Deploy All Functions\n\n```bash\n# Deploy the ingestion cron job\nvt create cron jetstreamPoller --file src/ingestion/jetstream-poller.ts --schedule \"*/5 * * * *\"\n\n# Deploy the HTTP API\nvt create http anchorAPI --file src/api/anchor-api.ts\n\n# Deploy the social sync cron job\nvt create cron socialGraphSync --file src/social/social-graph-sync.ts --schedule \"0 2 * * *\"\n```\n\n### 2. Verify Deployments\n\n```bash\n# List your functions\nvt list\n\n# Check function status\nvt status jetstreamPoller\nvt status anchorAPI\nvt status socialGraphSync\n```\n\n### 3. Test the API\n\n```bash\n# Get your API URL\nAPI_URL=$(vt url anchorAPI)\n\n# Test endpoints\ncurl \"$API_URL/stats\"\ncurl \"$API_URL/global?limit=5\"\n```\n\n## Alternative: Manual Deployment\n\nIf you prefer the web interface:\n\n### 1. No Database Setup Required\n\nTables are automatically created when functions first run.\n\n### 2. Create Functions via Web Interface\n\n- Go to [val.town](https://val.town)\n- Create new cron function: `jetstreamPoller`\n- Copy code from `src/ingestion/jetstream-poller.ts`\n- Set schedule: `*/5 * * * *`\n\n### 3. Repeat for Other Functions\n\n- HTTP function: `anchorAPI` from `src/api/anchor-api.ts`\n- Cron function: `socialGraphSync` from `src/social/social-graph-sync.ts`\n (schedule: `0 2 * * *`)\n\n## Environment Variables\n\nNo environment variables are required for the basic deployment. All\nauthentication uses public APIs.\n\n## Testing the Deployment\n\n### 1. Test Data Ingestion\n\nMonitor the `jetstreamPoller` logs to ensure it's receiving and processing\ncheck-in events.\n\n### 2. Test API Endpoints\n\nUse the provided test script or Val Town CLI:\n\n```bash\n# Using the test script (update BASE_URL first)\n./scripts/test-api.sh\n\n# Or using Val Town CLI\nAPI_URL=$(vt url anchorAPI)\ncurl \"$API_URL/global?limit=5\"\ncurl \"$API_URL/stats\"\ncurl \"$API_URL/nearby?lat=52.0705&lng=4.3007&radius=5\"\n```\n\n### 3. Monitor Processing Logs\n\nCheck the `processing_log_v1` table to monitor ingestion health and performance.\n\n## Scaling Considerations\n\n### Performance Optimization\n\n- Monitor SQLite performance as data grows\n- Consider implementing pagination for large result sets\n- Add query timeout handling for long-running spatial queries\n\n### Rate Limiting\n\n- The social graph sync includes built-in rate limiting\n- Jetstream poller has a 45-second collection window\n- API endpoints have built-in limits (max 100 results per query)\n\n### Error Handling\n\n- All functions include comprehensive error handling\n- Failed address resolutions are cached to avoid retry storms\n- Processing logs track errors for monitoring\n\n## Monitoring and Maintenance\n\n### Health Checks\n\n- Monitor the `/stats` endpoint for system health\n- Check processing logs for ingestion errors\n- Monitor SQLite database size and performance\n\n### Database Maintenance\n\n- Periodically clean up old processing logs\n- Monitor address cache hit rates\n- Consider archiving old check-ins if storage becomes an issue\n\n### Updates and Schema Changes\n\n- When changing database schema, increment table versions (e.g., `checkins_v1` →\n `checkins_v2`)\n- Test schema migrations carefully in development\n- Consider data migration scripts for breaking changes\n\n## Troubleshooting\n\n### Common Issues\n\n1. **Jetstream connection failures**: Check network connectivity and Jetstream\n service status\n2. **Address resolution errors**: Verify AT Protocol network accessibility\n3. **Social graph sync failures**: Check Bluesky API rate limits and status\n4. **SQLite performance**: Monitor query execution times and optimize indexes\n\n### Debugging\n\n- All functions include detailed logging\n- Use Val Town's built-in debugging tools\n- Monitor function execution times and memory usage\n\n## Security Considerations\n\n- All API endpoints include proper CORS headers\n- No sensitive data is logged or stored\n- Public APIs are used for all external integrations\n- Rate limiting prevents abuse of external services\n\n## Integration with Anchor Client\n\nThe deployed AppView provides these

