To maintain UI consistency across React and Next.js projects, standardize design tokens, components, and global styles in a central design system. This ensures developers reuse existing assets while respecting defined style rules and token definitions.

Design tokens in a frontend design system are centralized variables that store visual design attributes like colors and spacing. They work by being referenced throughout UI components, enforcing global style consistency and preventing hardcoded values in your codebase.

Standardize UI components and document their usage by maintaining a central design system that specifies the location and implementation details for UI, layout, and domain components. This guides developers to correctly reuse existing assets across web applications.

While the design system approach is especially optimized for React and Next.js projects to ensure UI consistency, the core principles of standardizing tokens, components, and global styles can conceptually apply to other web application frameworks that support similar token definitions.

The best way to apply design tokens and existing components during UI development is to follow a workflow that prioritizes reusing existing assets first. Always reference the design system documentation to apply defined tokens and maintain consistent styling.

Your UI development lacks consistency without a centralized design system because design rules, token definitions, and component styles become scattered. A centralized system ensures these elements are documented and uniformly enforced across the entire codebase.
