Laravel + Vue or Jsut VueCli App for a website

Hi awesome people

i want to build an E-commerce Website, i'm confused which method to follow for best and efficient performance and scalability of the website

1-> Should i create a Laravel API(only api no views) separately so that the mobile apps and Vue or Angular apps can build on top of it

2-> Should i use Vue with laravel for website and an API for mobile apps

i'm confused between whether to use Vue with laravel or Build a separate Vue apps using laravel api

and if i choose the 1 method how do i handle RESTfull shopping cart with the user session and all

i need some opinion from you guys for best practice

thank you
