The Technical Side of Design Systems by Brad Frost

Day two of An Event Apart San Francisco is finishing with a talk from Brad on design systems (so hot right now!):

You can have a killer style guide website, a great-looking Sketch library, and robust documentation, but if your design system isn’t actually powering real software products, all that effort is for naught. At the heart of a successful design system is a collection of sturdy, robust front-end components that powers other applications’ user interfaces. In this talk, Brad will cover all that’s involved in establishing a technical architecture for your design system. He’ll discuss front-end workshop environments, CSS architecture, implementing design tokens, popular libraries like React and Vue.js, deploying design systems, managing updates, and more. You’ll come away knowing how to establish a rock-solid technical foundation for your design system.

I will attempt to liveblog the Frostmeister…

“Design system” is an unfortunate name …like “athlete’s foot.” You say it to someone and they think they know what you mean, but nothing could be further from the truth.

As Mina said:

A design system is a set of rules enforced by culture, process and tooling that govern how your organization creates products.

A design system the story of how an organisation gets things done.

When Brad talks to companies, he asks “Have you got a design system?” They invariably say they do …and then point to a Sketch library. When the focus goes on the design side of the process, the production side can suffer. There’s a gap between the comp and the live site. The heart and soul of a design system is a code library of reusable UI components.

Brad’s going to talk through the life cycle of a project.

Sell

He begins with selling in a design system. That can start with an interface inventory. This surfaces visual differences. But even if you have, say, buttons that look the same, the underlying code might not be consistent. Each one of those buttons represents time and effort. A design system gives you a number of technical benefits:

  • Reduce technical debt—less frontend spaghetti code.
  • Faster production—less time coding common UI components and more time building real features.
  • Higher-quality production—bake in and enforce best practices.
  • Reduce QA efforts—centralise some QA tasks.
  • Potentially adopt new technologies faster—a design system can help make additional frameworks more managable.
  • Useful reference—an essential resource hub for development best practices.
  • Future-friendly foundation—modify, extend, and improve over time.

Once you’ve explained the benefits, it’s time to kick off.

Kick off

Brad asks “What’s yer tech stack?” There are often a lot of tech stacks. And you know what? Users don’t care. What they see is one brand. That’s the promise of a design system: a unified interface.

How do you make a design system deal with all the different tech stacks? You don’t (at least, not yet). Start with a high priority project. Use that as a pilot project for the design system. Dan talks about these projects as being like television pilots that could blossom into a full season.

Plan

Where to build the design system? The tech stack under the surface is often an order of magnitude greater than the UI code—think of node modules, for example. That’s why Brad advocates locking off that area and focusing on what he calls a frontend workshop environment. Think of the components as interactive comps. There are many tools for this frontend workshop environment: Pattern Lab, Storybook, Fractal, Basalt.

How are you going to code this? Brad gets frontend teams in a room together and they fight. Have you noticed that developers have opinions about things? Brad asks questions. What are your design principles? Do you use a CSS methodology? What tools do you use? Spaces or tabs? Then Brad gets them to create one component using the answers to those questions.

Guidelines are great but you need to enforce them. There are lots of tools to automate coding style.

Then there’s CSS architecture. Apparently we write our styles in React now. Do you really want to tie your CSS to one environment like that?

You know what’s really nice? A good ol’ sturdy cacheable CSS file. It can come in like a fairy applying all the right styles regardless of tech stack.

Design and build

Brad likes to break things down using his atomic design vocabulary. He echoes what Mina said earlier:

Embrace the snowflakes.

The idea of a design system is not to build 100% of your UI entirely from components in the code library. The majority, sure. But it’s unrealistic to expect everything to come from the design system.

When Brad puts pages together, he pulls in components from the code library but he also pulls in one-off snowflake components where needed.

The design system informs our product design. Our product design informs the design system.

—Jina

Brad has seen graveyards of design systems. But if you make a virtuous circle between the live code and the design system, the design system has a much better chance of not just surviving, but thriving.

So you go through those pilot projects, each one feeding more and more into the design system. Lather, rinse, repeat. The first one will be time consuming, but each subsequent project gets quicker and quicker as you start to get the return on investment. Velocity increases over time.

It’s like tools for a home improvement project. The first thing you do is look at your current toolkit. If you don’t have the tool you need, you invest in buying that new tool. Now that tool is part of your toolkit. Next time you need that tool, you don’t have to go out and buy one. Your toolkit grows over time.

The design system code must be intuitive for developers using it. This gets into the whole world of API design. It’s really important to get this right—naming things consistently and having predictable behaviour.

Mina talked about loose vs. strict design systems. Open vs. locked down. Make your components composable so they can adapt to future requirements.

You can bake best practices into your design system. You can make accessibility a requirement in the code.

