A Hybrid Store: Shopify Checkout, Next.js Everything Else

The Challenge

Shopify themes are great for checkout and terrible for everything that ranks. Content structure, landing pages, and internal linking are all boxed in by what the theme allows. I wanted store-grade commerce with app-grade control over the rest of the site, without rebuilding the payment and inventory stack from scratch.

The Solution: Split the Site by Responsibility

The fix was to divide the domain by what each system is good at. Shopify keeps the money paths. A Next.js app on Vercel owns everything else and falls back to Shopify only for product and checkout routes.

• •**Shopify owns /products/* and checkout**, so cart, payments, and inventory stay on a proven backend
• •Next.js owns the rest of the site, giving full control of landing pages, collections, and the SEO surface
• •Fallback routing hands product URLs to Shopify and serves everything else from the app
• •200+ live collections generated and managed programmatically through the Shopify Admin API

Technical Architecture

The Next.js front end sits on Vercel and treats Shopify as a headless commerce layer for the routes that need it. Collections are built and updated through the Admin API rather than the theme editor, which means the catalog can be managed as data instead of hand-edited pages.

• •Next.js on Vercel serving the full site with a fallback to Shopify for /products/*
• •Shopify Admin API driving programmatic collection creation and updates
• •Headless-where-it-counts approach that keeps checkout on Shopify and the SEO surface in the app

Key Takeaways

You do not have to choose between a real commerce backend and a real content platform. Splitting the site by responsibility gets you both: Shopify handles the parts that are hard to build and risky to own, and the app handles the parts a theme would strangle. The result is live at the Wall Canvas Art storefront, where the Next.js layer owns the pages that do the ranking.
