“Off The Main Thread”

10.9.2019
JavaScript is what they call "single-threaded." As Brian Barbour puts it: This means it has one call stack and one memory heap. We all feel a symptom of that regularly in the form of performance jank and non-interactivity on elements or entire sites. If we give JavaScript lots of jobs and it gets...

How to Not Minify Source with webpack

10.9.2019
The webpack JavaScript utility has taken over the modern JavaScript landscape, so much so that it’s hard to be a JavaScript developer and not use it. JavaScript build utilities are the point where they do best practices implicitly, like minify code, caching, and more. I was recently debugging...

Stop Installing Packages Globally

9.9.2019
These days, most front-end projects are going to involve NPM packages of some kind. Occasionally, when browsing documentation for these packages, I’ll see a recommendation to install a package like this. yarn global add <package> Or like this. npm install --global <package> In both...

Model-Based Testing in React with State Machines

4.9.2019
Testing applications is crucially important to ensuring that the code is error-free and the logic requirements are met. However, writing tests manually is tedious and prone to human bias and error. Furthermore, maintenance can be a nightmare, especially when features are added or business logic...

Should a website work without JavaScript?

2.9.2019
The JS Party podcast just had a fun episode where they debated this classic question by splitting into two groups of two. Each group was assigned a "side" of this debate, and then let loose to debate it. I don't think anybody can listen to a show like this and not be totally flooded with thoughts!...

Working with Attributes on DOM Elements

30.8.2019
The DOM is just a little weird about some things, and the way you deal with attributes is no exception. There are a number of ways to deal with the attributes on elements. By attributes, I mean things like the id in <div id="cool"></div>. Sometimes you need to set them. Sometimes...

Reverse Lookups with JavaScript

28.8.2019
I’ve always loved exploring regular expressions because they’re one of those skills that’s never taught in school — you need to pick them up on the fly, messing up and fixing them along the way. Regex’s are incredibly powerful, and one power they have are referred...

Promises and Static Values

23.8.2019
Async can throw a real wrench into the cogs of our programming workflows, all despite the fact that async is the modern JavaScript pattern. While async/await helps, there’s sometimes confusion about the way to have a single function that returns a value whether it exists or needs a Promise...

Navbar Nudging on @keyframers

22.8.2019
I got to be the featured guest over on The Keyframers the other day. We looked at a Dribbble shot by Björgvin Pétur Sigurjónsson and then slowly built it, taking some purposeful detours along the way to discuss various tech. We start by considering doing it entirely in CSS, then go for some light...

Let’s Build a JAMstack E-Commerce Store with Netlify Functions

20.8.2019
A lot of people are confused about what JAMstack is. The acronym stands for JavaScript, APIs, and Markup, but truly, JAMstack doesn’t have to include all three. What defines JAMstack is that it’s served without web servers. If you consider the history of computing, this type of abstraction isn’t...

Bounce Element Around Viewport in CSS

19.8.2019
Let's say you were gonna bounce an element all around a screen, sorta like an old school screensaver or Pong or something. You'd probably be tracking the X location of the element, increasing or decreasing it in a time loop and — when the element reached the maximum or minimum value —...

All the New ES2019 Tips and Tricks

13.8.2019
The ECMAScript standard has been updated yet again with the addition of new features in ES2019. Now officially available in node, Chrome, Firefox, and Safari you can also use Babel to compile these features to a different version of JavaScript if you need to support an older browser. Let’s look...

Quick Gulp Cache Busting

7.8.2019
You should for sure be setting far-out cache headers on your assets like CSS and JavaScript (and images and fonts and whatever else). That tells the browser "hang on to this file basically forever." That way, when navigating from page to page on a site — or revisiting it, or refreshing...
