Scaffolding UI And Pages

UI & Pages Scaffolding Specialist

Locate and read all artifacts in docs/legacy-audit/ directory.

Objective

Implement high-fidelity, modern React components using ShadCN and Tailwind, AND wire them together into fully functional Next.js pages (src/app/**/page.tsx) based on the requirements and Route Topology extracted from legacy Pug templates.

Instructions for the Scaffold Subagent

Copy this checklist and track your progress:

Task Progress:
- [ ] Step 1: Initialize ShadCN
- [ ] Step 2: Build Shared Layout Components (src/components/layout/)
- [ ] Step 3: Scaffold Domain Components (src/components/articles/, etc.)
- [ ] Step 4: Extract Route & Page Topology
- [ ] Step 5: Scaffold Pages (src/app/**/page.tsx)
- [ ] Step 6: Verification (Visual smoke-test)

1. Initialize Design System: Install the core ShadCN CLI using npx shadcn@latest init and configure the Tailwind theme (colors, fonts).
2. Build Shared Layouts: Create the Navbar, Footer, and MobileMenu.
   • Logic: Replicate the conditional logic (e.g., Auth-links) from the legacy metadata using Next.js getServerSession.
   • Modernize Features: Use premium ShadCN primitives (e.g., NavigationMenu, Avatar, Button, Card) instead of raw Bootstrap/CSS classes.
3. Component Scaffolding: Build specific logic-heavy components like CommentList and ArticleCard using the legacy field mapping.
4. Route & Page Topology Check: Go to the docs/legacy-audit/UI_Component_Inventory.md and explicitly extract the list of intended pages and URLs.
5. Page Scaffolding: For every single mapped route, create its routing wrapper in src/app/[path]/page.tsx (e.g. /articles needs src/app/articles/page.tsx). Hook up all business logic, server actions, UX intent, and data fetching components required.
6. Verification (Visual smoke-test): Verify that the UI is visually appealing and functional.

Output Result: Ensure all components are exported from src/components/ and all pages are functionally implemented in src/app/.

Base UI & asChild Best Practices

If the design system uses @base-ui/react primitives (standard in ShadCN v4+), you MUST follow these patterns for asChild support:

1. Implicit Slot Pattern: Use the render prop on Base UI primitives to implement asChild.
2. Button Semantics: When a Button or MenuItem acts as a Link (via asChild), you MUST set nativeButton={false} on the primitive to suppress semantics warnings and avoid invalid nested interactive elements.
   • Example: <ButtonPrimitive nativeButton={false} render={(props) => <Link {...props} />}>
3. Prop Merging: Use React.cloneElement or direct Prop spreading into the render callback to ensure ref, className, and event handlers are correctly merged onto the child.
