963 markdown files reformatted with the repository's pinned prettier so pnpm format:check covers the folded tree like every other repo file. The formatter's embedded-language pass also normalized code fences (TS semicolons, closed HTML tags in examples, lowercased CSS hex colors, one renumbered list that skipped an index). Alphanumeric token deltas vs the fold commit were audited file-by-file; all are formatter-equivalent markup normalizations plus the four sanitized skills.

# Suspense Boundaries
|
|
|
|
Client hooks that cause CSR bailout without Suspense boundaries.
|
|
|
|
## useSearchParams
|
|
|
|
Always requires Suspense boundary in static routes. Without it, the entire page becomes client-side rendered.
|
|
|
|
```tsx
|
|
// Bad: Entire page becomes CSR
|
|
'use client';
|
|
|
|
import { useSearchParams } from 'next/navigation';
|
|
|
|
export default function SearchBar() {
|
|
const searchParams = useSearchParams();
|
|
return <div>Query: {searchParams.get('q')}</div>;
|
|
}
|
|
```
|
|
|
|
```tsx
|
|
// Good: Wrap in Suspense
|
|
import { Suspense } from 'react';
|
|
import SearchBar from './search-bar';
|
|
|
|
export default function Page() {
|
|
return (
|
|
<Suspense fallback={<div>Loading...</div>}>
|
|
<SearchBar />
|
|
</Suspense>
|
|
);
|
|
}
|
|
```
|
|
|
|
## usePathname
|
|
|
|
Requires Suspense boundary when route has dynamic parameters.
|
|
|
|
```tsx
|
|
// In dynamic route [slug]
|
|
// Bad: No Suspense
|
|
'use client';
|
|
import { usePathname } from 'next/navigation';
|
|
|
|
export function Breadcrumb() {
|
|
const pathname = usePathname();
|
|
return <nav>{pathname}</nav>;
|
|
}
|
|
```
|
|
|
|
```tsx
|
|
// Good: Wrap in Suspense
|
|
<Suspense fallback={<BreadcrumbSkeleton />}>
|
|
<Breadcrumb />
|
|
</Suspense>
|
|
```
|
|
|
|
If you use `generateStaticParams`, Suspense is optional.
