Add Page

Reference: apps/web/src/app/(dashboard)/projects/page.tsx

'use client';

import { trpc } from '@x4/shared/api-client';
import { Button } from '@/components/ui/button';
import { Card, CardContent, CardHeader, CardTitle } from '@/components/ui/card';

export default function MyPage() {
  const { data, isLoading, error } = trpc.routerName.list.useQuery({
    limit: 20,
    offset: 0,
  });

  if (isLoading) {
    return <div className="flex items-center justify-center p-8">Loading...</div>;
  }

  if (error) {
    return <div className="text-destructive p-8">Error: {error.message}</div>;
  }

  return (
    <div className="container mx-auto py-8">
      <div className="flex items-center justify-between mb-6">
        <h1 className="text-3xl font-bold">Page Title</h1>
        <Button>Action</Button>
      </div>

      <div className="grid gap-4 md:grid-cols-2 lg:grid-cols-3">
        {data?.items.map((item) => (
          <Card key={item.id}>
            <CardHeader>
              <CardTitle>{item.name}</CardTitle>
            </CardHeader>
            <CardContent>
              <p className="text-muted-foreground">{item.description}</p>
            </CardContent>
          </Card>
        ))}
      </div>
    </div>
  );
}

Server Page Template (no client state needed)

// No 'use client' directive

export default async function MyPage() {
  // Server-side data fetching if needed
  return (
    <div className="container mx-auto py-8">
      <h1 className="text-3xl font-bold">Page Title</h1>
      {/* Static or server-rendered content */}
    </div>
  );
}

Dynamic Route Page

'use client';

import { useParams } from 'next/navigation';
import { trpc } from '@x4/shared/api-client';

export default function DetailPage() {
  const { id } = useParams<{ id: string }>();
  const { data, isLoading } = trpc.routerName.get.useQuery({ id });
  // ...
}

Layout (optional, for shared UI in a section)

export default function SectionLayout({ children }: { children: React.ReactNode }) {
  return (
    <div className="max-w-4xl mx-auto">
      <nav>{/* Section navigation */}</nav>
      {children}
    </div>
  );
}

Conventions

• Imports: @x4/shared/* for cross-package, @/* for intra-workspace
• Styling: Tailwind v4 classes only — no CSS modules
• Components: shadcn/ui from @/components/ui/
• Data: tRPC hooks from @x4/shared/api-client
• File naming: kebab-case directories, page.tsx is the convention

Workflow

1. Determine route group ((auth) or (dashboard))
2. Create directory structure: apps/web/src/app/{group}/{path}/
3. Create page.tsx with appropriate template
4. Optionally create layout.tsx if the section needs shared UI
5. Verify the page renders: bun turbo dev and visit the URL
6. Run bun turbo type-check to verify
