This is terrific! Jeremy shows how you can implement a fairly straightforward service worker for performance gains, but then really kicks it up a notch with a recipe for turning a regular website into a speedy single page app without framework bloat.
One of the other arguments we hear in support of the SPA is the reduction in cost of cyber infrastructure. As if pushing that hosting burden onto the client (without their consent, for the most part, but that’s another topic) is somehow saving us on our cloud bills. But that’s ridiculous.
2010 was quite a year:
And exactly three weeks after Jeremy Keith’s HTML5 For Web Designers was first published, “Responsive Web Design” went live in A List Apart.
Nothing’s been quite the same since.
I remember being at that An Event Apart in Seattle where Ethan first unveiled the phrase and marvelling at how well everything just clicked into place, perfectly capturing the zeitgeist. I was in. 100%.
John’s article, A Dao Of Web Design, is twenty years old. If anything, it’s more relevant today than when it was written.
Here, John looks back on those twenty years, and forward to the next twenty…
- Write Chronologically, Not Spatially
- Write Left to Right, Top to Bottom
- Don’t Use Colors and Icons Alone
- Describe the Action, Not the Behavior
Aaron outlines some sensible strategies for serving up images, including using the Cache API from your service worker script.
This chimes nicely with my recent post on third-party scripts. Here, Jeremy treats third-party JavaScript at technical debt and outlines some solutions to staying on top of it.
Convenience always has a price, and the web is wracked by our collective preference for it. JavaScript, in particular, is employed in a way that suggests a rapidly increasing tendency to outsource whatever it is that We (the first party) don’t want to do. At times, this is a necessary decision; it makes perfect financial and operational sense in many situations.
But make no mistake, third-party JavaScript is never cheap. It’s a devil’s bargain where vendors seduce you with solutions to your problem, yet conveniently fail to remind you that you have little to no control over the side effects that solution introduces.
On an individual and small collective basis, the IndieWeb already works. But does an IndieWeb approach scale to the general public? If it doesn’t scale yet, can we, who envision and design and build, create a new generation of tools that will help give birth to a flourishing, independent web? One that is as accessible to ordinary internet users as Twitter and Facebook and Instagram?
This is a fascinating insight into what it’s like to use the web if you’ve got vertigo (which is way more common than you might think):
Really, there are no words to describe just how bad a simple parallax effect, scrolljacking, or even
background-attachment: fixedwould make me feel. I would rather jump on one of those 20-G centrifuges astronauts use than look at a website with parallax scrolling.Every time I encountered it, I would put the bucket beside me to good use and be forced to lie in bed for hours as I felt the room spinning around me, and no meds could get me out of it. It was THAT bad.
As I pick apart yet another bundle not unlike a tangled ball of Christmas tree lights, it’s become clear that the web is drunk on JavaScript. We reach for it for almost everything, even when the occasion doesn’t call for it. Sometimes I wonder how vicious the hangover will be.
I love everything about this article and I can’t wait for part two.
What we tend to forget is that the environment websites and web apps occupy is one and the same. Both are subject to the same environmental pressures that the large gradient of networks and devices impose. Those constraints don’t suddenly vanish when we decide to call what we build “apps”, nor do our users’ phones gain magical new powers when we do so.
Needless to say, I endorse this message:
Whether you think of your site as an “app” or not, adding a service worker to it is perhaps one of the most responsible uses of JavaScript that exists today.
This is an excellent initiative by the Dutch Fronteers group to have professional web developers represented in W3C working groups. In this particular case, they’re funding Rachel for the CSS working group. This sets a great precedent—I really hope the W3C goes for it!
Yes! Yes! Yes!
Our efforts to measure and improve UX are packed with tragically ironic attempts to love our users: we try to find ways to improve our app experiences by bloating them with analytics, split testing, behavioral analysis, and Net Promoter Score popovers. We stack plugins on top of third-party libraries on top of frameworks in the name of making websites “better”—whether it’s something misguided, like adding a carousel to appease some executive’s burning desire to get everything “above the fold,” or something truly intended to help people, like a support chat overlay. Often the net result is a slower page load, a frustrating experience, and/or (usually “and”) a ton of extra code and assets transferred to the browser.
