react-i18next VS React Intl

In a recent project I've been using react-i18next so I'll use its syntax for the examples, but pretty much every library works similarly.

react-i18next

i18next - You can find documentation and resources for using i18next at react.i18next.com. i18next is a popular internationalization framework for JavaScript, including React. It provides a comprehensive solution for handling translations, formatting, and more.

So far, we’ve been using a utility createLocalizedString to create and use the LocalizedString type. This utility is only really practical in unit tests. For real applications, we’ll want to use a translation function from react-i18next or next-i18next to do the heavy lifting. Then we just wrap the translation functions that are provided in order to use our type:

If you are talking about handling translations for your application, take a look at https://react.i18next.com/

I will be supporting Korean as a part of the beta. I have to look deeper into https://react.i18next.com/ in order to understand what it provides. My goal is for engineers to be able to click a single button and have localizations always up to date in their codebase, not delaying shipping a new version or having to even think about it.

With the new react-i18next version, when loading multiple namespaces, t function will infer and accept the keys for the first namespace. So this pattern is now accepted:

react-i18next

In this article I will show you how to translate your React app with React-i18next and give a few examples that you may find useful!

You can use a third-party library, which is a bunch of code that someone else wrote for you. Many awesome third-party libraries can format numbers with commas in JavaScript. For example, you can try Numeral.js, Accounting.js, or Format.js.

react-intl

Looks like react has an npm package for internationalizing too. https://www.npmjs.com/package/react-intl

Format.JS

React i18n: Documentation: https://formatjs.io/docs/react-intl/ Source Code: https://github.com/formatjs/formatjs

de { key1 { "Deutsche Sprache " "schwere Sprache" } key2 { "Düsseldorf" }} I've found this library http://formatjs.io/react/. http://formatjs.io/ supports ICU, however I can't find any good example how to wire my language files with my app.

As we mentioned earlier, the Next.js works well with existing i18n libraries (react-intl, lingui, next-intl, and similar). In this tutorial, we will use the react-intl.

The second format is the ICU Message Format. There are multiple JavaScript modules implementing the ICU message syntax. One of the most used is intl-messageformat by Format.js. It is used behind the scenes also in react-intl.
