Nested

nestjs-i18n supports nested translations.

You can make nested translations by using this function.

$t(auth.PAGE_HOME.TITLE)

To pass along arguments use

{
  "WELCOME": "$t(auth.WELCOME, {{ \"username\": \"{username}\" }})"
}

Here is an example of how this looks in your translation files

src/i18n/en/test.json

{
    "HELLO": "World",
    "WELCOME": "Hello {username}",
    "PAGE_HOME": {
        "TITLE": "Home to this $t(auth.HELLO)",
        "SUBTITLE": "$t(auth.WELCOME, {{ \"username\": \"{username}\" }}) this is the home page"
    }
}

i18n.t('test.PAGE_HOME.SUBTITLE', {args: { username: 'Toon' } })
// => Hello Toon, this is the home page

tip

The formatter is applied before doing nested translations. This way you can pass on arguments to your nested translations! 🎉
