Going Offline—the talk of the book

I gave a new talk at An Event Apart in Seattle yesterday morning. The talk was called Going Offline, which the eagle-eyed amongst you will recognise as the title of my most recent book, all about service workers.

I was quite nervous about this talk. It’s very different from my usual fare. Usually I have some big sweeping arc of history, and lots of pretentious ideas joined together into some kind of narrative arc. But this talk needed to be more straightforward and practical. I wasn’t sure how well I would manage that brief.

I knew from pretty early on that I was going to show—and explain—some code examples. Those were the parts I sweated over the most. I knew I’d be presenting to a mixed audience of designers, developers, and other web professionals. I couldn’t assume too much existing knowledge. At the same time, I didn’t want to teach anyone to such eggs.

In the end, there was an overarching meta-theme to talk, which was this: logic is more important than code. In other words, figuring out what you’re trying to accomplish (and describing it clearly) is more important than typing curly braces and semi-colons. Programming is an act of translation. Before you can translate something, you need to be able to articulate it clearly in your own language first. By emphasising that point, I hoped to make the code less overwhelming to people unfamilar with it.

I had tested the talk with some of my Clearleft colleagues, and they gave me great feedback. But I never know until I’ve actually given a talk in front of a real conference audience whether the talk is any good or not. Now that I’ve given the talk, and received more feedback, I think I can confidentally say that it’s pretty damn good.

My goal was to explain some fairly gnarly concepts—let’s face it: service workers are downright weird, and not the easiest thing to get your head around—and to leave the audience with two feelings:

  1. This is exciting, and
  2. This is something I can do today.

I deliberately left time for questions, bribing people with free copies of my book. I got some great questions, and I may incorporate some of them into future versions of this talk (conference organisers, if this sounds like the kind of talk you’d like at your event, please get in touch). Some of the points brought up in the questions were:

  • Is there some kind of wizard for creating a typical service worker script for any site? I didn’t have a direct answer to this, but I have attempted to make a minimal viable service worker that could be used for just about any site. Mostly I encouraged the questioner to roll their sleeves up and try writing a bespoke script. I also mentioned the Workbox library, but I gave my opinion that if you’re going to spend the time to learn the library, you may as well spend the time to learn the underlying language.
  • What are some state-of-the-art progressive web apps for offline user experiences? Ooh, this one kind of stumped me. I mean, the obvious poster children for progressive webs apps are things like Twitter, Instagram, and Pinterest. They’re all great but the offline experience is somewhat limited. To be honest, I think there’s more potential for great offline experiences by publishers. I especially love the pattern on personal sites like Una’s and Sara’s where people can choose to save articles offline to read later—like a bespoke Instapaper or Pocket. I’d love so see that pattern adopted by some big publications. I particularly like that gives so much more control directly to the end user. Instead of trying to guess what kind of offline experience they want, we give them the tools to craft their own.
  • Do caches get cleaned up automatically? Great question! And the answer is mostly no—although browsers do have their own heuristics about how much space you get to play with. There’s a whole chapter in my book about being a good citizen and cleaning up your caches, but I didn’t include that in the talk because it isn’t exactly exciting: “Hey everyone! Now we’re going to do some housekeeping—yay!”
  • Isn’t there potential for abuse here? This is related to the previous question, and it’s another great question to ask of any technology. In short, yes. Bad actors could use service workers to fill up caches uneccesarily. I’ve written about back door service workers too, although the real problem there is with iframes rather than service workers—iframes and cookies are technologies that are already being abused by bad actors, and we’re going to see more and more interventions by ethical browser makers (like Mozilla) to clamp down on those technologies …just as browsers had to clamp down on the abuse of pop-up windows in the early days of JavaScript. The cache API could become a tragedy of the commons. I liken the situation to regulation: we should self-regulate, but if we prove ourselves incapable of that, then outside regulation (by browsers) will be imposed upon us.
  • What kind of things are in the future for service workers? Excellent question! If you think about it, a service worker is kind of a conduit that gives you access to different APIs: the Cache API and the Fetch API being the main ones now. A service worker is like an airport and the APIs are like the airlines. There are other APIs that you can access through service workers. Notifications are available now on desktop and on Android, and they’ll be coming to iOS soon. Background Sync is another powerful API accessed through service workers that will get more and more browser support over time. The great thing is that you can start using these APIs today even if they aren’t universally supported. Then, over time, more and more of your users will benefit from those enhancements.

If you attended the talk and want to learn more about about service workers, there’s my book (obvs), but I’ve also written lots of blog posts about service workers and I’ve linked to lots of resources too.

