194028 – Add limits to the amount of JavaScript that can be loaded by a website

Now this is a feature request I can get behind!

A user must provide permission to enable geolocation, or notifications, or camera access, so why not also require permission for megabytes of JavaScript that will block the main thread?

Without limits, there is no incentive for a JavaScript developer to keep their codebase small and dependencies minimal. It’s easy to add another framework, and that framework adds another framework, and the next thing you know you’re loading tens of megabytes of data just to display a couple hundred kilobytes of content.

I’m serious about this. It’s is an excellent proposal for WebKit, similar to the never-slow mode proposed by Alex for Chromium.

An Abridged History of Safari Showstoppers - Webventures

In an earlier era, startups could build on the web and, if one browser didn’t provide the features they needed, they could just recommend that their users try a better one. But that’s not possible on iOS.

I’m extremly concerned about the newest bug in iOS 18:

On-screen keyboard does not show up for installed web apps (PWAs) when focusing a text input of any kind

Whaa? That’s just shockingly dreadful!

With great power, comes great creativity: thoughts from CSS Day 2024 · Paul Robert Lloyd

Here’s Paul’s take on this year’s CSS Day. He’s not an easy man to please, but the event managed to impress even him.

As CSS Day celebrates its milestone anniversary, I was reminded how lucky we are to have events that bring together two constituent parties of the web: implementors and authors (with Sara Soueidan’s talk about the relationship between CSS and accessibility reminding us of the users we ultimately build for). My only complaint is that there are not more events like this; single track, tight subject focus (and amazing catering).

Intent to Ship: View Transitions Same-Origin Navigation

Finally! View transitions for multi-page apps (AKA websites) will be landing in Chrome soon—here’s hoping other browsers follow suit. Mozilla are up for it. Apple are, as usual, silent on their intentions.

Nice to see a blog post of mine referenced to show that this is a highly-requested feature. Blogging gets results, folks!
