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...
Custom Styling Form Inputs With Modern CSS Features
7.2.2020
It’s entirely possible to build custom checkboxes, radio buttons, and toggle switches these days, while staying semantic and accessible. We don’t even need a single line of JavaScript or extra HTML elements! It’s actually gotten easier lately than it has been in the past. Let’s take a look.
Here’s...
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.

Here’s a great in-depth post from Adam Silver about his journey to create an autocomplete field that’s as accessible as possible. There are so many edge cases to consider! There are old browsers and their peculiar quirks, there are accessibility best practices for screen readers, and not to mention...
Creating an Editable Webpage With Google Spreadsheets and Tabletop.js
5.2.2020
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...

Have you ever needed a countdown timer on a project? For something like that, it might be natural to reach for a plugin, but it’s actually a lot more straightforward to make one than you might think and only requires the trifecta of HTML, CSS and JavaScript. Let’s make one together!
This is what...

Understanding Immutability in JavaScript
30.1.2020
If you haven’t worked with immutability in JavaScript before, you might find it easy to confuse it with assigning a variable to a new value, or reassignment. While it’s possible to reassign variables and values declared using let or var, you'll begin to run into issues when you try that with...
Practice GraphQL Queries With the State of JavaScript API
29.1.2020
Learning how to build GraphQL APIs can be quite challenging. But you can learn how to use GraphQL APIs in 10 minutes! And it so happens I've got the perfect API for that: the brand new, fresh-of-the-VS-Code State of JavaScript GraphQL API.
The State of JavaScript survey is an annual survey of...
Apollo GraphQL without JavaScript
29.1.2020
It's cool to see progressive enhancement being done even while using the fanciest of the fancy front-end technologies.
This is a button in a JSX React component that has a click handler applied directly to it that fires a data mutation Ajax request through Apollo GraphQL. That is about the least...
Bundling JavaScript for Performance: Best Practices
24.1.2020
Performance advice from David Calhoun on how many scripts to load on a page for best performance:
[...] some of your vendor dependencies probably change slower than others. react and react-dom probably change the slowest, and their versions are always paired together, so they...
Searching the Jamstack
22.1.2020
Here's Raymon Camden on adding site search functionality to a site that is statically hosted. A classic trick! Just shoot 'em to Google and scope the results to your site:
<form action="https://www.google.com/search" method="get"<input type="search" name="q"...
JAMstack vs. Jamstack
21.1.2020
It's just a word to evoke the idea that serving as much as you can statically while using client-side code and hitting serverless APIs for any needs after that.
The "official website" changed their language from JAMstack (evoking the JavaScript, APIs, and Markup acronym) to Jamstack. It's nothing...
Getting Started with Front End Testing

Amy Kapernick covers four types of testing that front-end devs could and should be doing:
Linting (There's ESLint for JavaScript and Stylelint or Prettier for CSS.)
Accessibility Testing (Amy recommends pa11y, and we've covered Axe.)
Visual Regression Testing (Amy recommends Backstop, and we've...
Eleventy Love
17.1.2020
Been seeing a lot of Eleventy action lately. It's a smaller player in the world of static site generators, but I think it's got huge potential because of how simple it is, yet does about anything you'd need it to do. It's Just JavaScript™.
Jason Lengstorf and Zach Leatherman did a Learn...
Autumn (macOS window manager)
17.1.2020
I love how nerdy this is. Autumn allows you to write JavaScript to control your windows. Get this window, move it over here. Nudge this window over. There are all sorts of APIs, like keyboard command helpers and doing things on events, like waking up from sleep.
I love that it exists, but for...
