Layers

One of the core features of Nuxt 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.

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 module presets
• Share standard setup across projects
• Create Nuxt themes
• Enhance code organization by implementing a modular architecture and support Domain-Driven Design (DDD) pattern in large scale projects.

Usage

By default, any layers within your project in the ~/layers directory will be automatically registered as layers in your project

In addition, you can extend from a layer by adding the extends property to your nuxt.config 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
  ]
})

You can also pass an authentication token if you are extending from a private GitHub repository:

export default defineNuxtConfig({
  extends: [
    // per layer configuration
    ['github:my-themes/private-awesome', { auth: process.env.GITHUB_TOKEN }]
  ]
})

Nuxt uses unjs/c12 and unjs/giget for extending remote layers. Check the documentation for more information and all available options.
