If you have public assets like images, or scripts and stylesheets that you don't want to include in the bundle, place them in your application's public directory and then refer to them in your views using Laravel's asset() function.
If you're developing an extension, use the service provider's publishes method to publish your assets to the application's public directory:
To link to an external asset (e.g. Google Fonts or something else from a CDN), don't use the Stylesheet or Script extenders. Instead, use the DocumentHead extender to add a view to output in the <head> tag.
