Internationalization for Next.js that gets out of your way.

Support multiple languages, with your app code becoming simpler instead of more complex.

📣 Support for Server Components has arrived →
import {useTranslations} from 'next-intl'; export default function UserProfile({user}) {  const t = useTranslations('UserProfile');   return (    <section>      <h1>{t('title', {firstName: user.firstName})}</h1>      <p>{t('membership', {memberSince: user.memberSince})}</p>      <p>{t('followers', {count: user.numFollowers})}</p>    </section>  );}

Batteries included, minimalistic API

Internationalization (i18n) is an essential part of the user experience, therefore next‑intl gives you everything you need to get language nuances right in your Next.js apps.
{  "UserProfile": {    "title": "{firstName}'s profile",    "followers": "{count, plural,                    =0 {No followers yet}                    =1 {One follower}                    other {# followers}                  }"

ICU message syntax

Localize your messages with interpolation, cardinal & ordinal plurals, enum-based label selection and rich text.

// "Feb 28, 2023"format.dateTime(lastSeen, 'medium'); // "2 hours ago"format.relativeTime(lastSeen); // "$1,499.90"format.number(1499.9, {style: 'currency', currency: 'USD'});

Dates, times & numbers

Apply appropriate formatting without worrying about server/client differences like time zones.

function UserProfile({user}) {  const t = useTranslations('UserProfile');   return (    <section>      <h1>{t(''
title
followers
)}</h1>
</section> );}

Type-safe

Speed up development with autocompletion for message keys and catch typos early with compile-time checks.

const t = useTranslations('UserProfile'); t('followers', {count: user.followers.length}); // stringt.rich('bio', {b: (chunks) => <b>{chunks}</b>}); // ReactNode const format = useFormatter();const timeZone = useTimeZone();const locale = useLocale();const now = useNow();

Hooks-only API

Learn a single API that can be used across your code base to turn translations into plain strings or rich text.
