ScanPricer
Architecture.

Designing a high-performance Amazon Europe price comparator with Next.js 15, Tailwind CSS, TypeScript, and a real-time API integration engine.

Tech Stack
  • FrameworkNext.js 15
  • Data LayerPA-API 5.0 + Zod
  • Infrastructure Vercel Edge
  • CachingUpstash Redis

Building a platform that compares thousands of products across multiple European countries in real-time requires more than just a good idea; it demands a robust, scalable, and highly optimized technical architecture.

Built for Speed

ScanPricer was designed from the ground up to be ultra-fast. From Server Components to edge caching, every layer of the stack is optimized for minimum latency.

01 // The Core Framework

Next.js 15 & App Router.

The heart of ScanPricer lies in the latest version of Next.js, fully leveraging the App Router for modern web patterns.

Server Components (RSC)

JavaScript is kept on the server, sending only HTML to the client for instant loading and perfect SEO.

REDUCED_BUNDLE_SIZE

Dynamic Routing & i18n

Managing 5 languages (FR, EN, ES, IT, DE) via next-intl and an intelligent middleware for locale prefixes.

FRDEENES
02 // Reliability

Type Safety with TypeScript.

In a project handling complex Amazon product schemas and nested translations, TypeScript is non-negotiable for stability.

Zero Runtime Errors

Catch bugs during development, long before they ever reach production.

Self-Documenting

Interfaces act as living documentation that's always up-to-date with reality.

Confidence

Refactoring core data structures is safe, predictable, and fully checked.

03 // Data Performance

Official API & Edge Caching.

How do we synchronize Amazon prices in real-time across borders while respecting strict API quotas and maintaining sub-second response times?

API Engine & Infrastructure

PA-API

Full compliance with Amazon Product Advertising API 5.0 for legitimate, real-time price synchronization.

Zod

Strict schema validation to safely parse and normalize complex JSON payloads from regional endpoints.

Redis

Upstash Redis: Smart edge caching to protect API rate limits and serve frequent searches instantly.

04 // Growth

SEO: The Edge of Growth.

A price comparator lives and dies by its organic search visibility. We implemented an aggressive technical SEO strategy.

Hreflang Automation

Automated translation linking ensures Google serves the correct regional version to the right audience.

Performance Assets

WebP delivery with exact sizing for a perfect Lighthouse score and immediate visual stability.
