Next.js 13 internationalized navigation
next-intl
provides drop-in replacements for common Next.js navigation APIs that automatically handle the user locale behind the scenes.
Strategies
There are two strategies that you can use based on your needs:
Each strategy will provide you with corresponding navigation APIs that you can use in your components. Typically, you'll provide these APIs in a central module that you can easily reference (e.g. ./navigation.ts
).
Strategy 1: Shared pathnames
The simplest case is when your app uses the same pathnames, regardless of the locale, e.g.:
/en/about
/en-GB/about
In this example, the path segment about
remains the same, regardless of the user's locale. This is the simplest case, because the routes you define in Next.js will map directly to the URLs that a user can request.
To create navigation APIs for this use case, use the createSharedPathnamesNavigation
function:
import {createSharedPathnamesNavigation} from 'next-intl/navigation';
export const {Link, redirect, usePathname, useRouter} =
createSharedPathnamesNavigation({
locales: ['en', 'en-GB'],
pathnames: {
'/': '/',
'/about': {
en: '/about',
de: '/ueber-uns'
}
}
});
The pathnames
argument is identical to the configuration that you pass to the middleware for localizing pathnames. Because of this, you might want to share it along with the locales
from a shared file like i18n.ts
:
import {Pathnames} from 'next-intl/navigation';
export const locales = ['en', 'de'] as const;
export const pathnames: Pathnames<typeof locales> = {
'/': '/',
'/about': {
en: '/about',
de: '/ueber-uns'
}
} as const;
Have a look at the App Router example to explore a working implementation of localized pathnames.
Strategy 2: Localized pathnames
If you've configured the middleware to use localized pathnames, you can use the createLocalizedPathnamesNavigation
function to create corresponding navigation APIs:
're using the middleware configuration localized pathnames in the
Many apps choose to localize pathnames, especially when search engine optimization is relevant:
import {createLocalizedPathnamesNavigation} from 'next-intl/navigation';
export const {Link, redirect, usePathname, useRouter} =
createLocalizedPathnamesNavigation({
locales: ['en', 'en-GB']
});
APIs
Link
This component wraps next/link
(opens in a new tab) and automatically prefixes the href
with the current locale as necessary. If the default locale is matched, the href
remains unchanged and no prefix is added.
import {Link} from '../navigation';
// When the user is on `/en`, the link will point to `/en/about`
<Link href="/about">About</Link>
// You can override the `locale` to switch to another language
<Link href="/" locale="de">Switch to German</Link>
// Dynamic params need to be interpolated into the pathname
<Link href="/users/12">Susan</Link>
Note that prefetch
will be turned off when linking to another locale to
avoid prematurely overwriting the locale cookie.
useRouter
If you need to navigate programmatically, e.g. in an event handler, next-intl
provides a convience API that wraps useRouter
from Next.js (opens in a new tab) and automatically applies the locale of the user.
'use client';
import {useRouter} from '../navigation';
const router = useRouter();
// When the user is on `/en`, the router will navigate to `/en/about`
router.push('/about');
// You can override the `locale` to switch to another language
router.replace('/about', {locale: 'de'});
// Dynamic params need to be interpolated into the pathname
router.push('/users/12', {locale: 'de'});
How can I change the locale for the current page?
By combining usePathname
with useRouter
, you can change the locale for the current page programmatically.
'use client';
import {usePathname, useRouter} from '../navigation';
const pathname = usePathname();
const router = useRouter();
router.replace(pathname, {locale: 'de'});
usePathname
To retrieve the pathname without a potential locale prefix, you can call usePathname
.
'use client';
import {usePathname} from '../navigation';
// When the user is on `/en`, this will be `/`
const pathname = usePathname();
redirect
This API is only available in the Server Components beta.
If you want to interrupt the render and redirect to another page, you can invoke the redirect
function. This wraps the redirect
function from Next.js (opens in a new tab) and automatically applies the current locale.
import {redirect} from '../navigation';
// When the user is on `/en/profile`, this will be `/en/login`
redirect('/login');
// Dynamic params need to be interpolated into the pathname
router.push('/users/12');
