What does the proposed API of configuration look like?

const MomentLocalesPlugin = require('moment-locales-webpack-plugin');

module.exports = {
    plugins: [
        // To strip all locales except “en”
        new MomentLocalesPlugin(),
 
        // Or: To strip all locales except “en”, “es-us” and “ru”
        // (“en” is built into Moment and can’t be removed)
        new MomentLocalesPlugin({
            localesToKeep: ['es-us', 'ru'],
        }),
    ],
};
