Progressing the web

Frances has written up some of the history behind her minting of the term “progressive web app”. She points out that accuracy is secondary to marketing:

I keep seeing folks (developers) getting all smart-ass saying they should have been PW “Sites” not “Apps” but I just want to put on the record that it doesn’t matter. The name isn’t for you and worrying about it is distraction from just building things that work better for everyone. The name is for your boss, for your investor, for your marketeer.

Personally, I think “progressive web app” is a pretty good phrase—two out of three words in it are spot on. I really like the word “progressive”, with its echoes of progressive enhancement. I really, really like the word “web”. But, yeah, I’m one of those smart-asses who points out that the “app” part isn’t great.

That’s not just me being a pedant (or, it’s not only me being a pedant). I’ve seen people who were genuinely put off investigating the technologies behind progressive web apps because of the naming.

Here’s an article with the spot-on title Progressive Web Apps — The Next Step In Responsive Web Design:

Late last week, Smashing Magazine, one of the largest and most influential online publications for web design, posted on Facebook that their website was “now running as a Progressive Web App.”

Honestly, I didn’t think much of it. Progressive Web Apps are for the hardcore web application developers creating the next online cloud-based Photoshop (complicated stuff), right? I scrolled on and went about my day.

And here’s someone feeling the cognitive dissonance of turning a website into a progressive web app, even though that’s exactly the right thing to do:

My personal website is a collection of static HTML files and is also a progressive web app. Transforming it into a progressive web app felt a bit weird in the beginning because it’s not an actual application but I wanted to be one of the cool kids, and PWAs still offer a lot of additional improvements.

Still, it could well be that these are the exceptions and that most people are not being discouraged by the “app” phrasing. I certainly hope that there aren’t more people out there thinking “well, progressive web apps aren’t for me because I’m building a content site.”

In short, the name might not be perfect but it’s pretty damn good.

What I find more troubling is the grouping of unrelated technologies under the “progressive web app” banner. If Google devrel events were anything to go by, you’d be forgiven for thinking that progressive web apps have something to do with AMP or Polymer (they don’t). One of the great things about progressive web apps is that they are agnostic to tech stacks. Still, I totally get why Googlers would want to use the opportunity to point to their other projects.

Far more troubling is the entanglement of the term “progressive web app” with the architectural choice of “single page app”. I’m not the only one who’s worried about this.

Here’s the most egregious example: an article on Hacker Noon called Before You Build a PWA You Need a SPA.

No! Not true! Literally any website can be a progressive web app:

That last step can be tricky if you’re new to service workers, but it’s not unsurmountable. It’s certainly a lot easier than completely rearchitecting your existing website to be a JavaScript-driven single page app.

Alas, I think that many of the initial poster-children for progressive web apps gave the impression that you had to make a completely separate app/site at a different URL. It was like a return to the bad old days of m. sites for mobile. The Washington Post’s progressive web app (currently offline) went so far as to turn away traffic from the “wrong” browsers. This is despite the fact that the very first item in the list of criteria for a progressive web app is:

Responsive: to fit any form factor

Now, I absolutely understand that the immediate priority is to demonstrate that a progressive web app can compete with a native mobile app in terms of features (and trounce it in terms of installation friction). But I’m worried that in our rush to match what native apps can do, we may end up ditching the very features that make the web a universally-accessible medium. Killing URLs simply because native apps don’t have URLs is a classic example of throwing the baby out with the bath water:

Up until now I’ve been a big fan of Progressive Web Apps. I understood them to be combining the best of the web (responsiveness, linkability) with the best of native (installable, connectivity independent). Now I see that balance shifting towards the native end of the scale at the expense of the web’s best features. I’d love to see that balance restored with a little less emphasis on the “Apps” and a little more emphasis on the “Web.” Now that would be progressive.

If the goal of the web is just to compete with native, then we’ve set the bar way too low.

So if you’ve been wary of investing the technologies behind progressive web apps because you’re “just” building a website, please try to see past the name. As Frances says:

It’s marketing, just like HTML5 had very little to do with actual HTML. PWAs are just a bunch of technologies with a zingy-new brandname.

Literally any website can—and should—be a progressive web app. Don’t let anyone tell you otherwise.

I was at an event last year where I heard Chris Heilmann say that you shouldn’t make your blog into a progressive web app. I couldn’t believe what I was hearing. He repeats that message in this video chat:

When somebody, for example, turns their blog into a PWA, I don’t see the point. I don’t want to have that icon on my homepage. This doesn’t make any sense to me.

Excuse me!? Just because you don’t want to have someone’s icon on your home screen, that person shouldn’t be using state-of-the-art technologies!? Excuse my French, but Fuck. That. Shit!

Our imaginations have become so limited by what native mobile apps currently do that we can’t see past merely imitating the status quo like a sad cargo cult.

I don’t want the web to equal native; I want the web to surpass it. I, for one, would prefer a reality where my home screen isn’t filled with the icons of startups and companies that have fulfilled the criteria of the gatekeepers. But a home screen filled with the faces of people who didn’t have to ask anyone’s permission to publish? That’s what I want!

Like Frances says:

Remember, this is for everyone.

One week to Patterns Day

Greetings!

Patterns Day is one week from today—Friday, June 30th. I’m really looking forward to seeing you in Brighton.

If you’re arriving by train, the venue is a short walk away from the train station. The Duke Of York’s Picture House is at Preston Circus. You’ll recognise the building by its distinctive pair of artificial can-can legs emerging from the roof.

http://tinyurl.com/patternsday

Registration starts at 9am. Show up with some ID, speak friend, and enter. Patterns Day is going to be a bit different to most conferences. Instead of getting a schwag bag and a name badge on a lanyard, you’re going to get a sticker to slap on yourself. The sticker identifies you as an attendee so please don’t lose it.

Once you’re registered, please help yourself to the free coffee, tea, and pastries. I’ll open up the show shortly before 10am with some introductory remarks, and then we’ll be all set for our first speaker at 10am. Here’s how the schedule is shaping up (but always subject to change):

https://adactio.com/journal/12409

There won’t be any conference WiFi. This is by design.

There’ll be a nice long lunch break from 12:30pm to 2pm. You’ll find plenty of tasty options in the neighbourhood. I’ve listed just a few on the Patterns Day website:

https://patternsday.com/#venue

There’ll be more coffee and tea throughout the day, and maybe a nice bag of popcorn in the afternoon.

