## Adding custom routes

In Nuxt 3, your routing is defined by the structure of your files inside the [pages directory](/docs/guide/directory-structure/pages). However, since it uses [vue-router](https://router.vuejs.org) under the hood, Nuxt offers you several ways to add custom routes in your project.

### Router Config

Using [router options](/docs/guide/going-further/custom-routing#router-options), you can optionally override or extend your routes using a function that accepts the scanned routes and returns customized routes.

If it returns `null` or `undefined`, Nuxt will fall back to the default routes (useful to modify input array).

```ts [app/router.options.ts]
import type { RouterConfig } from '@nuxt/schema'

export default <RouterConfig> {
  // https://router.vuejs.org/api/interfaces/routeroptions.html#routes
  routes: (_routes) => [
    {
      name: 'home',
      path: '/',
      component: () => import('~/pages/home.vue').then(r => r.default || r)
    }
  ],
}
```

::callout
Nuxt will not augment any new routes you return from the `routes` function with metadata defined in `definePageMeta` of the component you provide. If you want that to happen, you should use the `pages:extend` hook which is [called at build-time](/docs/api/advanced/hooks#nuxt-hooks-build-time).
::

### Pages Hook

You can add, change or remove pages from the scanned routes with the `pages:extend` nuxt hook.

For example, to prevent creating routes for any `.ts` files:

```ts [nuxt.config.ts]
export default defineNuxtConfig({
  hooks: {
    'pages:extend' (pages) {
      // add a route
      pages.push({
        name: 'profile',
        path: '/profile',
        file: '~/extra-pages/profile.vue'
      })

      // remove routes
      function removePagesMatching (pattern: RegExp, pages: NuxtPage[] = []) {
        const pagesToRemove = []
        for (const page of pages) {
          if (pattern.test(page.file)) {
            pagesToRemove.push(page)
          } else {
            removePagesMatching(pattern, page.children)
          }
        }
        for (const page of pagesToRemove) {
          pages.splice(pages.indexOf(page), 1)
        }
      }
      removePagesMatching(/\.ts$/, pages)
    }
  }
})
```

### Nuxt Module

If you plan to add a whole set of pages related with a specific functionality, you might want to use a [Nuxt module](/modules).

The [Nuxt kit](/docs/guide/going-further/kit) provides a few ways [to add routes](/docs/api/kit/pages):
- [`extendPages`](/docs/api/kit/pages#extendpages) (callback: pages => void)
- [`extendRouteRules`](/docs/api/kit/pages#extendrouterules) (route: string, rule: NitroRouteConfig, options: ExtendRouteRulesOptions)

## Router Options

On top of customizing options for [`vue-router`](https://router.vuejs.org/api/interfaces/routeroptions.html), Nuxt offers [additional options](/docs/api/nuxt-config#router) to customize the router.

### Using `app/router.options`

This is the recommended way to specify [router options](/docs/api/nuxt-config#router).

```js [app/router.options.ts]
import type { RouterConfig } from '@nuxt/schema'

export default <RouterConfig> {
}
```

### Using `nuxt.config`

**Note:** Only JSON serializable [options](/docs/api/nuxt-config#router) are configurable:

- `linkActiveClass`
- `linkExactActiveClass`
- `end`
- `sensitive`
- `strict`
- `hashMode`
- `scrollBehaviorType`

```js [nuxt.config]
export default defineNuxtConfig({
  router: {
    options: {}
  }
})
```

### Hash Mode (SPA)

You can enable hash history in SPA mode using the `hashMode` [config](/docs/api/nuxt-config#router). In this mode, router uses a hash character (#) before the actual URL that is internally passed. When enabled, the **URL is never sent to the server** and **SSR is not supported**.

```ts [nuxt.config.ts]
export default defineNuxtConfig({
  ssr: false,
  router: {
    options: {
      hashMode: true
    }
  }
})
```

### Scroll Behavior for hash links

You can optionally customize the scroll behavior for hash links. When you set the [config](/docs/api/nuxt-config#router) to be `smooth` and you load a page with a hash link (e.g. `https://example.com/blog/my-article#comments`), you will see that the browser smoothly scrolls to this anchor.
  
```ts [nuxt.config.ts]
export default defineNuxtConfig({
  router: {
    options: {
      scrollBehaviorType: 'smooth'
    }
  }
})
```

#### Custom History (advanced)

You can optionally override history mode using a function that accepts the base URL and returns the history mode. If it returns `null` or `undefined`, Nuxt will fallback to the default history.

```js [app/router.options.ts]
import type { RouterConfig } from '@nuxt/schema'
import { createMemoryHistory } from 'vue-router'

export default <RouterConfig> {
  // https://router.vuejs.org/api/interfaces/routeroptions.html
  history: base => process.client ? createMemoryHistory(base) : null /* default */
}
```
