POSSE: Reclaiming social media in a fragmented world

This rhymes nicely with Mandy’s recent piece on POSSE:

Despite its challenges, POSSE is extremely empowering for those of us who wish to cultivate our own corners of the web outside of the walled gardens of the major tech platforms, without necessarily eschewing them entirely. I can maintain a presence on the platforms I enjoy and the connections I value with the people there, while still retaining primary control over the things that I write and freedom from those platforms’ limitations.

The mathematics behind the halting problem is interesting enough, but what’s really fascinating is the community that coalesced. A republic of numbers.

New Web Development. Or, why Copilots and chatbots are particularly bad for modern web dev – Baldur Bjarnason

The paradigm shift that web development is entering hinges on the fact that while React was a key enabler of the Single-Page-App and Component era of the web, in practice it normally tends to result in extremely poor products. Built-in browser APIs are now much more capable than they were when React was first invented.

Web components have been around for quite a while, but it feels like they’re having a bit of a moment right now.

It turns out that the best selling point for web components was “wait and see.” For everyone who didn’t see the benefit of web components over being locked into a specific framework, time is proving to be a great teacher.

It’s not just that web components are portable. They’re also web standards, which means they’ll be around as long as web browsers. No framework can make that claim. As Jake Lazaroff puts it, web components will outlive your JavaScript framework.

At this point React is legacy technology, like Angular. Lots of people are still using it, but nobody can quite remember why. The decision-makers in organisations who chose to build everything with React have long since left. People starting new projects who still decide to build on React are doing it largely out of habit.

Others are making more sensible judgements and, having been bitten by lock-in in the past, are now giving web components a go.

If you’re one of those people making the move from React to web components, there’ll certainly be a bit of a learning curve, but that would be true of any technology change.

I have a suggestion for you if you find yourself in this position. Try not to bring React’s mindset with you.

I’m talking about the way React components are composed. There’s often lots of props doing heavy lifting. The actual component element itself might be empty.

If you want to apply that model to web components, you can. Lots of people do. It’s not unusual to see web components in the wild that look like this:

<my-component></my-component>

The custom element is just a shell. All the actual power is elsewhere. It’s in the JavaScript that does all kinds of clever things with the shadow DOM, templates, and slots.

There is another way. Ask, as Robin does, “what would HTML do?”

Think about composibility with existing materials. Do you really need to invent an entirely new component from scratch? Or can you use HTML up until it reaches its limit and then enhance the markup?

Robin writes:

I don’t think we should see web components like the ones you might find in a huge monolithic React app: your Button or Table or Input components. Instead, I’ve started to come around and see Web Components as filling in the blanks of what we can do with hypertext: they’re really just small, reusable chunks of code that extends the language of HTML.

Dave talks about how web components can be HTML with superpowers. I think that’s a good attitude to have. Instead of all-singing, all-dancing web components, it feels a lot more elegant to use web components to augment your existing markup with just enough extra behaviour.

Where does the shadow DOM come into all of this? It doesn’t. And that’s okay. I’m not saying it should be avoided completely, but it should be a last resort. See how far you can get with the composibility of regular HTML first.

Eric described his recent epiphany with web components. He created a super-slider custom element that wraps around an existing label and input type="range":

You just take some normal HTML markup, wrap it with a custom element, and then write some JS to add capabilities which you can then style with regular CSS!  Everything’s of the Light Side of the Web.  No need to pierce the Vale of Shadows or whatever.

When you wrap some existing markup in a custom element and then apply some new behaviour with JavaScript, technically you’re not doing anything you couldn’t have done before with some DOM traversal and event handling. But it’s less fragile to do it with a web component. It’s portable. It obeys the single responsibility principle. It only does one thing but it does it well.

Jim created an icon-list custom element that wraps around a regular ul populated with li elements. But he feels almost bashful about even calling it a web component:

Maybe I shouldn’t be using the term “web component” for what I’ve done here. I’m not using shadow DOM. I’m not using the templates or slots. I’m really only using custom elements to attach functionality to a specific kind of component.

I think what Eric and Jim are doing is exemplary. See also Zach’s web components.

At the end of his post, Eric says he’d like a nice catchy term for these kinds of web components. In Dave’s catalogue of web components, they’re called “element extensions.” I like that. It’s pretty catchy.

Or we could call them “HTML web components.” If your custom element is empty, it’s not an HTML web component. But if you’re using a custom element to extend existing markup, that’s an HTML web component.

React encouraged a mindset of replacement: “forgot what browsers can do; do everything in a React component instead, even if you’re reinventing the wheel.”

HTML web components encourage a mindset of augmentation instead.

Let’s reinvent the wheel ⚒ Nerd

Vasilis gives the gist of his excellent talk at the border:none event that just wrapped up in Nuremberg. The rant at the end chimed very much with my feelings on this topic:

I showed a little interaction experiment that one of my students made, with incredible attention to detail. Absolutely brilliant in so many ways. You would expect that all design agencies would be fighting to get someone like that into their design team. But to my amazement she now works as a react native developer.

