Technical Implementation Plan - Wedding RSVP App Refactor

Comprehensive architectural blueprint integrating feature-based structure, layered architecture, and service patterns.

Reference: CONST-P1 (Modular Architecture), CONST-P8 (API First & Service Layer), CONST-P2 (AI-Driven Development)

Architecture Overview ✅ PHASE 1 COMPLETE

Tech Stack ✅ IMPLEMENTED

Layered Architecture Pattern

Following clean architecture principles with clear separation of concerns:

┌─────────────────────────────────────────┐
│            Presentation Layer           │
│  (UI Components, Pages, User Interface) │
├─────────────────────────────────────────┤
│             Application Layer           │
│    (Custom Hooks, State Management)    │
├─────────────────────────────────────────┤
│              Domain Layer               │
│   (Business Logic, Services, Utils)    │
├─────────────────────────────────────────┤
│           Infrastructure Layer          │
│     (APIs, Database, External Deps)    │
└─────────────────────────────────────────┘

Layer Responsibilities:

  1. Presentation: Stateless UI components, form handling, user interactions
  2. Application: Custom hooks, state orchestration, UI business logic
  3. Domain: Core business logic, validation, data transformations
  4. Infrastructure: API calls, database operations, external services
