FAQPage Schema
How do I generate a Next.js demo app from a specification?

You can generate a Next.js demo app by defining detailed screen types, components, and sample data domains in a CLAUDE.md specification file. The demo-builder skill reads this spec to automatically create App Router screens, mock data, and API routes without manual boilerplate code.

Can I customize the UI theme and screen types for generated Next.js prototypes?

Yes, you can customize the UI theme and adapt different screen types like dashboards, tables, or chats for your Next.js prototypes. The generation process applies your specified theme colors and builds corresponding components based on the defined screen types.

What do I need to prepare before generating a Next.js demo application?

You need to prepare a CLAUDE.md specification file detailing your proposed features, screen types, and sample data domains. This specification serves as the input for the zero-code app generation process to build the functional demo.

Does the generated demo app include mock data and API routes?

Yes, the generated demo app includes mock data and API routes. It creates these elements based on the sample data domains defined in your CLAUDE.md specification to ensure the prototype is fully functional for client proposals.

When should I use automated code generation for frontend prototyping?

You should use automated code generation for frontend prototyping when you need to quickly produce a functional demo app for a client proposal. It eliminates manual front-end development for prototypes, allowing you to showcase proposed features and user flows rapidly.
