Oofta i could go on for a while,
I want to be able to build my own frontend in nextjs. A headless approach. I understand that it is already doable, but i would like to avoid the checkout, payment processing, shipping, discounts, taxes headache & utilise all the wonderful apis wix offer.
The nice thing with the storefront api, is that they handle the whole checkout process + shipping/taxes, leaving the frontend totally customizable, less bloaty

If we could get a little create endpoint there, that could be nice
Also if wix paper performance vs perceived performance (great on desktop), none of this would be necessary!
I’m sure a lot of things are in the works. Bottle in the sea.