ATProto OAuth Implementation Guide\n\nComplete guide for implementing OAuth authentication with Bluesky/ATProto, based\non the book-explorer project's successful working implementation.\n\n## Overview\n\nATProto (AT Protocol) uses OAuth 2.0 with advanced security features. This guide\nprovides a complete manual implementation that works with Deno/Val Town,\nincluding:\n\n- **OAuth Discovery** - Dynamic endpoint discovery via well-known URLs\n- **S256 PKCE** - SHA256-based Proof Key for Code Exchange\n- **DPoP** - Demonstration of Proof-of-Possession with ES256 JWTs\n- **Nonce handling** - Anti-replay protection with automatic retry\n- **Token refresh** - Automatic token refresh when expired\n- **Session persistence** - SQLite storage for stateless operations\n\n## Prerequisites\n\n- Deno/TypeScript environment\n- Web framework (Hono recommended)\n- HTTPS domain for OAuth client metadata\n- SQLite for session persistence\n\n## Architecture Overview\n\nOur implementation consists of:\n\n1. **OAuth Client Metadata Endpoint** - Static JSON serving client info\n2. **OAuth Start Endpoint** - Initiates OAuth flow with handle resolution\n3. **OAuth Callback Handler** - Completes token exchange with DPoP\n4. **Session Management** - SQLite storage with DPoP key persistence\n5. **Authenticated API Helpers** - DPoP-authenticated requests with auto-refresh\n\n## Step 1: Database Schema\n\n```sql\n-- OAuth session storage with DPoP key binding\nCREATE TABLE oauth_sessions (\n did TEXT PRIMARY KEY,\n handle TEXT NOT NULL,\n pds_url TEXT NOT NULL,\n access_token TEXT NOT NULL,\n refresh_token TEXT NOT NULL,\n dpop_private_key TEXT NOT NULL, -- JWK format\n dpop_public_key TEXT NOT NULL, -- JWK format\n created_at INTEGER NOT NULL,\n updated_at INTEGER NOT NULL\n);\n```\n\n## Step 2: OAuth Client Metadata\n\n```typescript\n// Serve client metadata for OAuth discovery\napp.get(\"/client-metadata.json\", (c) => {\n const metadata = {\n \"client_id\": APP_CONFIG.CLIENT_ID,\n \"client_name\": APP_CONFIG.APP_NAME,\n \"client_uri\": APP_CONFIG.BASE_URL,\n \"logo_uri\": `${APP_CONFIG.BASE_URL}/favicon.ico`,\n \"redirect_uris\": [APP_CONFIG.REDIRECT_URI],\n \"scope\": \"atproto transition:generic\",\n \"grant_types\": [\"authorization_code\", \"refresh_token\"],\n \"response_types\": [\"code\"],\n \"application_type\": \"web\",\n \"token_endpoint_auth_method\": \"none\",\n \"dpop_bound_access_tokens\": true,\n };\n\n return c.json(metadata, 200, {\n \"Content-Type\": \"application/json\",\n });\n});\n```\n\n## Step 3: DPoP Implementation\n\n### DPoP Proof Generation\n\n```typescript\nasync function generateDPoPProofWithKeys(\n method: string,\n url: string,\n privateKey: CryptoKey,\n publicKey: CryptoKey,\n accessToken?: string,\n nonce?: string,\n) {\n // Export public key as JWK\n const jwk = await exportJWK(publicKey);\n\n // Create DPoP JWT payload\n const payload: any = {\n jti: crypto.randomUUID(),\n htm: method,\n htu: url,\n iat: Math.floor(Date.now() / 1000),\n };\n\n // Add nonce if provided (for anti-replay)\n if (nonce) {\n payload.nonce = nonce;\n }\n\n // Add access token hash for authenticated requests\n if (accessToken) {\n const encoder = new TextEncoder();\n const data = encoder.encode(accessToken);\n const digest = await crypto.subtle.digest(\"SHA-256\", data);\n payload.ath = btoa(String.fromCharCode(...new Uint8Array(digest)))\n .replace(/[+/]/g, (match) => match === \"+\" ? \"-\" : \"_\")\n .replace(/=/g, \"\");\n }\n\n // Create and sign DPoP JWT\n const dpopProof = await new SignJWT(payload)\n .setProtectedHeader({\n typ: \"dpop+jwt\",\n alg: \"ES256\",\n jwk: jwk,\n })\n .sign(privateKey);\n\n return { dpopProof };\n}\n```\n\n### DPoP Request Helper with Auto-Refresh\n\n```typescript\nasync function makeDPoPRequest(\n method: string,\n url: string,\n

