In Nuxt 3, routes are automatically generated based on the structure of the files in the pages directory. However, there may be scenarios where you'd want to customize these routes. For instance, you might need to add a route for a dynamic page not generated by Nuxt, remove an existing route, or modify the configuration of a route. For such customizations, Nuxt 3 offers the extendPages feature, which allows you to extend and alter the pages configuration.

Type

function extendPages (callback: (pages: NuxtPage[]) => void): void

type NuxtPage = {
  name?: string
  path: string
  file?: string
  meta?: Record<string, any>
  alias?: string[] | string
  redirect?: RouteLocationRaw
  children?: NuxtPage[]
}

Parameters

`callback`

Type: (pages: NuxtPage[]) => void

Required: true

A function that will be called with the pages configuration. You can alter this array by adding, deleting, or modifying its elements. Note: You should modify the provided pages array directly, as changes made to a copied array will not be reflected in the configuration.

Examples

// https://github.com/nuxt-modules/prismic/blob/master/src/module.ts
import { createResolver, defineNuxtModule, extendPages } from '@nuxt/kit'

export default defineNuxtModule({
  setup(options) {
    const resolver = createResolver(import.meta.url)

    extendPages((pages) => {
      pages.unshift({
        name: 'prismic-preview',
        path: '/preview',
        file: resolver.resolve('runtime/preview.vue')
       })
    })
  }
})

`extendRouteRules`

Nuxt is powered by the Nitro server engine. With Nitro, you can incorporate high-level logic directly into your configuration, which is useful for actions like redirects, proxying, caching, and appending headers to routes. This configuration works by associating route patterns with specific route settings.

👉

You can read more about Nitro route rules in the Nitro documentation.

Type

function extendRouteRules (route: string, rule: NitroRouteConfig, options: ExtendRouteRulesOptions): void

interface NitroRouteConfig {
  cache?: CacheOptions | false;
  headers?: Record<string, string>;
  redirect?: string | { to: string; statusCode?: HTTPStatusCode };
  prerender?: boolean;
  proxy?: string | ({ to: string } & ProxyOptions);
  isr?: number | boolean;
  cors?: boolean;
  swr?: boolean | number;
  static?: boolean | number;
}

interface ExtendRouteRulesOptions {
  override?: boolean
}

interface CacheOptions {
  swr?: boolean
  name?: string
  group?: string
  integrity?: any
  maxAge?: number
  staleMaxAge?: number
  base?: string
  headersOnly?: boolean
}

// See https://www.jsdocs.io/package/h3#ProxyOptions
interface ProxyOptions {
  headers?: RequestHeaders | HeadersInit;
  fetchOptions?: RequestInit & { duplex?: Duplex } & {
    ignoreResponseError?: boolean;
  };
  fetch?: typeof fetch;
  sendStream?: boolean;
  streamRequest?: boolean;
  cookieDomainRewrite?: string | Record<string, string>;
  cookiePathRewrite?: string | Record<string, string>;
  onResponse?: (event: H3Event, response: Response) => void;
}

Parameters

`route`

Type: string

Required: true

A route pattern to match against.

`rule`

Type: NitroRouteConfig

Required: true

A route configuration to apply to the matched route.

`options`

Type: ExtendRouteRulesOptions

Default: {}

Options to pass to the route configuration. If override is set to true, it will override the existing route configuration.

Examples

// https://github.com/directus/website/blob/main/modules/redirects.ts
import { createResolver, defineNuxtModule, extendRouteRules, extendPages } from '@nuxt/kit'

export default defineNuxtModule({
  setup(options) {
    const resolver = createResolver(import.meta.url)

    extendPages((pages) => {
      pages.unshift({
        name: 'preview-new',
        path: '/preview-new',
        file: resolver.resolve('runtime/preview.vue')
       })
    })

    extendRouteRules('/preview', {
      redirect: {
        to: '/preview-new',
        statusCode: 302
      }
    })

    extendRouteRules('/preview-new', {
      cache: {
        maxAge: 60 * 60 * 24 * 7
      }
    })
  }
})

`addRouteMiddleware`

Registers route middlewares to be available for all routes or for specific routes.

Route middlewares can be also defined in plugins via addRouteMiddleware composable.

👉

Read more about route middlewares in the Route middleware documentation.

Type

function addRouteMiddleware (input: NuxtMiddleware | NuxtMiddleware[], options: AddRouteMiddlewareOptions): void

type NuxtMiddleware = {
  name: string
  path: string
  global?: boolean
}

interface AddRouteMiddlewareOptions {
  override?: boolean
}

Parameters

`input`

Type: NuxtMiddleware | NuxtMiddleware[]

Required: true

A middleware object or an array of middleware objects with the following properties:

name (required)
Type: string
Middleware name.
path (required)
Type: string
Path to the middleware.
global (optional)
Type: boolean
If enabled, registers middleware to be available for all routes.

`options`

Type: AddRouteMiddlewareOptions

Default: {}

Options to pass to the middleware. If override is set to true, it will override the existing middleware with the same name.

Examples

runtime/auth.ts

export default defineNuxtRouteMiddleware((to, from) => {
  // isAuthenticated() is an example method verifying if a user is authenticated
  if (to.path !== '/login' && isAuthenticated() === false) {
    return navigateTo('/login')
  }
})
