# App File
|
|
|
|
The `app.vue` file is the main component in your Nuxt 3 applications.
|
|
|
|
## Minimal Usage
|
|
|
|
With Nuxt 3, the [`pages/`](/guide/directory-structure/pages) directory is optional. If not present, Nuxt won't include [vue-router](https://router.vuejs.org/) dependency. This is useful when working on a landing page or an application that does not need routing.
|
|
|
|
```vue [app.vue]
|
|
<template>
|
|
<h1>Hello World!</h1>
|
|
</template>
|
|
```
|
|
|
|
## Usage With Pages
|
|
|
|
If you have a [`pages/`](/guide/directory-structure/pages) directory, to display the current page, use the `<NuxtPage>` component:
|
|
|
|
```vue [app.vue]
|
|
<template>
|
|
<div>
|
|
<NuxtLayout>
|
|
<NuxtPage/>
|
|
</NuxtLayout>
|
|
</div>
|
|
</template>
|
|
```
|
|
|
|
::alert{type=danger}
|
|
Since Nuxt 3 uses [`<Suspense>`](https://vuejs.org/guide/built-ins/suspense.html#suspense) inside `<NuxtPage>`, it cannot be set as a root element.
|
|
::
|
|
|
|
::alert{type=warning}
|
|
Remember that `app.vue` acts as the main component of your Nuxt application. Anything you add to it (JS and CSS) will be global and included in every page.
|
|
::
|
|
|
|
If you want to have the possibility to customize the structure around the page between pages, check out the [`layouts/`](/guide/directory-structure/layouts) directory.
