3.0 preview (see announcement)

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 Next.js 13 and the App Router has arrived →

import {useTranslations} from 'next-intl';import OnlineStatus from './OnlineStatus'; function UserDetails({user}) {  const t = useTranslations('UserDetails');   return (    <section>      <h2>{t('title')}</h2>      <p>{t('followers', {count: user.followers.length})}</p>      <OnlineStatus lastSeen={user.lastSeen} />    </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.

{  "UserDetails": {    "title": "User details",    "followers": "{count, plural, ↵                    =0 {No followers yet} ↵                    =1 {One follower} ↵                    other {# followers} ↵                  }",

ICU message syntax

Localize your messages with interpolation, plurals, ordinal pluralization, 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 UserDetails({user}) {  const t = useTranslations('UserDetails');   return (    <section>      <h2>{t(''
title
followers)}</h2>    </section>  );}

Type-safe

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

const t = useTranslations('UserDetails'); 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.

“We were initially worried that adding support for multiple languages to our app would add overwhelming complexity, but next-intl genuinely made the process so much smoother than we expected.”