Launch

What does it mean to “launch” a design system?

A design system isn’t a project with an end, it’s the origin story of a living and evolving product that’ll serve other products.

—Nathan Curtis

There’s a spectrum of integration—how integrated the design system is with the final output. The levels go from:

  1. Least integrated: static.
  2. Front-end reference code.
  3. Most integrated: consumable compents.

Chris Coyier in The Great Divide talked about how wide the spectrum of front-end development is. Brad, for example, is very much at the front of the front end. Consumable UI components can create a bridge between the back of the front end and the front of the front end.

Consumable UI components need to be bundled, packaged, and published.

Maintain

Now we’ve entered a new mental space. We’ve gone from “Let’s build a website” to “Let’s maintain a product which other products use as a dependency.” You need to start thinking about things like semantic versioning. A version number is a promise.

A 1.0.0 designation comes with commitment. Freewheeling days of unstable early foundations are behind you.

—Nathan Curtis

What do you do when a new tech stack comes along? How does your design system serve the new hotness. It gets worse: you get products that aren’t even web based—iOS, Android, etc.

That’s where design tokens come in. You can define your design language in a platform-agnostic way.

Summary

This is hard.

  • Your design system must live in the technologies your products use.
  • Look at your product roadmaps for design system pilot project opportunities.
  • Establish code conventions and use tooling and process to enforce them.
  • Build your design system and pilot project UI screens in a frontend workshop environment.
  • Bake best practices into reusable components & make them as rigid or flexible as you need them to be.
  • Use semantic versioning to manage ongoing design system product work.
  • Use design tokens to feed common design properties into different platforms.

You won’t do it all at once. That’s okay. Baby steps.

Dark mode

I had a very productive time at Indie Web Camp Amsterdam. The format really lends itself to getting the most of a weekend—one day of discussions followed by one day of hands-on making and doing. You should definitely come along to Indie Web Camp Brighton on October 19th and 20th to experience it for yourself.

By the end of the “doing” day, I had something fun to demo—a dark mode for my website.

Y’know, when I first heard about Apple adding dark mode to their OS—and also to CSS—I thought, “Oh, great, Apple are making shit up again!” But then I realised that, like user style sheets, this is one more reminder to designers and developers that they don’t get the last word—users do.

Applying the dark mode styles is pretty straightforward in theory. You put the styles inside this media query:

@media (prefers-color-scheme: dark) {
...
}

Rather than over-riding every instance of a colour in my style sheet, I decided I’d do a little bit of refactoring first and switch to using CSS custom properties (or variables, if you will).

:root {
  --background-color: #fff;
  --text-color: #333;
  --link-color: #b52;
}
body {
  background-color: var(--background-color);
  color: var(--text-color);
}
a {
  color: var(--link-color);
}

Then I can over-ride the custom properties without having to touch the already-declared styles:

@media (prefers-color-scheme: dark) {
  :root {
    --background-color: #111416
    --text-color: #ccc;
    --link-color: #f96;
  }
}

All in all, I have about a dozen custom properties for colours—variations for text, backgrounds, and interface elements like links and buttons.

By using custom properties and the prefers-color-scheme media query, I was 90% of the way there. But the devil is in the details.

I have SVGs of sparklines on my homepage. The SVG has a hard-coded colour value in the stroke attribute of the path element that draws the sparkline. Fortunately, this can be over-ridden in the style sheet:

svg.activity-sparkline path {
  stroke: var(--text-color);
}

The real challenge came with the images I use in the headers of my pages. They’re JPEGs with white corners on one side and white gradients on the other.

header images

I could make them PNGs to get transparency, but the file size would shoot up—they’re photographic images (with a little bit of scan-line treatment) so JPEGs (or WEBPs) are the better format. Then I realised I could use CSS to recreate the two effects:

  1. For the cut-out triangle in the top corner, there’s clip-path.
  2. For the gradient, there’s …gradients!
background-image: linear-gradient(
  to right,
  transparent 50%,
  var(—background-color) 100%
);

Oh, and I noticed that when I applied the clip-path for the corners, it had no effect in Safari. It turns out that after half a decade of support, it still only exists with -webkit prefix. That’s just ridiculous. At this point we should be burning vendor prefixes with fire. I can’t believe that Apple still ships standardised CSS properties that only work with a prefix.

In order to apply the CSS clip-path and gradient, I needed to save out the images again, this time without the effects baked in. I found the original Photoshop file I used to export the images. But I don’t have a copy of Photoshop any more. I haven’t had a copy of Photoshop since Adobe switched to their Mafia model of pricing. A quick bit of searching turned up Photopea, which is pretty much an entire recreation of Photoshop in the browser. I was able to open my old PSD file and re-export my images.

