What's Internationalization Libraries for Frontend Frameworks?

Internationalization (i18n) libraries are essential tools for enabling applications to support multiple languages and cultural formats. They provide developers with the means to manage translations, format dates and numbers according to locale, and facilitate a seamless user experience across different languages. These libraries are crucial for reaching a global audience and ensuring that applications are accessible and user-friendly for diverse populations. Each library is tailored to specific frameworks, offering unique features and integration methods that align with the architecture and design principles of Angular, React, and Vue.js.

What will my code look like?

Before: Your react code would have looked something like:

...
<div>Just simple content</div>
<div>
  Hello <strong title="this is your name">{name}</strong>, you have {count} unread message(s). <Link to="/msgs">Go to messages</Link>.
</div>
...

After: With the trans component just change it to:

...
<div>{t('simpleContent')}</div>
<Trans i18nKey="userMessagesUnread" count={count}>
  Hello <strong title={t('nameTitle')}>{{name}}</strong>, you have {{count}} unread message. <Link to="/msgs">Go to messages</Link>.
</Trans>
...

📖 What others say

Why i18next?

  • Simplicity: no need to change your webpack configuration or add additional babel transpilers, just use create-react-app and go.
  • Production ready we know there are more needs for production than just doing i18n on the clientside, so we offer wider support on serverside too (nodejs, php, ruby, .net, ...). Learn once - translate everywhere.
  • Beyond i18n comes with locize bridging the gap between development and translations - covering the whole translation process.
