use-intl

use-intl 🌐

A minimal, but complete solution for managing translations, date, time and number formatting in React apps.

Features

• 🌟 I18n is an essential part of the user experience, therefore this library doesn't compromise on flexibility and never leaves you behind when you need to fine tune a translation. Messages use the proven ICU syntax which covers interpolation, plurals, ordinal pluralization, label selection based on enums and rich text.
• 📅 Built-in date, time and number formatting provides all the necessary parts you need for localisation. You can use global formats for a consistent look & feel of your app and integrate them with translations.
• 💡 A hooks-only API ensures that you can use the same API for children as well as for attributes which expect strings.
• ⚔️ Based on battle-tested building blocks from Format.JS (used by react-intl), this library is a thin wrapper around high-quality, lower-level APIs for i18n.

What does it look like?

This library is based on the premise that messages can be grouped by namespaces (typically a component name).

// en.json
{
  "LatestFollower": {
    "latestFollower": "{username} started following you",
    "followBack": "Follow back"
  }
}

// LatestFollower.js
function LatestFollower({user}) {
  const t = useTranslations('LatestFollower');

  return (
    <>
      <Text>{t('latestFollower', {username: user.name})}</Text>
      <IconButton aria-label={t('followBack')} icon={<FollowIcon />} />
    </>
  );
}

Installation

1. Install use-intl in your project
2. Add the provider

import {IntlProvider} from 'use-intl';

// You can get the messages from anywhere you like. You can also fetch
// them from within a component and then render the provider along with
// your app once you have the messages.
const messages = {
  App: {
    hello: 'Hello'
  }
};

ReactDOM.render(
  <IntlProvider messages={messages} locale="en">
    <App />
  </IntlProvider>
)

1. Based on the features you need and the browsers you support, you might have to provide polyfills.
2. Use translations in your components!
