Automated Selenium Testing with Jest and LambdaTest

5.3.2020
You know what the best thing is about building and running automated browser tests is? It means that the site you're doing it on really matters. It means you're trying to take care of that site by making sure it doesn't break, and it's worth the time to put guards in place against that breakages....

JavaScript Libraries Are Almost Never Updated Once Installed

5.3.2020
Some commentary from Zack Bloom on the Cloudflare Blog, looking at requests to CDNJS for versions of jQuery. What we don’t see is a decline in our old versions which come close to the volume of growth of new versions when they’re released. In fact the release of 3.4.1, as popular as it quickly...

What React Does (and Doesn’t Do)

5.3.2020
With a name as big as React, it's bound to cause some Stream-Crossing Confusion, as I like to call it. How do you center a <div> in React? Dave Ceddia: React cares exactly zero about styling. Think of it as generating the barebones HTML. React will put elements on the page, but everything...

Animate SVG Path Changes in CSS

20.2.2020
Every once in a while I'm motivated to attempt to draw some shapes with <path>, the all-powerful drawing syntax of SVG. I only understand a fragment of what it all can do, but I know enough to be dangerous. All the straight-line syntax commands (like L) are pretty straightforward and I find...

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...

The Unseen Performance Costs of Modern CSS-in-JS Libraries

13.2.2020
This article is full of a bunch of data from Aggelos Arvanitakis. But lemme just focus on his final bit of advice: Investigate whether a zero-runtime CSS-in-JS library can work for your project. Sometimes we tend to prefer writing CSS in JS for the DX (developer experience) it offers, without...

From Star Trek to Wikipedia: Crashing Bitcoin SV Fails to Impress

11.2.2020
The Bitcoin SV network and the infamous Craig Wright have been publicly scrutinized by two well known individuals. Wikipedia’s Jimmy Wales criticized BSV technology and said he doesn’t think recorded data from Wikipedia would be beneficial stored on a blockchain like BSV. Moreover...

Design Systems Blogathon

11.2.2020
It was fun watching a bunch of back and forth blogging between a bunch of smart people quoting a bunch of smart people last week. If you missed it, you might wanna start at the end and work backward. I only have one tidbit to add. I don't do much with design systems as someone who works on pretty...

Getting Fancy with position: sticky;

7.2.2020
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. What...

CSS4

4.2.2020
Tab Atkins in 2012: There has never been a CSS4. There will never be a CSS4. CSS4 is not a thing that exists. Rachel Andrew in 2016: While referring to all new CSS as CSS3 worked for a short time, it doesn’t reflect the reality of where CSS is today. If you read something...

PHP is A-OK for Templating

4.2.2020
PHP templating often gets a bad rap for facilitating subpar code — but that doesn't have to be the case. Let’s look at how PHP projects can enforce a basic Model, View, Controller (MVC) structure without depending on a purpose-built templating engine. But first, a very brief PHP history lesson The...

Smaller HTML Payloads with Service Workers

31.1.2020
Short story: Philip Walton has a clever idea for using service workers to cache the top and bottom of HTML files, reducing a lot of network weight. Longer thoughts: When you're building a really simple website, you can get away with literally writing raw HTML. It doesn't take long to need a...

How Do You Do max-font-size in CSS?

30.1.2020
CSS doesn't have max-font-size, so if we need something that does something along those lines, we have to get tricky. Why would you need it at all? Well, font-size itself can be set in dynamic ways. For example, font-size: 10vw;. That's using "viewport units" to size the type, which will...

Resizing Values in Steps in CSS

30.1.2020
There actually is a steps() function in CSS, but it's only used for animation. You can't, for example, tell an element it's allowed to grow in height but only in steps of 10px. Maybe someday? I dunno. There would have to be some pretty clear use cases that something like background-repeat: space...