Detects `invalid_token` error responses\n2. Uses refresh token to get new access token\n3. Updates stored session with new tokens\n4. Retries original request with fresh token\n\n## Common Issues and Solutions\n\n### 1. **\"invalid_token\" - Token Expired**\n\n- **Detection**:\n `{\"error\":\"invalid_token\",\"message\":\"\\\"exp\\\" claim timestamp check failed\"}`\n- **Solution**: Automatic token refresh implemented in `makeDPoPRequest`\n\n### 2. **\"use_dpop_nonce\" Error**\n\n- **Detection**: Response header `DPoP-Nonce` present\n- **Solution**: Extract nonce and retry with updated DPoP proof\n\n### 3. **DPoP Key Binding Issues**\n\n- **Cause**: Using different keys for token exchange vs. API calls\n- **Solution**: Store and reuse the same extractable ES256 key pair\n\n### 4. **Serverless State Management**\n\n- **Cause**: OAuth state lost between requests\n- **Solution**: Encode state data in the state parameter itself\n\n## Testing Your Implementation\n\n1. **Start OAuth Flow**: `POST /api/auth/start` with\n `{\"handle\": \"user.bsky.social\"}`\n2. **Complete Authorization**: Follow the returned `authUrl`\n3. **Verify Token Exchange**: Check successful callback handling\n4. **Test API Operations**: Verify read/write operations work\n5. **Test Token Refresh**: Wait for token expiration and verify auto-refresh\n\n## Production Considerations\n\n1. **HTTPS Required**: OAuth flows must use HTTPS\n2. **Session Security**: Store DPoP keys securely in encrypted database\n3. **Error Handling**: Implement comprehensive error handling and logging\n4. **Rate Limiting**: Respect AT Protocol rate limits\n5. **Token Cleanup**: Implement cleanup for expired sessions\n\n## Working Example Structure\n\n```\nbook-explorer/\n├── backend/\n│ └── index.ts # Complete OAuth + API implementation\n├── frontend/\n│ ├── components/\n│ │ ├── App.tsx # Session management + UI\n│ │ └── Login.tsx # OAuth initiation\n│ └── index.html\n├── shared/\n│ ├── config.ts # OAuth configuration\n│ └── types.ts # TypeScript definitions\n└── deno.json\n```\n\n## Final Result\n\n✅ **Complete OAuth Implementation**: No app passwords required\\\n✅ **DPoP Key Binding**: Consistent authentication with stored keys\\\n✅ **Automatic Token Refresh**: Seamless handling of expired tokens\\\n✅ **Nonce Handling**: Anti-replay protection with retry logic\\\n✅ **Session Persistence**: Stateless operations with SQLite storage\\\n✅ **Production Ready**: Comprehensive error handling and edge cases\n\nThis implementation successfully provides complete OAuth authentication for\nATProto, enabling both reading and writing operations without requiring app\npasswords. The book-explorer project demonstrates this working in production\nwith features like StoryGraph CSV import and bulk book status updates.\n",[],[1016],{"_104":1024,"_95":1025,"_155":1026,"_157":-5,"_158":140,"_159":1027,"_161":22,"_106":1028,"_100":1029,"_164":178,"_166":1030,"_167":22,"_168":-5,"_169":1031,"_98":1032},"bcc4ab42-75c4-11f0-801c-0224a6c84d84","CLAUDE.md","5847d28e-58b4-11f0-a0a5-f69ea79377d9",466,["D",1754814828944],11,"# CLAUDE.md\n\nThis file provides guidance to Claude Code (claude.ai/code) when working with\ncode in this repository.\n\n## Project Overview\n\nThis is the **Anchor AppView** - a location-based social feed generator and\nOAuth authentication system for the Anchor app, built on the AT Protocol\n(Bluesky) infrastructure. The system ingests check-in data from the\ndecentralized AT Protocol network, provides spatial and social feeds, and\nincludes a complete OAuth WebView implementation for mobile app integration.\n\n## Architecture\n\n### Entry Point and Deployment\n\n- **Main Entry**: `main.tsx` (Val Town HTTP function with\n `// @val-town anchordashboard` comment)\n- **Base URL**: `https://dropanchor.app` (configurable via `ANCHOR_BASE_URL` env\n var)\n- **Platform**: Single Hono-based web server deployed on Val Town using Deno\n runtime\n\n### Core Components\n\n1. **HTTP Server (main.tsx)** - Unified Hono server handling all routes:\n - OAuth authentication endpoints\n - AppView API endpoints (global, nearby, user, following feeds)\n - Mobile OAuth WebView pages\n - React frontend serving\n - Admin API endpoints\n\n2. **OAuth Authentication System (`backend/oauth/`)** - Complete OAuth 2.0 +\n DPoP implementation:\n - PKCE flow with automatic handle resolution and PDS discovery\n - Mobile app detection for WebView integration\n - Custom URL scheme redirect: `anchor-app://auth-callback`\n - Session management with SQLite storage\n\n3. **AppView Data Layer (`backend/api/anchor-api.ts`)** - AT Protocol compliant\n feed system:\n - Real-time ingestion from Jetstream\n - StrongRef address resolution and caching\n - Spatial queries using Haversine distance calculations\n - Social graph integration with Bluesky\n\n4. **React Dashboard (`frontend/`)** - Web interface for authentication and feed\n management\n\n### Key Technologies\n\n- **AT Protocol** - Decentralized social networking with OAuth 2.0 + DPoP\n authentication\n- **Val Town** - Serverless platform deployment with Deno runtime\n- **SQLite** - Database for check-ins, addresses, social graph, and OAuth\n sessions\n- **Jetstream** - Real-time AT Protocol firehose for data ingestion\n- **Hono** - Lightweight web framework for unified API serving\n- **React 18.2.0** - Frontend dashboard with TypeScript\n\n## Database Schema\n\nThe system uses five main tables:\n\n- `checkins_v1` - Main check-ins with coordinates and cached address data\n- `address_cache_v1` - Cached venue/address information from StrongRef\n resolution\n- `profile_cache_v1` - Cached user profile data (display names, avatars)\n- `user_follows_v1` - Social graph data for following-based feeds\n- `oauth_sessions` - OAuth session storage with DPoP keys and user profiles\n- `processing_log_v1` - Monitoring and operational logging\n\n## Development Commands\n\n### Deno Tasks\n\nThe project includes several Deno tasks for common development workflows:\n\n- `deno task quality` - Run formatter, linter, and all tests in sequence\n- `deno task quality:fix` - Same as quality but auto-fixes linting issues\n- `deno task fmt` - Format code using deno fmt\n- `deno task lint` - Run linter to check code quality\n- `deno task check` - TypeScript type checking for all source files\n- `deno task test` - Run all tests\n- `deno task test:unit` - Run unit tests only\n- `deno task test:integration` - Run integration tests only\n- `deno task test:watch` - Run tests in watch mode\n- `deno task deploy` - Deploy to Val Town using deploy script\n- `deno task debug` - Run debug script to check data and API status\n\n### Testing\n\n- `./scripts/test.sh` - Run complete test suite (unit + integration)\n- `deno test --allow-all` - Run all tests directly\n- Test files use comprehensive mocking for Val Town services (sqlite, blob\n storage)\n\n### Deployment\n\n- `./scripts/deploy.sh` - One-click deployment to Val Town using CLI\n- `vt create cron|http --file ` - Deploy individual functions\n- Requires Val