We’ll finish up before 5pm, at which point we can collectively retire to a nearby pub to continue our discussions. Or we can head to the seafront to douse our melting brains in the English channel. Let’s play it by ear.

I can’t wait to welcome you to Patterns Day, and I’m positively aquiver with anticipation of the talks we’re going to hear from the fantastic line-up of speakers: Laura, Ellen, Sareh, Rachel, Alice, Jina, Paul, and Alla.

See you soon!

—Jeremy

The schedule for Patterns Day

There are only seventeen more days until Patterns Day. Squee!

I’ve got a plan now for how the day is going to run. Here’s the plan:

registration
opening remarks
Laura Elizabeth
Ellen deVries
break
Sareh Heidari
Rachel Andrew
lunch break
Alice Bartlett
Jina Anne
break
Paul Lloyd
Alla Kholmatova
closing remarks

There was a great response to my call for sponsors. Thanks to Amazon Video, we’ll have video recordings of all the talks. Thanks to Deliveroo, we’ll have coffee and tea throughout the day …and pastries in the morning! …and popcorn in the afternoon!!

You’re on your own for lunch. I’ve listed some options on the website, but I should add some more.

I have to say, looking at the schedule for the day, I’m very excited about this line-up. To say I’m looking forward to it would be quite the understatement. I can’t wait!

Talking with the tall man about poetry

When I started making websites in the 1990s, I had plenty of help. The biggest help came from the ability to view source on any web page—the web was a teacher of itself. I also got plenty of help from people who generously shared their knowledge and experience. There was Jeffrey’s Ask Dr. Web, Steve Champeon’s WebDesign-L mailing list, and Jeff Veen’s articles on Webmonkey. Years later, I was able to meet those people. That was a real privilege.

I’ve known Jeff for over a decade now. He’s gone from Adaptive Path to Google to TypeKit to Adobe to True Ventures, and it’s always fascinating to catch up with him and get his perspective on life, the universe, and everything.

He started up a podcast called Presentable about a year ago. It’s worth having a dig through the archives to have a listen to his chats with people like Andy, Jason, Anna, and Jessica. I was honoured when Jeff asked me to be on the show.

We ended up having a really good chat. It’s out now as Episode 25: The Tenuous Resilience of the Open Web. I really enjoyed having a good ol’ natter, and I hope you might enjoy listening to it.

‘Sfunny, but I feel like a few unplanned themes came up a few times. We ended up talking about art, but also about the scientific aspects of design. I couldn’t help but be reminded of the title of Jeff’s classic book, The Art and Science of Web Design.

We also talked about my most recent book, Resilient Web Design, and that’s when I noticed another theme. When discussing the web-first nature of publishing the book, I described the web version as the canonical version and all the other formats as copies that were generated from that. That sounds a lot like how I describe the indie web—something else we discussed—where you have the canonical instance on your own site but share copies on social networks: Publish on Own Site, Syndicate Elsewhere—POSSE.

We also talked about technologies, and it’s entirely possible that we sound like two old codgers on the front porch haranguing those damn kids on the lawn. You can be the judge of that. The audio is available for your huffduffing pleasure. If you enjoy listening to it half as much as I enjoyed doing it, then I enjoyed it twice as much as you.

eLife goes live

The World Wide Web was forged in the crucible of science. Tim Berners-Lee was working at CERN, the European Centre for Nuclear Research, a remarkable place where the pursuit of knowledge—rather than the pursuit of profit—is the driving force.

I often wonder whether the web as we know it—an open, decentralised system—could’ve been born anywhere else. These days it’s easy to focus on the success stories of the web in the worlds of commerce and social networking, but I still find there’s something that really “clicks” with the web and the science (Zooniverse being a classic example).

At Clearleft we’ve been lucky enough to work on science-driven projects like the Wellcome Library and the Wellcome Trust. It’s incredibly rewarding to work on projects where the bottom line is measured in knowledge-sharing rather than moolah. So when we were approached by eLife to help them with an upcoming redesign, we jumped at the chance.

We usually help organisations through our expertise in user-centred design, but in this case the design and UX were already in hand. The challenge was in the implementation. The team at eLife knew that they wanted a modular pattern library to keep their front-end components documented and easily reusable. Given Clearleft’s extensive experience with building pattern libraries, this was a match made in heaven (or whatever the scientific non-theistic equivalent of heaven is).

A group of us travelled up from Brighton to Cambridge to kick things off with a workshop. Before diving into code, it was important to set out the aims for the redesign, and figure out how a pattern library could best support those aims.

Right away, I was struck by the great working relationship between design and front-end development within eLife—there was a great collaborative spirit to the endeavour.

Some goals for the redesign soon emerged:

  • Promote the HTML reading experience as a 1st choice for readers.
  • Align the online experience with the eLife visual identity.

That led to some design principles:

  • Focus on content not site furniture.
  • Remove visual clutter and provide no more than the user needs at any stage of the experience.
  • Aid discovery of value added content beyond the manuscript.

Those design principles then informed the front-end development process. Together we came up with a priority of concerns:

  1. Access
  2. Maintainability
  3. Performance
  4. Taking advantage of browser capabilities
  5. Visual appeal

It’s interesting that maintainability was such a high priority that it superseded even performance, but we also proposed a hypothesis at the same time:

Maintainability doesn’t negatively impact performance.

The combination of the design principles and priorities led us to formulate approaches that could be used throughout the project:

  • Progressive enhancement.
  • Small-screen first responsive images.
  • Only add libraries as needed.

Then we dived into the tech stack: build tools, version control approaches, and naming methodologies. BEM was the winner there.

None of those decisions were set in stone, but they really helped to build a solid foundation for the work ahead. Graham camped out in Cambridge for a while, embedding himself in the team there as they began the process of identifying, naming, and building the components.

The work continued after Clearleft’s involvement wrapped up, and I’m happy to say that it all paid off. The new eLife site has just gone live. It’s looking—and performing—beautifully.

What a great combination: the best of the web and the best of science!

eLife is a non-profit organisation inspired by research funders and led by scientists. Our mission is to help scientists accelerate discovery by operating a platform for research communication that encourages and recognises the most responsible behaviours in science.

