Condition for Assets in Yii2?

Question

Yii

Good day.
Is there a variable, Yii::$app->language
how can I include scripts in assets based on what this variable returns? Without creating its own asset for each language,
that is, for "ru" to connect the script

'theme/assets/global/plugins/date/locales/dater.ru.min.js'

and for "en"

'theme/assets/global/plugins/date/locales/dater.en.min.js'

Answer 1

Use AssetBundle and init() method in it like this:

<?php

namespace app\assets;

use yii\web\AssetBundle;

class AppAsset extends AssetBundle
{
    public function init()
    {
        $format = 'theme/assets/global/plugins/date/locales/dater.%s.min.js';
        $this->js[] = sprintf($format, \Yii::$app->language);
    }
}

Answer 2

'theme/assets/global/plugins/date/locales/dater.' . Yii::$app->language . '.min.js'

?
