Firstly, it looks like the way you are doing mixins is not the right way in Vue3. Your syntax looks like it would work with Vue2, but not Vue3. See below for an example:

createApp({
  extends: App,
  mixins: [your mixins here..],
}).mount('#app')

I'd recommend just importing this library where it's required.. such as a Checkout component if it's only needed in certain places.