Town CLI: `npm install -g @valtown/cli`\n\n### Debugging\n\n- `deno run --allow-net scripts/debug.ts` - Check data availability and API\n status\n- `deno run --allow-net scripts/debug.ts --check-data` - Check AT Protocol\n records only\n- `deno run --allow-net scripts/debug.ts --test-api` - Test API endpoints only\n\n## Key Features\n\n- **Real-time ingestion** via WebSocket polling every 5 minutes\n- **Embedded location data** with coordinates and address details included in\n check-in records\n- **Spatial queries** for nearby check-ins using coordinate-based distance\n calculations\n- **Social feeds** leveraging Bluesky's social graph for personalized content\n- **Duplicate detection** to prevent reprocessing of check-in events\n\n## API Endpoints\n\n**Base URL**: `https://dropanchor.app`\n\n### AppView API\n\n- `/api/global` - Recent check-ins from all users with pagination\n- `/api/nearby` - Spatial queries for check-ins within specified radius\n- `/api/user` - User-specific check-ins\n- `/api/following` - Check-ins from followed users (requires social graph sync)\n- `/api/stats` -

Address resolution operations\n\n## Mobile OAuth WebView Integration\n\nThe system includes a complete OAuth authentication flow designed for mobile app\nWebView integration:\n\n### Mobile Authentication Flow\n\n1. **iOS app loads WebView**: `https://dropanchor.app/mobile-auth`\n2. **User completes OAuth**: Beautiful mobile-optimized login interface with\n auto-completion\n3. **Mobile app detection**: Server detects WebView context via User-Agent and\n Referer headers\n4. **Custom URL scheme redirect**: Success page triggers\n `anchor-app://auth-callback` with tokens\n5. **iOS app handles callback**: Parse authentication data from URL parameters\n\n### Mobile App Detection Logic\n\n- User-Agent contains \"AnchorApp\"\n- Referer from `/mobile-auth` endpoint\n- iPhone Mobile user agents\n- Automatically routes mobile vs web authentication flows\n\n### Authentication Data Format\n\nThe mobile callback URL includes all necessary authentication data:\n\n```\nanchor-app://auth-callback?access_token=...&refresh_token=...&did=...&handle=...&session_id=...&avatar=...&display_name=...\n```\n\n### iOS Integration Requirements\n\n- **URL Scheme Registration**: `anchor-app` in Info.plist\n- **WebView Configuration**: Set User-Agent to \"AnchorApp\" for detection\n- **Secure Storage**: Store tokens in iOS Keychain for production apps\n- **Session Management**: Use session validation endpoints for token\n verification\n\n## Implementation Phases\n\nThe project is structured in phases:\n\n1. **Phase 1**: Core infrastructure and basic ingestion\n2. **Phase 2**: Address resolution and caching\n3. **Phase 3**: Global feed APIs and spatial queries\n4. **Phase 4**: Social features and following feeds\n\n## Val Town Deployment\n\nThe system deploys as a single unified HTTP function on Val Town:\n\n- **Main Function**: `anchordashboard` (main.tsx) - Unified Hono server handling\n all routes\n- **Deployment Command**: `deno task deploy` - Runs quality checks and pushes to\n Val Town\n- **Platform Integration**: Uses Val Town CLI (`vt push`) for deployment\n- **Database Initialization**: Automatic SQLite table creation on startup\n\n### Key Deployment Notes\n\n- **Single Entry Point**: All functionality consolidated in main.tsx for\n simplified deployment\n- **Static File Serving**: Frontend files served via Val Town utils with\n `serveFile`\n- **Environment Variables**: Base URL configurable via `ANCHOR_BASE_URL`\n- **Database Schema**: Version-based table naming for schema evolution\n\n## Val Town Development Guidelines\n\n### Code Standards\n\n- Use TypeScript for all Val Town functions\n- Never hardcode secrets - always use