3. Backend Architecture: Plugin-Based System

Plugin Architecture Philosophy

ProNature's backend implements an inversion of control (IoC) container pattern where all major components are "plugins" loaded and managed by a central App coordinator.

App.js (Container)
├── Loads plugins in sequence
├── Manages plugin lifecycle (import → init → start → stop)
├── Provides dependency injection
└── Coordinates graceful shutdown

Initialization Lifecycle

// backend/main.js - Plugin loading order
1. Config          // Load environment variables
   ↓
2. Db              // Establish MongoDB connection
   ↓
3. AccessManager   // Setup authentication & audit
   ↓
4. BL Managers     // Load business logic modules
   ├── GameObjectsManager    (asset CRUD)
   ├── GamesManager          (game definitions)
   ├── ScenariosManager       (scenarios)
   ├── UserManager           (user profiles)
   └── RulesManager          (game rules)
   ↓
5. WebServer       // Start Express server
   ↓
6. Controllers     // Mount API routes

Benefits of this design:

Testability - Mock plugins for unit testing
Modularity - Plugins are independent, loosely coupled
Scalability - Easy to add new business logic modules
Debugging - Clear initialization order aids troubleshooting

Core Backend Components

1. Database Abstraction Layer (`Db.js`)

Provides a unified interface for MongoDB operations:

// Generic CRUD operations
db.create(collection, document)
db.get(collection, id)
db.list(collection, query, projection)
db.update(collection, id, update)
db.delete(collection, id)

// Advanced operations
db.aggregate(collection, pipeline)        // MongoDB aggregation
db.search(collection, searchText)         // Full-text search

Performance Optimizations:

Connection pooling (max 256 connections)
Projection queries - Only fetch required fields
Index creation on frequently searched fields (name, tags)
Aggregation pipeline for complex queries

2. Access Manager (`AccessManager.js`)

Implements Role-Based Access Control (RBAC):

Roles:
├── user        (view own games, play)
├── editor      (create/edit games)
└── admin       (full system access)

Features:

Assertion Methods - am.user(), am.editor(), am.admin() for route protection
Audit Logging - Every API call logged with:
- User ID and email
- IP address
- User agent (browser/device fingerprint)
- Session ID
- Timestamp
- Action performed
History Tracking - Document-level version control
- Before/after snapshots
- Change timestamps
- Audit trail for compliance

3. Business Logic Managers

GameObjectsManager - 3D Asset Management

Asset Upload Flow:
1. Receive multipart upload (supports .glb, .gltf, images, videos)
2. Validate file type and size (max 150MB)
3. If image: Generate WebP thumbnails (500px height)
4. Store in MongoDB with metadata (tags, description, filename)
5. Return asset ID and URLs

GamesManager - Game Definition CRUD

Game Document Structure:
{
  _id: "game-123",
  title: "Nature Quiz",
  description: "Learn about ecosystems",
  thumbnail: "url/to/thumbnail.webp",
  scenario_ids: ["scenario-1", "scenario-2"],
  created_by: "user-456",
  created_at: timestamp,
  updated_at: timestamp,
  version: 2
}

ScenariosManager - Scene Graph Management

Scenario Structure:
{
  _id: "scenario-1",
  game_id: "game-123",
  title: "Forest Ecosystem",
  scenes: [
    {
      _id: "scene-1",
      objects: ["asset-1", "asset-2", ...],
      lights: [...],
      physics: {...}
    }
  ]
}

4. Express Application (`WebServer.js`)

Middleware stack for production-grade API:

Incoming Request
  ↓ (compression) - gzip response
  ↓ (parsing) - JSON/form parsing
  ↓ (session) - Load session from MongoDB
  ↓ (auth) - Passport authentication
  ↓ (CORS proxy) - Cross-origin handling
  ↓ (route matching) - Express router
  ↓
Controller → Business Logic → Database
  ↓
Response (compressed, status set, headers added)

HTTPS Configuration:

Optional self-signed certificates for development
Production certificates from Let's Encrypt or similar
Certificate validation optional to support development environments

4. Frontend Architecture: Vue 3 SPA

Application Bootstrapping

// src/main.js
- Create Vue app instance
- Register global plugins (Vuetify, Router, Pinia, API, i18n)
- Attach global mixin (ApplicationMixin)
- Mount to #app element

Plugin System

ProNature's frontend mirrors the backend's plugin architecture:

src/plugins/index.js
├── Vuetify Plugin
│   └── Registers Material Design components
├── Vue Router Plugin
│   └── Auto-routes from src/pages/ structure
├── Pinia Plugin
│   └── State management (prefs, snackbar)
├── API Plugin
│   └── Axios instance with base URL, interceptors
├── i18n Plugin
│   └── Language switching and translations
└── Params Plugin
    └── Global configuration parameters

