One of the core features of Nuxt 3 is the layers and extending support. You can extend a default Nuxt application to reuse components, utils, and configuration. The layers structure is almost identical to a standard Nuxt application which makes them easy to author and maintain. Some example use cases:

  • Share reusable configuration presets across projects using nuxt.config and app.config
  • Create a component library using components/ directory
  • Create utility and composable library using composables/ and utils/ directories
  • Create Nuxt themes
  • Create Nuxt module presets
  • Share standard setup across projects

You can extend a layer by adding the extends property to the nuxt.config.ts file.

export default defineNuxtConfig({  extends: [    '../base',                     // Extend from a local layer    '@my-themes/awesome',          // Extend from an installed npm package    'github:my-themes/awesome#v1', // Extend from a git repository  ]})
