Headless means that you're using e-commerce platform only via API and build your front-end in whatever tech you want (next, nuxt, Remix, etc). It's different from a traditional approach when e-commerce platform handles front-end (HTML templates rendering). In Shopify can do both.

Funny that headless is now considered "traditional," when that was considered standard for a decade and a half. Relying on the platform was considered amateur.

Well, those who now use shopify used to use prestashop, magento or shopworn before. Not sure if all of those stores were run by amateurs.

"Traditional" is just another way to say "what was once the norm", so your comment is a bit pleonastic. Is relying on the platform no longer considered amateur? If yes, call me old fashioned, because I've never liked those platforms...

Thank you!
