## Scaffolding

```bash
npx create-next-app@latest my-app --ts --tailwind --eslint --app --src-dir --import-alias "@/*"
cd my-app

# Runtime deps
pnpm add @prisma/client @prisma/adapter-neon @neondatabase/serverless \
  stripe @clerk/nextjs zustand next-themes

# Dev-only: the Prisma CLI is NOT a runtime dep
pnpm add -D prisma

pnpm dlx prisma init
pnpm dlx shadcn@latest init   # pick: New York style, CSS variables = yes
```

`reactCompiler` may require `babel-plugin-react-compiler` depending on the release — run `next build` once and follow any prompt.

```ts
// next.config.ts — Next.js 16
import type { NextConfig } from 'next';

const nextConfig: NextConfig = {
  // Cache Components: enables `'use cache'`, `cacheLife`, `cacheTag`,
  // and `'use cache: private'`. Replaces the old experimental.dynamicIO/useCache.
  cacheComponents: true,
  // React Compiler is top-level in 16 (no longer under experimental).
  reactCompiler: true,
};

export default nextConfig;
```
