mockup-extract

You can extract an existing UI component into a mockup sandbox by moving the real component with its dependencies, rewriting import paths, stubbing dependencies, and rendering it inside an isolated preview iframe for fast iteration.

Previewing a live UI component in isolation is achieved by extracting it into a mockup sandbox canvas, embedding the result in a preview iframe to enable side-by-side comparisons and rapid variant creation against new concepts.

Yes, you can redesign a live app component without rebuilding from scratch by pulling the existing component and its dependencies into an isolated mockup sandbox, ensuring accurate rendering and dependency stubbing for modifications.

Component extraction handles import path rewriting and dependency stubbing automatically during the process, ensuring the extracted UI component maintains accurate dependencies and renders correctly within the isolated mockup sandbox preview iframe.

You need a mockup sandbox for frontend UI component iteration when you want to redesign, create variants, or compare a live component against new concepts while ensuring accurate dependencies and rendering in a safe, isolated environment.

If an extracted UI component fails to render correctly in the mockup sandbox, it may be due to incomplete dependency stubbing or incorrect import path rewriting, which are enforced during the extraction process to ensure accurate isolated rendering.