Month maps

One of the topics I enjoy discussing at Indie Web Camps is how we can use design to display activity over time on personal websites. That’s how I ended up with sparklines on my site—it was the a direct result of a discussion at Indie Web Camp Nuremberg a year ago:

During the discussion at Indie Web Camp, we started looking at how silos design their profile pages to see what we could learn from them. Looking at my Twitter profile, my Instagram profile, my Untappd profile, or just about any other profile, it’s a mixture of bio and stream, with the addition of stats showing activity on the site—signs of life.

Perhaps the most interesting visual example of my activity over time is on my Github profile. Halfway down the page there’s a calendar heatmap that uses colour to indicate the amount of activity. What I find interesting is that it’s using two axes of time over a year: days of the month across the X axis and days of the week down the Y axis.

I wanted to try something similar, but showing activity by time of day down the Y axis. A month of activity feels like the right range to display, so I set about adding a calendar heatmap to monthly archives. I already had the data I needed—timestamps of posts. That’s what I was already using to display sparklines. I wrote some code to loop over those timestamps and organise them by day and by hour. Then I spit out a table with days for the columns and clumps of hours for the rows.

Calendar heatmap on Dribbble

I’m using colour (well, different shades of grey) to indicate the relative amounts of activity, but I decided to use size as well. So it’s also a bubble chart.

It doesn’t work very elegantly on small screens: the table is clipped horizontally and can be swiped left and right. Ideally the visualisation itself would change to accommodate smaller screens.

Still, I kind of like the end result. Here’s last month’s activity on my site. Here’s the same time period ten years ago. I’ve also added month heatmaps to the monthly archives for my journal, links, and notes. They’re kind of like an expanded view of the sparklines that are shown with each month.

From one year ago, here’s the daily distribution of

And then here’s the the daily distribution of everything in that month all together.

I realise that the data being displayed is probably only of interest to me, but then, that’s one of the perks of having your own website—you can do whatever you feel like.

A workshop on evaluating technology

After hacking away at Indie Web Camp Düsseldorf, I stuck around for Beyond Tellerrand. I ended up giving a talk, stepping in for Ellen. I was a poor substitute, but I hope I entertained the lovely audience for 45 minutes.

After Beyond Tellerrand, I got on a train to Nuremberg …along with a dozen of my peers who were also at the event.

All aboard the Indie Web Train from Düsseldorf to Nürnberg. Indie Web Train.

I arrived right in the middle of Web Week Nürnberg. Among the many events going on was a workshop that Joschi arranged for me to run called Evaluating Technology. The workshop version of my Beyond Tellerrand talk, basically.

This was an evolution of a workshop I ran a while back. I have to admit, I was a bit nervous going into this. I had no tangible material prepared; no slides, no handouts, nothing. Instead the workshop is a collaborative affair. In order for it to work, the attendees needed to jump in and co-create it with me. Luckily for me, I had a fantastic and enthusiastic group of people at my workshop.

Evaluating Technology

We began with a complete braindump. “Name some tools and technologies,” I said. “Just shout ‘em out.” Shout ‘em out, they did. I struggled to keep up just writing down everything they said. This was great!

Evaluating Technology

The next step was supposed to be dot-voting on which technologies to cover, but there were so many of them, we introduced an intermediate step: grouping the technologies together.

Evaluating Technology Evaluating Technology

Once the technologies were grouped into categories like build tools, browser APIs, methodologies etc., we voted on which categories to cover, only then diving deeper into specific technologies.

I proposed a number of questions to ask of each technology we covered. First of all, who benefits from the technology? Is it a tool for designers and developers, or is it a tool for the end user? Build tools, task runners, version control systems, text editors, transpilers, and pattern libraries all fall into the first category—they make life easier for the people making websites. Browser features generally fall into the second category—they improve the experience for the end user.

Looking at user-facing technologies, we asked: how well do they fail? In other words, can you add this technology as an extra layer of enhancement on top of what you’re building or do you have to make it a foundational layer that’s potentially a single point of failure?

For both classes of technologies, we asked the question: what are the assumptions? What fundamental philosophy has been baked into the technology?

Evaluating Technology Evaluating Technology

Now, the point of this workshop is not for me to answer those questions. I have a limited range of experience with the huge amount of web technologies out there. But collectively all of us attending the workshop will have a good range of experience and knowledge.

Interesting then that the technologies people voted for were:

  • service workers,
  • progressive web apps,
  • AMP,
  • web components,
  • pattern libraries and design systems.

Those are topics I actually do have some experience with. Lots of the attendees had heard of these things, they were really interested in finding out more about them, but they hadn’t necessarily used them yet.

And so I ended up doing a lot of the talking …which wasn’t the plan at all! That was just the way things worked out. I was more than happy to share my opinions on those topics, but it was of a shame that I ended up monopolising the discussion. I felt for everyone having to listen to me ramble on.

Still, by the end of the day we had covered quite a few topics. Better yet, we had a good framework for categorising and evaluating web technologies. The specific technologies we covered were interesting enough, but the general approach provided the lasting value.

All in all, a great day with a great group of people.

Evaluating Technology

I’m already looking forward to running this workshop again. If you think it would be valuable for your company, get in touch.

Going offline at Indie Web Camp Düsseldorf

I’ve just come back from a ten-day trip to Germany. The trip kicked off with Indie Web Camp Düsseldorf over the course of a weekend.

IndieWebCamp Düsseldorf 2017

Once again the wonderful people at Sipgate hosted us in their beautiful building, and once again myself and Aaron helped facilitate the two days.

IndieWebCamp Düsseldorf 2017

Saturday was the BarCamp-like discussion day. Plenty of interesting topics were covered. I led a session on service workers, and that’s also what I decided to work on for the second day—that’s when the talking is done and we get down to making.

IndieWebCamp Düsseldorf 2017 IndieWebCamp Düsseldorf 2017 IndieWebCamp Düsseldorf 2017 IndieWebCamp Düsseldorf 2017

I like what Ethan is doing on his offline page. He shows a list of pages that have been cached, but instead of just listing URLs, he shows a title and description for each page.

I’ve already got a separate cache for pages that gets added to as the user browses around my site. I needed to figure out a way to store the metadata for those pages so that I could then display it on the offline page. I came up with a workable solution, and interestingly, it involved no changes to the service worker script at all.

