+description: Extending Nuxt applications with layers for code sharing and reusability
+---
+
+# Nuxt Layers
+
+Layers allow sharing and reusing partial Nuxt applications across projects. They can include components, composables, pages, layouts, and configuration.
+
+## Using Layers
+
+### From npm Package
+
+```ts
+// nuxt.config.ts
+export default defineNuxtConfig({
+  extends: [
+    '@my-org/base-layer',
+    '@nuxtjs/ui-layer',
+  ],
+})
+```
+
+### From Git Repository
+
+```ts
+// nuxt.config.ts
+export default defineNuxtConfig({
+  extends: [
+    'github:username/repo',
+    'github:username/repo/base', // Subdirectory
+    'github:username/repo#v1.0', // Specific tag
+    'github:username/repo#dev', // Branch
+    'gitlab:username/repo',
+    'bitbucket:username/repo',
+  ],
+})
+```
+
+### From Local Directory
+
+```ts
+// nuxt.config.ts
+export default defineNuxtConfig({
+  extends: [
+    '../base-layer',
+    './layers/shared',
+  ],
+})
+```
+
+### Auto-scanned Layers
+
+Place in `layers/` directory for automatic discovery:
+
+```
+my-app/
+├── layers/
+│   ├── base/
+│   │   └── nuxt.config.ts
+│   └── ui/
+│       └── nuxt.config.ts
+└── nuxt.config.ts
+```
+
+## Creating a Layer
+
+Minimal layer structure:
+
+```
+my-layer/
+├── nuxt.config.ts       # Required
+├── app/
+│   ├── components/      # Auto-merged
+│   ├── composables/     # Auto-merged
+│   ├── layouts/         # Auto-merged
+│   ├── middleware/      # Auto-merged
+│   ├── pages/           # Auto-merged
+│   ├── plugins/         # Auto-merged
+│   └── app.config.ts    # Merged
+├── server/              # Auto-merged
+└── package.json
+```
+
+### Layer nuxt.config.ts
+
+```ts
+// my-layer/nuxt.config.ts
+export default defineNuxtConfig({
+  // Layer configuration
+  app: {
+    head: {
+      title: 'My Layer App',
+    },
+  },
+  // Shared modules
+  modules: ['@nuxt/ui'],
+})
+```
+
+### Layer Components
+
+```vue
+<!-- my-layer/app/components/BaseButton.vue -->
+<template>
+  <button class="base-btn">
+    <slot />
+  </button>
+</template>
+```
+
+Use in consuming project:
+
+```vue
+<template>
+  <BaseButton>Click me</BaseButton>
+</template>
+```
+
+### Layer Composables
+
+```ts
+// my-layer/app/composables/useTheme.ts
+export function useTheme() {
+  const isDark = useState('theme-dark', () => false)
+  const toggle = () => isDark.value = !isDark.value
+  return { isDark, toggle }
+}
+```
+
+## Layer Priority
+
+Override order (highest to lowest):
+1. Your project files
+2. Auto-scanned layers (alphabetically, Z > A)
+3. `extends` array (first > last)
+
+Control order with prefixes:
+
+```
+layers/
+├── 1.base/      # Lower priority
+└── 2.theme/     # Higher priority
+```
+
+## Layer Aliases
+
+Access layer files:
+
+```ts
+// Auto-scanned layers get aliases
+import Component from '#layers/base/components/Component.vue'
+```
+
+Named aliases:
+
+```ts
+// my-layer/nuxt.config.ts
+export default defineNuxtConfig({
+  $meta: {
+    name: 'my-layer',
+  },
+})
+```
+
+```ts
+// In consuming project
+import { something } from '#layers/my-layer/utils'
+```
+
+## Publishing Layers
+
+### As npm Package
+
+```json
+{
+  "name": "my-nuxt-layer",
+  "version": "1.0.0",
+  "type": "module",
+  "main": "./nuxt.config.ts",
+  "dependencies": {
+    "@nuxt/ui": "^2.0.0"
+  },
+  "devDependencies": {
+    "nuxt": "^3.0.0"
+  }
+}
+```
+
+### Private Layers
+
+For private git repos:
+
+```bash
+export GIGET_AUTH=<github-token>
+```
+
+## Layer Best Practices
+
+### Use Resolved Paths
+
+```ts
+// my-layer/nuxt.config.ts
+import { fileURLToPath } from 'node:url'
+import { dirname, join } from 'node:path'
+
+const currentDir = dirname(fileURLToPath(import.meta.url))
+
+export default defineNuxtConfig({
+  css: [
+    join(currentDir, './assets/main.css'),
+  ],
+})
+```
+
+### Install Dependencies
+
+```ts
+// nuxt.config.ts
+export default defineNuxtConfig({
+  extends: [
+    ['github:user/layer', { install: true }],
+  ],
+})
+```
+
+### Disable Layer Modules
+
+```ts
+// nuxt.config.ts
+export default defineNuxtConfig({
+  extends: ['./base-layer'],
+  // Disable modules from layer
+  image: false, // Disables @nuxt/image
+  pinia: false, // Disables @pinia/nuxt
+})
+```
+
+## Starter Template
+
+Create a new layer:
+
+```bash
+npx nuxi init --template layer my-layer
+```
+
+## Example: Theme Layer
+
+```
+theme-layer/
+├── nuxt.config.ts
+├── app/
+│   ├── app.config.ts
+│   ├── components/
+│   │   ├── ThemeButton.vue
+│   │   └── ThemeCard.vue
+│   ├── composables/
+│   │   └── useTheme.ts
+│   └── assets/
+│       └── theme.css
+└── package.json
+```
+
+```ts
+// theme-layer/nuxt.config.ts
+export default defineNuxtConfig({
+  css: ['~/assets/theme.css'],
+})
+```
+
+```ts
+// theme-layer/app/app.config.ts
+export default defineAppConfig({
+  theme: {
+    primaryColor: '#00dc82',
+    darkMode: false,
+  },
+})
+```
+
+```ts
+// consuming-app/nuxt.config.ts
+export default defineNuxtConfig({
+  extends: ['theme-layer'],
+})
+
+// consuming-app/app/app.config.ts
+export default defineAppConfig({
+  theme: {
+    primaryColor: '#ff0000', // Override
+  },
+})
+```
