Next.js

Before moving forward, we recommend you to read Routing Introduction first.

useRouter

If you want to access the object inside any function component in your app, you can use the hook, take a look at the following example:

is a React Hook, meaning it cannot be used with classes. You can either use withRouter or wrap your class in a function component.

object

The following is the definition of the object returned by both and :

  • : - Current route. That is the path of the page in , the configured or is not included.
  • : - The query string parsed to an object. It will be an empty object during prerendering if the page doesn't have data fetching requirements. Defaults to
  • : - The path (including the query) shown in the browser without the configured or .
  • : - Whether the current page is in fallback mode.
  • : - The active basePath (if enabled).
  • : - The active locale (if enabled).
  • : - All supported locales (if enabled).
  • : - The current default locale (if enabled).
  • : - Any configured domain locales.
  • : - Whether the router fields are updated client-side and ready for use. Should only be used inside of methods and not for conditionally rendering on the server.
  • : - Whether the application is currently in preview mode.

Additionally, the following methods are also included inside :

router.push

Handles client-side transitions, this method is useful for cases where is not enough.

  • - The URL to navigate to
  • - Optional decorator for the path that will be shown in the browser URL bar. Before Next.js 9.5.3 this was used for dynamic routes, check our previous docs to see how it worked. Note: when this path differs from the one provided in the previous / behavior is used as shown in the previous docs
  • - Optional object with the following configuration options:
    • - Optional boolean, controls scrolling to the top of the page after navigation. Defaults to
    • : Update the path of the current page without rerunning , or . Defaults to
    • - Optional string, indicates locale of the new page

You don't need to use for external URLs. window.location is better suited for those cases.

Usage

Navigating to , which is a predefined route:

Navigating , which is a dynamic route:

Note: When navigating to the same page in Next.js, the page's state will not be reset by default, as the top-level React component is the same. You can manually ensure the state is updated using .

Redirecting the user to , useful for pages behind authentication:

With URL object

You can use a URL object in the same way you can use it for . Works for both the and parameters:

router.replace

Similar to the prop in , will prevent adding a new URL entry into the stack.

  • The API for is exactly the same as the API for .

Usage

Take a look at the following example:

router.prefetch

Prefetch pages for faster client-side transitions. This method is only useful for navigations without , as takes care of prefetching pages automatically.

This is a production only feature. Next.js doesn't prefetch pages on development.

  • - The URL to prefetch, including explicit routes (e.g. ) and dynamic routes (e.g. )
  • - Optional decorator for . Before Next.js 9.5.3 this was used to prefetch dynamic routes, check our previous docs to see how it worked

Usage

Let's say you have a login page, and after a login, you redirect the user to the dashboard. For that case, we can prefetch the dashboard to make a faster transition, like in the following example:

router.beforePopState

In some cases (for example, if using a Custom Server), you may wish to listen to popstate and do something before the router acts on it.

  • - The function to run on incoming events. The function receives the state of the event as an object with the following props:
    • : - the route for the new state. This is usually the name of a
    • : - the url that will be shown in the browser
    • : - Additional options sent by router.push

If returns , the Next.js router will not handle , and you'll be responsible for handling it in that case. See Disabling file-system routing.

Usage

You could use to manipulate the request, or force a SSR refresh, as in the following example:

router.back

Navigate back in history. Equivalent to clicking the browser’s back button. It executes .

Usage

router.reload

Reload the current URL. Equivalent to clicking the browser’s refresh button. It executes .

Usage

router.events

You can listen to different events happening inside the Next.js Router. Here's a list of supported events:

  • - Fires when a route starts to change
  • - Fires when a route changed completely
  • - Fires when there's an error when changing routes, or a route load is cancelled
    • - Indicates if the navigation was cancelled
  • - Fires before changing the browser's history
  • - Fires when the hash will change but not the page
  • - Fires when the hash has changed but not the page

Note: Here is the URL shown in the browser, including the .

Usage

For example, to listen to the router event , open or create and subscribe to the event, like so:

We use a Custom App () for this example to subscribe to the event because it's not unmounted on page navigations, but you can subscribe to router events on any component in your application.

Router events should be registered when a component mounts (useEffect or componentDidMount / componentWillUnmount) or imperatively when an event happens.

If a route load is cancelled (for example, by clicking two links rapidly in succession), will fire. And the passed will contain a property set to , as in the following example:

withRouter

If is not the best fit for you, can also add the same object to any component.

Usage

TypeScript

To use class components with , the component needs to accept a router prop:
