The Fabric Design System: A library of user interface components to create finance apps

The Fabric Design System is a library of user interface components to create finance apps, like Centrifuge Pools. The system offers a shared language of semantic primitives and is available both in design and code, thus bridging the gap between specification and implementation, serving designers and developers alike.

Say you have a brilliant feature idea for the Centrifuge Pools app and you want to mock up its user interface. Or maybe you’d like to build an entirely new app on top of the Centrifuge protocol, and you need an exhaustive and carefully tuned system of components to go full boom…
Welcome the Fabric Design System. This post introduces what a design system is for, what Fabric is about, and gets you started with using it yourself.

What is a design system?

The Nielsen Norman Group offers a good definition. The used term scale applies both to the number of different apps, and the scope of one individual app.

A design system is a complete set of standards intended to manage design at scale using reusable components and patterns. Source

Why a design system?

For creation, a design system offers an unlimited range of expression within defined constraints. These constraints – the predefined parts – empower non-designers to quickly ideate and prototype solution ideas. The design system serves as frame to focus on solving design problems.

A design system built on a solid architecture allows standardization and reuse of solutions, so one does not end up with an app consisting of multiple custom solutions. A system of coherent parts allows for consistency and fast evolution; because of its modular nature, changing a style or a component takes effect in all instances.

What is Fabric?

The Fabric Design System is the set of parts that our Centrifuge Pools app is made with. These parts are common user interface elements, like buttons, cards, input elements, or tables, which have been carefully considered to be composed into one coherent app. Every component has its style built in – so you, as the design system user, don’t have to fuss with picking the right color, font, margin, and icon. The protocol’s brand values – bold, visionary, trustworthy, reliable, inclusive, and collaborative – have materialized in the styles and components.

Think about the Fabric components as the basic ingredients and the app (e.g. Centrifuge Pools) as the finished solution integrating these components. For example, Centrifuge Pools has a specific detail header, which uses the Fabric components object thumbnail, heading, button, and tab navigation. This separation is because Fabric aims to be a universal system rather than being limited to just one application.

How can I use Fabric?

The best way to use Fabric is by trying it out.
To create a new design, use the Figma library.
This primer video shows how.
To start building directly in code, head over to the Apps repo, and browse the components on Storybook.

These are the steps on how to use the Figma library:

  1. Duplicate the Fabric design system on Figma Community to copy it to your Drafts folder
  2. Browse the component examples to get an overview of the configuration capabilities
  3. Copy the examples to create your own compositions

How can I apply my own brand?

In a similar fashion to how components are decoupled from a single-app use case, the theme is abstracted from a particular brand identity. The default brand is the Centrifuge Brand.

The theme is based on two accent colors: primary, and secondary. To adapt Fabric to your own brand, define the primary and secondary colors, and then assign them to the semantic color styles, like backgroundButtonPrimary, or borderFocus.

In addition, the primary accent color uses a scale of 10 shades which are used as highlight and interactive color, and charts.

Now what?

Centrifuge Pools is the first app using Fabric, and we’re curious to see it being adopted by the community. After all, it’s meant to be a useful workhorse – go ahead and try it! And let us know your thoughts, feedback, and suggestions.
