Yii2 How to enable default assets only in certain modules - yii2

Question

I am using basic yii2 app, I have disabled the boostrap css and js in web.php config but i want to enable it inside the module called admin.
I tried adding like this, for component section in config.php under admin module folder, but no luck!
'assetManager' => [
'bundles' => [
'yii\bootstrap\BootstrapPluginAsset' => [
'js'=> ['js/boostrap.js']
],
'yii\bootstrap\BootstrapAsset' => [
'css' => ['css/boostrap.min.css']
]
],
],
How can i achieve this?

Answer 1

In your module's init() method, you can override an exist asset bundle like below:
public function init() {
\Yii::$app->assetManager->bundles['yii\bootstrap\BootstrapAsset'] = [
'css' => ['css/bootstrap_NEW.css']
];
parent::init();
}
In above example, we override yii\bootstrap\BootstrapAsset CSS file in our module. So, in this module, it uses bootstrap_NEW.css instead of its default.
Please note that, you can do this in application globally, not specially in module's init() method. It was just a suggestion to solve this specific case.

You should use asset bundles to handle this, no need to modify assetManager.
To disable Bootstrap, simply remove it from $depends in AppAsset :
public $depends = [
'yii\web\YiiAsset',
];
Create a ModuleAsset class in your module :
class ModuleAsset extends \yii\web\AssetBundle
{
public $depends = [
'yii\bootstrap\BootstrapAsset',
];
}
Make sure to register it in your module's views (you could use a custom layout) :
ModuleAsset::register($this);
