+
+# The &lt;nuxt-child&gt; Component
+
+> This component is used for displaying the children components in a [nested route](/guide/routing#nested-routes).
+
+Example:
+
+```bash
+-| pages/
+---| parent/
+------| child.vue
+---| parent.vue
+```
+
+This file tree will generate these routes:
+```js
+[
+  {
+    path: '/parent',
+    component: '~pages/parent.vue',
+    name: 'parent',
+    children: [
+      {
+        path: 'child',
+        component: '~pages/parent/child.vue',
+        name: 'parent-child'
+      }
+    ]
+  }
+]
+```
+
+To display the `child.vue` component, I have to insert `<nuxt-child/>` inside `pages/parent.vue`:
+
+```html
+<template>
+  <div>
+    <h1>I am the parent view</h1>
+    <nuxt-child/>
+  </div>
+</template>
+```
+
+To see an example, take a look at the [nested-routes example](/examples/nested-routes).

+# The &lt;nuxt-link&gt; Component
+
+> This component is used to link the page components between them.
+
+At the moment, `<nuxt-link>` is the same as [`<router-link>`](https://router.vuejs.org/en/api/router-link.html), so we recommend you to see how to use it on the [vue-router documentation](https://router.vuejs.org/en/api/router-link.html).
+
+Example (`pages/index.vue`):
+
+```html
+<template>
+  <div>
+    <h1>Home page</h1>
+    <nuxt-link to="/about">About</nuxt-link>
+  </div>
+</template>
+```
+
+In the future, we will add features to the nuxt-link component, like pre-fetching on the background for improving the responsiveness of nuxt.js applications.

+
+## analyze
+
+> Nuxt.js use [webpack-bundle-analyzer](https://github.com/th0r/webpack-bundle-analyzer) to let you visualize your bundles and how to optimize them.
+
+- Type: `Boolean` or `Object`
+- Default: `false`
+
+If an object, see available properties [here](https://github.com/th0r/webpack-bundle-analyzer#as-plugin).
+
+Example (`nuxt.config.js`):
+```js
+module.exports = {
+  build: {
+    analyze: true
+    // or
+    analyze: {
+      analyzerMode: 'static'
+    }
+  }
+}
+```
+
+<p class="Alert Alert--teal">**INFO:** You can use the command `nuxt build --analyzer` or `nuxt build -a` to build your application and launch the bundle analyzer on [http://localhost:8888](http://localhost:8888)</p>
+
+## babel

+
+## extend
+
+- Type: `Function`
+

+
+The extend is called twice, one time for the server bundle, and one time for the client bundle. The arguments of the method are:
+1. Webpack config object
+2. Object with the folowing keys (all boolean): `dev`, `isClient`, `isServer`
+
+Example (`nuxt.config.js`):
+```js
+module.exports = {
+  build: {
+    extend (config, { isClient }) {
+      // Extend only webpack config for client-bundle
+      if (isClient) {
+        config.devtool = 'eval-source-map'
+      }
+    }
+  }
+}

+      }
+    ]

+    ]
+  }
+}
+```
+
+## vendor
+
+> Nuxt.js lets you add modules inside the `vendor.bundle.js` file generated to reduce the size of the app bundle. It's really useful when using external modules (like `axios` for example)
+
+- **Type:** `Array`
+ - **Items:** `String`
+
+To add a module/file inside the vendor bundle, add the `build.vendor` key inside `nuxt.config.js`:

+module.exports = {
+  build: {
+    vendor: ['axios']
+  }
+}
+```
+
+You can also give a path to a file, like a custom lib you created:

+# The cache Property
+
+> Nuxt.js use [lru-cache](https://github.com/isaacs/node-lru-cache) to allow cached components for better render performances
+
+## Usage
+
+- **Type:** `Boolean` or `Object` (Default: `false`)
+
+If an object, see [lru-cache options](https://github.com/isaacs/node-lru-cache#options).
+
+Use the `cache` key in your `nuxt.config.js`:
+```js
+module.exports = {
+  cache: true
+  // or
+  cache: {
+    max: 1000,
+    maxAge: 900000
+  }
+}
+```
+
+If `cache` is set to  `true` the default keys given are:
+
+| key  | Optional? | Type | Default | definition |
+|------|------------|-----|---------|------------|
+| `max` | Optional | Integer | 1000 | The maximum size of the cached components, when the 1001 is added, the first one added will be removed from the cache to let space for the new one. |
+| `maxAge` | Optional | Integer | 900000 | Maximum age in ms, default to 15 minutes. |
