Using React Loadable for Code Splitting by Components and Routes
7.3.2019
In a bid to have web applications serve needs for different types of users, it’s likely that more code is required than it would be for one type of user so the app can handle and adapt to different scenarios and use cases, which lead to new features and functionalities. When this happens, it’s...
Native Video on the Web
6.3.2019
TIL about the HLS video format:
HLS stands for HTTP Live Streaming. It’s an adaptive bitrate streaming protocol developed by Apple. One of those sentences to casually drop at any party. Äh. Back on track: HLS allows you to specify a playlist with multiple video sources in different resolutions....
CSS Algorithms
6.3.2019
I wouldn't say the term "CSS algorithm" has widespread usage yet, but I think Lara Schenck might be onto something. She defines it as:
a well-defined declaration or set of declarations that produces a specific styling output
So a CSS algorithm isn't really a component where there is some parent...
Extracting Text from Content Using HTML Slot, HTML Template and Shadow DOM
6.3.2019
Chapter names in books, quotes from a speech, keywords in an article, stats on a report — these are all types of content that could be helpful to isolate and turn into a high-level summary of what's important.
For example, have you seen the way Business Insider provides an article's key points...
The Client/Server Rendering Spectrum
6.3.2019
I've definitely been guilty of thinking about rendering on the web as a two-horse race. There is Server-Side Rendering (SSR, like this WordPress site is doing) and Client-Side Rendering (CSR, like a typical React app). Both are full of advantages and disadvantages. But, of course, the conversation...
Refactoring Tunnels
6.3.2019
We’ve been writing a lot about refactoring CSS lately, from how to take a slow and methodical approach to getting some quick wins. As a result, I’ve been reading a ton about this topic and somehow stumbled upon this post by Harry Roberts about refactoring and how to mitigate the potential risks...
The Bottleneck of the Web
5.3.2019
Steve Souders, "JavaScript Dominates Browser CPU":
Ten years ago the network was the main bottleneck. Today, the main bottleneck is JavaScript. The amount of JavaScript on pages is growing rapidly (nearly 5x in the last 7 years). In order to keep pages rendering and feeling fast, we need to focus...
Why I Write CSS in JavaScript
5.3.2019
I'm never going to tell you that writing your CSS in CSS (or some syntactic preprocessor) is a bad idea. I think you can be perfectly productive and performant without any tooling at all. But, I also think writing CSS in JavaScript is a good idea for component-based styles in codebases that build...
CSS Triangles, Multiple Ways
5.3.2019
I like Adam Laki's Quick Tip: CSS Triangles because it covers that ubiquitous fact about front-end techniques: there are always many ways to do the same thing. In this case, drawing a triangle can be done:
with border and a collapsed element
with clip-path: polygon()
with transform: rotate()...
Learning to Learn
4.3.2019
There’s been a lot of talk recently about whether or not you need a degree to be in tech (spoiler: you don’t). But please don’t take this to mean you don’t need any kind of education to be in tech, because by not getting a degree, you’re opting to replace the imposed learning structure of...
CSS Remedy
4.3.2019
There is a 15-year history of CSS resets. In fact, a "reset" isn't really the right word. Tantek Çelik's take in 2004 was called "undohtml.css" and it wasn't until a few years later when Eric Meyer called his version a reset, that the word became the default term. When Normalize came around,...
Mask Compositing: The Crash Course
2.3.2019
At the start of 2018, as I was starting to go a bit deeper into CSS gradient masking in order to create interesting visuals one would think are impossible otherwise with just a single element and a tiny bit of CSS, I learned about a property that had previously been completely unknown to...
Do CSS Custom Properties Beat Sass Loops?
2.3.2019
I reckon that a lot of our uses of Sass maps can be replaced with CSS Custom properties – but hear me out for a sec.
When designing components we often need to use the same structure of a component but change its background or text color based on a theme. For example, in an alert, we might need...
Should I Use Source Maps in Production?
1.3.2019
It's a valid question. A "source map" is a special file that connects a minified/uglified version of an asset (CSS or JavaScript) to the original authored version. Say you've got a filed called _header.scss that gets imported into global.scss which is compiled to global.css. That final CSS file...
Writing Tests for React Applications Using Jest and Enzyme
1.3.2019
While it is important to have a well-tested API, solid test coverage is a must for any React application. Tests increase confidence in the code and helps prevent shipping bugs to users.
That’s why we’re going to focus on testing in this post, specifically for React applications. By the end, you’ll...
Why CSS Needs its Own Survey
1.3.2019
2016 was only three years ago, but that’s almost a whole other era in web development terms. The JavaScript landscape was in turmoil, with up-and-comer React — as well as a little-known framework called Vue — fighting to dethrone Angular.
Like many other developers, I felt lost. I needed some...
Recreating the Facebook Messenger Gradient Effect with CSS
1.3.2019
One Sunday morning, I woke up a little earlier than I would’ve liked to, thanks to the persistent buzzing of my phone. I reached out, tapped into Facebook Messenger, and joined the conversation. Pretty soon my attention went from the actual conversations to the funky gradient effect of the message...

I Spun up a Scalable WordPress Server Environment with Trellis, and You Can, Too
28.2.2019
A few years back, my fledgling website design agency was starting to take shape; however, we had one problem: managing clients' web servers and code deployments. We were unable to build a streamlined process of provisioning servers and maintaining operating system security patches. We had...
