[bug\_fix] Error: useSearchParams\(\) should be wrapped in a suspense boundary at page or Missing Suspense boundary with useSearchParams

Create a separate Client Component \(with "use client"\) that calls useSearchParams. Then import and wrap that component in a React Suspense boundary in the parent Server Component, providing a fallback UI \(e.g., loading spinner\). Do not call useSearchParams directly in the page.tsx Server Component. Root cause: useSearchParams reads from the URL \(window.location\) which is not available during server rendering or static generation. It requires browser APIs and must only execute on the client. Suspense creates a boundary that allows this client-only code to hydrate without blocking server rendering.

Journey Context:
Developer creates a search page in app/search/page.tsx. They add "use client" and import useSearchParams from next/navigation. They write const searchParams = useSearchParams\(\); const query = searchParams.get\('q'\);. During development, it works. They run npm run build for production and get the error: "useSearchParams\(\) should be wrapped in a suspense boundary at page". They try removing "use client" but then get "useSearchParams is not a function" because it's a server component. They search the error and find they need Suspense. They create a new component SearchParamsProvider.tsx with "use client" that uses the hook. In page.tsx \(server component\), they import SearchParamsProvider and wrap it in Loading search... \}>. The build succeeds. The fix works because useSearchParams requires browser APIs \(window.location.search\) which don't exist in Node.js during SSR. Suspense allows React to defer rendering this subtree until client-side JavaScript hydrates the component, showing the fallback initially then swapping in the component with access to URL params.