When you visit any blog post, I put metadata about the page into localStorage (after first checking that there’s an active service worker):

if (navigator.serviceWorker && navigator.serviceWorker.controller) {
  window.addEventListener('load', function() {
    var data = {
      "title": "A minority report on artificial intelligence",
      "description": "Revisiting Spielberg’s films after a decade and a half.",
      "published": "May 7th, 2017",
      "timestamp": "1494171049"
    };
    localStorage.setItem(
      window.location.href,
      JSON.stringify(data)
    );
  });
}

In my case, I’m outputting the metadata from the server, but you could just as easily grab some from the DOM like this:

var data = {
  "title": document.querySelector("title").innerText,
  "description": document.querySelector("meta[name='description']").getAttribute("contents")
}

Meanwhile in my service worker, when you visit that same page, it gets added to a cache called “pages”. Both localStorage and the cache API are using URLs as keys. I take advantage of that on my offline page.

The nice thing about writing JavaScript on my offline page is that I know the page will only be seen by modern browsers that support service workers, so I can use all sorts of fancy from ES6, or whatever we’re calling it now.

I start by looping through the keys of the “pages” cache (that’s right—the cache API isn’t just for service workers; you can access it from any script). Then I check to see if there is a corresponding localStorage key with the same string (a URL). If there is, I pull the metadata out of local storage and add it to an array called browsingHistory:

const browsingHistory = [];
caches.open('pages')
.then( cache => {
  cache.keys()
  .then(keys => {
    keys.forEach( request => {
      let data = JSON.parse(localStorage.getItem(request.url));
        if (data) {
          data['url'] = request.url;
          browsingHistory.push(data);
      }
    });

Then I sort the list of pages in reverse chronological order:

browsingHistory.sort( (a,b) => {
  return b.timestamp - a.timestamp;
});

Now I loop through each page in the browsing history list and construct a link to each URL, complete with title and description:

let markup = '';
browsingHistory.forEach( data => {
  markup += `
<h2><a href="${ data.url }">${ data.title }</a></h2>
<p>${ data.description }</p>
<p class="meta">${ data.published }</p>
`;
});

Finally I dump the constructed markup into a waiting div in the page with an ID of “history”:

let container = document.getElementById('history');
container.insertAdjacentHTML('beforeend', markup);

All those steps need to be wrapped inside the then clause attached to caches.open("pages") because the cache API is asynchronous.

There you have it. Now if you’re browsing adactio.com and your network connection drops (or my server goes offline), you can choose from a list of pages you’ve previously visited.

The current situation isn’t ideal though. I’ve got a clean-up operation in my service worker to limit the number of items stored in my “pages” cache. The cache never gets bigger than 35 items. But there’s no corresponding clean-up of metadata stored in localStorage. So there could be a lot more bits of metadata in local storage than there are pages in the cache. It’s not harmful, but it’s a bit wasteful.

I can’t do a clean-up of localStorage from my service worker because service workers can’t access localStorage. There’s a very good reason for that: the localStorage API is synchronous, and everything that happens in a service worker needs to be asynchronous.

Service workers can access indexedDB: it’s asynchronous. I could use indexedDB instead of localStorage, but I’m not a masochist. My best bet would be to use the localForage library, which wraps indexedDB in the simple syntax of localStorage.

Maybe I’ll do that at the next Homebrew Website Club here in Brighton.

Sponsoring Patterns Day

It didn’t take long for Patterns Day to sell out (in the sense of the tickets all being sold; not in the sense of going mainstream and selling out to The Man).

I’m very pleased about the ticket situation. It certainly makes my life easier. Now I can concentrate on the logistics for the day, without having to worry about trying to flog tickets AKA marketing.

But I also feel bad. Some people who really, really wanted to come weren’t able to get tickets in time. This is usually because they work at a company where to have to get clearance for the time off, and the cost of the ticket. By the time the word came down from on high that they’ve got the green light, the tickets were already gone. That’s a real shame.

There is, however, a glimmer of hope on the horizon. There is one last chance to get tickets for Patterns Day, and that’s through sponsorship.

Here’s the deal: if I can get some things sponsored (like recordings of the talks, tea and coffee for the day, or an after-party), I can offer a few tickets in return. I can also offer your logo on the Patterns Day website, your logo on the slide between talks, and a shout-out on stage. But that’s pretty much it. I can’t offer a physical stand at the event—there just isn’t enough room. And I certainly can’t offer you a list of attendee details for your marketing list—that’s just wrong.

In order of priority, here’s what I would love to get sponsored, and here’s what I can offer in return:

  1. £2000: Sponsoring video recordings of the talks—4 tickets. This is probably the best marketing opportunity for your company; we can slap your logo at the start and end of each video when they go online.
  2. £2000: Sponsoring tea and coffee for attendees for the day—4 tickets. This is a fixed price, set by the venue.
  3. £2000+: Sponsoring an after-party near the conference—4 tickets. Ideally you’d take care of booking a venue for this, and you can go crazy decking it out with your branding. Two pubs right across from the conference venue have upstairs rooms you can book: The Joker, and The Hare And Hounds.

There you have it. There’s no room for negotiation, I’m afraid, but I think they’re pretty good deals. Remember, by sponsoring Patterns Day you’ll also have my undying gratitude, and the goodwill of all my peers coming to this event.

Reckon you can convince your marketing department? Drop me a line, let me know which sponsorship option you’d like to snap up, and those four tickets could be yours.

Patterns Day speakers

Ticket sales for Patterns Day are going quite, quite briskly. If you’d like to come along, but you don’t yet have a ticket, you might want to remedy that. Especially when you hear about who else is going to be speaking…

Sareh Heidari works at the BBC building websites for a global audience, in as many as twenty different languages. If you want to know about strategies for using CSS at scale, you definitely want to hear this talk. She just stepped off stage at the excellent CSSconf EU in Berlin, and I’m so happy that Sareh’s coming to Brighton!

Patterns Day isn’t the first conference about design systems and pattern libraries on the web. That honour goes to the Clarity conference, organised by the brilliant Jina Anne. I was gutted I couldn’t make it to Clarity last year. By all accounts, it was excellent. When I started to form the vague idea of putting on an event here in the UK, I immediately contacted Jina to make sure she was okay with it—I didn’t want to step on her toes. Not only was she okay with it, but she really wanted to come along to attend. Well, never mind attending, I said, how about speaking?

I couldn’t be happier that Jina agreed to speak. She has had such a huge impact on the world of pattern libraries through her work with the Lightning design system, Clarity, and the Design Systems Slack channel.

The line-up is now complete. Looking at the speakers, I find myself grinning from ear to ear—it’s going to be an honour to introduce each and every one of them.

