Rotten Apple

The European Union’s Digital Markets Act is being enforced and Apple aren’t happy about it.

Most of the discussion around this topic has centred on the requirement for Apple to provision alternative app stores. I don’t really care about that because I don’t really care about native apps. With one exception: I care about web browsers.

That’s the other part of the DMA that’s being enforced: Apple finally have to allow alternative browsing engines. Hallelujah!

Instead of graciously acknowledging that this is what’s best for users, Apple are throwing a tantrum.

First of all, they’re going to ringfence any compliance to users in the European Union. Expect some very interesting edge cases to emerge in a world where people don’t spent their entire lives in one country.

Secondly, Apple keep insisting that this will be very, very bad for security. You can read Apple’s announcement on being forced to comply but as you do you so, I’d like you to remember one thing: every nightmare scenario they describe for the security of users in the EU is exactly what currently happens on Macs everywhere in the world.

This includes risks from installing software from unknown developers that are not subject to the Apple Developer Program requirements, installing software that compromises system integrity with malware or other malicious code, the distribution of pirated software, exposure to illicit, objectionable, and harmful content due to lower content and moderation standards, and increased risks of scams, fraud, and abuse.

Users of macOS everywhere are currently exposed to all the risks that will supposedly overwhelm iOS users in the European Union. Weirdly, the sky hasn’t fallen.

It’s the same with web browsers. I just got a new Mac. It came with one browser pre-installed: Safari. It’s a good browser. But I also have the option of installing another browser, like Firefox (which I’ve done). A lot of people just use Safari. That’s good. That’s choice. Everyone wins.

Now Apple need to provide parity on iOS, at least for users in the EU. Again, Apple are decribing this coming scenario as an absolute security nightmare. But again, the conditions they’re describing are what already exist on macOS.

All Apple is being asked to do is offer than the same level of choice on mobile that everyone already enjoys on their computers. Rather than comply reasonably, Apple have found a way to throw their toys out of the pram.

As of the next update to iOS, users in the EU will no longer have homescreen apps. Those web apps will now launch in a browser window. Presumably they’ll also lose the ability to send push notifications: being a homescreen app was a prerequisite for that functionality.

This is a huge regression that only serves to harm and confuse users.

I have a website about traditional Irish music. Guess where a significant amount of the audience is based? That’s right: Ireland. In the European Union.

There is no native app for The Session, but you can install it on your phone nonetheless. Lots of people have done that. After a while they forget that they didn’t install it from an app store: it behaves just like any other app on their homescreen.

That’s all about to change. I’m going to get a lot of emails from confused users wondering why their app is broken, now opening in a regular browser window. And I won’t be able to do anything about it, other than to tell them to take it up with Apple.

Presumably Apple is hoping that users will direct their anger at the EU commission instead. They’re doing their best to claim that they’re being forced to make this change. That’s completely untrue. A lie:

This is emphatically not required by the EU’s Digital Markets Act (DMA). It’s a circumvention of both the spirit and the letter of the Act, and if the EU allows it, then the DMA will have failed in its aim to allow fair and effective browser and web app competition.

Throughout all their communications on this topic, Apple are sticking to their abuser logic:

Look what you made me do!

This is going to hurt me more than it hurts you.

Apple’s petulant policy of malicious compliance is extremely maddening. What they’re about to do to users in the EU is just nasty.

This is a very dark time for the web.

I feel bad for the Safari team. They’ve been working really hard recently to make Safari a very competitive browser with great standards support with a quicker release cycle than we’ve seen before. Then it all gets completely torpedoed at the level of the operating system.

I really hope that Apple won’t get away with their plan to burn down web apps on iOS in the EU. But hope isn’t enough. We need to tell the EU commission how much damage this will do.

If you’ve ever built a web app, then your users will suffer. Remember, it’s a world wide web, including the European Union.

Create a PDF with the following information:

  • Your company’s name.
  • Your name.
  • That your company operates or services the EU.
  • How many users your service has in the EU (approximately).
  • The level of impact this will have on your business.
  • The problems this will cause your business.
  • Whether or not the submission is confidential.

The submission can be as short or long as you want. Send it to contactus@open-web-advocacy.org, ideally before Monday, February 19th.

I know that’s a lot to ask of you on your weekend, but this really matters for the future of the web.

At the very least, I encourage to get involved with the great work being done by the Open Web Advocacy group. They’re also on Discord.

Please don’t let Apple bully an entire continent of users.

Progress

The opening of my talk Of Time And The Web deals with our collective negativity bias. The general consensus is that the world has become worse. Crime. Inequality. Poverty. Pollution. Most people think these things are heading in the wrong direction.

But they’re not. Every year the world gets better and better. But it’s happening gradually. Like I said:

If something changes gradually, we don’t notice it. We literally exhibit something called change blindness.

But we are hard-wired to notice sudden changes. We pay attention to moments of change.

“Where were you when JFK was assassinated?”

“Where were you on September 11th?”

Nobody is ever going to ask “where were you when smallpox was eradicated?”

I know it might seem obscene to suggest that the world is getting better given the horrific situation in Gaza and the ongoing quagmire in Ukraine. But the very fact that the world is united in outrage is testament to how far we’ve come.

I try to balance my news intake with more positive stories of progress. Reasons to Be Cheerful is one good source:

We tell stories that reveal that there are, in fact, a surprising number of reasons to feel cheerful. Many of these reasons come in the form of smart, proven, replicable solutions to the world’s most pressing problems. Through sharp reporting, our stories balance a sense of healthy optimism with journalistic rigor, and find cause for hope. We are part magazine, part therapy session, part blueprint for a better world.

Most news outlets don’t operate that way. If it bleeds, it leads.

Even if you’re not actively tracking positive news on a daily or weekly basis, the end of the year feels like a suitable time to step back and take note of our collective progress.

Future Crunch has 66 Good News Stories You Didn’t Hear About in 2023:

The American journalist Krista Tippett says that we’re all fluent enough by now in the language of catastrophe and dysfunction, and what’s needed are more of what she calls ‘generative narratives.’ This year, we found over 2,000 of those kinds of stories, and shared them with tens of thousands of readers in a weekly email. Not dog-on-a-surfboard, baby-survives-a-tornado stories, but genuine, world changing stuff about how millions of lives are improving, about human rights victories, diseases being eliminated, falling emissions, how vast swathes of our planet are being protected and how entire species have been saved.

The Progress Network reports that something good happened every week of 2023:

Despite the wars, emergencies, and crises of 2023, the year was full of substantive good news.

Positive.news has its own round-up. What went right in 2023: the top 25 good news stories of the year:

The ‘golden age of medicine’ arrived, animals came back from the brink, the renewables juggernaut gathered pace, climate reparations became reality and scientists showed how to slow ageing, plus more good news.

On the topic of climate change, the BBC has nine breakthroughs for climate and nature in 2023 you may have missed:

Record-setting spending on clean energy in the US. A clean energy milestone in the world’s power sector. A surge in lawsuits against polluters. A treaty for the oceans 40 years in the making.

This year has seen some remarkable steps forward in tackling the nature and climate crises.

