Smart Glasses Note-Taking App: Implementation Plan

Implementation Phase 1: Core Code

Data Models & Interfaces

• Define TypeScript interfaces for all data types (using 'I' suffix, e.g., NoteI)
• Create in-memory data stores to use during development
• Design abstraction layers to eventually support MongoDB & R2

Core Services

• Implement temporary file storage service (to replace R2 later)
• Create event streaming service for real-time updates
• Develop recording service with AugmentOS SDK integration
• Build notes service with CRUD operations

API Endpoints

• Build notes API endpoints (GET, POST, PUT, DELETE)
• Implement recordings API endpoints (GET, POST)
• Create SSE endpoint for real-time events
• Add authentication middleware

Implementation Phase 2: Infrastructure Setup (After Code Completion)

• Configure MongoDB database
• Set up Cloudflare R2 bucket for audio storage
• Create environment variables template
• Swap in-memory stores with MongoDB
• Replace file storage with R2 integration
