How do I manage assets in Yii2?

Question

For example, I created a new page, and I\'d like to use, for example, backbone.js, custom css file and some collection of images. Where should I declare all this stuff in Yii2?

Answer 1

It took me a while to figure it out, but below is the relevant part of the Yii2 source code

if ($this->sourcePath !== null && !isset($this->basePath, $this->baseUrl)) {
    list ($this->basePath, $this->baseUrl) = $am->publish($this->sourcePath, $this->publishOptions);
}

So Yii2 will publish assets only if $sourcePath is set, and $basePath and $baseUrl are not set(!). The latter tripped me up, and it looks like the same goes for you.

So I have this AppAsset, which duly publishes

use yii\web\AssetBundle;


class AppAsset extends AssetBundle
{
public $sourcePath = '@app/assets/app';

public $css = [
    'css/openbook.css',
    'fontello/css/fontello.css',
    'fontello/css/animation.css'
];
public $js = [
    'js/plug.openbook.js',
    'js/plug.interpret.js',
    'js/plug.drop.message.js'
];
public $depends = [
   // 'yii\web\YiiAsset', 
   // 'yii\bootstrap\BootstrapAsset',
];
} 

Of course, I have in the main layout

use frontend\assets\AppAsset;
...
AppAsset::register($this);
