Dawarich Maps V2 - Incremental Implementation Guide

🎯 Overview

This is a production-ready, incremental implementation guide for reimplementing Dawarich's map functionality using MapLibre GL JS with a mobile-first approach.

✨ Key Innovation: Incremental MVP Approach

Each phase delivers a working, deployable application. You can:

• ✅ Deploy after any phase - Get working software in production early
• ✅ Get user feedback - Validate features incrementally
• ✅ Test continuously - E2E tests catch regressions at each step
• ✅ Rollback safely - Revert to any previous working phase

🏗️ Architecture Principles

1. Frontend-Only Implementation

• No backend changes - Uses existing API endpoints
• Client-side GeoJSON transformation
• ApiClient wrapper for all API calls

2. Rails & Stimulus Best Practices

• Stimulus values for configuration only (NOT large datasets)
• AJAX data fetching after page load
• Proper cleanup in disconnect()
• Turbo Drive compatibility
• Outlets for controller communication

3. Mobile-First Design

• Touch-optimized UI components
• Bottom sheet pattern for mobile
• Progressive enhancement for desktop
• Gesture support (swipe, pinch, long press)

4. Performance Optimized

• Lazy loading for heavy components
• Viewport-based data loading
• Progressive loading with feedback
• Memory leak prevention
• Service worker for offline support

🚀 Quick Start

1. Review Phase Overview

# Understand the incremental approach
cat PHASES_OVERVIEW.md

# See all phases at a glance
cat PHASES_SUMMARY.md

2. Start with Phase 1 MVP

# Week 1: Implement minimal viable map
cat PHASE_1_MVP.md

# Create files as specified in guide
# Run E2E tests: npx playwright test e2e/v2/phase-1-mvp.spec.js
# Deploy to staging
# Get user feedback

3. Continue Incrementally

# Week 2: Add routes + navigation
cat PHASE_2_ROUTES.md

# Week 3: Add mobile UI
# Request: "expand phase 3"
# ... continue through Phase 8

2. Existing API Endpoints

All endpoints are documented in PHASE_1_FOUNDATION.md:

• GET /api/v1/points - Paginated points
• GET /api/v1/visits - User visits
• GET /api/v1/areas - User-defined areas
• GET /api/v1/photos - Photos with location
• GET /api/v1/maps/hexagons - Hexagon grid data
• GET /api/v1/settings - User settings

3. Implementation Order

Follow the phases in order:

1. Foundation → API client, transformers
2. Core Layers → Points, routes, heatmap
3. Advanced Layers → Fog, visits, photos
4. UI Components → Date picker, settings, mobile UI
