A **page** is UI that is unique to a route.

```tsx filename="app/blog/[slug]/page.tsx" switcher
export default function Page({
  params,
  searchParams,
}: {
  params: { slug: string }
  searchParams: { [key: string]: string | string[] | undefined }
}) {
  return <h1>My Page</h1>
}
```

```jsx filename="app/blog/[slug]/page.js" switcher
export default function Page({ params, searchParams }) {
  return <h1>My Page</h1>
}
```

## Props

### `params` (optional)

An object containing the [dynamic route parameters](/docs/app/building-your-application/routing/dynamic-routes) from the root segment down to that page. For example:

| Example                              | URL         | `params`                       |
| ------------------------------------ | ----------- | ------------------------------ |
| `app/shop/[slug]/page.js`            | `/shop/1`   | `{ slug: '1' }`                |
| `app/shop/[category]/[item]/page.js` | `/shop/1/2` | `{ category: '1', item: '2' }` |
| `app/shop/[...slug]/page.js`         | `/shop/1/2` | `{ slug: ['1', '2'] }`         |

### `searchParams` (optional)

An object containing the [search parameters](https://developer.mozilla.org/en-US/docs/Learn/Common_questions/What_is_a_URL#parameters) of the current URL. For example:

| URL             | `searchParams`       |
| --------------- | -------------------- |
| `/shop?a=1`     | `{ a: '1' }`         |
| `/shop?a=1&b=2` | `{ a: '1', b: '2' }` |
| `/shop?a=1&a=2` | `{ a: ['1', '2'] }`  |

> **Good to know**:
>
> - `searchParams` is a **[Dynamic API](/docs/app/building-your-application/rendering/static-and-dynamic#dynamic-functions)** whose values cannot be known ahead of time. Using it will opt the page into **[dynamic rendering](/docs/app/building-your-application/rendering/static-and-dynamic#dynamic-rendering)** at request time.
> - `searchParams` returns a plain JavaScript object and not a `URLSearchParams` instance.
