React Component Library with Design Tokens: A Practical Architecture

A React component library with design tokens should do more than centralize colors and spacing. It should give your team a repeatable architecture for component APIs, usage guidance, and theming decisions that can survive rapid iteration and AI-assisted development.

Fragments combines these concerns into one workflow.

## What the Architecture Needs to Support

A practical architecture should support:

- component-level docs with examples and props - token-driven styling and theming - a build step that compiles metadata for tooling - a path for AI to query the real component system

Fragments covers those layers with the [components docs](/components), [CLI](/governance/cli), and [MCP Tools](/governance/mcp).

## How Fragments Connects Components and Tokens

Fragments uses seed-based theming to derive design tokens and applies them across the component library. That means visual updates propagate consistently instead of relying on one-off overrides.

Use [Getting Started](/components/install) to wire the library into your React app, then tune the token system through its seed values.

## FAQ

### Are design tokens enough to keep UI consistent?

No. Tokens solve visual consistency, but you also need component usage guidance and documented patterns.

### Why include AI tooling in the architecture?

Because AI is now part of many teams' implementation workflow. If it cannot query your real system, it will guess.

## CTA

Start with the [components docs](/components), then connect the [MCP Tools](/governance/mcp) once your team wants AI to build against the same system.
