Multi-Store Product Recommendation Infrastructure
The backend behind a guided eyewear recommendation running on two storefronts at once: one recommendation service, one catalogue reader, and per-store configuration rather than two forks.
Production RecordedClient ContributionCloud & Infrastructure
Overview
Two optical storefronts — Ópticas LUX and Más Visión México — share a catalogue model and a recommendation experience but not a theme, a domain or a product set. The infrastructure is built around that: an Express service holding the recommendation logic, a React client embedded into each storefront, catalogue reads through the Shopify Storefront API, and per-store configuration passed in rather than compiled in. Historically it ran on Heroku; the newer architecture work is on Google Cloud.
What EcomLabs did
- Built the recommendation service in Node.js and Express, with per-store configuration as an input rather than a fork.
- Built the embedded client in React on a Vite toolchain, so it loads inside a Shopify theme without owning the page.
- Read catalogue data through the Shopify Storefront API so each store keeps its own products and availability.
- Instrumented the experience so the steps people abandon are visible.
Capabilities
- One recommendation service serving more than one storefront.
- Per-store configuration instead of a forked codebase per brand.
- Catalogue reads through the Shopify Storefront API.
- An embedded React client that lives inside a Shopify theme.
- Step-level analytics on the guided flow.
