in a confident place knowing a good time to use native web components. The templating isn't particularly robust, so that doesn't draw me in. There is no state management, and I like having standard ways of handling that. If...

Listen to your web pages
16.2.2020
A clever idea from Tom Hicks combining MutationObserver (which can "observe" changes to elements like when their attributes, text, or children change) and the Web Audio API for creating sounds. Plop this code into the console on a page where you'd like to listen to essentially any DOM change...

Why JavaScript is Eating HTML
13.2.2020
Web development is always changing. One trend in particular has become very popular lately, and it fundamentally goes against the conventional wisdom about how a web page should be made. It is exciting for some but frustrating for others, and the reasons for both are difficult to explain.

Building an Images Gallery using PixiJS and WebGL
12.2.2020
Sometimes, we have to go a little further than HTML, CSS and JavaScript to create the UI we need, and instead use other resources, like SVG, WebGL, canvas and others.

How to Fetch and Parse RSS Feeds in JavaScript
11.2.2020
Say you have an RSS feed like this one. The goal is to request that RSS feed, parse it, and do something useful with the data in it. RSS is XML, and XML is arguably not as easy to work with than JSON. While a lot of APIs offer JSON responses, it's less typical for RSS, although it does exist.

Override window.alert
11.2.2020
For years the only bit of feedback web developers could get was via alert("{str}") calls. These days we have the web console but, in rare cases, we don’t have a console and alert calls are our only window into a value at a given time. One problem: if an alert sneaks into production code, your...

Mike Solomon worked on a fancy scrollytelling post for Esquire and blogged about it. It has GIFs of each step along the way of figuring out not just position: sticky; but also using negative margins, wrapper divs, backgrounds, and even a smidge of JavaScript measuring to get it all right.

Please raise your hand if you’ve ever faced never-ending content revision requests from your clients. It’s not that the changes themselves are difficult, but wouldn't it be less complicated if clients could just make the revisions themselves? That would save everyone valuable time, and  allow...
Freezing User-Agent Strings
3.2.2020
There's been news about Chrome freezing their User-Agent string (and all other major browsers are on board). That means they'll still have a User-Agent (UA) string (that comes across in headers and is available in JavaScript as navigator.userAgent. By freezing it, it will be less useful over time...
