Similar Npm Packages to react-i18next

react-i18next is a powerful internationalization (i18n) library for React applications. It is built on top of the popular i18next framework and provides a seamless way to implement multilingual support in React apps. With react-i18next, developers can easily manage translations, handle language switching, and integrate with React's component lifecycle. This library is particularly useful for applications that need to cater to a global audience, ensuring that users can interact with the app in their preferred language.

While react-i18next is a robust solution for internationalization, there are other libraries that also provide i18n capabilities. Here are a couple of alternatives:

  • i18next is the core internationalization framework that serves as the foundation for react-i18next. It is a versatile and powerful library that can be used with various JavaScript frameworks, not just React. i18next provides a comprehensive set of features for managing translations, including support for pluralization, context, and interpolation. If you are looking for a more framework-agnostic solution or need to implement i18n in a non-React application, i18next is an excellent choice.
  • react-intl is another popular library for internationalization in React applications. It is part of the FormatJS project and provides a set of React components and an API for formatting dates, numbers, and strings in a localized manner. React-intl is particularly useful for applications that require advanced formatting capabilities alongside translation. If your application needs to handle complex formatting scenarios in addition to basic translations, react-intl is a strong alternative to consider.

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.
