## What it does

The skill documents the pattern for the `useSearchParams` hook from `next/navigation`. Two things are required at once: the component carries the `'use client'` directive, and it sits inside a `<Suspense>` boundary. Skip the second one and the build breaks — this is a Next.js requirement, not a preference.

Inside are worked examples for three common jobs: a search page reading `q`, product filters driven by `category` and `sort`, and blog pagination through `page`. Both file layouts are covered, splitting the client component out or keeping everything in one file. There is also a section on updating params with `useRouter` and `URLSearchParams`, and on reading repeated keys with `getAll`.

Types get their own note: instead of `any`, lean on `useSearchParams` returning `ReadonlyURLSearchParams`, where `get` yields `string | null`. The skill grants the agent Read, Write, Edit, Glob, Grep and Bash, so it can edit files, search the project and run commands. On a project still using the older Next.js router, this pattern does not apply.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add wsimmonds/claude-nextjs-skills --skill nextjs-use-search-params-suspense -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/nextjs-use-search-params-suspense/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/nextjs-use-search-params-suspense/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add wsimmonds/claude-nextjs-skills --skill nextjs-use-search-params-suspense -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/nextjs-use-search-params-suspense/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

## When to use it
- read URL query params in a client component without breaking the build
- wrap a useSearchParams component in a Suspense boundary with a fallback
- build a search UI driven by the q parameter
- wire product filters that push updated query strings
- add blog pagination through the page parameter

## Example prompts
- add a search page that reads q from the URL with useSearchParams
- build category and sort filters that update the address via router.push
- rewrite the pagination component so it stops failing without Suspense

description: Pattern for using useSearchParams hook with Suspense boundary in Next.js. Covers the required combination of 'use client' directive and Suspense wrapper when accessing URL query parameters in client components. Use when building search interfaces, filters, pagination, or any feature that needs to read/manipulate URL query parameters client-side.

# Next.js: useSearchParams with Suspense Pattern

## Pattern Overview

**The useSearchParams hook requires TWO things:**
1. Component must have `'use client'` directive
2. Component must be wrapped in a `<Suspense>` boundary

This is a Next.js requirement, not optional!

## Why This Pattern?

**useSearchParams** reads URL query parameters:
- `/search?q=shoes` → `searchParams.get('q')` returns `"shoes"`
- `/products?category=electronics&sort=price` → Read multiple params

**Why Suspense?**
Next.js uses React 18's Suspense to handle the async nature of reading URL params during server-side rendering and hydration.

## The Pattern

### Single-File Pattern (Recommended)

```typescript
// app/page.tsx
import { Suspense } from 'react';
import SearchComponent from './SearchComponent';

export default function Page() {
  return (
    <Suspense fallback={<div>Loading...</div>}>
      <SearchComponent />
    </Suspense>
  );
}

// app/SearchComponent.tsx
'use client';

import { useSearchParams } from 'next/navigation';

export default function SearchComponent() {
  const searchParams = useSearchParams();
  const query = searchParams.get('q') || '';

  return (
    <div>
      <h1>Search Results for: {query}</h1>
    </div>
  );
}
```

### Inline Pattern (Single File)

Sometimes you want everything in one file:

```typescript
// app/page.tsx
'use client';

import { Suspense } from 'react';
import { useSearchParams } from 'next/navigation';

function SearchContent() {
  const searchParams = useSearchParams();
  const query = searchParams.get('q') || '';

  return (
    <div>
      <h1>Search: {query}</h1>
      <p>Results for "{query}"</p>
    </div>
  );
}

export default function Page() {
  return (
    <Suspense fallback={<div>Loading search...</div>}>
      <SearchContent />
    </Suspense>
  );
}
```
