Design Systems for One-Person Projects: What to Keep, What to Skip
The W3C Design Tokens Community Group recently released the first stable version of its vendor-agnostic specification for representing design decisions. With support for sharing design tokens across tools and platforms, this standard provides a practical foundation for even a single designer to maintain a consistent visual language across a website or app.
What a Design System Really Is (In One Sentence and Beyond)
At its core, a design system is a shared set of design decisions made executable. These include design tokens, reusable components, and documented rules that help teams ship products with coherent visual design and behaviors, without re-deciding the same questions. As one design glossary puts it, a design system is "a shared set of design decisions made executable" — a coordinated collection of reusable components, tokens, and documented rules.
The smallest unit of a design system is the design token: a named, machine-readable design decision (such as a color value, spacing, or font size) that can be consumed by both tools and code. That might sound complex for a one-person project, but if you think of tokens as variables capturing single design decisions like a color, spacing, or font size, then it's clear their core benefit is consistency.
A design system is about more than just a button or card component: it includes design tokens and guidelines for how and when to use them. But for a small project, the extra structure doesn't have to be daunting. We can distill out the minimum "system" that actually provides value.
Design Tokens: The Smallest Useful Piece
The W3C Design Tokens Community Group defines tokens as a technology for expressing design decisions in a platform-agnostic format. Tokens capture indivisible pieces of a design system like color, spacing, and typography, and represent the single source of truth for those design decisions throughout a product.
Here's how that works in practice:
- A design token is a named variable storing a platform-agnostic value, like a color or spacing. It might be called
color.blue.500orspacing.small. - Tokens can reference other tokens, creating a compositional hierarchy.
- The W3C JSON scheme includes a
$value(the actual value like a hex color or pixel value), a$type(such as color or dimension), and optionally a$description. - This setup lets designers work with meaningful names and values, which can be translated into any technology or platform as needed.
- For example, a component token like button.primary.background might point to the color.blue.500 primitive.
For a single maintainer, this structure is a lightweight way to centralize design decisions without a lot of overhead. As the Salesforce Design System puts it, "Design tokens are the visual design atoms of the design system."
How the W3C Token Standard Helps Even Tiny Projects
The W3C's goal isn't just to enable large teams to share design data. Its updated JSON format allows any tool (design tools, build systems) to read the same structured token files. That means a small project can use design tokens now and easily switch tools in the future. It's future-proofing from the start.
Because tokens capture reusable design decisions— indefinites like color names, spacing scales, and component tokens for common elements like buttons or cards— they help maintain consistency even on a tiny site. A solo developer creating a landing page could quickly set up a small set of dot notation tokens for colors and spacing. Then that palette is available in code and design tools, without having to manually change values everywhere.
Components and Rules: The Rest of the System
Beyond tokens, a design system includes reusable components and guidelines for using them. Components aim to solve common UI problems in a consistent way, while rules explain when and how to use components, tokens, and other systems.
The distinction matters, because tokens are an investment of time and thought that pays off across more than a few static pages. Tokens build a shared taxonomy that attaches meaning to common design decisions, and provide a single source of truth to avoid hardcoded behaviors or style drift. When a small project outgrows its initial design, having design tokens in place reduces the work of stranding and rescaling.
A Minimal Token Setup for a Small Site
So what does a "minimum viable design system" look like, even for a one-person site? In this case, think in terms of tiered tokens rather than a massive component library:
- Primitive tokens like colors, spacing, typography. Think of your color palette, and the spacing and font size scales you anticipate using repeatedly.
- Semantic tokens to group related primitives.
- Component-scoped tokens for any design decisions specific to recurring interface elements like a call-to-action button or footer.
- Example: color.blue.500: #0073e6, spacing.xs: 4px
- Example: color.background: color.blue.500, size.button: size.medium
- Example: button.primary.background: color.background, button.primary.padding: spacing.xs
Again, the key is to use these tokens as your single source of truth for design decisions. Because tokens are platform-agnostic, a designer can sketch concepts and mockups in a tool that reads their token values, and then share the same values with the build. As simple as that, a small design system creates consistency.
When a Full Design System Is Overkill—and When It Isn’t
So if it's this easy to set up a minimal, token-only system, does that mean every project should start with a full system? No. But starting with tokens is a best practice that pays off in consistency and longevity, even at scale.
By using design tokens, a solo developer gains all of these benefits of a full system — reuse, future-proofing, and design/execution alignment — without the time and effort of a full design system. And because the W3C is standardizing design tokens, it's a future-proof starting point. As a designer or developer scales, it's easy to expand with more components and documentation.
