Why is yii2 not reading jquery file?

Question

Yii

public $js = [
        'js/jquery3-3-1.min.js',
        'js/style.js',
    ];

Here's the thing.. style.js works but jquery only works when connected directly via script, what could be the reason?

Answer 1

If your AppAsset depends on YiiAsset, then keep in mind that YiiAsset already depends on the framework's built-in JqueryAsset. This way you include two jquery.
You can explicitly specify in the configuration that your jquery should be used instead of JqueryAsset :

'assetManager' => [
            'bundles' => [
                'yii\web\JqueryAsset' => [
                    'sourcePath' => '@frontend/assets',
                    'js' => [
                        'js/my-jquery.js',
                    ],
                ],
            ],
        ],

yii doesn't have to read anything, it includes files. So you need to check whether you have connected it and if not, check whether it is there from where you connect it.
