Babel Plugin

If you use different bundles for different languages, you can remove unused locales with the babel plugin to reduce the size of your production bundle.

Usage

In your .babelrc:

{
    "presets": ["@babel/preset-env"],
    "plugins": [
        [
            "localang-i18n-js/babel/remove-unused-languages.js",
            {
                "lang": "en" // Language to keep in i18n-files, e.g., "en" for English
            }
        ]
    ]
}
