Magento Checkout Rebuilt in React Shows Performance Gains
Towering Media rebuilt the Magento (Adobe Commerce) checkout into a React-based product called React Checkout Pro, targeting Magento 2 and Hyvä stores. Benchmarks on a representative Luma checkout show large improvements in Core Web Vitals and bundle size (LCP 4.8s → 2.1s; INP 320ms → 95ms; CLS 0.18 → 0.04; JS transferred ~1.9MB → ~420KB; estimated TTI 6.2s → 2.8s). The architecture keeps Magento server-side business logic (taxes, shipping rates, payment tokenization) while moving the UI to a Vite-built React “island.” Real-world outcomes included an 11% mobile completion-rate increase for one client and reductions in support tickets and payment retries. The article outlines bundle changes, batching/debouncing API calls, Hyvä compatibility, tradeoffs (maintenance and extension compatibility), and measurement guidance before rewrites.
Measurable performance and conversion improvements for Magento/Hyvä merchants are relevant to e-commerce and MarTech teams, but this is a vendor-specific product and not an industry-wide platform change.

Key Takeaways & Evidence Grounding
- Towering Media rebuilt Magento checkout as a React product named React Checkout Pro for Magento 2 and Hyvä stores.
- Lab benchmark (representative Luma checkout) showed: LCP 4.8s → 2.1s; INP 320ms → 95ms; CLS 0.18 → 0.04; JS transferred ~1.9 MB → ~420 KB; estimated TTI 6.2s → 2.8s.
- One merchant reported an 11% increase in mobile checkout completion rate over 90 days after the React checkout deploy.
- Architecture retains Magento server-side responsibilities (quote totals, tax calculation, shipping rates, payment tokenization) and uses a React UI bundle (Vite) that calls Magento REST/GraphQL and payment providers (e.g., Stripe, Moneris).
- Implemented changes included replacing Knockout with a single React tree, Tailwind/minimal CSS, deferring non-critical scripts, and batching/debouncing address/shipping API calls; tradeoffs include added frontend build/maintenance and third-party extension incompatibility.

React Frontend Cuts Magento Checkout Drop-off 34%
Towering Media replaced a mid-market Magento 2 store's default Luma checkout with a React frontend (React Checkout Pro) while keeping Magento as the backend. Over a 90-day post-launch window the merchant saw checkout completion improve by 34% overall and mobile completion by 39%. Technical changes included consolidating UI fragments into a single application shell, debouncing and batching address-estimate network calls, code-splitting payment and deferring non-critical third-party scripts, and stabilizing layout to reduce CLS. The implementation kept Magento in charge of quote, shipping, tax, payment token exchange and order placement, while React handled state, validation, and optimistic rendering.
Magento Modernization Case Study: Migration, Performance, UX
This technical case study describes an enterprise Magento (Adobe Commerce) modernization project for a mid-market to enterprise merchant. The work focused on reducing migration risk and technical debt, improving scalability and frontend performance, and optimizing checkout UX. Key actions included migrating to the latest Adobe Commerce platform and Adobe Commerce Cloud hosting with autoscaling, implementing the Hyvä frontend to cut frontend assets, integrating Redis and Varnish for caching and session storage, using Magento’s GraphQL to decouple checkout, and refactoring legacy modules. The study reports confidentiality-limited results: faster page loads and checkout times, improved scalability under peak traffic, and stable SEO after migration. The article emphasizes planning, automation, SEO collaboration, continuous technical debt reduction, and cross-team coordination (SEO, UX, engineering).
Chicago Agency Guide to Hyvä Theme Migration
Towering Media, a Chicago Magento and Adobe Commerce agency, published a detailed migration framework for moving Magento stores from Luma or legacy frontends to the Hyvä theme. The guide explains why Hyvä improves Core Web Vitals (CWV) and site performance by replacing Knockout/RequireJS with Alpine.js and Tailwind, and documents a five-phase migration approach: discovery, planning, build, QA/performance verification, and launch/stabilize. It covers extension audits, checkout strategy (Hyvä Checkout, React Checkout Pro, or temporary Luma fallback), template mapping, image/asset optimization, CWV acceptance criteria (LCP, CLS, INP), load testing, and post-launch monitoring. The article includes anonymized client results (notable LCP and JS reductions and conversion uplift) and practical operational advice such as budgeting for extension rewrites and maintaining rollback plans.