Finally, here’s a list of links to all the books, sites, and articles I referenced in my talk…

Limiting JavaScript? - TimKadlec.com

Following on from that proposal for a browser feature that I linked to yesterday, Tim thinks through all the permutations and possibilities of user agents allowing users to throttle resources:

If a limit does get enforced (it’s important to remember this is still a big if right now), as long as it’s handled with care I can see it being an excellent thing for the web that prioritizes users, while still giving developers the ability to take control of the situation themselves.

Building links

In just over a week, I’ll be giving the opening talk at the New Adventures conference in Nottingham. I’ll be giving a workshop the day before too. There are still tickets available for both.

I have to admit, I’m kind of nervous about this talk. It’s been quite a while since the last New Adventures, but it’s always had quite the cachet. I think I went to most of them. It’s quite strange—and quite an honour—to shift gears from attendee to speaker.

The talk I’ll be giving is called Building. That might be a noun. That might be a verb. You decide:

Every new medium looks to what has come before for guidance. Web design has taken cues from centuries of typography and graphic design. Web development has borrowed metaphors and ideas from the world of architecture. Let’s take a tour of some of the most influential ideas from architecture that have crossed over into the web, from pattern languages to responsive design. Together we’ll uncover how to build resilient, performant, accessible and beautiful structures that work with the grain of the materials of the web.

This talk builds upon the talk I gave at last year’s An Event Apart called The Way Of The Web. It also reflects many of the ideas in Resilient Web Design. When I gave a run-through of the talk at Clearleft last week, Andy called it a “greatest hits.” For a while there, I was feeling guilty about retreading some ground I’ve covered in previous talks and writings. Then I realised it was pretty arrogant of me to think that anyone in the audience would be familiar with any of it.

Besides, I’ve got a whole new avenue of exploration in this talk. It’s about language and metaphor—how we talk about what we do on the web. I’ve just finished giving another run-through at the Clearleft studio and I’m feeling pretty good about it. That’s good, because I find that giving a talk in a small room to a handful of colleagues is way more stressful than giving a talk to hundreds of people at a conference.

Just as I put together links related to last year’s talk, I figured I’d provide some hyperlinks for anyone interested in the topics raised in this new talk…

The 15 Web Design Books of 2018 You Can’t Afford to Miss

How lovely! Going Offline is in very good company in this list, and Oliver has some nice words to say about it:

Starting with no assumption of JavaScript knowledge, Jeremy explains the latest strategies, the ins and outs of fetching and caching, how to enhance your website’s performance, and more.

Extremely beginner-friendly and approachable, it can be read in half a day and will help you get Service Workers up and running in no time.

But all I want for Christmas is for Shopify to stop enabling Breitbart.

I, Maintainer

Maintaining an open source project is a rollercoaster ride with high peaks and very low troughs.

Release frequency is down. Questions increasingly go unanswered. Issues remain in a triage, unresolved state. Uncertainty and frustration brew within the community room.

Brian’s experience with Pattern Lab very much mirrors Mark’s experience with Fractal. The pressure. The stress. But there’s also the community.

A maintainer must keep the needs of their project, their community, and their own needs in constant harmony.

This is hard!

as days pass by — Inside out

A very thoughtful post from Stuart, ostensibly about “view source”, but really about empowerment, choice, and respect.

I like that the web is made up of separate bits that you can see if you want to. You can understand how it works by piecing together the parts. It’s not meant to be a sealed unit, an appliance which does what the owner wants it to and restricts everything else. That’s what apps do. The web’s better than that.

GitHub Is Microsoft’s $7.5 Billion Undo Button - Bloomberg

Paul Ford explains version control in a way that is clear and straightforward, while also being wistful and poetic.

I had idle fantasies about what the world of technology would look like if, instead of files, we were all sharing repositories and managing our lives in git: book projects, code projects, side projects, article drafts, everything. It’s just so damned … safe. I come home, work on something, push the changes back to the master repository, and download it when I get to work. If I needed to collaborate with other people, nothing would need to change. I’d just give them access to my repositories (repos, for short). I imagined myself handing git repos to my kids. “These are yours now. Iteratively add features to them, as I taught you.”

Pi-hole®: A black hole for Internet advertisements

This looks like a terrific use of a Raspberry Pi—blocking adtech surveillance at the network level.

Wouldn’t it be great if the clichéd going-home-for-Christmas/Thanksgiving to fix the printer/wifi included setting up one of these?

There’s an article about Pi-hole in Business Week where the creators offer some advice for those who equate any kind of online advertising with ubiquitous surveillance:

For publishers struggling to survive even with maximum ad surveillance, the Pi-hole team recommends a renewed focus on subscriptions, affiliate links, and curated endorsements for products and services that might truly interest users, similar to the way podcast hosts may talk about how much they personally enjoy a sponsor’s products. There’s nothing wrong with pitching people stuff they might enjoy, the team says. It’s just the constant, ever-intensifying surveillance that needs to stop.
