```vue [pages/index.vue]
|
|
<script setup lang="ts">
|
|
const router = useRouter()
|
|
</script>
|
|
```
|
|
|
|
If you only need the router instance within your template, use `$router`:
|
|
|
|
```vue [pages/index.vue]
|
|
<template>
|
|
<button @click="$router.back()">Back</button>
|
|
</template>
|
|
```
|
|
|
|
If you have a `pages/` directory, `useRouter` is identical in behavior to the one provided by `vue-router`.

Read `vue-router` documentation about the `Router` interface.

## Basic Manipulation
|
|
|
|
- [`addRoute()`](https://router.vuejs.org/api/interfaces/Router.html#addRoute): Add a new route to the router instance. `parentName` can be provided to add new route as the child of an existing route.
|
|
- [`removeRoute()`](https://router.vuejs.org/api/interfaces/Router.html#removeRoute): Remove an existing route by its name.
|
|
- [`getRoutes()`](https://router.vuejs.org/api/interfaces/Router.html#getRoutes): Get a full list of all the route records.
|
|
- [`hasRoute()`](https://router.vuejs.org/api/interfaces/Router.html#hasRoute): Checks if a route with a given name exists.
|
|
- [`resolve()`](https://router.vuejs.org/api/interfaces/Router.html#resolve): Returns the normalized version of a route location. Also includes an `href` property that includes any existing base.
|
|
|
|
```ts [Example]
|
|
const router = useRouter()
|
|
|
|
router.addRoute({ name: 'home', path: '/home', component: Home })
|
|
router.removeRoute('home')
|
|
router.getRoutes()
|
|
router.hasRoute('home')
|
|
router.resolve({ name: 'home' })
|
|
```
|
|
|
|
::note
|
|
`router.addRoute()` adds route details into an array of routes and it is useful while building [Nuxt plugins](/docs/guide/directory-structure/plugins) while `router.push()` on the other hand, triggers a new navigation immediately and it is useful in pages, Vue components and composable.

## Based on History API
|
|
|
|
- [`back()`](https://router.vuejs.org/api/interfaces/Router.html#back): Go back in history if possible, same as `router.go(-1)`.
|
|
- [`forward()`](https://router.vuejs.org/api/interfaces/Router.html#forward): Go forward in history if possible, same as `router.go(1)`.
|
|
- [`go()`](https://router.vuejs.org/api/interfaces/Router.html#go): Move forward or backward through the history without the hierarchical restrictions enforced in `router.back()` and `router.forward()`.
|
|
- [`push()`](https://router.vuejs.org/api/interfaces/Router.html#push): Programmatically navigate to a new URL by pushing an entry in the history stack. **It is recommended to use [`navigateTo`](/docs/api/utils/navigate-to) instead.**
|
|
- [`replace()`](https://router.vuejs.org/api/interfaces/Router.html#replace): Programmatically navigate to a new URL by replacing the current entry in the routes history stack. **It is recommended to use [`navigateTo`](/docs/api/utils/navigate-to) instead.**
|
|
|
|
```ts [Example]
|
|
const router = useRouter()
|
|
|
|
router.back()
|
|
router.forward()
|
|
router.go(3)
|
|
router.push({ path: "/home" })
|
|
router.replace({ hash: "#bio" })
|
|
```

## Navigation Guards
|
|
|
|
`useRouter` composable provides `afterEach`, `beforeEach` and `beforeResolve` helper methods that acts as navigation guards.
|
|
|
|
However, Nuxt has a concept of **route middleware** that simplifies the implementation of navigation guards and provides a better developer experience.

|
|
|
|
## Promise and Error Handling
|
|
|
|
- [`isReady()`](https://router.vuejs.org/api/interfaces/Router.html#isReady): Returns a Promise that resolves when the router has completed the initial navigation.
|
|
- [`onError`](https://router.vuejs.org/api/interfaces/Router.html#onError): Adds an error handler that is called every time a non caught error happens during navigation.

|
## Universal Router Instance
|
|
|
|
If you do not have a `pages/` folder, then [`useRouter`](/docs/api/composables/use-router) will return a universal router instance with similar helper methods, but be aware that not all features may be supported or behave in exactly the same way as with `vue-router`.