This is going to be such an excellent day of fun and knowledge. I can’t wait for June 30th!

Styling the Patterns Day site

Once I had a design direction for the Patterns Day site, I started combining my marked-up content with some CSS. Ironically for an event that’s all about maintainability and reusability, I wrote the styles for this one-page site with no mind for future use. I treated the page as a one-shot document. I even used ID selectors—gasp! (the IDs were in the HTML anyway as fragment identifiers).

The truth is I didn’t have much of a plan. I just started hacking away in a style element in the head of the document, playing around with colour, typography, and layout.

I started with the small-screen styles. That wasn’t a conscious decision so much as just the way I do things automatically now. When it came time to add some layout for wider viewports, I used a sprinkling of old-fashioned display: inline-block so that things looked so-so. I knew I wanted to play around with Grid layout so the inline-block styles were there as fallback for non-supporting browsers. Once things looked good enough, the fun really started.

I was building the site while I was in Seattle for An Event Apart. CSS Grid layout was definitely a hot topic there. Best of all, I was surrounded by experts: Jen, Rachel, and Eric. It was the perfect environment for me to dip my toes into the waters of grid.

Jen was very patient in talking me through the concepts, syntax, and tools for using CSS grids. Top tip: open Firefox’s inspector, select the element with the display:grid declaration, and click the “waffle” icon—instant grid overlay!

For the header of the Patterns Day site, I started by using named areas. That’s the ASCII-art approach. I got my head around it and it worked okay, but it didn’t give me quite the precision I wanted. I switched over to using explicit grid-row and grid-column declarations.

It’s definitely a new way of thinking about layout: first you define the grid, then you place the items on it (rather than previous CSS layout systems where each element interacted with the elements before and after). It was fun to move things around and not have to worry about the source order of the elements …as long as they were direct children of the element with display:grid applied.

Without any support for sub-grids, I ended up having to nest two separate grids within one another. The logo is a grid parent, which is inside the header, also a grid parent. I managed to get things to line up okay, but I think this might be a good use case for sub-grids.

The logo grid threw up some interesting challenges. I wanted each letter of the words “Patterns Day” to be styleable, but CSS doesn’t give us any way to target individual letters other than :first-letter. I wrapped each letter in a b element, made sure that they were all wrapped in an element with an aria-hidden attribute (so that the letters wouldn’t be spelled out), and then wrapped that in an element with an aria-label of “Patterns Day.” Now I could target those b elements.

For a while, I also had a br element (between “Patterns” and “Day”). That created some interesting side effects. If a br element becomes a grid item, it starts to behave very oddly: you can apply certain styles but not others. Jen and Eric then started to test other interesting elements, like hr. There was much funkiness and gnashing of specs.

It was a total nerdfest, and I loved every minute of it. This is definitely the most excitement I’ve felt around CSS for a while. It feels like a renaissance of zen gardens and layout reservoirs (kids, ask your parents).

After a couple of days playing around with grid, I had the Patterns Day site looking decent enough to launch. I dabbled with some other fun CSS stuff in there too, like gratuitous clip paths and filters when hovering over the speaker images, and applying shape-outside with an image mask.

Go ahead and view source on the Patterns Day page if you want—I ended up keeping all the CSS in the head of the document. That turned out to be pretty good for performance …for first-time visits anyway. But after launching the site, I couldn’t resist applying some more performance tweaks.

Designing the Patterns Day site

Patterns Day is not one of Clearleft’s slick’n’smooth conferences like dConstruct or UX London. It’s more of a spit’n’sawdust affair, like Responsive Day Out.

You can probably tell from looking at the Patterns Day website that it wasn’t made by a crack team of designers and developers—it’s something I threw together over the course of a few days. I had a lot of fun doing it.

I like designing in the browser. That’s how I ended up designing Resilient Web Design, The Session, and Huffduffer back in the day. But there’s always the initial problem of the blank page. I mean, I had content to work with (the information about the event), but I had no design direction.

My designery colleagues at Clearleft were all busy on client projects so I couldn’t ask any of them to design a website, but I thought perhaps they’d enjoy a little time-limited side exercise in producing ideas for a design direction. Initially I was thinking they could all get together for a couple of hours, lock themselves in a room, and bash out some ideas as though it were a mini hack farm. Coordinating calendars proved too tricky for that. So Jon came up with an alternative: a baton relay.

Remember Layer Tennis? I once did the commentary for a Layer Tennis match and it was a riot—simultaneously terrifying and rewarding.

Anyway, Jon suggested something kind of like that, but instead of a file being batted back and forth between two designers, the file would passed along from designer to designer. Each designer gets one art board in a Sketch file. You get to see what the previous designers have done, leaving you to either riff on that or strike off in a new direction.

The only material I supplied was an early draft of text for the website, some photos of the first confirmed speakers, and some photos I took of repeating tiles when I was in Porto (patterns, see?). I made it clear that I wasn’t looking for pages or layouts—I was interested in colour, typography, texture and “feel.” Style tiles, yes; comps, no.

Jon

Jon’s art board.

Jon kicks things off and immediately sets the tone with bright, vibrant colours. You can already see some elements that made it into the final site like the tiling background image of shapes, and the green-bordered text block. There are some interesting logo ideas in there too, some of them riffing on LEGO, others riffing on illustrations from Christopher Alexander’s book, A Pattern Language. Then there’s the typeface: Avenir Next. I like it.

James G

James G’s art board.

Jimmy G is up next. He concentrates on the tiles idea. You can see some of the original photos from Porto in the art board, alongside his abstracted versions. I think they look great, and I tried really hard to incorporate them into the site, but I couldn’t quite get them to sit with the other design elements. Looking at them now, I still want to get them into the site …maybe I’ll tinker with the speaker portraits to get something more like what James shows here.

Ed

Ed’s art board.

Ed picks up the baton and immediately iterates through a bunch of logo ideas. There’s something about the overlapping text that I like, but I’m not sure it fits for this particular site. I really like the effect of the multiple borders though. With a bit more time, I’d like to work this into the site.

James B

Batesy’s art board.

Batesy is the final participant. He has some other nice ideas in there, like the really subtle tiling background that also made its way into the final site (but I’ll pass on the completely illegible text on the block of bright green). James works through two very different ideas for the logo. One of them feels a bit too busy and chaotic for me, but the other one …I like it a lot.

