👍 thanks man, that saved me at least a few hours.

Hi, we are changing our front end to use only React as a Single Page Application inside the Rails app with Webpacker.

I wonder if i can use i18n-js to translate html generated from React.
With this piece of code, i am able to receive translations in React code but the js import of I18n only gives defaultLocale, not the currentLocale.
I can write code to get currentLocal from localStorage or cookies easily but is there a way to handle url without rewriting the detection functions in js ?

Anyone managed to combine this with jest tests?

Thanks for the Hint @kfiltschew! So you can just use:

import I18n from "i18n-js"
I18n.translations = <%= I18n::JS.filtered_translations.to_json %>;
I18n.locale = "<%= I18n.locale %>";
export default I18n

in i18n-js/index.js.erb

@m-andreas Nope you can't
