Pivoting From React to Native DOM APIs: A Real World Example - The New Stack

One dev team made the shift from React’s “overwhelming VDOM” to modern DOM APIs. They immediately saw speed and interaction improvements.

Yay! But:

…finding developers who know vanilla JavaScript and not just the frameworks was an “unexpected difficulty.”

Boo!

Also, if you have a similar story to tell about going cold turkey on React, you should share it with Richard:

If you or your company has also transitioned away from React and into a more web-native, HTML-first approach, please tag me on Mastodon or Threads. We’d love to share further case studies of these modern, dare I say post-React, approaches.

Every website and web app should have a service worker | Go Make Things

Needless to say, I agree with this sentiment.

I’ve worked with a lot of browser technology over the years. Service workers are pretty mind-blowing.

The bar to overriding browser defaults should be way higher than it is.

Amen!

Standing still - a performance tinker | Trys Mudford

What Trys describes here mirrors my experience too—it really is worth occasionally taking a little time to catch the low-hanging fruit of your site’s web performance (and accessibility):

I’ve shaved nearly half a megabyte off the page size and improved the accessibility along the way. Not bad for an evening of tinkering.

The environmental benefits of privacy-focussed web design - Root Web Design Studio

Even the smallest of business websites now seems to have cookie popups simultaneously telling us they ‘value your privacy’ while harvesting data about who we are, where we are, what we’re looking for and what we were doing online before we landed there.

Tracking scripts have become so pervasive that they have effectively become an industry standard, and most businesses deploy them not only without question, but without consideration of what it means for customer privacy.

Care

I know that the number one cause of jank and breakage is another developer having messed with the browser’s default way of doing things.

THIS!!! A thousand times, THIS!

What Is A Single-page Application?: HeydonWorks

You can’t create a complex modern web application like Google Mail without JavaScript and a SPA architecture. Google Mail is a webmail client and webmail clients existed some time before JavaScript became the language it is today or frameworks like Angular JS or Angular BS existed. However, you cannot create a complex modern web application like Google Mail without JavaScript. Google Mail itself offers a basic HTML version that works perfectly well without JavaScript of any form—let alone a 300KB bundle. But, still, you cannot create a complex modern web application like Google Mail without JavaScript. Just keep saying that. Keep repeating that line in perpetuity. Keep adding more and more JavaScript and calling it good.

JavaScript Bloat in 2024 @ tonsky.me

This really is a disgusting exlusionary state of affairs.

I hate to be judgy, but I honestly wonder how the people behind some of these decisions can call themselves web developers.

SpeedCurve | The psychology of site speed and human happiness

Tammy takes a deep dive into our brains to examine the psychology of web performance. It opens with this:

If you don’t consider time a crucial usability factor, you’re missing a fundamental aspect of the user experience.

I wish that more UX designers understood that!

Cameron Dutro on ruby.social

Here’s the inside scoop on why Github is making a bizarre move from working web components to a legacy React stack.

Most of what I heard in favor of React was a) it’s got a good DX, b) it’s easy to hire for, and c) we only want to use it for a couple of features, not the entire website.

It’s all depressingly familiar, but it’s very weird to come across this kind of outdated thinking in 2023.

My personal prediction is that, eventually, the company (and many other companies) will realize how bad React is for most things, and abandon it. I guess we’ll see.

Introduction to web sustainability | MDN Blog

You might think that any individual effort to reduce the web’s environmental impact is a drop in the ocean. But as tech workers, we are in a position of relative power compared to other industries. We build products that might be used by thousands, even millions of users. Any improvements we make have the potential for a vast impact when scaled up to that level.

A good overview from Michelle.

CSS { In Real Life } | Greenwashing and the COP28 Website

Maybe when I wrote about performative performance? Michelle has a prime example:

The low carbon toggle does absolutely nothing.

In fact, worse than nothing. It doesn’t prevent images being downloaded. It doesn’t switch the site to dark mode, or prevent autoplaying animations (e.g. the hero carousel), or reduce resources transferred in other way. All it does is overlay an extra element with a background gradient on top of the large images on the site to give the appearance that those images being prevented from loading.

The Cost Of JavaScript - 2023 - YouTube

A great talk from Addy on just how damaging client-side JavaScript can be to the user experience …and what you can do about it.

Jack Franklin – Abstractions, complexities and off-ramps – All Day Hey! 2023 - YouTube

This is a terrific talk by Jack on how to deal with the tooling involved in modern front-end development:

• Maintaining control,
• Dependency awareness,
• Lean on browser primitives,
• Have an exit strategy.

Google AMP: how Google tried to fix the web by taking it over - The Verge

AMP succeeded spectacularly. Then it failed. And to anyone looking for a reason not to trust the biggest company on the internet, AMP’s story contains all the evidence you’ll ever need.

This is a really good oral history of how AMP soured Google’s reputation.

Full disclosure: I’m briefly cited:

“When it suited them, it was open-source,” says Jeremy Keith, a web developer and a former member of AMP’s advisory council. “But whenever there were any questions about direction and control… it was Google’s.”

As an aside, this article contains a perfect description of the company cultures of Facebook, Apple, and Google:

“You meet with a Facebook person and you see in their eyes they’re psychotic,” says one media executive who’s dealt with all the major platforms. “The Apple person kind of listens but then does what it wants to do. The Google person honestly thinks what they’re doing is the best thing.”

Spot. On.

How slimmed-down websites can cut their carbon emissions - BBC News

Interesting to see an article on web performance on the BBC. Perhaps we should be emphasising green over speed?

Behind the scenes, animation and interaction effects were added using HTML and CSS, two fundamental web languages. That meant there was no need to download large JavaScript files often used to do this on other sites.

On Container Queries, Responsive Images, and JPEG-XL – Cloud Four

Container queries can’t be used in the sizes attribute for responsive images. Here, Jason breaks down why that is (spoiler: it’s the lookahead pre-parser) and segues into a truly long term solution: a “magical” image format.

If you’ve ever thought it felt weird to put media conditions inside the HTML for responsive images, this will resonate.