That’s the kind of reporting we need more of. As Kate Marvel wrote in the New York Times, “I’m a Climate Scientist. I’m Not Screaming Into the Void Anymore.”:

In the last decade, the cost of wind energy has declined by 70 percent and solar has declined 90 percent. Renewables now make up 80 percent of new electricity generation capacity. Our country’s greenhouse gas emissions are falling, even as our G.D.P. and population grow.

There’s a pernicious myth that a crisis mindset is necessary to drive change. I think that might be true for short-term emergencies, but it’s counter-productive for long-term problems.

Speaking for myself, I am far more likely to take action if I can see that progress has already been made, and that my actions won’t be pointless. Constant doomerism isn’t just lazy, it’s demotivational. See my excoriating words when reviewing Paolo Bacigalupi’s The Water Knife:

Instead of asking what the future might actually be like, it instead asks “what’s the absolute worst that could happen?” Frankly, it’s a cop-out.

As we head in 2024 it’s worth taking stock of the big-picture improvements we’ve collectively made so that we can continue the work.

If the news headlines continue to get you down, take some time to browse around Our World In Data.

And if you find yourself instinctively rejecting all these reports of progress, ask yourself why that might be. As I said in my talk:

We have this phrase: “sounds too good to be true.”

But we don’t have this phrase: “sounds too bad to be true.”

Stuck in the dock

I was impressed with how Safari now allows you to add websites to the dock:

It feels great to have websites that act just like other apps. I like that some of the icons in my dock are native, some are web apps, and I mostly don’t notice the difference.

Trys liked it too:

For all intents and purposes, this is a desktop application created without a single line of Swift or Objective-C, or any heavy Electron wrappers.

Oh, and the application can work offline! Service workers, and browser storage are more than stable enough to handle a variety of offline loading patterns. These are truly exciting times to be building for the web!

There was one aspect that I was particularly pleased with. External links:

Links within a Safari-installed web app respect your default browser choice.

Excellent! Except it’s no longer true. At least not in some cases. The behaviour is inconsisent but I’m running the latest version of Safari on the latest version of Sonoma, and now external links in a Safari-installed web app are broken. They just stay in the same application.

I thought maybe it was related to whether the website’s manifest file has the display value set to “standalone” rather than, say, “minimal ui”. Maybe the “standalone” instruction is being taken literally? But even when I change the value I’m still getting the broken behaviour.

This may sound like a small thing, but it completely changes the feel of using the web app. Instead of feeling like “I’m using an app that just happens to be on the web”, it now feels like “I’m using a web browser but with fewer features.”

I’ve been loving having Mastodon as a standalone app in my dock. It used to be that if I clicked on a link in a Mastodon post, it would open in my browser of choice (Firefox) where I could then bookmark it, or do any other tasks that my browser offers me. Now if I click on a link in Mastodon, I’m stuck in the same “app”. It feels horribly stifling.

I can right-click on a link and get options that still keep me in the same app, like “Open link” or “Open Link in New Window.” To actually open the link in my web browser, I have to select “Copy Link”, then go to my web browser, open a new tab, and paste the link in there.

This is broken. I hope it isn’t intentional. Maybe I’m just at the receiving end of some weird glitch. If this stays this way, I’ll probably just remove the Safari-installed web apps from my dock. They feel pointless if they’re just roach motels.

I’d love to file a bug for this, but this isn’t a Webkit bug, it’s a Safari bug (and the Webkit bug tracker is at pains to point out that Webkit and Safari are not the same thing). But have you ever tried to file a bug with Apple? Good luck!

Anyway, I sincerely hope that this change will be walked back. Otherwise websites in the dock are dead in the water.

HTML web components

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.

Websites in the dock

I updated my Mac to the newest operating system, Sonoma. I did this to try out the new “add to Dock” feature in Safari. It’s like the “add to Homescreen” action on iOS.

Before I get into what’s good, I have to start by ranting about a big problem on both desktop and mobile: discovery.

First of all, you have to know that a square with an arrow sticking out of it means “share”.

Okay, I can buy it. It’s no better or worse than the three horizontal lines of a hamburger icon, or the three horizontal dots of a kebab icon. And whereas the hamburger and kebab icons are used as a catch-all cupboard to sweep all your rubbish into, at least this icon has a specific meaning. It means share, right?

Well, it used to. But now it’s also home to “add to Homescreen” and “add to Dock”. Neither of those actions are sharing.

Stretching semantics, I suppose you could say you’re sharing something with yourself.

Anyway, this is the biggest issue with progressive web apps on both iOS and Mac. Regardless of how well they work, there’s not much point if most people don’t know the option exists.

(Update: Jen rightly points out that you can also get to “add to Dock” from the file menu. Doh! How did I miss that‽)

Discovery aside, I was interested to see how Safari handles web apps on desktop compared to how Chrome does it.

I’ve had one or two web apps in my dock for a while, installed through Chrome. Google Meet is one of them. I use it quite a bit, and honestly it feels no different to using a native desktop app.

One annoyance is that the Chrome browser also automatically launches whenever I launch the Google Meet icon in my dock. This wouldn’t matter if Chrome were my default browser, but I use Firefox. So whenever I’m using the Google Meet web app, there’s a Google Chrome icon hanging around in my dock, saying “gizza job, I can do that.”

I opened Google Meet in Safari and then selected “add to Dock” from the square with an arrow sticking out of it. Then I quit Safari. I was delighted to see that when I launched the Google Meet web app from the dock, it didn’t automatically launch Safari! Excellent!

Even better, links within a Safari-installed web app respect your default browser choice. What I mean is, previously when I had Google Meet installed via Chrome, if I clicked an external link in Google Meet it opened in Chrome. But now with the Google Meet installed via Safari, external links open in Firefox, my browser of choice. Very good!

But the Safari-installed version of Google Meet is, alas, over-zealous with permissions. I have to grant access to my microphone and camera every single time I launch it. Previously—with the version installed via Chrome—it remembered my choice.

Now I don’t know if the behaviour in the Safari-installed version is a deliberate choice made for security reasons, or if it’s a bug. I suspect it’s a bug. After all, on iOS you get access to more permissions if a site is added to the homescreen—it’s the only way to ask for permissions for notifications, for example.

I added a few more sites to my dock: mastodon.social and thesession.org. They both work really well as standalone apps.

Interestingly, if I click a link to thesession.org from within the mastodon.social standalone web app (or the other way around), the link opens in my default browser. So the web apps don’t “own” the domains. That’s fine, although I wonder if it violates the principle of least surprise—perhaps the expectation is that the installed web app is the preffered owner of that link.

I also tried adding Google Calendar to my dock. Ironically, I can only do this with Safari. For some reason, Google have chosen not to make their calendar a progressive web app …which means there’s no option to install it from Google Chrome.

They’re missing a trick there. It’s the perfect candidate for being a standalone app.

Actually, I take that back. Gmail is the perfect candidate for being a standalone app …and yet it’s not a progressive web app. Very odd!

With Safari, you can add any website to the dock. It doesn’t need to be a progressive web app. But the installation experience works best if there’s a manifest file pointing to some nice icons.

