SKILL.md824 B

Overview

This skill architects a scalable design token propagation strategy for React apps using Context plus CSS-in-JS and CSS variables. It focuses on clear token layering (primitive vs component), runtime theme switching, and minimizing re-renders during global theme updates. The goal is a predictable, type-safe token system suitable for single apps and micro-frontends.

How this skill works

The skill defines a token schema and separates primitive tokens (colors, spacing, type) from component-level tokens derived from them. A ThemeProvider exposes tokens via React Context and also writes CSS variables to a top-level element so CSS-in-JS and plain styles can consume them. It includes runtime theme switching that updates Context values and CSS variables with minimal React re-renders, plus tools to benchmark rendering cost.

When to use it

Building a component library that must support multiple themes at runtime
Needing consistent tokens across React components and legacy CSS
Sharing design tokens between micro-frontends without full framework coupling
Optimizing theme switches to avoid unnecessary React re-renders
Enforcing a single source of truth for visual styles across apps

Best practices

Keep primitive tokens minimal and explicit (colors, spacing, type) and derive component tokens from them
Use a typed token schema (TypeScript interfaces) to ensure deep type-safety across nested token shapes
Write CSS variables for the primitives at root so both CSS-in-JS and classic styles read the same values
Batch Context updates and limit subscribed components to reduce re-render surface during theme changes
Measure runtime CSS generation cost and prefer precomputed variants when switching themes frequently

Example use cases

A multi-tenant SaaS that offers branded themes per customer and needs instant clientside switching
A design system that must be consumed by React apps and legacy pages simultaneously
A micro-frontend architecture where each sub-app reads the same token set via CSS variables
Performance audits where theme switch render time must be benchmarked and optimized

FAQ

Yes. The approach writes CSS variables to a root element so plain CSS or preprocessor outputs read the same tokens.

How do you avoid excessive re-renders on theme switch?

Limit Context consumers, memoize derived tokens, and update CSS variables directly for style-only changes to avoid React tree updates.
