Where to define different asset files for dev/prod mode? - Yii2 - php

Question

I would like to use different js files for development and production mode in Yii2. The development mode has lot of files unminified, although the production would have a single file.
The development asset goes like this:
namespace frontend\assets;
use yii\web\AssetBundle;
class AppAsset extends AssetBundle {
public $basePath = '#webroot';
public $baseUrl = '#web';
public $css = [
'css/main.css',
];
public $js = [
'js/app/_variables.js',
'js/app.js',
'js/app/_api_conn.js',
'js/app/_docCookies.js',
'js/app/ ..... .js',
];
public $depends = [
'yii\bootstrap\BootstrapPluginAsset',
];
}
And I would like to have this particular bundle like this in production mode, already merged and minified locally:
namespace frontend\assets;
use yii\web\AssetBundle;
class AppAsset extends AssetBundle {
public $basePath = '#webroot';
public $baseUrl = '#web';
public $css = [
'css/main.css',
];
public $js = [
'js/wfapp_all_min.js',
];
public $depends = [
'yii\bootstrap\BootstrapPluginAsset',
];
}
As the Yii2 documentation explains there is a single method to do this, but I can't find out, where to add it (the example is for jquery asset, but seems right method for my case as well):
'yii\web\JqueryAsset' => [
'js' => [
YII_ENV_DEV ? 'jquery.js' : 'jquery.min.js'
]
],
So what is the proper way to implement this? Thanks in advance!

Answer 1

In case of different amount of files for debug and production servers, you can set them during initialization in init() method:
public function init()
{
$this->js = !YII_DEBUG ? ['js/wfapp_all_min.js'] : [
'js/app/_variables.js',
'js/app.js',
'js/app/_api_conn.js',
'js/app/_docCookies.js',
'js/app/ ..... .js',
];
parent::init();
}
Don't forget to call the parent implementation at the end.
