Building an Enterprise‑Level Multi‑Brand, Multi‑Platform Design System at Ctrip

As mobile internet and smart devices proliferate, enterprises face diverse user demands across multiple brands and frameworks, requiring a comprehensive design system that ensures brand consistency and unified user experience across PCs, mobile, and other devices.

The multi‑brand, multi‑framework design system provides an efficient, reliable, and unified solution that enables design reuse and resource sharing, boosting quality while reducing costs.

Key challenges identified include brand inconsistency due to divergent team implementations, cross‑platform compatibility issues caused by varied technology stacks, and low component reusability leading to duplicated effort and maintenance overhead.

To address these, Ctrip introduced a modular design language with design tokens, flexible theme configuration, and a shared component library that allows rapid brand visual adjustments while maintaining overall consistency.

The cross‑platform solution, named xTaro, builds on the open‑source Taro framework and offers a unified API, component library, and build tools that enable a single codebase to run on H5, PC, mini‑programs, and native apps, improving code reuse and flexibility.

xTaro’s architecture consists of four layers—external modules, multi‑platform abstraction, platform extensions, and low‑level foundations—supporting seamless module degradation and platform‑specific adaptations.

Automation is achieved through Design‑to‑Code tools, visual design annotation systems, and theme configuration utilities, which convert design specifications directly into code and ensure consistent updates across the component library.

The final implementation combines a visual component library, a development SDK, and integrated design tools, providing designers and developers with a unified workflow that guarantees design‑development alignment, rapid theme switching, and high‑quality, reusable UI components.

In practice, the system enables flexible UI theme changes (e.g., dark mode, Ctrip vs. Trip branding) and supports future framework extensions, delivering a competitive, adaptable product experience.

Overall, the modular design language and component standards empower Ctrip to efficiently adapt to multi‑brand, multi‑framework environments, streamline development, and maintain a leading position in a fast‑changing market.
