React Intl VS rails-i18n

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.

Note that if you are using rails-i18n, configuration is automatically available for many locales.

And this example of translation for Rails defaults: https://github.com/svenfuchs/rails-i18n/blob/master/rails/locale/en.yml

Also, download ja.yml from rails-i18n and place it in config/locales.

Everything else is set up like site/welcome, but here, we introduce pluralization for countable things. I18n is able to select the appropriate translation based on the variable passed to it. If you see that pluralization is not working well for your locale, it's a good idea to enhance your Rails app with the rails-i18n gem.

rails-i18n

No. That does not contain time only no date i cannot use that without also geting date output also: https://github.com/svenfuchs/rails-i18n/blob/62ffdacdf52e2895715c9d708118bd5ffc320f6a/rails/locale/es-ES.yml. See? This is why I pose question in this reddit.

The origin of this format start Ruby. The i18n-js format is a direct export of translations defined by Ruby on Rails. To export the translations, a Ruby gem can be used, that's completely disconnected from Rails and that can be used for the solely purpose of exporting the translations, even if your project is written in a different language. For JavaScript there's a companion JavaScript package. It comes bundled with all base translations made available by rails-i18n. Base translations allow formatting date, numbers, and sentence connectors, among other things.

The translations are accquired from rails-i18n project -- which is one of the first modules that does things like this.

The Rails Locale Data Repository seems to be the only comprehensive collection of formats but unfortunately I have not seen a single date/time format it uses that is an actual date time format used in the given locale.

The cherry on top was that Comfy gem depended on rails-i18n, which overwrote date I18n translations coming from russian gem, breaking translations on some of the pages. Surely enough, this resulted in another hour or so of debugging and fixing.
