Introduction

Sahseh is a sophisticated e-commerce platform built on modern web technologies, designed to handle complex discount code operations at scale. Launched in 2019, the platform implements advanced algorithms for real-time coupon validation and application, serving the MENA region through a distributed architecture.

Technical Architecture

Frontend Architecture

The frontend is built on Vue.js 3 with Nuxt.js, implementing a robust component-based architecture:

• State Management: Pinia for predictable state mutations

• Routing: Vue Router with dynamic route handling

• UI Framework: TailwindCSS for utility-first styling

• Internationalization: Nuxt i18n module for Arabic/English support

• Performance: Implements lazy loading and component hydration

• API Integration: RESTful endpoints with JSON:API specification

Core Features Implementation

• Coupon Engine

  The platform’s core functionality is powered by:

  • Real-time validation system for coupon codes
  • Asynchronous processing of discount calculations
  • Rate limiting and abuse prevention mechanisms
  • Caching layer for frequently accessed codes
  • Automated expiry handling and cleanup

• Multi-Platform Integration

  Cross-platform compatibility achieved through:

  • Progressive Web App (PWA) implementation
  • Native bridge for mobile applications
  • Browser extension utilizing content scripts
  • Shared core logic across platforms
  • WebSocket connections for real-time updates

• Performance Optimizations

  • Implemented code splitting and lazy loading
  • Asset optimization and CDN distribution
  • Service Worker for offline capabilities
  • Memory-efficient state management
  • Optimized database queries and indexing
