Fully functional general e-commerce WebApp

Working demo: https://emaria.vercel.app/

Techs used: Vue3, Nuxt3, Pinia, Supabase, Sanity, Formkit, VueUse, Aos.

[Vue3 & Nuxt3] as building blocks.
[Pinia] to maintain cart state on client side, to share fetched products & some globally needed boolean values across components.
[Supabase] to save cart/user data, and to build auth/oauth.
[sanity] as a headless cms to build and maintain products-api by using a user-friendly gui which sanity provides us.
[Formkit] to build easily maintainable forms.
[VueUse-IntersectionObserver] to implement infinite scroll.
[Aos] to build scroll reveal animations.
[Prisma] to manage database with ease.

The Sanity Headless Cms:

Products api can be maintained from a no-code, user-friendly headless frustructure by the shop owner. A view from the ui of the Sanity CMS:

Shop UI:

After choosing an item from shop, page will lead the user to that item's page:

If the user is logged in and wants to add an item to the cart, it will be added to his/her cart, and all of this will be happening in an SQL database.
The cart UI can be seen at the bottom:

What would i do next?

I would handle buyouts with Stripe api or using similar on Nuxt server routes if it was a real world e-commerce.
Could make "add to fav" button functional.
Could add product variant categories (color, size) to the Sanity cms.
