Replatforming a Vendure Frontend Without Touching the Backend

Teams on Vendure often have a backend they are happy with, plugins, custom entities, B2B workflows, and a frontend that has become the bottleneck: slow to change for marketing, behind on Core Web Vitals, or expensive to maintain. Because Vendure is headless, you can renew the frontend in phases on the Shop API while the backend stays exactly as it is.

Why phased beats big-bang

A full frontend rebuild is a large, risky program. But Vendure's GraphQL Shop API already decouples frontend from backend, so you do not have to do it all at once. You can move route groups one at a time and validate each against the live Shop API before the next.

Phased replatforming on the Shop API

• Phase 1: stand up the new Laioutr frontend against the Shop API for a contained scope, for example content and landing pages
• Phase 2: migrate collection and product pages, validating Shop API queries 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 Vendure backend stays untouched. Your plugins, custom entities and workflows keep running. 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. Replatforming becomes a controlled sequence of reversible steps rather than a single cutover. 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, since the frontend is not re-coupled to backend internals

Realistic timeline

A mid-sized Vendure storefront with clear branding and no exotic custom logic typically goes from kickoff to first live phase in weeks, with full cutover over a few phases. Heavy B2B or multi-channel setups are scoped per phase.

FAQ

Can we run Laioutr alongside our current storefront?

Yes. During transition both consume the same GraphQL Shop API, so you can migrate route groups gradually.

Is the Vendure backend or our plugins modified?

No. Replatforming happens at the frontend layer on the Shop API. Backend code, plugins and data stay in place. Book a migration scoping call.

How is risk controlled?

Through phasing and rollback. Each phase is reversible, and high-risk flows like checkout run in parallel before cutover.
