FAQPage Schema
How do I preview live web components on a canvas instead of static shapes?

To preview live web components on a canvas, you can use a Vite dev server to render and iterate on interactive UI elements directly. This approach embeds components via iframes, offering a dynamic alternative to static shapes.

How do I prototype and compare multiple UI design variants side-by-side?

To prototype and compare UI design variants side-by-side, you can orchestrate subagents to explore different design options. This allows you to render multiple component variations simultaneously for direct visual comparison.

Does Vite work with canvas integration for frontend development and responsive previews?

Yes, Vite works with canvas integration by running a local dev server that supports isolated component previews via iframe embedding. This enables you to test responsive designs and iterate on web components directly on the canvas.

What is the best way to manage the lifecycle of UI components designed during prototyping?

The best way to manage the component lifecycle during prototyping is to integrate with mockup-extract and mockup-graduate skills. These tools handle component extraction and graduation from the canvas sandbox to production code.

Can I test responsive designs for React and HTML components without deploying a full application?

Yes, you can test responsive designs for React and HTML components without deploying by using an isolated canvas sandbox. A Vite dev server renders the live UI elements locally, allowing immediate iteration and preview via iframe embedding.