Vue Router: File-Based Routing

Uses unplugin-vue-router for zero-config routing:

src/pages/
├── index.vue           → /
├── playground/
│   └── game/
│       └── [id].vue    → /playground/game/:id
├── manage/
│   ├── games.vue       → /manage/games
│   ├── game-objects.vue → /manage/game-objects
│   ├── scenarios.vue   → /manage/scenarios
│   └── preview/
│       └── [id].vue    → /manage/preview/:id
└── auth/
    ├── login.vue       → /auth/login
    └── register.vue    → /auth/register

Benefits:

Convention over configuration - Less boilerplate
Type-safe route names in TypeScript
Automatic lazy loading of route components
Prevents missing routes - Routes sync with file structure

State Management with Pinia

// src/stores/app.js
const appStore = defineStore('app', {
  state: () => ({
    prefs: {
      xr: { depthSense: true },
      ui: { 
        language: 'en',
        theme: 'light'
      }
    },
    snackbar: {
      show: false,
      text: '',
      color: 'primary',
      timeout: 3000
    }
  })
})

Store Persistence:

User preferences persisted to localStorage
Automatically restored on app load
Survives browser closes and window refreshes

Global Mixin Pattern

The GlobalMixin attached to all Vue components provides:

Default error handling
Snackbar helper methods
API call utilities
Language/theme switching
Performance monitoring

            ├── VideoPlayer (embedded media)
            ├── Particles (effects)
            └── InteractiveObjects (puzzles, games)

Asset Loading Pipeline

// Load 3D model
GLTFLoader
  ↓ (parse .glb binary)
  ↓ (decompress with DRACOLoader if needed)
  ↓ (load KTX2 textures with Basis)
  ↓ (apply materials)
  ↓
Generate three.Mesh objects with colliders
  ↓
Add to scene graph

Compression Benefits:

Format	Original	Compressed	Ratio
GLTF	5-10MB	500-1000KB	90%+ reduction
PNG Texture	2-4MB	100-300KB	95%+ reduction

WebXR Integration (VR/AR)

ProNature supports multiple extended reality modes:

Supported Experiences:
1. Desktop (standard mouse + keyboard)
2. VR (requires XR-compatible headset)
   └── WebXRManager with controller models
3. AR (mobile AR via WebXR or polyfills)
4. Anaglyph 3D (red/cyan glasses)
5. Stereo Sideby-Side (VR headset on mobile)

Controller Interaction in VR:

XR Controller Model Factory loads realistic hand/controller models
Ray casting for pointer interaction
Haptic feedback support

GameEngine Core (`src/lib/GameEngine.js`)

Central orchestrator for all 3D rendering and interaction:

GameEngine

   ├── Configure activation triggers
   └── Calculate completion conditions
   ↓
4. Scene transitions (via SceneSwitcher objects)
   ↓
5. Score calculation and presentation
   ↓
6. Submission to learning management system

6. Interactive Object System

Interactive Object Factory Pattern

InteractiveObject.js implements a factory pattern for creating specialized object types:

InteractiveObject.create(type, config)
  ↓
switch(type) {
  case 'generic': return new GenericObject(config)
  case 'character': return new CharacterObject(config)
  case 'text': return new TextObject(config)

Each interactive object implements:

{
  // Event handlers
  onHover(pointer) { },
  onClick(pointer) { },
  onDrag(pointer) { },
  
  // State management
  activate() { },
  deactivate() { },
  
  // Physics
  setRigidBody(shape, mass) { },
  
  // Animation
  playAnimation(name) { },
  
  // Lifecycle
  init() { },
  update(deltaTime) { },
  dispose() { }
}

7. Data Flow: From Game Creation to Gameplay

Game Creation Flow

1. Designer creates game in GameDesigner component
   ├── Defines game metadata (title, description)
   └── Creates scenarios

2. For each scenario:
   ├── Add 3D environment (load GLTF model)
   ├── Place interactive objects (puzzles, characters)
   ├── Configure object properties (text, images, behaviors)
   └── Set up scene transitions

3. Save scenario:
   ├── POST /api/game/
   ├── Backend validates with GameManager plugin
   └── MongoDB stores complete game definition

4. Generate thumbnail:
   ├── Three.js render to texture
   └── Sharp processes to WebP

Gameplay Data Flow

Player launches game:

1. Frontend:
   ├── Fetch /api/game/:id → get game metadata
   ├── Create GameEngine instance
   └── Initialize Three.js scene

2. GameManager:
   ├── Load scenario data
   ├── For each scene:
   │   ├── Load 3D models via GLTFLoader
   │   ├── Instantiate interactive objects
   │   ├── Create physics bodies via Rapier3D
   │   └── Attach event handlers
   └── Setup scene transitions