I immediately start thinking “Hmm …how could I make this work in a responsive way?” This is exactly the impetus I needed. At this point I start diving into CSS. Not only did I have some design direction, I’m champing at the bit to play with some of these ideas. The exercise was a success!

Feel free to poke around the Patterns Day site. And while you’re there, pick up a ticket for the event too.

Announcing Patterns Day: June 30th

Gather ‘round, my friends. I’ve got a big announcement.

You should come to Brighton on Friday, June 30th. Why? Well, apart from the fact that you can have a lovely Summer weekend by the sea, that’s when a brand new one-day event will be happening:

Patterns Day!

That’s right—a one-day event dedicated to all things patterny: design systems, pattern libraries, style guides, and all that good stuff. I’m putting together a world-class line-up of speakers. So far I’ve already got:

It’s going to be a brain-bendingly good day of ideas, case studies, processes, and techniques with something for everyone, whether you’re a designer, developer, product owner, content strategist, or project manager.

Best of all, it’s taking place in the splendid Duke Of York’s Picture House. If you’ve been to Remy’s FFconf then you’ll know what a great venue it is—such comfy, comfy seats! Well, Patterns Day will be like a cross between FFconf and Responsive Day Out.

Tickets are £150+VAT. Grab yours now. Heck, bring the whole team. Let’s face it, this is a topic that everyone is struggling with so we’re all going to benefit from getting together for a day with your peers to hammer out the challenges of pattern libraries and design systems.

I’m really excited about this! I would love to see you in Brighton on the 30th of June for Patterns Day. It’s going to be fun!

Getting griddy with it

I had the great pleasure of attending An Event Apart Seattle last week. It was, as always, excellent.

It’s always interesting to see themes emerge during an event, especially when those thematic overlaps haven’t been planned in advance. Jen noticed this one:

I remember that being a theme at An Event Apart San Francisco too, when it seemed like every speaker had words to say about ill-judged use of Bootstrap. That theme was certainly in my presentation when I talked about “the fallacy of assumed competency”:

  1. large company X uses technology Y,
  2. company X must know what they are doing because they are large,
  3. therefore technology Y must be good.

Perhaps “the fallacy of assumed suitability” would be a better term. Heydon calls it “the ‘made at Facebook’ fallacy.” But I also made sure to contrast it with the opposite extreme: “Not Invented Here syndrome”.

As well as over-arching themes, it was also interesting to see which technologies were hot topics at An Event Apart. There was one clear winner here—CSS Grid Layout.

Microsoft—a sponsor of the event—used An Event Apart as the place to announce that Grid is officially moving into development for Edge. Jen talked about Grid (of course). Rachel talked about Grid (of course). And while Eric and Una didn’t talk about it on stage, they’ve both been writing about the fun they’ve been having having with Grid. Una wrote about 3 CSS Grid Features That Make My Heart Flutter. Eric is documenting the overall of his site with Grid. So when we were all gathered together, that’s what we were nerding out about.

The CSS Squad.

There are some great resources out there for levelling up in Grid-fu:

With Jen’s help, I’ve been playing with CSS Grid on a little site that I’m planning to launch tomorrow (he said, foreshadowingly). I took me a while to get my head around it, but once it clicked I started to have a lot of fun. “Fun” seems to be the overall feeling around this technology. There’s something infectious about the excitement and enthusiasm that’s returning to the world of layout on the web. And now that the browser support is great pretty much across the board, we can start putting that fun into production.

Code (p)reviews

I’m not a big fan of job titles. I’ve always had trouble defining what I do as a noun—I much prefer verbs (“I make websites” sounds fine, but “website maker” sounds kind of weird).

Mind you, the real issue is not finding the right words to describe what I do, but rather figuring out just what the heck it is that I actually do in the first place.

According to the Clearleft website, I’m a technical director. That doesn’t really say anything about what I do. To be honest, I tend to describe my work these days in terms of what I don’t do: I don’t tend to write a lot of HTML, CSS, and JavaScript on client projects (although I keep my hand in with internal projects, and of course, personal projects).

Instead, I try to make sure that the people doing the actual coding—Mark, Graham, and Danielle—are happy and have everything they need to get on with their work. From outside, it might look like my role is managerial, but I see it as the complete opposite. They’re not in service to me; I’m in service to them. If they’re not happy, I’m not doing my job.

There’s another aspect to this role of technical director, and it’s similar to the role of a creative director. Just as a creative director is responsible for the overall direction and quality of designs being produced, I have an oversight over the quality of front-end output. I don’t want to be a bottleneck in the process though, and to be honest, most of the time I don’t do much checking on the details of what’s being produced because I completely trust Mark, Graham, and Danielle to produce top quality code.

But I feel I should be doing more. Again, it’s not that I want to be a bottleneck where everything needs my approval before it gets delivered, but I hope that I could help improve everyone’s output.

Now the obvious way to do this is with code reviews. I do it a bit, but not nearly as much as I should. And even when I do, I always feel it’s a bit late to be spotting any issues. After all, the code has already been written. Also, who am I to try to review the code produced by people who are demonstrably better at coding than I am?

Instead I think it will be more useful for me to stick my oar in before a line of code has been written; to sit down with someone and talk through how they’re going to approach solving a particular problem, creating a particular pattern, or implementing a particular user story.

I suppose it’s really not that different to rubber ducking. Having someone to talk out loud with about potential solutions can be really valuable in my experience.

So I’m going to start doing more code previews. I think it will also incentivise me to do more code reviews—being involved in the initial discussion of a solution means I’m going to want to see the final result.

But I don’t think this should just apply to front-end code. I’d also like to exercise this role as technical director with the designers on a project.

All too often, decisions are made in the design phase that prove problematic in development. It usually works out okay, but it often means revisiting the designs in light of some technical considerations. I’d like to catch those issues sooner. That means sticking my nose in much earlier in the process, talking through what the designers are planning to do, and keeping an eye out for any potential issues.

So, as technical director, I won’t be giving feedback like “the colour’s not working for me” or “not sure about those type choices” (I’ll leave that to the creative director), but instead I can ask questions like “how will this work without hover?” or “what happens when the user does this?” as well as pointing out solutions that might be tricky or time-consuming to implement from a technical perspective.

What I want to avoid is the swoop’n’poop, when someone seagulls in after something has been designed or built and points out all the problems. The earlier in the process any potential issues can be spotted, the better.

