Feature: Comprehensive Cloud Persistence Architecture #3
Description
Feature Request: Comprehensive Cloud Persistence Architecture
Current Limitation
The app currently only supports local storage via JSON export/import. This limits collaboration, version control, and cross-device access.
Comprehensive Cloud Persistence Vision
1. Multi-tier Storage Strategy
Immediate Persistence (Real-time)
- Every change auto-saves to cloud within 500ms (debounced)
- Conflict-free replicated data types (CRDTs) for concurrent editing
- Offline-first with automatic sync when connection restored
- Local IndexedDB cache for instant loads
Version Control
interface ProjectVersion {
id: string
projectId: string
timestamp: number
changes: ChangeSet[]
author: string
message?: string // "Added new screenshot", "Updated text overlay"
snapshot: CompressedProjectData
parentVersion?: string // For branching
}Project States
- Draft: Auto-saved every change, no manual save needed
- Published: Locked versions for production use
- Template: Shareable starting points for others
- Archive: Soft-deleted projects with 30-day recovery
2. Advanced Collaboration Features
Real-time Collaboration
- Multiple users editing simultaneously (Google Docs style)
- Live cursors showing where others are working
- Presence indicators (who's currently viewing/editing)
- Comment threads on specific elements
- Change attribution (who changed what and when)
Permission System
enum Permission {
OWNER = 'owner', // Full control
EDITOR = 'editor', // Can edit
COMMENTER = 'commenter', // Can comment only
VIEWER = 'viewer' // Read-only
}
interface ProjectAccess {
projectId: string
userId: string
permission: Permission
grantedBy: string
grantedAt: Timestamp
expiresAt?: Timestamp // For temporary access
}3. Smart Storage Optimization
Asset Management
- Deduplicate identical images across projects
- Progressive image loading (thumbnail → full resolution)
- Smart CDN caching with Cloudflare/Fastly
- Automatic format conversion (WebP for web, original for export)
- Storage quotas with usage analytics
Data Structure
interface CloudProject {
// Metadata (Firestore)
id: string
userId: string
teamId?: string
name: string
createdAt: Timestamp
updatedAt: Timestamp
lastAccessedAt: Timestamp
version: number
tags: string[]
isTemplate: boolean
templateCategory?: string
analytics: {
exports: number
views: number
clones: number
}
// Large Data (Cloud Storage)
screenshotsRef: StorageReference[]
assetsRef: StorageReference[]
// Structured Data (Firestore subcollection)
screens: FirestoreCollection<Screen>
// Permissions (Firestore subcollection)
access: FirestoreCollection<ProjectAccess>
// History (Firestore subcollection)
versions: FirestoreCollection<ProjectVersion>
}4. Intelligent Sync & Conflict Resolution
Sync Strategy
- Operational Transformation (OT) for text edits
- Last Write Wins (LWW) for position/style changes
- Three-way merge for complex conflicts
- Automatic conflict resolution with optional manual override
Offline Capabilities
interface OfflineQueue {
operations: Operation[]
lastSyncTimestamp: number
pendingUploads: File[]
conflictResolutionStrategy: 'auto' | 'manual'
}5. Advanced Features
AI-Powered Features

6. Performance & Scalability
Caching Layers
- Browser Cache: Service Worker for offline access
- Edge Cache: CDN for global asset delivery
- Database Cache: Redis for frequently accessed data
- Application Cache: In-memory caching for active projects
Data Pipeline
User Action → Local State → IndexedDB → Firestore → BigQuery (Analytics)

9. Monitoring & Analytics
User Analytics
interface ProjectAnalytics {
projectId: string
metrics: {
totalEdits: number
editDuration: number[]
exportCount: number
shareCount: number
deviceTypes: Record<DeviceType, number>
featureUsage: Record<string, number>
}
userJourney: Event[]
abTestVariants: string[]
}System Monitoring
