This page will guide you through how to create layouts and pages, and link between them. ## Creating a page A **page** is UI that is rendered on a specific route. To create a page, add a [`page` file](/docs/app/api-reference/file-conventions/page) inside the `app` directory and default export a React component. For example, to create an index page (`/`): page.js special file ```tsx filename="app/page.tsx" switcher export default function Page() { return

Hello Next.js!

} ``` ```jsx filename="app/page.js" switcher export default function Page() { return

Hello Next.js!

} ``` ## Creating a layout A layout is UI that is **shared** between multiple pages. On navigation, layouts preserve state, remain interactive, and do not rerender. You can define a layout by default exporting a React component from a [`layout` file](/docs/app/api-reference/file-conventions/layout). The component should accept a `children` prop which can be a page or another [layout](#nesting-layouts). For example, to create a layout that accepts your index page as child, add a `layout` file inside the `app` directory: layout.js special file ```tsx filename="app/layout.tsx" switcher export default function DashboardLayout({ children, }: { children: React.ReactNode }) { return ( {/* Layout UI */} {/* Place children where you want to render a page or nested layout */}
{children}
) } ``` ```jsx filename="app/layout.js" switcher export default function DashboardLayout({ children }) { return ( {/* Layout UI */} {/* Place children where you want to render a page or nested layout */}
{children}
) } ``` The layout above is called a [root layout](/docs/app/api-reference/file-conventions/layout#root-layout) because it's defined at the root of the `app` directory. The root layout is **required** and must contain `html` and `body` tags. ## Creating a nested route A nested route is a route composed of multiple URL segments. For example, the `/blog/[slug]` route is composed of three segments: - `/` (Root Segment) - `blog` (Segment) - `[slug]` (Leaf Segment) In Next.js: - **Folders** are used to define the route segments that map to URL segments. - **Files** (like `page` and `layout`) are used to create UI that is shown for a segment. To create nested routes, you can nest folders inside each other. For example, to add a route for `/blog`, create a folder called `blog` in the `app` directory. Then, to make `/blog` publicly accessible, add a `page.tsx` file: File hierarchy showing blog folder and a page.js file ```tsx filename="app/blog/page.tsx" switcher // Dummy imports import { getPosts } from '@/lib/posts' import { Post } from '@/ui/post' export default async function Page() { const posts = await getPosts() return ( ) } ``` ```jsx filename="app/blog/[slug]/page.js" switcher // Dummy imports import { getPosts } from '@/lib/posts' import { Post } from '@/ui/post' export default async function Page() { const posts = await getPosts() return ( ) } ``` You can continue nesting folders to create nested routes. For example, to create a route for a specific blog post, create a new `[slug]` folder inside `blog` and add a `page` file: File hierarchy showing blog folder with a nested slug folder and a page.js file ```tsx filename="app/blog/[slug]/page.tsx" switcher function generateStaticParams() {} export default function Page() { return

Hello, Blog Post Page!

} ``` ```jsx filename="app/blog/[slug]/page.js" switcher function generateStaticParams() {} export default function Page() { return

Hello, Blog Post Page!

} ``` Wrapping a folder name in square brackets (e.g. `[slug]`) creates a [dynamic route segment](/docs/app/api-reference/file-conventions/dynamic-routes) which is used to generate multiple pages from data. e.g. blog posts, product pages, etc. ## Nesting layouts By default, layouts in the folder hierarchy are also nested, which means they wrap child layouts via their `children` prop. You can nest layouts by adding `layout` inside specific route segments (folders). For example, to create a layout for the `/blog` route, add a new `layout` file inside the `blog` folder. File hierarchy showing root layout wrapping the blog layout ```tsx filename="app/blog/layout.tsx" switcher export default function BlogLayout({ children, }: { children: React.ReactNode }) { return
{children}
} ``` ```jsx filename="app/blog/layout.js" switcher export default function BlogLayout({ children }) { return
{children}
} ``` If you were to combine the two layouts above, the root layout (`app/layout.js`) would wrap the blog layout (`app/blog/layout.js`), which would wrap the blog (`app/blog/page.js`) and blog post page (`app/blog/[slug]/page.js`). ## Creating a dynamic segment [Dynamic segments](/docs/app/api-reference/file-conventions/dynamic-routes) allow you to create routes that are generated from data. For example, instead of manually creating a route for each individual blog post, you can create a dynamic segment to generate the routes based on blog post data. To create a dynamic segment, wrap the segment (folder) name in square brackets: `[segmentName]`. For example, in the `app/blog/[slug]/page.tsx` route, the `[slug]` is the dynamic segment. ```tsx filename="app/blog/[slug]/page.tsx" switcher export default async function BlogPostPage({ params, }: { params: Promise<{ slug: string }> }) { const { slug } = await params const post = await getPost(slug) return (

{post.title}

{post.content}

) } ``` ```jsx filename="app/blog/[slug]/page.js" switcher export default async function BlogPostPage({ params }) { const { slug } = await params const post = await getPost(slug) return (

{post.title}

{post.content}

) } ``` Learn more about [Dynamic Segments](/docs/app/api-reference/file-conventions/dynamic-routes) and the [`params`](/docs/app/api-reference/file-conventions/page#params-optional) props. Nested [layouts within Dynamic Segments](/docs/app/api-reference/file-conventions/layout#params-optional), can also access the `params` props. ## Rendering with search params In a Server Component **page**, you can access search parameters using the [`searchParams`](/docs/app/api-reference/file-conventions/page#searchparams-optional) prop: ```tsx filename="app/page.tsx" switcher export default async function Page({ searchParams, }: { searchParams: Promise<{ [key: string]: string | string[] | undefined }> }) { const filters = (await searchParams).filters } ``` ```jsx filename="app/page.jsx" switcher export default async function Page({ searchParams }) { const filters = (await searchParams).filters } ``` Using `searchParams` opts your page into [**dynamic rendering**](/docs/app/getting-started/partial-prerendering#dynamic-rendering) because it requires a incoming request to read the search parameters from. Client Components can read search params using the [`useSearchParams`](/docs/app/api-reference/functions/use-search-params) hook. Learn more about `useSearchParams` in [statically rendered](/docs/app/api-reference/functions/use-search-params#static-rendering) and [dynamically rendered](/docs/app/api-reference/functions/use-search-params#dynamic-rendering) routes. ### What to use and when - Use the `searchParams` prop when you need search parameters to **load data for the page** (e.g. pagination, filtering from a database). - Use `useSearchParams` when search parameters are used **only on the client** (e.g. filtering a list already loaded via props). - As a small optimization, you can use `new URLSearchParams(window.location.search)` in **callbacks or event handlers** to read search params without triggering re-renders. ## Linking between pages You can use the [`` component](/docs/app/api-reference/components/link) to navigate between routes. `` is a built-in Next.js component that extends the HTML `` tag to provide [prefetching](/docs/app/getting-started/linking-and-navigating#prefetching) and [client-side navigation](/docs/app/getting-started/linking-and-navigating#client-side-transitions). For example, to generate a list of blog posts, import `` from `next/link` and pass a `href` prop to the component: ```tsx filename="app/ui/post.tsx" highlight={1,10} switcher import Link from 'next/link' export default async function Post({ post }) { const posts = await getPosts() return ( ) } ``` ```jsx filename="app/ui/post.js" highlight={1,10} switcher import Link from 'next/link' export default async function Post({ post }) { const posts = await getPosts() return ( ) } ``` > **Good to know**: `` is the primary way to navigate between routes in Next.js. You can also use the [`useRouter` hook](/docs/app/api-reference/functions/use-router) for more advanced navigation.