Let’s just take a moment here to pause and reflect on the fact that we can now use CSS to create all sorts of effects that previously required a graphic design tool like Photoshop. I could probably do those raster scan lines with CSS if I were smart enough.

dark mode

This is what I demo’d at the end of Indie Web Camp Amsterdam, and I was pleased with the results. But fate had an extra bit of good timing in store for me.

The very next day at the View Source conference, Melanie Richards gave a fantastic talk called The Tailored Web: Effectively Honoring Visual Preferences (seriously, conference organisers, you want this talk on your line-up). It was packed with great insights and advice on impementing dark mode, like this little gem for adjusting images:

@media (prefers-color-scheme: dark) {
  img {
    filter: brightness(.8) contrast(1.2);
  }
}

Melanie also pointed out that you can indicate the presence of dark mode styles to browsers, although the mechanism is yet to shake out. You can do it in CSS:

:root {
  color-scheme: light dark;
}

But you can also do it in HTML:

That allows browsers to swap out replaced content; interface elements like form fields and dropdowns.

Oh, and one other addition I added after the fact was swapping out map imagery by using the picture element to point to darker map tiles:

<picture>
<source media="(prefers-color-scheme: dark)" srcset="https://api.mapbox.com/styles/v1/mapbox/dark-v10/static...">
<img src="https://api.mapbox.com/styles/v1/mapbox/outdoors-v10/static..." alt="map">
</picture>

So now I’ve got a dark mode for my website. Admittedly, it’s for just one of the eight style sheets. I’ve decided that, while I’ll update my default styles at every opportunity, I’m going to preservethe other skins as they are, like the historical museum pieces they are.

If you’re on the latest version of iOS, go ahead and toggle the light and dark options in your system preferences to flip between this site’s colour schemes.

Summer of Apollo

It’s July, 2019. You know what that means? The 50th anniversary of the Apollo 11 mission is this month.

I’ve already got serious moon fever, and if you’d like to join me, I have some recommendations…

Watch the Apollo 11 documentary in a cinema. The 70mm footage is stunning, the sound design is immersive, the music is superb, and there’s some neat data visualisation too. Watching a preview screening in the Duke of York’s last week was pure joy from start to finish.

Listen to 13 Minutes To The Moon, the terrific ongoing BBC podcast by Kevin Fong. It’s got all my favourite titans of NASA: Michael Collins, Margaret Hamilton, and Charlie Duke, amongst others. And it’s got music by Hans Zimmer.

Experience the website Apollo 11 In Real Time on the biggest monitor you can. It’s absolutely wonderful! From July 16th, you can experience the mission timeshifted by exactly 50 years, but if you don’t want to wait, you can dive in right now. It genuinely feels like being in Mission Control!

Audio I listened to in 2018

I wrapped up last year with a list of some of the best audio I listened to in 2017. This year I huffduffed about 260 pieces of audio, so I could do a similar end-of-year list for 2018. But I thought I’d do something a little different this time.

It seems like podcasting is going from strength to strength with each passing year. Some friends of mine started new podcasts in 2018. Matt started Hobby Horse, where he talks to people about their tangential obsessions. Meanwhile Khoi started Wireframe, a jolly good podcast about design.

Apart from the trend of everyone having their own podcast these days, there’s also been a trend for quite short and manageable “seasons” of podcasts. See, for example, Horizon Line by Atlas Obscura, which is just four episodes long. Given the cherry-picking nature of my usual audio consumption (the very reason I made Huffduffer in the first place), this trend suits me quite well. There have been a few podcast runs in 2018 that I can recommend in their entirety.

The Secret History Of The Future is a collaboration between Seth Stevenson and Tom Standage, one of my favourite non-fiction authors. They look at modern technology stories through the lens of the past, much like Standage has done in books like The Victorian Internet. There are annoying sponsor blurbs to skip past, but apart from that, it’s a top-notch podcast.

I discovered Settling The Score this year. It’s a podcast all about film scores. The two hosts have spent the year counting down the top 25 scores in the American Film Institute’s list of (supposedly) greatest scores in American cinema history. It’s a pleasure to listen to them take a deep dive into each film and its score, analysing what works and what doesn’t. It will also make you want to rewatch the movie in question.

By far my favourite podcast listening experience this year was with Stephen Fry’s Great Leap Years. It’s just six episodes long, but it manages to tell the sweep of human history and technology in an entertaining and fascinating way. I’ll admit I’m biased because it dwells on many of my hobby horses: the printing press, the telegraph, Claude Shannon and information theory. There are no annoying sponsorship interruptions, and best of all, you’ve got the wonderful voice of Stephen Fry in your earholes the whole time. Highly recommended!

So there you have it: three podcasts from 2018 that are worth subscribing to in their entirety:
