The challenge
Where teams get stuck
The problems we're most often brought in to solve.
- 01
Themes miss performance targets
Liquid themes cannot reach the speed required on revenue-critical pages.
- 02
Data model has been outgrown
Catalogue or pricing logic no longer fits Shopify's standard data model.
- 03
Content and commerce are siloed
Editorial content and product data sit in separate, disconnected tools.
Overview
Composable & Headless Commerce at VulcanTech
Headless commerce separates the customer-facing storefront from the commerce engine behind it, connecting the two through APIs. VulcanTech builds composable storefronts with a Next.js front end and the commerce back end that fits your model, for organisations that need performance or flexibility a themed storefront cannot provide. An API layer connects storefront, commerce, inventory, content and payments, with performance budgets enforced on product and checkout pages.
Key deliverables
- Headless storefront in Next.js
- API layer for commerce, inventory and payments
- Headless CMS integration
- Performance budgets on revenue-critical pages
