# Components directory

The `components/` directory is where you put all your Vue components which can then be imported inside your pages or other components ([learn more](https://v3.vuejs.org/guide/component-basics.html)).

Nuxt automatically imports any components in your `components/` directory (along with components that are registered by any modules you may be using).

```bash
| components/
--| TheHeader.vue
--| TheFooter.vue
```

```html{}[layouts/default.vue]
<template>
  <div>
    <TheHeader />
    <Nuxt />
    <TheFooter />
  </div>
</template>
```

## Component Names

If you have components in nested directories such as:

```bash
| components/
--| base/
----| foo/
------| Button.vue
```

The component name will be based on its own path directory and filename, with duplicate segments being removed. Therefore, the component will be:

```html
<BaseFooButton />
```

::alert
For clarity, it is recommended that the component file name matches its name. (So, in the example above, you could rename `Button.vue` to be `BaseFooButton.vue`.)

## Dynamic Imports

To dynamically import a component (also known as lazy-loading a component) all you need to do is add the `Lazy` prefix to the component name.

```html{}[layouts/default.vue]
<template>
  <div>
    <TheHeader />
    <Nuxt />
    <LazyTheFooter />
  </div>
</template>
```

This is particularly useful if the component is not always needed. By using the `Lazy` prefix you can delay loading the component code until the right moment, which can be helpful for optimizing your JavaScript bundle size.

```html{}[pages/index.vue]
<template>
  <div>
    <h1>Mountains</h1>
    <LazyMountainsList v-if="show" />
    <button v-if="!show" @click="show = true">Show List</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      show: false
    }
  }
}
</script>
```

## `<ClientOnly>` Component

Nuxt provides the `<ClientOnly>` component for purposely rendering a component only on client-side. To import a component only on the client, register the component in a client-side only plugin.

```html{}[pages/example.vue]
<template>
  <div>
    <Sidebar />
    <ClientOnly>
      <!-- this component will only be rendered on client-side -->
      <Comments />
    </ClientOnly>
  </div>
</template>
```

Use a slot as fallback until `<ClientOnly>` is mounted on client-side.

```html{}[pages/example.vue]
<template>
  <div>
    <Sidebar />
    <ClientOnly>
      <!-- this component will only be rendered on client-side -->
      <Comments />
      <template #fallback>
        <!-- this will be rendered on server-side -->
        <p>Loading comments...</p>
      </template>
    </ClientOnly>
  </div>
</template>
```

## Library Authors

Making Vue component libraries with automatic tree-shaking and component registration is super easy ✨

You can use the `components:dirs` hook to easily extend the directory list without requiring user configuration in your Nuxt module.

Imagine a directory structure like this:

```bash
| node_modules/
---| awesome-ui/
------| components/
---------| Alert.vue
---------| Button.vue
------| nuxt.js
| pages/
---| index.vue
| nuxt.config.js
```

Then in `awesome-ui/nuxt.js` you can use the `components:dirs` hook:

```js
import { join } from 'pathe'
import { defineNuxtModule } from '@nuxt/kit'

export default defineNuxtModule({
  hooks: {
    'components:dirs'(dirs) {
      // Add ./components dir to the list
      dirs.push({
        path: join(__dirname, 'components'),
        prefix: 'awesome'
      })
    }
  }
})
```

That's it! Now in your project, you can import your ui library as a Nuxt module in your `nuxt.config.js`:

```js
export default {
  buildModules: ['awesome-ui/nuxt']
}
```

And directly use the module components (prefixed with `awesome-`), our `pages/index.vue`:

```vue
<template>
  <div>
    My <AwesomeButton>UI button</AwesomeButton>!
    <awesome-alert>Here's an alert!</awesome-alert>
  </div>
</template>
```

It will automatically import the components only if used and also support HMR when updating your components in `node_modules/awesome-ui/components/`.
