# Pages directory
|
||
|
||
::alert{type="info"}
|
||
The `pages/` directory is optional, meaning that if you only use [app.vue](/docs/directory-structure/app), `vue-router` won't be included, reducing your application's bundle size.
|
||
::
|
||
|
||
Nuxt will automatically integrate [Vue Router](https://next.router.vuejs.org/) and map `pages/` directory into the routes of your application.
|
||
|
||
::alert{type=warning}
|
||
Unlike components, your pages must have a single root element to allow Nuxt to apply route transitions between pages.

## Dynamic Routes
|
||
|
||
If you place anything within square brackets, it will be turned into a [dynamic route](https://next.router.vuejs.org/guide/essentials/dynamic-matching.html) parameter. You can mix and match multiple parameters and even non-dynamic text within a file name or directory.
|
||
|
||
If you need a catch-all route, you create it by using a file named like `[...slug].vue`. This will match _all_ routes under that path, and thus it doesn't support any non-dynamic text.
|
||
|
||
### Example
|
||
|
||
```bash
|
||
-| pages/
|
||
---| index.vue
|
||
---| users-[group]/
|
||
-----| [id].vue
|
||
```
|
||
|
||
Given the example above, you can access group/id within your component via the `$route` object:
|
||
|
||
```vue
|
||
<template>
|
||
{{ $route.params.group }}
|
||
{{ $route.params.id }}
|
||
</template>
|
||
```
|
||
|
||
Navigating to `/users-admins/123` would render:
|
||
|
||
```text
|
||
admins 123
|
||
```
|
||
|
||
If you want to access the route using Composition API, there is a global `useRoute` function that will allow you to access the route just like `this.$route` in the Options API.
|
||
|
||
```js
|
||
<script setup>
|
||
// This import statement is optional since it's automatically imported by Nuxt.
|
||
// import { useRoute } from '#imports'
|
||
|
||
const route = useRoute()
|
||
|
||
if (route.params.group === 'admins' && !route.params.id) {
|
||
console.log('Warning! Make sure user is authenticated!')
|
||
}
|
||
</script>
|
||
```
|
||
|
||
## Navigation
|
||
|
||
To navigate between pages of your app, you should use the `<NuxtLink>` component. This component is included with Nuxt and therefore you don't have to import it as you do with other components. It is similar to the HTML `<a>` tag except that instead of using a `href="/about"` you use `to="/about"`. If you've used `vue-router` before, you can think of `<NuxtLink>` as a replacement for `<RouterLink>`.
|
||
|
||
A simple link to the `index.vue` page in your `pages` folder:
|
||
|
||
```html
|
||
<template>
|
||
<NuxtLink to="/">Home page</NuxtLink>
|
||
</template>
|
||
```
|
||
|
||
The `<NuxtLink>` component should be used for all internal links. That means for all links to the pages within your site you should use `<NuxtLink>`. The `<a>` tag should be used for all external links. That means if you have links to other websites you should use the `<a>` tag for those.
|
||
|
||
```html
|
||
<template>
|
||
<div>
|
||
<h1>Home page</h1>
|
||
<NuxtLink to="/about">
|
||
About (internal link that belongs to the Nuxt App)
|
||
</NuxtLink>
|
||
<a href="https://nuxtjs.org">External Link to another page</a>
|
||
</div>
|
||
</template>
|
||
```
|
||
|
||
::alert{type="info"}
|
||
If you want to know more about `<RouterLink>`, read the [Vue Router documentation](https://next.router.vuejs.org/api/#router-link) for more information.
|
||

||
|
||
## Nested Routes
|
||
|
||
We provide a semantic alias for `RouterView`, the `<NuxtChild>` component, for displaying the children components of a [nested route](https://next.router.vuejs.org/guide/essentials/nested-routes.html).
|
||
|
||
Example:
|
||
|
||
```bash
|
||
-| pages/
|
||
---| parent/
|
||
------| child.vue
|
||
---| parent.vue
|
||
```
|
||
|
||
This file tree will generate these routes:
|
||
|
||
```js
|
||
[
|
||
{
|
||
path: '/parent',
|
||
component: '~/pages/parent.vue',
|
||
name: 'parent',
|
||
children: [
|
||
{
|
||
path: 'child',
|
||
component: '~/pages/parent/child.vue',
|
||
name: 'parent-child'
|
||
}
|
||
]
|
||
}
|
||
]
|
||
```
|
||
|
||
To display the `child.vue` component, you have to insert the `<NuxtChild>` component inside `pages/parent.vue`:
|
||
|
||
```html{}[pages/parent.vue]
|
||
<template>
|
||
<div>
|
||
<h1>I am the parent view</h1>
|
||
<NuxtChild :foobar="123" />
|
||
</div>
|
||
</template>
|
||
```