I have more of these very talented, very creative designers who know how to code, who really understand how the web works, who can actually design things for the web, with the web as a medium, who understand the invisible details, who know about the UX of HTML, who know what’s possible with modern HTML and CSS. Yet when they start working they have to choose: you either join our design team and are forced to use a tool that doesn’t get it, or you join the development team and are forced to use a ridiculous framework and make crap.

The map-reduce is not the territory

Unlike many people, I’m not particularly worried about AI replacing peoples’ jobs, although employers will certainly try and use it to reduce their headcount. I’m more worried about it transforming jobs into roles without agency or space to be human. Imagine a world where performance reviews are conducted by software; where deviance from the norm is flagged electronically, and where hiring and firing can be performed without input from a human. Imagine models that can predict when unionization is about to occur in a workplace. All of this exists today, but in relatively experimental form. Capital needs predictability and scale; for most jobs, the incentives are not in favor of human diversity and intuition.

I just described prototype code as code to be thrown away. On that topic…

I’ve been observing how people are programming with large language models and I’ve seen a few trends.

The first thing that just about everyone agrees on is that the code produced by a generative tool is not fit for public consumption. At least not straight away. It definitely needs to be checked and tested. If you enjoy debugging and doing code reviews, this might be right up your street.

The other option is to not use these tools for production code at all. Instead use them for throwaway code. That could be prototyping. But it could also be the code for those annoying admin tasks that you don’t do very often.

Take content migration. Say you need to grab a data dump, do some operations on the data to transform it in some way, and then pipe the results into a new content management system.

That’s almost certainly something you’d want to automate with bespoke code. Once the content migration is done, the code can be thrown away.

Read Matt’s account of coding up his Braggoscope. The code needed to spider a thousand web pages, extract data from those pages, find similarities, and output the newly-structured data in a different format.

I’ve noticed that these are just the kind of tasks that large language models are pretty good at. In effect you’re training the tool on your own very specific data and getting it to do your drudge work for you.

To me, it feels right that the usefulness happens on your own machine. You don’t put the machine-generated code in front of other humans.

Conditional CSS - Ahmad Shadeed

I like to think of CSS as a conditional design language.

Yes! This is exactly what I’m talking about with declarative design!

Read on for some fantastic examples. And also, Ahmad makes a comparison between CSS and Figma, pointing out that the conditional, declarative possibilities currently aren’t available in graphic design tools.

Our web design tools are holding us back ⚒ Nerd

A good ol’ rant by Vasilis on our design tools for the web.

I wrote recently about making the switch to logical properties over on The Session.

Initially I tried ripping the band-aid off and swapping out all the directional properties for logical properties. After all, support for logical properties is green across the board.

But then I got some reports of people seeing formating issues. These people were using Safari on devices that could no longer update their operating system. Because versions of Safari are tied to versions of the operating system, there was nothing they could do other than switch to using a different browser.

I’ve said it before and I’ll say it again, but as long as this situation continues, Safari is not an evergreen browser. (I also understand that problem lies with the OS architecture—it must be incredibly frustrating for the folks working on WebKit and/or Safari.)

So I needed to add fallbacks for older browsers that don’t support logical properties. Or, to put it another way, I needed to add logical properties as a progressive enhancement.

“No problem!” I thought. “The way that CSS works, I can just put the logical version right after the directional version.”

element {
  margin-left: 1em;
  margin-inline-start: 1em;
}

But that’s not true in this case. I’m not over-riding a value, I’m setting two different properties.

In a left-to-right language like English it’s true that margin-inline-start will over-ride margin-left. But in a right-to-left language, I’ve just set margin-left and margin-inline-start (which happens to be on the right).

This is a job for @supports!

element {
  margin-left: 1em;
}
@supports (margin-inline-start: 1em) {
  element {
    margin-left: unset;
    margin-inline-start: 1em;
  }
}

I’m doing two things inside the @supports block. I’m applying the logical property I’ve just tested for. I’m also undoing the previously declared directional property.

A value of unset is perfect for this:

The unset CSS keyword resets a property to its inherited value if the property naturally inherits from its parent, and to its initial value if not. In other words, it behaves like the inherit keyword in the first case, when the property is an inherited property, and like the initial keyword in the second case, when the property is a non-inherited property.

Now I’ve got three CSS features working very nicely together:

1. @supports (also known as feature queries),
2. logical properties, and
3. the unset keyword.

For anyone using an up-to-date browser, none of this will make any difference. But for anyone who can’t update their Safari browser because they can’t update their operating system, because they don’t want to throw out their perfectly functional Apple device, they’ll continue to get the older directional properties:

I discovered that my Mom’s iPad was a 1st generation iPad Air. Apple stopped supporting that device in iOS 12, which means it was stuck with whatever version of Safari last shipped with iOS 12.
