Article: From Reusable to Regeneratable: Rethinking the Shared UI Component Library
Regeneration has changed reuse economics. A model pointed at a solid design system can produce most standard UI on demand, so paying to keep a canonical component package alive is much harder to justify than it used to be. Keep the design system, tokens, guidelines and tests central. They are what actually buy you consistency. By Daniel Curtis
For most of the past ten years, the prevailing wisdom inside growing engineering organizations was to create a shared UI component library. Bundling buttons, modals, grids, and form controls into one versioned package was thought to provide consistency, accessibility, and speed. This approach seemed inherent to the industry's DNA, with reusability equated to efficiency.
However, the relevance of this shared library model has evolved since 2026. Advances in coding agents that can swiftly produce styled, accessible components have altered the calculus. While the initial building of a shared library once took considerable time, the true cost arises from maintaining and supporting the library years later as various applications rely on it.
Centralizing the design system, tokens, guidelines, and tests now appears more critical than maintaining the shipped component code. Griffiths Waite has firsthand experience with this shift, having spent a decade constructing shared UI components in React and managing design systems for large enterprises. While shared libraries have benefits, maintaining them requires ongoing effort and attention, particularly when dependency management, versioning, and communication become increasingly complex.
Generative AI has further shifted the landscape, with AI-driven code generation making the initial implementation cost lower, thus prompting a reevaluation of the role of shared libraries.
