#Replace only locale part
1 messages · Page 1 of 1 (latest)
To replace only the locale part of a URL in a React Next.js app, you can use the window.history.replaceState method to manipulate the URL without reloading the page. Below is an example of how you can achieve this using a dropdown to switch the language code in the locale part of the URL.
Here's a complete example based on the knowledge sources provided:
'use client'
import { usePathname } from 'next/navigation'
export function LocaleSwitcher() {
const pathname = usePathname()
function switchLocale(locale) {
// Extract the current locale part from the pathname
const parts = pathname.split('/')
if (parts.length > 1) {
// Assuming the locale is always the second part of the pathname
parts[1] = parts[1].replace(/^[a-z]{2}-[a-z]{2}$/, `${parts[1].split('-')[0]}-${locale}`)
}
const newPath = parts.join('/')
window.history.replaceState(null, '', newPath)
}
return (
<>
<select onChange={(e) => switchLocale(e.target.value)}>
<option value="en">English</option>
<option value="fr">French</option>
{/* Add more options as needed */}
</select>
</>
)
}
Explanation:
- Extract the Current Pathname: Use
usePathnamefromnext/navigationto get the current pathname. - Modify the Locale Part: Split the pathname by
/and replace the locale part (assumed to be the second part) with the new locale. - Update the URL: Use
window.history.replaceStateto update the URL without reloading the page.

This approach ensures that only the locale part of the URL is changed, and the rest of the URL remains intact.

@agile dagger kapa.ai is still learning and improving, please let us know how it did by reacting below
Hi @merry falcon please suugest something using app router next navigation..where i cant fincd locale from url..replace new locale to existing one
Let me check the knowledge base for you. One moment! :books:
To handle locale switching in a Next.js app using the App Router and Next.js navigation, you can use the usePathname and useRouter hooks from next/navigation. Here's how you can achieve this:
Step-by-Step Solution
- Extract the Current Pathname: Use
usePathnameto get the current pathname. - Modify the Locale Part: Split the pathname by
/and replace the locale part with the new locale. - Update the URL: Use
router.pushto navigate to the new URL with the updated locale.
Example Code
'use client'
import { usePathname, useRouter } from 'next/navigation'
export function LocaleSwitcher() {
const pathname = usePathname()
const router = useRouter()
function switchLocale(newLocale) {
// Extract the current locale part from the pathname
const parts = pathname.split('/')
if (parts.length > 1) {
// Assuming the locale is always the second part of the pathname
parts[1] = parts[1].replace(/^[a-z]{2}-[a-z]{2}$/, `${parts[1].split('-')[0]}-${newLocale}`)
}
const newPath = parts.join('/')
router.push(newPath)
}
return (
<>
<select onChange={(e) => switchLocale(e.target.value)}>
<option value="en">English</option>
<option value="fr">French</option>
{/* Add more options as needed */}
</select>
</>
)
}
Explanation:
- Extract the Current Pathname:
usePathnameis used to get the current URL pathname. - Modify the Locale Part: The pathname is split into parts, and the locale part (assumed to be the second part) is replaced with the new locale.
- Update the URL:
router.pushis used to navigate to the new URL with the updated locale.
