Using twig as template engine

Since yii2-simplechat lets you choose the template engine you prefer, it does not include twig as required dependency. So if you really want to use twig as the template engine, you should include manually twig packages in your project's composer.json.

{
    "require": {
        "yiisoft/yii2-twig": "> 2.0.4",
        "bower-asset/twig.js" : "0.8.4@stable"
    },
}