As it turned out, Google Calendar runs like an absolute dog in Safari (and therefore as a Safari-installed web app). Before you cry conspiracy, note that it runs absolutely fine in Firefox. I know because I use it in Firefox every day. But I can’t add it to my dock from Firefox because Mozilla turned their back on progressive web apps a while back. A bad decision.

Google Calendar isn’t the only thing that runs slowly in Safari’s engine. This page on The Session has a very large DOM and a badly-coded in-page search (I know, I know, I need to improve it). It works fine in other browsers but Safari struggles mightily.

(Update: I tried using Google Calendar from Safari again and it seems to be running just fine now. Maybe I caught it on a bad day? In any case, I’ve added it to the dock now and it’s feeling good as a standalone app.)

Still, aside from a few annoying little things around permissions and performance—and the situation with discovery—it feels great to have websites that act just like other apps. I like that some of the icons in my dock are native, some are web apps, and I mostly don’t notice the difference.

I wonder if there’s much point using wrappers like Electron any more? I feel like they were mostly aiming to get that parity with native apps in having a standalone application launched from the dock.

Now all you need is a website.

Add view transitions to your website

I must admit, when Jake told me he was leaving Google, I got very worried about the future of the View Transitions API.

To recap: Chrome shipped support for the API, but only for single page apps. That had me worried:

If the View Transitions API works across page navigations, it could be the single best thing to happen to the web in years.

If the View Transitions API only works for single page apps, it could be the single worst thing to happen to the web in years.

Well, the multi-page version still hasn’t yet shipped in Chrome stable, but it is available in Chrome Canary behind a flag, so it looks like it’s almost here!

Robin took the words out of my mouth:

Anyway, even this cynical jerk is excited about this thing.

Are you the kind of person who flips feature flags on in nightly builds to test new APIs?

Me neither.

But I made an exception for the View Transitions API. So did Dave:

I think the most telling predictor for the success of the multi-page View Transitions API – compared to all other proposals and solutions that have come before it – is that I actually implemented this one. Despite animations being my bread and butter for many years, I couldn’t be arsed to even try any of the previous generation of tools.

Dave’s post is an excellent step-by-step introduction to using view transitions on your website. To recap:

Enable these two flags in Chrome Canary:

chrome://flags#view-transition
chrome://flags#view-transition-on-navigation

Then add this meta element to the head of your website:

<meta name="view-transition" content="same-origin">

You could stop there. If you navigate around your site, you’ll see that the navigations now fade in and out nicely from one page to another.

But the real power comes with transitioning page elements. Basically, you want to say “this element on this page should morph into that element on that page.” And when I say morph, I mean morph. As Dave puts it:

Behind the scenes the browser is rasterizing (read: making an image of) the before and after states of the DOM elements you’re transitioning. The browser figures out the differences between those two snapshots and tweens between them similar to Apple Keynote’s “Magic Morph” feature, the liquid metal T-1000 from Terminator 2: Judgement Day, or the 1980s cartoon series Turbo Teen.

If those references are lost on you, how about the popular kids book series Animorphs?

Some classic examples would be:

  • A thumbnail of a video on one page morphs into the full-size video on the next page.
  • A headline and snippet of an article on one page morphs into the full article on the next page.

I’ve added view transitions to The Session. Where I’ve got index pages with lists of titles, each title morphs into the heading on the next page.

Again, Dave’s post was really useful here. Each transition needs a unique name, so I used Dave’s trick of naming each transition with the ID of the individual item being linked to.

In the recordings section, for example, there might be a link like this on the index page:

<a href="/recordings/7812" style="view-transition-name: recording-7812">The Banks Of The Moy</a>

Which, if you click on it, takes you to the page with this heading:

<h1><span style="view-transition-name: recording-7812">The Banks Of The Moy</span></h1>

Why the span? Well, like Dave, I noticed some weird tweening happening between block and inline elements. Dave solved the problem with width: fit-content on the block-level element. I just stuck in an extra inline element.

Anyway, the important thing is that the name of the view transition matches: recording-7812.

I also added a view transition to pages that have maps. The position of the map might change from page to page. Now there’s a nice little animation as you move from one page with a map to another page with a map.

thesession.org View Transitions

That’s all good, but I found myself wishing that I could just have those enhancements. Every single navigation on the site was triggering a fade in and out—the default animation. I wondered if there was a way to switch off the default fading.

There is! That default animation is happening on a view transition named root. You can get rid of it with this snippet of CSS:

::view-transition-image-pair(root) {
  isolation: auto;
}
::view-transition-old(root),
::view-transition-new(root) {
  animation: none;
  mix-blend-mode: normal;
  display: block;
}

Voila! Now only the view transitions that you name yourself will get applied.

You can adjust the timing, the easing, and the animation properites of your view transitions. Personally, I was happy with the default morph.

In fact, that’s one of the things I like about this API. It’s another good example of declarative design. I say what I want to happen, but I don’t need to specify the details. I’ll let the browser figure all that out.

That’s what’s got me so excited about this API. Yes, it’s powerful. But just as important, it’s got a very low barrier to entry.

Chris has gathered a bunch of examples together in his post Early Days Examples of View Transitions. Have a look around to get some ideas.

If you like what you see, I highly encourage you to add view transitions to your website now.

“But wait,” I hear you cry, “this isn’t supported in any public-facing browser yet!”

To which, I respond “So what?” It’s a perfect example of progressive enhancement. Adding one meta element and a smidgen of CSS will do absolutely no harm to your website. And while no-one will see your lovely view transitions yet, once browsers do start shipping with support for the API, your site will automatically get better.

Your website will be enhanced. Progressively.

Update: Simon Pieters quite rightly warns against adding view transitions to live sites before the API is done:

in general, using features before they ship in a browser isn’t a great idea since it can poison the feature with legacy content that might break when the feature is enabled. This has happened several times and renames or so were needed.

Good point. I must temper my excitement with pragmatism. Let me amend my advice:

I highly encourage you to experiment with view transitions on your website now.

Read-only web apps

The most cartoonish misrepresentation of progressive enhancement is that it means making everything work without JavaScript.

No. Progressive enhancement means making sure your core functionality works without JavaScript.

In my book Resilient Web Design, I quoted Wilto:

Lots of cool features on the Boston Globe don’t work when JS breaks; “reading the news” is not one of them.

That’s an example where the core functionality is readily identifiable. It’s a newspaper. The core functionality is reading the news.

It isn’t always so straightforward though. A lot of services that self-identify as “apps” will claim that even their core functionality requires JavaScript.

Surely I don’t expect Gmail or Google Docs to provide core functionality without JavaScript?

In those particular cases, I actually do. I believe that a textarea in a form would do the job nicely. But I get it. That might take a lot of re-engineering.

So how about this compromise…

Your app should work in a read-only mode without JavaScript.

Without JavaScript I should still be able to read my email in Gmail, even if you don’t let me compose, reply, or organise my messages.

Without JavaScript I should still be able to view a document in Google Docs, even if you don’t let me comment or edit the document.

Even with something as interactive as Figma or Photoshop, I think I should still be able to view a design file without JavaScript.

Making this distinction between read-only mode and read/write mode could be very useful, especially at the start of a project.

