Duet Design System December 2019 Update

You’re reading the fourth Duet Design System monthly update. In this update we’ll share statistics and feedback we’ve received regarding Duet’s public launch.

Last month marked a major milestone for us as we launched Duet publicly. A little under a month has gone by, and we’ve seen more than 12.000 unique visitors from all over the globe.

Most of the visitors are coming from United States, Finland, and the UK, but in total we’re seeing traffic from 72 different countries. A simplified overview of the past three+ weeks’ statistics looks like this:

  • 200.000 page views
  • 12.000 unique visitors
  • 72 countries represented
  • 52.000 goal completions
  • 100+ websites and blogs sharing Duet
  • 1 million files served via our CDN

While a lot of the traffic has been coming from social media, Duet has also been shared on these websites, publications, and newsletters:

The conversation has been fairly active on Twitter too. I personally tweeted this on November 6th and it ended up being the single biggest source of traffic for our documentation (thanks to all the retweets, people):

Zach Leatherman, who created the tool called Eleventy that our documentation also uses, commented:

Similarly, Teppo Haste from our team shared Duet on LinkedIn which resulted in a bunch of new traffic and questions about the work we’ve done so far:



All in all, we’re really happy about the reception. This makes us want to push towards even higher quality content in the future for both our clients, and the design and development teams utilizing Duet.

Now is also a good time to say thanks to all our partners that have been a part of this journey so far: Kuudes, Dunning, Kruger & Associates, HiQ Finland, CGI, Tata Consultancy Services, and all in-house teams, a big thank you!

New this month

In this section we’ll highlight every month new features and progress from Duet Design System. This month’s highlights include:

Desktop application

Duet’s documentation is now available as a progressive web app with offline support. Using Chrome on Desktop and Android, or Safari on iOS lets you install Duet onto your device. Follow these instructions to get started.

Process for adding components

We’ve completely reworked our contributing guidelines and have included a new flow diagram that helps you determine whether a component belongs to the design system or should be kept application specific instead.

New layout tools

During the past month we’ve focused on improving Duet’s layout tools. We’ve introduced new components like Layout, Grid, Grid Item and Spacer. The responsive capabilities of most components have been improved as well.

Visual regression tests

Automated visual regression tests allow us to make sure that our components render as expected across different browsers after changes are made to the code. They also help us deliver higher quality releases with less bugs.

On the roadmap next

  • Getting more components ready for production usage is still our first priority at the moment. For an up-to-date list on progress and what’s under work, view component statuses.
  • Our next priority is to support designers and developers who start utilizing these new parts. If you have any questions, please view support page and reach out.
  • Finally, we’re also starting to focus more on contribution and adoption from different teams and plan for 2020.

Until 2020!