And I think that’s my job.

Progressive Web App questions

I got a nice email recently from Colin van Eenige. He wrote:

For my graduation project I’m researching the development of Progressive Web Apps and found your offline book called resilient web design. I was very impressed by the implementation of the website and it really was a nice experience.

I’m very interested in your vision on progressive web apps and what capabilities are waiting for us regarding offline content. Would it be fine if I’d send you some questions?

I said that would be fine, although I couldn’t promise a swift response. He sent me four questions. I finally got ‘round to sending my answers…

1. https://resilientwebdesign.com/ is an offline web book (progressive web app). What was the primary reason make it available like this (besides the other formats)?

Well, given the subject matter, it felt right that the canonical version of the book should be not just online, but made with the building blocks of the web. The other formats are all nice to have, but the HTML version feels (to me) like the “real” book.

Interestingly, it wasn’t too much trouble for people to generate other formats from the HTML (ePub, MOBI, PDF), whereas I think trying to go in the other direction would be trickier.

As for the offline part, that felt like a natural fit. I had already done that with a previous book of mine, HTML5 For Web Designers, which I put online a year or two after its print publication. In that case, I used AppCache for the offline functionality. AppCache is horrible, but this use case might be one of the few where it works well: a static book that’s never going to change. Cache invalidation is one of the worst parts of using AppCache so by not having any kinds of updates at all, I dodged that bullet.

But when it came time for Resilient Web Design, a service worker was definitely the right technology. Still, I’ve got AppCache in there as well for the browsers that don’t yet support service workers.

2. What effect you you think Progressive Web Apps will have on content consuming and do you think these will take over the purpose of some Native Apps?

The biggest effect that service workers could have is to change the expectations that people have about using the web, especially on mobile devices. Right now, people associate the web on mobile with long waits and horrible spammy overlays. Service workers can help solve that first part.

If people then start adding sites to their home screen, that will be a great sign that the web is really holding its own. But I don’t think we should get too optimistic about that: for a user, there’s no difference between a prompt on their screen saying “add to home screen” and a prompt on their screen saying “download our app”—they’re equally likely to be dismissed because we’ve trained people to dismiss anything that covers up the content they actually came for.

It’s entirely possible that websites could start taking over much of the functionality that previously was only possible in a native app. But I think that inertia and habit will keep people using native apps for quite some time.

The big exception is in markets where storage space on devices is in short supply. That’s where the decision to install a native app isn’t taken likely (given the choice between your family photos and an app, most people will reject the app). The web can truly shine here if we build lightweight, performant services.

Even in that situation, I’m still not sure how many people will end up adding those sites to their home screen (it might feel so similar to installing a native app that there may be some residual worry about storage space) but I don’t think that’s too much of a problem: if people get to a site via search or typing, that’s fine.

I worry that the messaging around “progressive web apps” is perhaps over-fetishising the home screen. I don’t think that’s the real battleground. The real battleground is in people’s heads; how they perceive the web and how they perceive native.

After all, if the average number of native apps installed in a month is zero, then that’s not exactly a hard target to match. :-)

3. What is your vision regarding Progressive Web Apps?

For me, progressive web apps don’t feel like a separate thing from making websites. I worry that the marketing of them might inflate expectations or confuse people. I like the idea that they’re simply websites that have taken their vitamins.

So my vision for progressive web apps is the same as my vision for the web: something that people use every day for all sorts of tasks.

I find it really discouraging that progressive web apps are becoming conflated with single page apps and the app shell model. Those architectural decisions have nothing to do with service workers, HTTPS, and manifest files. Yet I keep seeing the concepts used interchangeably. It would be a real shame if people chose not to use these great technologies just because they don’t classify what they’re building as an “app.”

If anything, it’s good ol’ fashioned content sites (newspapers, wikipedia, blogs, and yes, books) that can really benefit from the turbo boost of service worker+HTTPS+manifest.

I was at a conference recently where someone was given a talk encouraging people to build progressive web apps but discouraging people from doing it for their own personal sites. That’s a horrible, elitist attitude. I worry that this attitude is being codified in the term “progressive web app”.

4. What is the biggest learning you’ve had since working on Progressive Web Apps?

Well, like I said, I think that some people are focusing a bit too much on the home screen and not enough on the benefits that service workers can provide to just about any website.

My biggest learning is that these technologies aren’t for a specific subset of services, but can benefit just about anything that’s on the web. I mean, just using a service worker to explicitly cache static assets like CSS, JS, and some images is a no-brainer for almost any project.

So there you go—I’m very excited about the capabilities of these technologies, but very worried about how they’re being “sold”. I’m particularly nervous that in the rush to emulate native apps, we end up losing the very thing that makes the web so powerful: URLs.

Empire State

I’m in New York. Again. This time it’s for Google’s AMP Conf, where I’ll be giving ‘em a piece of my mind on a panel.

The conference starts tomorrow so I’ve had a day or two to acclimatise and explore. Seeing as Google are footing the bill for travel and accommodation, I’m staying at a rather nice hotel close to the conference venue in Tribeca. There’s live jazz in the lounge most evenings, a cinema downstairs, and should I request it, I can even have a goldfish in my room.

Today I realised that my hotel sits in the apex of a triangle of interesting buildings: carrier hotels.

32 Avenue Of The Americas.Telephone wires and radio unite to make neighbors of nations

Looming above my hotel is 32 Avenue of the Americas. On the outside the building looks like your classic Gozer the Gozerian style of New York building. Inside, the lobby features a mosaic on the ceiling, and another on the wall extolling the connective power of radio and telephone.

The same architects also designed 60 Hudson Street, which has a similar Art Deco feel to it. Inside, there’s a cavernous hallway running through the ground floor but I can’t show you a picture of it. A security guard told me I couldn’t take any photos inside …which is a little strange seeing as it’s splashed across the website of the building.

60 Hudson.HEADQUARTERS The Western Union Telegraph Co. and telegraph capitol of the world 1930-1973

I walked around the outside of 60 Hudson, taking more pictures. Another security guard asked me what I was doing. I told her I was interested in the history of the building, which is true; it was the headquarters of Western Union. For much of the twentieth century, it was a world hub of telegraphic communication, in much the same way that a beach hut in Porthcurno was the nexus of the nineteenth century.