Begin by creating the read-only mode that doesn’t require JavaScript. That alone will make for a solid foundation to build upon. Now you’ve built a fallback for any unexpected failures.

Now start adding the read/write functionally. You’re enhancing what’s already there. Progressively.

Heck, you might even find some opportunities to provide some read/write functionality that doesn’t require JavaScript. But if JavaScript is needed, that’s absolutely fine.

So if you’re about to build a web app and you’re pretty sure it requires JavaScript, why not pause and consider whether you can provide a read-only version.

Progressive disclosure with HTML

Robin penned a little love letter to the details element. I agree. It is a joyous piece of declarative power.

That said, don’t go overboard with it. It’s not a drop-in replacement for more complex widgets. But it is a handy encapsulation of straightforward progressive disclosure.

Just last week I added a couple of more details elements to The Session …kind of. There’s a bit of server-side conditional logic involved to determine whether details is the right element.

When you’re looking at a tune, one of the pieces of information you see is how many recordings there of that tune. Now if there are a lot of recordings, then there’s some additional information about which other tunes this one gets recorded with. That information is extra. Mere details, if you will.

You can see it in action on this tune listing. Thanks to the details element, the extra information is available to those who want it, but by default that information is tucked away—very handy for not clogging up that part of the page.

<details>
<summary>There are 181 recordings of this tune.</summary>
This tune has been recorded together with
<ul>
<li>…</li>
<li>…</li>
<li>…</li>
</ul>
</details>

Likewise, each tune page includes any aliases for the tune (in Irish music, the same tune can have many different titles—and the same title can be attached to many different tunes). If a tune has just a handful of aliases, they’re displayed in situ. But once you start listing out more than twenty names, it gets overwhelming.

The details element rides to the rescue once again.

Compare the tune I mentioned above, which only has a few aliases, to another tune that is known by many names.

Again, the main gist is immediately available to everyone—how many aliases are there? But if you want to go through them all, you can toggle that details element open.

You can effectively think of the summary element as the TL;DR of HTML.

<details>
<summary>There are 31 other names for this tune.</summary>
<p>Also known as…</p>

There’s another classic use of the details element: frequently asked questions. In the case of The Session, I’ve marked up the house rules and FAQs inside details elements, with the rule or question as the summary.

But there’s one house rule that’s most important (“Be civil”) so that details element gets an additional open attribute.

<details open>
<summary>Be civil</summary>
<p>Contributions should be constructive and polite, not mean-spirited or contributed with the intention of causing trouble.</p>

Push

Push notifications are finally arriving on iOS—hallelujah! Like I said last year, this is my number one wish for the iPhone, though not because I personally ever plan to use the feature:

When I’m evangelising the benefits of building on the open web instead of making separate iOS and Android apps, I inevitably get asked about notifications. As long as mobile Safari doesn’t support them—even though desktop Safari does—I’m somewhat stumped. There’s no polyfill for this feature other than building an entire native app, which is a bit extreme as polyfills go.

With push notifications in mobile Safari, the arguments for making proprietary apps get weaker. That’s good.

The announcement post is a bit weird though. It never uses the phrase “progressive web apps”, even though clearly the entire article is all about progressive web apps. I don’t know if this down to Not-Invented-Here syndrome by the Apple/Webkit team, or because of genuine legal concerns around using the phrase.

Instead, there are repeated references to “Home Screen apps”. This distinction makes some sense though. In order to use web push on iOS, your website needs to be added to the home screen.

I think that would be fair enough, if it weren’t for the fact that adding a website to the home screen remains such a hidden feature that even power users would be forgiven for not knowing about it. I described the steps here:

  1. Tap the “share” icon. It’s not labelled “share.” It’s a square with an arrow coming out of the top of it.
  2. A drawer pops up. The option to “add to home screen” is nowhere to be seen. You have to pull the drawer up further to see the hidden options.
  3. Now you must find “add to home screen” in the list
  • Copy
  • Add to Reading List
  • Add Bookmark
  • Add to Favourites
  • Find on Page
  • Add to Home Screen
  • Markup
  • Print

As long as this remains the case, we can expect usage of web push on iOS to be vanishingly low. Hardly anyone is going to add a website to their home screen when their web browser makes it so hard.

If you’d like to people to install your progressive web app, you’ll almost certainly need to prompt people to do so. Here’s the page I made on thesession.org with instructions on how to add to home screen. I link to it from the home page of the site.

I wish that pages like that weren’t necessary. It’s not the best user experience. But as long as mobile Safari continues to bury the home screen option, we don’t have much choice but to tackle this ourselves.

In between

I was chatting with my new colleague Alex yesterday about a link she had shared in Slack. It was the Nielsen Norman Group’s annual State of Mobile User Experience report.

There’s nothing too surprising in there, other than the mention of Apple’s app clips and Google’s instant apps.

Remember those?

Me neither.

Perhaps I lead a sheltered existence, but as an iPhone user, I don’t think I’ve come across a single app clip in the wild.

I remember when they were announced. I was quite worried about them.

See, the one thing that the web can (theoretically) offer that native can’t is instant access to a resource. Go to this URL—that’s it. Whereas for a native app, the flow is: go to this app store, find the app, download the app.

(I say that the benefit is theoretical because the website found at the URL should download quickly—the reality is that the bloat of “modern” web development imperils that advantage.)

App clips—and instant apps—looked like a way to route around the convoluted install process of native apps. That’s why I was nervous when they were announced. They sounded like a threat to the web.

In reality, the potential was never fulfilled (if my own experience is anything to go by). I wonder why people didn’t jump on app clips and instant apps?

Perhaps it’s because what they promise isn’t desirable from a business perspective: “here’s a way for users to accomplish their tasks without downloading your app.” Even though app clips can in theory be a stepping stone to installing the full app, from a user’s perspective, their appeal is the exact opposite.

Or maybe they’re just too confusing to understand. I think there’s an another technology that suffers from the same problem: progressive web apps.

Hear me out. Progressive web apps are—if done well—absolutely amazing. You get all of the benefits of native apps in terms of UX—they even work offline!—but you retain the web’s frictionless access model: go to a URL; that’s it.

So what are they? Are they websites? Yes, sorta. Are they apps? Yes, sorta.

That’s confusing, right? I can see how app clips and instant apps sound equally confusing: “you can use them straight away, like going to a web page, but they’re not web pages; they’re little bits of apps.”

I’m mostly glad that app clips never took off. But I’m sad that progressive web apps haven’t taken off more. I suspect that their fates are intertwined. Neither suffer from technical limitations. The problem they both face is inertia:

The technologies are the easy bit. Getting people to re-evaluate their opinions about technologies? That’s the hard part.

True of progressive web apps. Equally true of app clips.

But when I was chatting to Alex, she made me look at app clips in a different way. She described a situation where somebody might need to interact with some kind of NFC beacon from their phone. Web NFC isn’t supported in many browsers yet, so you can’t rely on that. But you don’t want to make people download a native app just to have a quick interaction. In theory, an app clip—or instant app—could do the job.

In that situation, app clips aren’t a danger to the web—they’re polyfills for hardware APIs that the web doesn’t yet support!

I love having my perspective shifted like that.

The specific situations that Alex and I were discussing were in the context of museums. Musuems offer such interesting opportunities for the physical and the digital to intersect.

Remember the pen from Cooper Hewitt? Aaron spoke about it at dConstruct 2014—a terrific presentation that’s well worth revisiting and absorbing.

The other dConstruct talk that’s very relevant to this liminal space between the web and native apps is the 2012 talk from Scott Jenson. I always thought the physical web initiative had a lot of promise, but it may have been ahead of its time.

I loved the thinking behind the physical web beacons. They were deliberately dumb, much like the internet itself. All they did was broadcast a URL. That’s it. All the smarts were to be found at the URL itself. That meant a service could get smarter over time. It’s a lot easier to update a website than swap out a piece of hardware.

But any kind of technology that uses Bluetooth, NFC, or other wireless technology has to get over the discovery problem. They’re invisible technologies, so by default, people don’t know they’re even there. But if you make them too discoverable— intrusively announcing themselves like one of the commercials in Minority Report—then they’re indistinguishable from spam. There’s a sweet spot of discoverability right in the middle that’s hard to get right.

Over the past couple of years—accelerated by the physical distancing necessitated by The Situation—QR codes stepped up to the plate.

They still suffer from some discoverability issues. They’re not human-readable, so you can’t be entirely sure that the URL you’re going to go to isn’t going to be a Rick Astley video. But they are visible, which gives them an advantage over hidden wireless technologies.

They’re cheaper too. Printing a QR code sticker costs less than getting a plastic beacon shipped from China.

QR codes turned out to be just good enough to bridge the gap between the physical and digital for those one-off interactions like dining outdoors during a pandemic:

I can see why they chose the web over a native app. Online ordering is the only way to place your order at this place. Telling people “You have to go to this website” …that seems reasonable. But telling people “You have to download this app” …that’s too much friction.

Ironically, the nail in the coffin for app clips and instant apps might’ve been hammered in by Apple and Google when they built QR-code recognition into their camera software.

Overloading buttons

It’s been almost two years since I added audio playback on The Session. The interface is quite straightforward. For any tune setting, there’s a button that says “play audio”. When you press that button, audio plays and the button’s text changes to “pause audio.”

By updating the button’s text like this, I’m updating the button’s accessible name. In other situations, where the button text doesn’t change, you can indicate whether a button is active or not by toggling the aria-pressed attribute. I’ve been doing that on the “share” buttons that act as the interface for a progressive disclosure. The label on the button—“share”—doesn’t change when the button is pressed. For that kind of progressive disclosure pattern, the button also has an aria-controls and aria-expanded attribute.

From all the advice I’ve read about button states, you should either update the accessible name or change the aria-pressed attribute, but not both. That would lead to the confusing situation of having a button labelled “pause audio” as having a state of “pressed” when in fact the audio is playing.

That was all fine until I recently added some more functionality to The Session. As well as being able to play back audio, you can now adjust the tempo of the playback speed. The interface element for this is a slider, input type="range".

But this means that the “play audio” button now does two things. It plays the audio, but it also acts as a progressive disclosure control, revealing the tempo slider. The button is simultaneously a push button for playing and pausing music, and a toggle button for showing and hiding another interface element.

So should I be toggling the aria-pressed attribute now, even though the accessible name is changing? Or is it enough to have the relationship defined by aria-controls and the state defined by aria-expanded?

Based on past experience, my gut feeling is that I’m probably using too much ARIA. Maybe it’s an anti-pattern to use both aria-expanded and aria-pressed on a progressive disclosure control.

I’m kind of rubber-ducking here, and now that I’ve written down what I’m thinking, I’m pretty sure I’m going to remove the toggling of aria-pressed in any situation where I’m already toggling aria-expanded.

What I really need to do is enlist the help of actual screen reader users. There are a number of members of The Session who use screen readers. I should get in touch and see if the new functionality makes sense to them.

No code

When I wrote about democratising dev, I made brief mention of the growing “no code” movement:

Personally, I would love it if the process of making websites could be democratised more. I’ve often said that my nightmare scenario for the World Wide Web would be for its fate to lie in the hands of an elite priesthood of programmers with computer science degrees. So I’m all in favour of no-code tools …in theory.

But I didn’t describe what no-code is, as I understand it.

I’m taking the term at face value to mean a mechanism for creating a website—preferably on a domain you control—without having to write anything in HTML, CSS, JavaScript, or any back-end programming language.

By that definition, something like WordPress.com (as opposed to WordPress itself) is a no-code tool:

Create any kind of website. No code, no manuals, no limits.

I’d also put Squarespace in the same category:

Start with a flexible template, then customize to fit your style and professional needs with our website builder.

And its competitor, Wix:

Discover the platform that gives you the freedom to create, design, manage and develop your web presence exactly the way you want.

Webflow provides the same kind of service, but with a heavy emphasis on marketing websites:

Your website should be a marketing asset, not an engineering challenge.

Bubble is trying to cover a broader base:

Bubble lets you create interactive, multi-user apps for desktop and mobile web browsers, including all the features you need to build a site like Facebook or Airbnb.

Wheras Carrd opts for a minimalist one-page approach:

Simple, free, fully responsive one-page sites for pretty much anything.

All of those tools emphasise that don’t need to need to know how to code in order to have a professional-looking website. But there’s a parallel universe of more niche no-code tools where the emphasis is on creativity and self-expression instead of slickness and professionalism.

neocities.org:

Create your own free website. Unlimited creativity, zero ads.

mmm.page:

Make a website in 5 minutes. Messy encouraged.

hotglue.me:

unique tool for web publishing & internet samizdat

I’m kind of fascinated by these two different approaches: professional vs. expressionist.

I’ve seen people grapple with this question when they decide to have their own website. Should it be a showcase of your achievements, almost like a portfolio? Or should it be a glorious mess of imagery and poetry to reflect your creativity? Could it be both? (Is that even doable? Or desirable?)

Robin Sloan recently published his ideas—and specs—for a new internet protocol called Spring ’83:

Spring ‘83 is a protocol for the transmission and display of something I am calling a “board”, which is an HTML fragment, limited to 2217 bytes, unable to execute JavaScript or load external resources, but otherwise unrestricted. Boards invite publishers to use all the richness of modern HTML and CSS. Plain text and blue links are also enthusiastically supported.

It’s not a no-code tool (you need to publish in HTML), although someone could easily provide a no-code tool to sit on top of the protocol. Conceptually though, it feels like it’s an a similar space to the chaotic good of neocities.org, mmm.page, and hotglue.me with maybe a bit of tilde.town thrown in.

It feels like something might be in the air. With Spring ’83, the Block protocol, and other experiments, people are creating some interesting small pieces that could potentially be loosely joined. No code required.

Web notifications on iOS

I’ve mentioned before that I don’t enable notifications on my phone. Text messages are the only exception. I don’t want to get notified if a new email arrives (I avoid email on my phone completely) and I certainly don’t want some social media app telling me somebody liked or faved something.

But the number one feature I’d like to see in Safari on iOS is web notifications.

It’s not for me personally, see. It’s because it’s the number one reason why people are choosing not to go all in progressive web apps.

Safari on iOS is the last holdout. But that equates to enough marketshare that many companies feel they can’t treat notifications as a progressive enhancement. While I may not agree with that decision myself, I get it.

When I’m evangelising the benefits of building on the open web instead of making separate iOS and Android apps, I inevitably get asked about notifications. As long as mobile Safari doesn’t support them—even though desktop Safari does—I’m somewhat stumped. There’s no polyfill for this feature other than building an entire native app, which is a bit extreme as polyfills go.

And of course, unlike on your Mac, you don’t have the option of using a different browser on your iPhone. As long as mobile Safari doesn’t support web notifications, nothing on iOS can support web notifications.

I’ve got progressive web apps on the home screen of my phone that match their native equivalents feature-for-feature. Twitter. Instagram. They’re really good. In some ways they’re superior to the native apps; the Twitter website is much calmer, and the Instagram website has no advertising. But if I wanted to get notifications from any of those sites, I’d have to keep the native apps installed just for that one feature.

So in the spirit of complaining about web browsers in a productive way, I just want to throw this plea out there: Apple, please support web notifications in mobile Safari!

The good news is that web notifications on iOS might be on their way. Huzzah!

Alas, we’re reliant on Maximiliano’s detective work to even get a glimpse of a future feature like this. Apple has no public roadmap for Safari. There’s this status page on the Webkit blog but it’s incomplete—web notifications don’t appear at all. In any case, WebKit and Safari aren’t the same thing. The only way of knowing if a feature might be implemented in Safari is if it shows up in Safari Technology Preview, at which point it’s already pretty far along.

So while my number one feature request for mobile Safari is web notifications, a close second would be a public roadmap.

It only seems fair. If Apple devrels are asking us developers what features we’d like to see implemented—as they should!—then shouldn’t those same developers also be treated with enough respect to share a roadmap with them? There’s not much point in us asking for features if, unbeknownst to us, that feature is already being worked on.

But, like I said, my number one request remains: web notifications on iOS …please!

A bug with progressive web apps on iOS

Dave recently wrote some good advice about what to do—and what not to do—when it comes to complaining about web browsers. I wrote something on this topic a little while back:

If there’s something about a web browser that you’re not happy with (or, indeed, if there’s something you’re really happy with), take the time to write it down and publish it

To summarise Dave’s advice, avoid conspiracy theories and snark; stick to specifics instead.

It’s very good advice that I should heed (especially the bit about avoiding snark). In that spirit, I’d like to document what I think is a bug on iOS.

I don’t need to name the specific browser, because there is basically only one browser allowed on iOS. That’s not snark; that’s a statement of fact.

This bug involves navigating from a progressive web app that has been installed on your home screen to an external web view.

To illustrate the bug, I’ll use the example of The Session. If you want to recreate the bug, you’ll need to have an account on The Session. Let me know if you want to set up a temporary account—I can take care of deleting it afterwards.

Here are the steps:

  1. Navigate to thesession.org in Safari on an iOS device.
  2. Add the site to your home screen.
  3. Open the installed site from your home screen—it will launch in standalone mode.
  4. Log in with your username and password.
  5. Using the site menu, navigate to the links section of the site.
  6. Click on any external link.
  7. After the external link opens in a web view, tap on “Done” to close the web view.

Expected behaviour: you are returned to the page you were on with no change of state.

Actual behaviour: you are returned to the page you were on but you are logged out.

So the act of visiting an external link in a web view while in a progressive web app in standalone mode seems to cause a loss of cookie-based authentication.

This isn’t permanent. Clicking on any internal link restores the logged-in state.

It is surprising though. My mental model for opening an external link in a web view is that it sits “above” the progressive web app, which remains in stasis “behind” it. But the page must actually be reloading, either when the web view is opened or when the web view is closed. And that reload is behaving like a fetch event without credentials.

Anyway, that’s my bug report. It may already be listed somewhere on the WebKit Bugzilla but I lack the deductive skills to find it. I’m not even sure if that’s the right place for this kind of bug. It might be specific to the operating system rather than the rendering engine.

This isn’t a high priority bug, but it is one of those cumulatively annoying software paper cuts.

Hope this helps!

Screenshots

I wrote about how I created a page on The Session with instructions for installing the site to your home screen. When I said that I included screenshots on that page, I may have underplayed the effort involved. It was real faff.

I’ve got an iPhone so generating screenshots (and video) from that wasn’t too bad. But I don’t have access to an Android phone. I found myself scouring the web for templates that I could use to mockup a screenshot of the address bar.

That got me thinking…

Wouldn’t it be cool if there were a service that generated those screenshots for you? You give it a URL, and it spits out screenshots of the site complete with overlays showing the installation flow on Android and iOS. It could even generate the img markup, complete with differently-scaled images for the srcset attribute.

Download the images. Copy that markup. Paste it into a page on your site. Boom! Now you’ve got somewhere to point your visitors to if you’d like them to install your progressive web app.

There are already some services out there for generating screenshots of mobile phones but they’re missing is the menu overlays for adding to home screen.

The devrels at both Google and Microsoft have been doing a great job of promoting progressive web apps. They’ve built tools to help you with tasks like generating icons or creating your web app manifest. It would be sooooo nifty if those tools also generated instructional screenshots for adding to home screen!

Installing progressive web apps

I don’t know about you, but it seems like everyone I follow on Twitter is playing Wordle. Although I don’t play the game myself, I think it’s pretty great.

Not only does Wordle have a very sweet backstory, but it’s also unashamedly on the web. If you want to play, you go to the URL powerlanguage.co.uk/wordle. That’s it. No need to download an app.

That hasn’t stopped some nefarious developers trying to trick people into downloading their clones of Wordle from app stores. App stores, which are meant to be curated and safe, are in fact filled with dodgy knock-offs and scams. Contrary to popular belief, the web is quite literally a safer bet.

Wordle has a web app manifest, which means you can add it to your home screen and it will behave just like a native app (although I don’t believe it has offline support). That’s great, but the process of adding a web app to your home screen on iOS is ludicrously long-winded.

Macworld published an article detailing how to get the real Wordle app on your iPhone or iPad. On the one hand it’s great to see this knowledge being spread. On the other hand it’s dispiriting that it’s even necessary to tell people that they can do this, like it’s a hidden nerdy secret just for power users.

At this point I’ve pretty much given up on Apple ever doing anything about this pathetic situation. So what can I do instead?

Well, taking my cue from that Macworld article, the least I can do is inform people how they can add a progressive web app to their home screen.

That’s what I’ve done on thesession.org. I’ve published a page on how to install The Session to your home screen.

On both Android and iPhone the journey to installing a progressive web app begins with incomprehensible iconography. On Android you must first tap on the unlabeled kebab icon—three vertical dots. On iOS you must first tap on the unlabeled share icon—a square with an arrow coming out of it.

The menu icon on Android. The share icon on iOS.

When it comes to mobile operating systems, consumer choice means you choose which kind of mystery meat to eat.

I’ve included screenshots to help people identify these mysterious portals. For iOS I’ve also included a video to illustrate the quest to find the secret menu item buried beneath the share icon.