Even tools that are supposed to help measure performance in order to make improvements—like, say, Real User Monitoring—require you to add a script to your web pages …thereby increasing the file size and degrading performance! It’s ironic, in that Alanis Morissette sense of not understanding what irony is.
Stacking tools upon tools may solve our problems, but it’s creating a Jenga tower of problems for our users.
This is a great article about evaluating technology.
I love, love, love all the little details of HTML that Aaron offers up here. And I really like how he positions non-visual user-agents like searchbots, screen readers, and voice assisants as headless UIs.
HTML is a truly robust and expressive language that is often overlooked and undervalued, but it has the incredible potential to nurture conversations with our users without requiring a lot of effort on our part. Simply taking the time to code web pages well will enable our sites to speak to our customers like they speak to each other. Thinking about how our sites are experienced as headless interfaces now will set the stage for more natural interactions between the real world and the digital one.
This is a great description by Chris of the problems that webmentions aim to solve.
If you use Twitter, your friend Alice only uses Facebook, your friend Bob only uses his blog on WordPress, and your pal Chuck is over on Medium, it’s impossible for any one of you to @mention another. You’re all on different and competing platforms, none of which interoperate to send these mentions or notifications of them. The only way to communicate in this way is if you all join the same social media platforms, resulting in the average person being signed up to multiple services just to stay in touch with all their friends and acquaintances.
Given the issues of privacy and identity protection, different use cases, the burden of additional usernames and passwords, and the time involved, many people don’t want to do this. Possibly worst of all, your personal identity on the internet can end up fragmented like a Horcrux across multiple websites over which you have little, if any, control.
I know that Jeffrey and I sound like old men yelling at kids to get off the lawn when we bemoan the fetishisation of complex tools and build processes, but Jeffrey gets to the heart of it here: it’s about appropriateness.
As a designer who used to love creating web experiences in code, I am baffled and numbed by the growing preference for complexity over simplicity. Complexity is good for convincing people they could not possibly do your job. Simplicity is good for everything else.
And not to sound like a broken record, but once again I’m reminded of the rule of least power.
Oliver Williams makes the case—and shows the code—for delivering only HTML to old versions of Internet Explorer, sparing them from the kind of CSS and JavaScript that they can’t deal with it. Seems like a sensible approach to me (assuming you’re correctly building in a layered way so that your core content is delivered in markup).
Rather than transpiling and polyfilling and hoping for the best, we can deliver what the person came for, in the most resilient, performant, and robust form possible: unadulterated HTML. No company has the resources to actively test their site on every old version of every browser. Malfunctioning JavaScript can ruin a web experience and make a simple page unusable. Rather than leaving users to a mass of polyfills and potential JavaScript errors, we give them a basic but functional experience.
It really, really bothers me that wireframes have evolved from being a prioritisation tool into a layout tool (disempowering UI designers in the process), so I’m happy to see an alternative like this—somewhat like Dan Brown’s Page Description Diagrams.
Aaron gives a timely run-down of all the parts of a web experience that are out of our control. But don’t despair…
Recognizing all of the ways our carefully-crafted experiences can be rendered unusable can be more than a little disheartening. No one likes to spend their time thinking about failure. So don’t. Don’t focus on all of the bad things you can’t control. Focus on what you can control.
Start simply. Code defensively. User-test the heck out of it. Recognize the chaos. Embrace it. And build resilient web experiences that will work no matter what the internet throws at them.
The first chapter of my new book Going Offline has been published in A List Apart.
The first hit is free. If you like what you read here and you’re just dying to know how it ends, you can pre-order the book now (it’s shipping on April 24).
I love this analogy and I love this approach—starting with the simplest possible thing and building up from there. This article talks about taking that approach for UI design, but it’s pretty much the same thing I talk about for development in Resilient Web Design.
As Shakespeare once didn’t say, progressive enhancement by any other name would smell as sweet.
