Restyle is a type-enforced system for building UI components in React Native with TypeScript.
The library solves the problem of maintaining consistency across a themed UI by anchoring component styling to a design system's foundational values—colors, spacing, and other constants. Rather than allowing arbitrary style values throughout an application, Restyle enforces that components draw from a predefined theme, with TypeScript providing compile-time safety. The system acknowledges that exceptions will occur and permits style overrides when necessary, but keeps developers most productive when one-off values remain minimal.
Teams building React Native applications with a design system should consider Restyle if they want type safety and consistency enforced at the component level. It is designed as a library for building UI libraries rather than for direct application use, making it most suitable for organizations creating reusable component systems. The tool is inspired by styled-system, sharing a similar philosophy of constraint-based styling.
The project maintains active documentation with a dedicated site and includes a fixture application demonstrating usage patterns. A migration guide exists for teams moving to a major version update. The repository includes contribution guidelines and a code of conduct, indicating structured community engagement.
