I wrote a plugin that goes through all my locale files and combine them into a single json file per locale, where each key follows the directory structure.
scenes/Home/locales/en.json has some locales:
The plugin generates a file per locale,
/public/locales/en.json that I download when the app boots, which looks like this:
Then using React-Intl, I inject the content to the
IntlProvider and use it that way:
<FormattedMessage id="scenes.Home.menuLabel" />
