TRVLR Sync

​

Overview

​

Key Features

• Bungie OAuth Integration: Custom PKCE handshake and secure token storage
• Manifest Management: Dual storage options (PostgreSQL JSON and S3 SQLite)
• Character Data Sync: Real-time synchronization of Destiny 2 character data
• Inventory Management: Track and manage in-game inventory
• Loadout Builder: Create and manage character loadouts
• Vendor Tracking: Monitor vendor inventories and rewards

​

Architecture

​

Technology Stack

• Frontend: Next.js 15, TypeScript, React
• Backend: Supabase Edge Functions, PostgreSQL
• Storage: Supabase Storage (S3-compatible) for SQLite manifests
• Authentication: Bungie.net OAuth 2.0 with PKCE
• Database: PostgreSQL with Row Level Security (RLS)
• Deployment: Vercel (frontend), Supabase (backend)

​

Getting Started

​

Prerequisites

• Node.js 18+ and pnpm
• Supabase CLI (>= v2.20.x)
• Bungie.net API credentials
• OpenSSL (for local HTTPS certificates)

​

Setup

1. Navigate to application directory:
   cd apps/trvlr-sync
   
2. Install dependencies:
   pnpm install
   
3. Generate SSL certificates (for local HTTPS):
   mkdir certs
   openssl req -x509 -newkey rsa:4096 -nodes \
     -keyout certs/dev.key -out certs/dev.crt \
     -subj "/CN=localhost" -days 365
   
4. Configure environment variables: Create .env.local:
   # Supabase Connection
   NEXT_PUBLIC_SUPABASE_URL=https://127.0.0.1:54321
   NEXT_PUBLIC_SUPABASE_ANON_KEY=<anon-key>
   SUPABASE_SERVICE_ROLE_KEY=<service-role-key>
   
   # Bungie API Credentials
   BUNGIE_CLIENT_ID=<your-client-id>
   BUNGIE_CLIENT_SECRET=<your-client-secret>
   BUNGIE_API_KEY=<your-api-key>
   
   # Application URLs
   APP_URL=http://localhost:3000
   NEXT_PUBLIC_SITE_URL=http://localhost:3000
   
5. Start Supabase locally:
   supabase start
   
6. Apply database migrations:
   supabase db reset
   
7. Run development server:
   pnpm dev
   

​

Bungie OAuth Flow

1. Initiate OAuth: User clicks “Connect Bungie Account”
2. PKCE Generation: Server generates code verifier and challenge
3. Redirect to Bungie: User authenticates with Bungie.net
4. Callback Handling: Server receives authorization code
5. Token Exchange: Exchange code for access/refresh tokens
6. Token Storage: Store tokens securely in bungie_accounts table

​

Edge Functions

• bungie-auth/init.ts: Initiates PKCE handshake and redirects to Bungie OAuth
• bungie-auth/callback.ts: Handles OAuth callback and token storage

​

Manifest Management

​

JSON Storage (PostgreSQL)

• Stored directly in destiny_manifest table
• Fast queries with PostgreSQL indexing
• Suitable for frequently accessed data

​

SQLite Storage (S3)

• Stored in Supabase Storage (S3-compatible)
• Metadata tracked in manifest_files table
• Suitable for large manifest files

​

Manifest Sync

• Fetches latest manifest from Bungie API
• Stores JSON version in PostgreSQL
• Stores SQLite version in S3 (if enabled)
• Updates manifest metadata

supabase functions schedule sync-manifest "0 0 * * *"

​

Database Schema

​

Tables

• bungie_accounts: Stores OAuth tokens and account metadata
• destiny_manifest: JSON manifest data
• manifest_files: SQLite manifest file metadata

​

API Endpoints

​

Authentication

• GET /api/auth/bungie/login - Initiate OAuth flow
• GET /api/auth/bungie/callback - Handle OAuth callback

​

Manifest

• GET /api/manifest - Get current manifest version
• POST /api/manifest/sync - Trigger manifest sync

​

Character Data

• GET /api/characters - Get user’s characters
• GET /api/inventory - Get character inventory
• GET /api/loadouts - Get saved loadouts

​

Deployment

​

Environment Variables

​

Vercel Deployment

1. Connect repository to Vercel
2. Set environment variables
3. Configure Supabase Edge Functions separately
4. Deploy frontend application

​

Troubleshooting

​

Common Issues

​

SSL Certificate Errors

• Issue: “Certificate verification failed” when connecting to local Supabase
• Solution: Ensure SSL certificates are generated correctly and paths are correct in environment variables.

​

OAuth Callback Failures

• Issue: OAuth callback not working or redirecting incorrectly
• Solution: Verify APP_URL and NEXT_PUBLIC_SITE_URL match your local development URL. Check Bungie API credentials.

​

Manifest Sync Failures

• Issue: Manifest sync not completing or errors during sync
• Solution: Check Bungie API key validity. Verify database connection and storage permissions. Review Edge Function logs.

​

Performance Tips

• Use JSON Storage: For frequently accessed data, use PostgreSQL JSON storage
• Use SQLite Storage: For large manifest files, use S3-compatible storage
• Schedule Syncs: Use scheduled Edge Functions to keep manifest up-to-date
• Cache Responses: Implement caching for manifest queries