3. Gameplay:
   ├── User interacts with objects
   ├── PointerControls detects clicks/drags
   ├── InteractiveObject handles interaction
   ├── Telemetry logs action:
   │   └── POST /api/log/ with {user_id, action, timestamp}
   ├── Physics engine updates (Rapier3D)
   ├── Score updates
   └── MotionEngine plays animations

4. Scene completion:
   ├── Check win conditions
   ├── Calculate score
   ├── POST /api/history/ with game result
   └── Trigger scene transition or game end

5. Game finish:
   ├── Submit final score
   └── Show results screen

8. Advanced Features & Optimization Strategies

1. Asset Compression & Optimization

Problem: Large 3D assets slow down loading

Solutions Implemented:

.glb models (modern Exchange Format)
  ├── Draco compression (90%+ size reduction)
  └── Shared vertex data

Textures (60-80% of asset size)
  ├── KTX2 with Basis compression
  ├── GPU-native format → no CPU decompression
  └── Instant rendering on load

Images (thumbnails & previews)
  ├── WebP format (25-35% smaller than PNG/JPEG)
  ├── Sized appropriately (500px for browser, full res for preview)
  └── Lazy loaded on demand

2. Physics Optimization

Rapier3D WebAssembly Benefits:

Compiled down to native machine code
~100x faster than JavaScript physics
Off-main-thread execution possible
Enables complex collider hierarchies

// Only interactive objects need physics
✓ Puzzle pieces (need collision checks)
✓ Characters (need navigation)
✗ Static backdrop (visual only)

3. Rendering Performance

Culling Strategies:

Frustum culling (Three.js built-in) - Skip objects outside camera view
LOD (Level of Detail) - Use simplified models for distant objects
Instancing - Render many identical objects with one draw call

Statistics Monitoring:

Real-time FPS counter (StatsMonitor)
WebGL state tracking
Draw call counting
Memory usage graphs

4. State Management Optimization

Why Pinia over alternatives:

Tiny bundle footprint (~3KB vs 30KB+ for Vuex/Redux)
Minimal re-renders - Fine-grained reactivity
Perfect for game state (frequently updated)

5. Authentication & Session Security

User Login Flow:

1. POST /login with email/password
2. Passport validates (local strategy)
3. AccessManager creates audit log entry
4. Session stored in MongoDB
   └── Prevents in-memory bloat on server restart
5. Session cookie sent to client (HttpOnly + Secure)
6. Subsequent requests include cookie
7. Express-session middleware validates

9. Architectural Design Patterns Used

1. Plugin Architecture

Where: Backend (App, Db, AccessManager, Business Logic Managers)
Why: Modular, testable, scalable
Benefit: Easy to disable/swap components during testing

2. Factory Pattern

Where: InteractiveObject, GameObject creation
Why: Object instantiation based on type string
Benefit: Extensible - add new game types without modifying factory

3. Observer Pattern

Where: Vue reactivity, event emitters
Why: Decouple components from direct dependencies
Benefit: Dynamic interaction handling, telemetry logging

4. MVC/MVVM

Backend: MVC (Controllers → Business Logic → Models)
Frontend: MVVM (Components → Stores → API)
Benefit: Clear separation of concerns

5. Middleware Pipeline

Where: Express middleware stack
Why: Cross-cutting concerns (compression, auth, logging)
Benefit: Reusable, composable, easy to debug

6. Singleton Pattern

Where: GameEngine, GameManager (per session)
Why: Single 3D context, single game state
Benefit: No duplication of expensive resources

7. Strategy Pattern

Where: Passport authentication strategies
Why: Multiple auth methods (local, Google, Facebook)
Benefit: Pluggable auth backends

13. Lessons Learned & Best Practices

1. Choose Specialization Over Generalization

Why Vite > Webpack: Vite is optimized for modern web dev, not config flexibility. This focus enables fast iteration crucial for 3D asset development.

2. Database Schema Flexibility is Valuable

Why MongoDB > SQL: Educational games have varied asset types, physics models, and interactions. MongoDB's flexible schema accommodates experimentation.

3. Compression is Non-Negotiable for 3D

Impact:

Without Draco: 10MB load time
With Draco: 1MB load time
UX improvement: 10x faster

4. Physics Simulation in WebAssembly

Why Rapier3D > JavaScript physics:

Performance: 100-1000x faster
Quality: Realistic interactions
Battery: Better on mobile

5. Plugin Architecture Scales

Pattern Benefits:

Easy to add GameRulesManager, AchievementManager
Mockable for testing
Independently deployable in microservices

6. Audit Everything

Why it matters:

Compliance (GDPR, FERPA for education)
Debugging production issues
Learning analytics
Fraud detection
