title	description
Components	Nuxt Kit provides a set of utilities to help you work with components. You can register components globally or locally, and also add directories to be scanned for components.

Components

source code

Components are the building blocks of your Nuxt application. They are reusable Vue instances that can be used to create a user interface. In Nuxt, components from the components directory are automatically imported by default. However, if you need to import components from an alternative directory or wish to selectively import them as needed, @nuxt/kit provides the addComponentsDir and addComponent methods. These utils allow you to customize the component configuration to better suit your needs.

addComponentsDir

Register a directory to be scanned for components and imported only when used. Keep in mind, that this does not register components globally, until you specify global: true option.

Type

async function addComponentsDir (dir: ComponentsDir): void

interface ComponentsDir {
  path: string
  pattern?: string | string[]
  ignore?: string[]
  prefix?: string
  pathPrefix?: boolean
  enabled?: boolean
  prefetch?: boolean
  preload?: boolean
  isAsync?: boolean
  extendComponent?: (component: Component) => Promise<Component | void> | (Component | void)
  global?: boolean
  island?: boolean
  watch?: boolean
  extensions?: string[]
  transpile?: 'auto' | boolean
}

interface Component {
  pascalName: string
  kebabName: string
  export: string
  filePath: string
  shortPath: string
  chunkName: string
  prefetch: boolean
  preload: boolean
  global?: boolean
  island?: boolean
  mode?: 'client' | 'server' | 'all'
  priority?: number
}

Parameters

dir

Type: ComponentsDir

Required: true

An object with the following properties:

• path (required)
