Replatforming a Commerce Layer Frontend Without Touching the Backend
Teams on Commerce Layer often have a backend they are happy with and a frontend that has become the bottleneck: slow for marketing, behind on Core Web Vitals, or costly to maintain. Because Commerce Layer is headless, you can renew the frontend in phases on the REST and GraphQL API while the backend stays exactly as it is.
Why phased beats big-bang
A full frontend rebuild is a large, risky program. The REST and GraphQL API already decouples frontend from backend, so you can move route groups one at a time and validate each against the live API before the next.
Phased replatforming on the REST and GraphQL API
- Phase 1: stand up the new Laioutr frontend against the REST and GraphQL API for a contained scope, for example content and landing pages
- Phase 2: migrate category and product pages, validating API responses against the live catalog
- Phase 3: move cart and checkout, the highest-risk flows, with parallel running and measurement
- Phase 4: cut over remaining routes and retire the old frontend
At every phase the Commerce Layer backend stays untouched. You change how data is rendered, not where it lives.
The rollback plan matters
Each phase has a defined scope and a rollback path: routes can point back to the previous frontend if a phase regresses. Performance and accessibility are validated per phase.
What you gain
- Marketing autonomy through a visual page builder, no engineering ticket per banner
- Lighthouse 100 target and Core Web Vitals out of the box
- WCAG 3.0 and BFSG handled at the platform level
- Backend optionality preserved
FAQ
Can we run Laioutr alongside our current frontend?
Yes. During transition both consume the same REST and GraphQL API, so you can migrate gradually.
Is the Commerce Layer backend modified?
No. Replatforming happens at the frontend layer on the API. Backend and data stay in place. See the Commerce Layer pillar page or book a scoping call.