For a 21st century hub, there’s the third and final corner of the triangle at 33 Thomas Street. It’s a breathtaking building. It looks like a spaceship from a Chris Foss painting. It was probably designed more like a spacecraft than a traditional building—it’s primary purpose was to withstand an atomic blast. Gone are niceties like windows. Instead there’s an impenetrable monolith that looks like something straight out of a dystopian sci-fi film.

33 Thomas Street.33 Thomas Street, New York

Brutalist on the outside, its interior is host to even more brutal acts of invasive surveillance. The Snowden papers revealed this AT&T building to be a centrepiece of the Titanpointe programme:

They called it Project X. It was an unusually audacious, highly sensitive assignment: to build a massive skyscraper, capable of withstanding an atomic blast, in the middle of New York City. It would have no windows, 29 floors with three basement levels, and enough food to last 1,500 people two weeks in the event of a catastrophe.

But the building’s primary purpose would not be to protect humans from toxic radiation amid nuclear war. Rather, the fortified skyscraper would safeguard powerful computers, cables, and switchboards. It would house one of the most important telecommunications hubs in the United States…

Looking at the building, it requires very little imagination to picture it as the lair of villainous activity. Laura Poitras’s short film Project X basically consists of a voiceover of someone reading an NSA manual, some ominous background music, and shots of 33 Thomas Street looming in its oh-so-loomy way.

A top-secret handbook takes viewers on an undercover journey to Titanpointe, the site of a hidden partnership. Narrated by Rami Malek and Michelle Williams, and based on classified NSA documents, Project X reveals the inner workings of a windowless skyscraper in downtown Manhattan.

Small steps

The new Clearleft website is live! Huzzah!

Many people have been working very hard on it and it’s all looking rather nice. But, as I said before, the site launch isn’t the end—it’s just the beginning.

There are some obvious next steps: fixing bugs, adding content, tweaking copy, and, oh yeah, that whole “testing with real users” thing. But there’s also an opportunity to have some fun on the front end. Now that the site is out there in the wild, there’s a real incentive to improve its performance.

Off the top of my head, these are some areas where I think we can play around:

  • Font loading. Right now the site is just using @font-face. A smart font-loading strategy—at least for the body copy—could really help improve the perceived performance.
  • Responsive images. A long-term solution will require some wrangling on the back end, but I reckon we can come up with some way of generating different sized images to reference in srcset.
  • Service worker. It’s a no-brainer. Now that the Clearleft site is (finally!) running on HTTPS, having a simple service worker to cache static assets like CSS, JavaScript and some images seems like the obvious next step. The question is: what other offline shenanigans could we get up to?

I’m looking forward to tinkering with some of those technologies. Each one should make an incremental improvement to the site’s performance. There are already some steps on the back-end that are making a big difference: upgrading to PHP7 and using HTTP2.

Now the real fun begins.

Long betting

It has been exactly six years to the day since I instantiated this prediction:

The original URL for this prediction (www.longbets.org/601) will no longer be available in eleven years.

It is exactly five years to the day until the prediction condition resolves to a Boolean true or false.

If it resolves to true, The Bletchly Park Trust will receive $1000.

If it resolves to false, The Internet Archive will receive $1000.

Much as I would like Bletchley Park to get the cash, I’m hoping to lose this bet. I don’t want my pessimism about URL longevity to be rewarded.

So, to recap, the bet was placed on

02011-02-22

It is currently

02017-02-22

And the bet times out on

02022-02-22.

Amber

I really enjoyed teaching in Porto last week. It was like having a week-long series of CodeBar sessions.

Whenever I’m teaching at CodeBar, I like to be paired up with people who are just starting out. There’s something about explaining the web and HTML from first principles that I really like. And people often have lots and lots of questions that I enjoy answering (if I can). At CodeBar—and at The New Digital School—I found myself saying “Great question!” multiple times. The really great questions are the ones that I respond to with “I don’t know …let’s find out!”

CodeBar is always a very rewarding experience for me. It has given me the opportunity to try teaching. And having tried it, I can now safely say that I like it. It’s also a great chance to meet people from all walks of life. It gets me out of my bubble.

I can’t remember when I was first paired up with Amber at CodeBar. It must have been sometime last year. I do remember that she had lots of great questions—at some point I found myself explaining how hexadecimal colours work.

I was impressed with Amber’s eagerness to learn. I also liked that she was making her own website. I told her about Homebrew Website Club and she started coming along to that (along with other CodeBar people like Cassie and Alice).

I’ve mentioned to multiple CodeBar students that there’s pretty much an open-door policy at Clearleft when it comes to shadowing: feel free to come along and sit with a front-end developer while they’re working on client projects. A few people have taken up the offer and enjoyed observing myself or Charlotte at work. Amber was one of those people. Again, I was very impressed with her drive. She’s got a full-time job (with sometimes-crazy hours) but she’s so determined to get into the world of web design and development that she’s willing to spend her free time visiting Clearleft to soak up the atmosphere of a design studio.

We’ve decided to turn this into something more structured. Amber and I will get together for a couple of hours once a week. She’s given me a list of some of the areas she wants to explore, and I think it’s a fine-looking list:

  • I want to gather base, structural knowledge about the web and all related aspects. Things seem to float around in a big cloud at the moment.
  • I want to adhere to best practices.
  • I want to learn more about what direction I want to go in, find a niche.
  • I’d love to opportunity to chat with the brilliant people who work at Clearleft and gain a broad range of knowledge from them.

My plan right now is to take a two-track approach: one track about the theory, and another track about the practicalities. The practicalities will be HTML, CSS, JavaScript, and related technologies. The theory will be about understanding the history of the web and its strengths and weaknesses as a medium. And I want to make sure there’s plenty of UX, research, information architecture and content strategy covered too.

Seeing as we’ll only have a couple of hours every week, this won’t be quite like the masterclass I just finished up in Porto. Instead I imagine I’ll be laying some groundwork and then pointing to topics to research. I guess it’s a kind of homework. For example, after we talked today, I set Amber this little bit of research for the next time we meet: “What is the difference between the internet and the World Wide Web?”

I’m excited to see where this will lead. I find Amber’s drive and enthusiasm very inspiring. I also feel a certain weight of responsibility—I don’t want to enter into this lightly.

I’m not really sure what to call this though. Is it mentorship? Or is it coaching? Or training? All of the above?

Whatever it is, I’m looking forward to documenting the journey. Amber will be writing about it too. She is already demonstrating a way with words.
