jsLingui VS React Intl

https://lingui.dev/ by far.

We choose lingui.

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.

We use LinguiJS on a medium sized project and find it to work really well. It’s small, supports multiple message formats, has CLI scripts for extracting message ids from source, JS apis, Babel macros, React components and hooks, webpack and snowpack plugins, good pluralization support and much more.

I really like https://lingui.js.org/. It will create the .json or .po for you. And the component is just 😍.

I'm a fan of Lingui. I use it for instant.bible.

Lingui JS

lingui

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.
