Built-In Bundles In Yii2

When using Yii 1 I kept a list of packages in my app for reference so I would correctly name any that I re-defined, avoid name conflicts with ones I define for myself, & have correct names for dependancies.

My starting point was the file at <path_to>/framework/web/js/packages.php.

Can anyone tell me where to list of built-in bundles in Yii2?

Either in the code (I’m using the advanced template) like I did with Yii 1, or docs, or elsewhere.

Cheers, Pedro :)