I’ve linked to the page with the installation instructions from the site’s “help” page and the home page.

Handy tip: when you’re adding a start_url value to your web app manifest, it’s common to include a query string like this:

start_url: "/?homescreen"

I’m guessing most people to that so they can get analytics on how many people are starting from an icon tap. I don’t do analytics on The Session but I’m still using that query string in my start_url. On the home page of the site, I check for the existence of the query string. If it exists, I don’t show the link to the installation page. So once someone has installed the site to their home screen, they shouldn’t see that message when they launch The Session.

If you’ve got a progressive web app, it might be worth making a page with installation instructions rather than relying on browsers to proactively inform your site’s visitors. You’d still need to figure out the right time and place to point people to that page, but at least the design challenge would be in your hands.

Should you decide to take a leaf out of the Android and iOS playbooks and use mystery meat navigation to link to such a page, there’s an emoji you could potentially use: 📲

It’s still worse than using actual words, but it might be better than some random combination of dots, squares and arrows.

(I’m not really serious about using that emoji, but if you do, be sure to use a sensible aria-label value on the enclosing a element.)

Media queries with display-mode

It’s said that the best way to learn about something is to teach it. I certainly found that to be true when I was writing the web.dev course on responsive design.

I felt fairly confident about some of the topics, but I felt somewhat out of my depth when it came to some of the newer modern additions to browsers. The last few modules in particular were unexplored areas for me, with topics like screen configurations and media features. I learned a lot about those topics by writing about them.

Best of all, I got to put my new-found knowledge to use! Here’s how…

The Session is a progressive web app. If you add it to the home screen of your mobile device, then when you launch the site by tapping on its icon, it behaves just like a native app.

In the web app manifest file for The Session, the display-mode property is set to “standalone.” That means it will launch without any browser chrome: no address bar and no back button. It’s up to me to provide the functionality that the browser usually takes care of.

So I added a back button in the navigation interface. It only appears on small screens.

Do you see the assumption I made?

I figured that the back button was most necessary in the situation where the site had been added to the home screen. That only happens on mobile devices, right?

Nope. If you’re using Chrome or Edge on a desktop device, you will be actively encourged to “install” The Session. If you do that, then just as on mobile, the site will behave like a standalone native app and launch without any browser chrome.

So desktop users who install the progressive web app don’t get any back button (because in my CSS I declare that the back button in the interface should only appear on small screens).

I was alerted to this issue on The Session:

It downloaded for me but there’s a bug, Jeremy - there doesn’t seem to be a way to go back.

Luckily, this happened as I was writing the module on media features. I knew exactly how to solve this problem because now I knew about the existence of the display-mode media feature. It allows you to write media queries that match the possible values of display-mode in a web app manifest:

.goback {
  display: none;
}
@media (display-mode: standalone) {
  .goback {
    display: inline;
  }
}

Now the back button shows up if you “install” The Session, regardless of whether that’s on mobile or desktop.

Previously I made the mistake of inferring whether or not to show the back button based on screen size. But the display-mode media feature allowed me to test the actual condition I cared about: is this user navigating in standalone mode?

If I hadn’t been writing about media features, I don’t think I would’ve been able to solve the problem. It’s a really good feeling when you’ve just learned something new, and then you immediately find exactly the right use case for it!

Airport time

I went and spoke at an actual real live conference. As expected, it felt good …and weird. All at the same time.

It felt strange to be inside a building with other humans sharing an experience. At times it felt uncomfortable. The speaker’s dinner the night before the conference was lovely …and anxiety-inducing. Not just because it was my first time socialising in ages, but also just because it was indoors. I’ve been avoid indoor dining.

But the travel to Zürich all went smoothly. The airport wasn’t too busy. And on the airplane, everyone was dutifully masked up.

There’s definitely more paperwork and logistics involved in travelling overseas now. Jessica and I had to fill in our passenger locator forms for Switzerland and the UK. We also needed to pre-book a Covid test for two days after we got back. And we had to get a Covid test while we were in Switzerland so that we could show a negative result on returning to England. It doesn’t matter if you’re double-vaccinated; these tests are mandatory, which is totally fair.

Fortunately the conference organisers took care of booking those tests, which was great. On the first day of the conference I ducked out during the first break to go to the clinic next door and have a swab shoved up my nose. Ten minutes later I was handed a test result—negative!—complete with an official-looking stamp on it.

Two days later, after the conference was over, we had time to explore Zürich before heading to the airport to catch our evening flight. We had a very relaxing day which included a lovely boat trip out on the lake.

It was when we got to the airport that the relaxation ended.

We showed up at the airport in loads of time. I subscribe to the Craig Mod school of travel anyway, but given The Situation, I wanted to make sure we accounted for any extra time needed.

We went through security just fine and waited around for our gate to come up on the screen of gates and flights. Once we had a gate, we made our way there. We had to go through passport control but that didn’t take too long.

At the gate, there was a queue so—being residents of England—we immediately got in line. The airline was checking everyone’s paperwork.

When we got to the front of the line, we showed all our documents. Passport? Check. Boarding pass? Check. Passenger locator form? Check. Negative Covid result? Che …wait a minute, said the member of staff, this is in German. According to gov.uk, the test result needs to be in English, French, or Spanish.

I looked at the result. Apart from the heading at the top, all of the actual information was international: names, dates, and the test result itself said “neg.”

Not good enough.

My heart sank. “Call or email the clinic where you got the result. Get them to send you an English or French version” said the airline representative. Okay. We went off to the side and started doing that.

At this point there was still a good 40 or 50 minutes ’till the flight took off. We could sort this out.

I phoned the clinic. It was late Saturday afternoon and the clinic was closed. Shit!

Jessica and I went back to the gate agent we were dealing with and began pleading our case (in German …maybe that would help). She was very sympathetic but her hands were tied. Then she proposed a long shot. There was a Covid-testing centre in the airport. She would call them and tell them we were coming. But at this point it was 35 minutes until the flight left. We’d really have to leg it.

She scribbled down vague directions for where we had to go, and we immediately pelted off.

At this point I feel I should confess. I did not exhibit grace under pressure. I was, to put it mildy, freaking out.

Perhaps because I was the one selfishly indulging in panic, Jessica kept her head. She reminded me that we weren’t travelling to a conference—there wasn’t anywhere we had to be. Worst case scenario, we’d have to spend an extra night in Zürich and get a different flight tomorrow. She was right. I needed to hear that.

I was still freaking out though. We were running around like headless chickens trying to find where we needed to go. The instructions had left out the crucial bit of information that we actually needed to exit through passport control (temporarily re-entering Swiss territory) in order to get to the testing centre. Until we figured that out, we were just running hither and tither in a panic while the clock continued to count down.

It was a nightmare. I don’t mean that figuratively. I mean, I’m pretty sure I’ve had this exact nightmare. I’m in a building with a layout I don’t know and I need to get somewhere urgently but I don’t know how to get there.

Even the reason for this panicked situation felt like it had a dream logic to it. You know when you wake up from a bad dream and you examine the dream in retrospect and you realise it doesn’t actually make any sense? Well, that’s how this felt. You’ve got a negative test result but it needs it to be in one of these three languages …I mean, that sounds like the kind of nonsensical reasoning that should dissolve upon awakening.

