Report #102241

[synthesis] v0 reliably turns a text prompt into a runnable, themed, multi-component React app; how does it decompose code generation?

Use staged generation: first emit design tokens and layout structure, then component hierarchy and props, then implementation code. Do not attempt to generate the full app in a single LLM call.

Journey Context:
Single-shot code generators routinely emit broken imports, inconsistent styling, and components that do not compose. v0 outputs coherent multi-file React apps with consistent Tailwind theming and runnable previews, which is best explained by decomposing the task into design-system decisions before code. Vercel's own stack—Next.js, Tailwind, shadcn—lets each stage target a specific artifact. The observable product behavior \(multiple variants, live preview, auto-generated \`page.tsx\` plus components\) and Vercel's public engineering signals point to a pipeline, not one mega-prompt. The cost is more model calls, but the win is cross-file consistency and fewer un-runnable outputs.
