## `app.vue`
By default, Nuxt will treat this file as the **entrypoint** and render its content for every route of the application.
```vue [app.vue]
Welcome to the homepage
```
::tip
If you are familiar with Vue, you might wonder where `main.js` is (the file that normally creates a Vue app). Nuxt does this behind the scene.
::
## Components
Most components are reusable pieces of the user interface, like buttons and menus. In Nuxt, you can create these components in the [`components/`](/docs/guide/directory-structure/components) directory, and they will be automatically available across your application without having to explicitly import them.
::code-group
```vue [app.vue]
Welcome to the homepage
This is an auto-imported component.
```
```vue [components/AppAlert.vue]
```
::
## Pages
Pages represent views for each specific route pattern. Every file in the [`pages/`](/docs/guide/directory-structure/pages) directory represents a different route displaying its content.
To use pages, create `pages/index.vue` file and add `` component to the [`app.vue`](/docs/guide/directory-structure/app) (or remove `app.vue` for default entry). You can now create more pages and their corresponding routes by adding new files in the [`pages/`](/docs/guide/directory-structure/pages) directory.
::code-group
```vue [pages/index.vue]
Welcome to the homepage
This is an auto-imported component
```
```vue [pages/about.vue]
This page will be displayed at the /about route.
```

## Layouts
Layouts are wrappers around pages that contain a common User Interface for several pages, such as a header and footer display. Layouts are Vue files using `` components to display the **page** content. The `layouts/default.vue` file will be used by default. Custom layouts can be set as part of your page metadata.
::note
If you only have a single layout in your application, we recommend using [`app.vue`](/docs/guide/directory-structure/app) with [``](/docs/api/components/nuxt-page) instead.
::
::code-group
```vue [app.vue]
```
```vue [layouts/default.vue]
```
```vue [pages/index.vue]
Welcome to the homepage
This is an auto-imported component
```
```vue [pages/about.vue]
This page will be displayed at the /about route.
```
::
If you want to create more layouts and learn how to use them in your pages, find more information in the [Layouts section](/docs/guide/directory-structure/layouts).
## Advanced: Extending the HTML Template
::note
If you only need to modify the ``, you can refer to the [SEO and meta section](/docs/getting-started/seo-meta).
::
You can have full control over the HTML template by adding a Nitro plugin that registers a hook.
The callback function of the `render:html` hook allows you to mutate the HTML before it is sent to the client.
```ts twoslash [server/plugins/extend-html.ts]
export default defineNitroPlugin((nitroApp) => {
nitroApp.hooks.hook('render:html', (html, { event }) => {
// This will be an object representation of the html template.
console.log(html)
html.head.push(``)
})
// You can also intercept the response here.
nitroApp.hooks.hook('render:response', (response, { event }) => { console.log(response) })
})
```