Time was slipping away. Our flight leaves in twenty minutes.

Finally we realise that we need to go back through passport control. On the other side we run around some more until we spot the location that matches the vague description we’ve been given. There’s a sign! Covid testing centre!

We burst in through the doors. The gate agent had called ahead so we were expected. The young doctor on duty was cool as a cucumber. He must have to deal with this situation all day long. He calmly got us both to start filling in the appropriate online forms to pay for the tests, but instead of waiting for us to finish doing that, he started the testing straight away. Smart!

This felt like another nightmare I’ve had. I don’t mean having a swab shoved up my nose until it tickles my brain—that was probably the least uncomfortable part of this whole ordeal. I mean I need to fill out this web form accurately. On a touch screen device. And do it as quickly as possible!

Well, we did it. Filled in the forms, got the swabs. But now it was less than fifteen minutes until our flight time and we knew we still had to get back through passport control where there were lines of people.

“You’ll have the test results by email in ten minutes,” said the doctor. “Go!”

We sprinted out of there and went straight for the passport lines. Swallowing my pride, I went to the people at the end of a line. “Our flight leaves in ten minutes! Can we please cut in front!?”

“No.”

Right, next line. “Our flight leaves in…”

“Yes, yes! Go!”

“Thank you! Thank you so much!”

We repeated this craven begging until we got to the front of the line and gave our passports to the same guy who had orginally stamped them first time we came through. He was unfazed.

Then we ran back to the gate. Almost everyone had boarded by this point, but the gate was still open. Maybe we could actually make it!

But we still needed our test results. We both stood at the gate with our phones in hand, the email app open, frantically pulling to refresh.

The minutes were ticking by. At this point the flight departure time had arrived, but the gate agent said there was a slight delay. They could wait one or two minutes more.

Pull, refresh. Pull, refresh.

“I’ve got mine!” shouted Jessica. Half a minute later, mine showed up.

We showed the gate agent the results. She stamped whatever needed to be stamped and we were through.

I couldn’t believe it! Just 15 minutes ago I had been thinking we might as well give up—there was absolutely no way we were going to make it.

But here we were boarding the plane.

We got to our seats and strapped in. We were both quite sweaty and probably looked infectious …but we also had fresh proof that neither of had the ’rona.

We just sat there smiling, looking at each other, and shaking our heads. I just couldn’t believe we had actually made it.

The captain made an announcement. They were having a little technical difficulty with the plane’s system—no doubt the cause of the slight delay, luckily for us. They were going to reboot the system in the time-honoured fashion of turning it off and again.

The lights briefly went out and then came back on as the captain executed this manouvre.

Meanwhile Jessica and I were coming down from our adrenaline rush. Our breathing was beginning to finally slow down.

The captain’s voice came on again. That attempt at fixing the glitch hadn’t worked. So to play it safe, we were going to switch planes. The new plane would take off in an hour and a half from a different gate.

As the other passengers tutted and muttered noises of disapproval, Jessica and I just laughed. A delay? No problem!

But oh, the Alanis Morissette levels of irony! After all that stress at the mercy of the ticking clock, it turned out that time was in plentiful supply after all.

Everything after that proceeded without incident. We got on the replacement plane. We flew back to England. We breezed across the border and made our way home.

It felt good to be home.

Safari 15

If you download Safari Technology Preview you can test drive features that are on their way in Safari 15. One of those features, announced at Apple’s World Wide Developer Conference, is coloured browser chrome via support for the meta value of “theme-color.” Chrome on Android has supported this for a while but I believe Safari is the first desktop browser to add support. They’ve also added support for the media attribute on that meta element to handle “prefers-color-scheme.”

This is all very welcome, although it does remind me a bit of when Internet Explorer came out with the ability to make coloured scrollbars. I mean, they’re nice features’n’all, but maybe not the most pressing? Safari is still refusing to acknowledge progressive web apps.

That’s not quite true. In her WWDC video Jen demonstrates how you can add a progressive web app like Resilient Web Design to your home screen. I’m chuffed that my little web book made an appearance, but when you see how you add a site to your home screen in iOS, it’s somewhat depressing.

The steps to add a website to your home screen are:

  1. Tap the “share” icon. It’s not labelled “share.” It’s a square with an arrow coming out of the top of it.
  2. A drawer pops up. The option to “add to home screen” is nowhere to be seen. You have to pull the drawer up further to see the hidden options.
  3. Now you must find “add to home screen” in the list
  • Copy
  • Add to Reading List
  • Add Bookmark
  • Add to Favourites
  • Find on Page
  • Add to Home Screen
  • Markup
  • Print

It reminds of this exchange in The Hitchhiker’s Guide To The Galaxy:

“You hadn’t exactly gone out of your way to call attention to them had you? I mean like actually telling anyone or anything.”

“But the plans were on display…”

“On display? I eventually had to go down to the cellar to find them.”

“That’s the display department.”

“With a torch.”

“Ah, well the lights had probably gone.”

“So had the stairs.”

“But look you found the notice didn’t you?”

“Yes,” said Arthur, “yes I did. It was on display in the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying ‘Beware of The Leopard.’”

Safari’s current “support” for adding progressive web apps to the home screen feels like the minimum possible …just enough to use it as a legal argument if you happen to be litigated against for having a monopoly on app distribution. “Hey, you can always make a web app!” It’s true in theory. In practice it’s …suboptimal, to put it mildly.

Still, those coloured tab bars are very nice.

It’s a little bit weird that this stylistic information is handled by HTML rather than CSS. It’s similar to the meta viewport value in that sense. I always that the plan was to migrate that to CSS at some point, but here we are a decade later and it’s still very much part of our boilerplate markup.

Some people have remarked that the coloured browser chrome can make the URL bar look like part of the site so people might expect it to operate like a site-specific search.

I also wonder if it might blur “the line of death”; that point in the UI where the browser chrome ends and the website begins. Does the unified colour make it easier to spoof browser UI?

Probably not. You can already kind of spoof browser UI by using the right shade of grey. Although the removal any kind of actual line in Safari does give me pause for thought.

I tend not to think of security implications like this by default. My first thought tends to be more about how I can use the feature. It’s only after a while that I think about how bad actors might abuse the same feature. I should probably try to narrow the gap between those thoughts.

An email to The Guardian

Hello,

My name is Jeremy and I’ve been a paid subscriber to The Guardian for a few years now. But I’m considering cancelling my account after reading this editorial.

On the face of it, the headline of the article sound reasonable and hard to disagree with. But the substance of the article downplays anti-trans views as simply being “gender critical.” This is akin to describing segregationist views as “integration critical.”

This line is particularly egregious:

As a society, we need to resolve the question of how to protect the privacy, dignity and rights of trans women while also respecting the privacy, dignity and rights of those born female.

Setting up these positions as though one in any way invalidates the other gives oxygen to those who wish to paint someone’s identity as a threat. I’m very disappointed to see this viewpoint expressed in an editorial on The Guardian website.

Yours,

Jeremy Keith