environment variables with\n `Deno.env.get('keyname')`\n- Import SQLite using\n `import { sqlite } from \"https://esm.town/v/stevekrouse/sqlite\"`\n- Import blob storage using `import { blob } from \"https://esm.town/v/std/blob\"`\n- Use `https://esm.sh` for external dependencies\n- All functions must be properly typed with TypeScript interfaces\n\n### SQLite Best Practices\n\n- When changing table schema, increment table name (e.g., `checkins_v1` →\n `checkins_v2`)\n- Always create tables before querying with `IF NOT EXISTS`\n- Use proper indexing for coordinate-based spatial queries\n- Initialize tables on every function execution for robustness\n\n### Val Town Triggers\n\n- **Cron Functions**: Export default async function with no parameters\n- **HTTP Functions**: Export default async function with `(req: Request)`\n parameter\n- **WebSocket**: Use standard WebSocket API for Jetstream connections\n\n### Error Handling\n\n- Let errors bubble up with full context rather than catching and logging\n- Use comprehensive error tracking in processing logs\n- Include timeout handling for WebSocket connections\n\n## Important Implementation Details\n\n- **StrongRef Address Resolution**: Check-in records contain `addressRef`\n StrongRefs that must be resolved to separate address records and cached\n\n### Check-in Record Structure (Current Format)\n\n#### AT Protocol Record Format (when queried directly)\n\n```json\n{\n \"uri\": \"at://did:plc:example/app.dropanchor.checkin/abc123\",\n \"value\": {\n \"text\": \"Just testing my new check-in records\",\n \"$type\": \"app.dropanchor.checkin\",\n \"createdAt\": \"2025-07-06T15:03:15Z\",\n \"coordinates\": {\n \"$type\": \"community.lexicon.location.geo\",\n \"latitude\": \"52.080178\",\n \"longitude\": \"4.3578971\"\n },\n \"addressRef\": {\n \"uri\": \"at://did:plc:example/community.lexicon.location.address/venue123\",\n \"cid\": \"bafyreicv3pecq6fuua22xcoguxep76otivb33nlaofzl76fpagczo5t5jm\"\n }\n }\n}\n```\n\n#### Jetstream Event Format (real-time ingestion)\n\n```json\n{\n \"did\": \"did:plc:wxex3wx5k4ctciupsv5m5stb\",\n \"time_us\": 1751824706067182,\n \"kind\": \"commit\",\n \"commit\": {\n \"rev\": \"3ltctwowylo26\",\n \"operation\": \"create\",\n \"collection\": \"app.dropanchor.checkin\",\n \"rkey\": \"3ltctwowntw26\",\n \"record\": {\n \"$type\": \"app.dropanchor.checkin\",\n \"addressRef\": {\n \"cid\": \"bafyreibhvynislx7vv52urqpm2vac6oeidvjb74m5pr3dmw3iztbengwbm\",\n \"uri\": \"at://did:plc:wxex3wx5k4ctciupsv5m5stb/community.lexicon.location.address/3ltctwolmqz2o\"\n },\n \"coordinates\": {\n \"$type\": \"community.lexicon.location.geo\",\n \"latitude\": \"52.0742969\",\n \"longitude\": \"4.3468013\"\n },\n \"createdAt\": \"2025-07-06T17:58:25Z\",\n \"text\": \"And one more which does include the social post as well.\"\n },\n \"cid\": \"bafyreifdepudvenhqnz4rk4j4dvyaaompafnj6r5ixamalpqmjlei2p43y\"\n }\n}\n```\n\n**CRITICAL**: The DID is at the **top level** in Jetstream events (`event.did`),\nnot in `commit.repo`. This is essential for proper data extraction during\nreal-time ingestion.\n\n### Jetstream Real-time Ingestion Process\n\n1. **Connect to Jetstream** with cursor-based resumption (1-hour lookback)\n2. **Filter events** for `kind: \"commit\"`,\n `collection: \"app.dropanchor.checkin\"`, `operation: \"create\"`\n3. **Extract data** from Jetstream event structure:\n - Author DID: `event.did` (top-level field)\n - Record key: `event.commit.rkey`\n - Record data: `event.commit.record`\n - Timestamp: `event.time_us` (for cursor tracking)\n4. **Duplicate detection** using `rkey` as primary key\n5. **Store in database** with proper URI construction:\n `at://${event.did}/${collection}/${rkey}`\n\n### Address Resolution Process\n\n1. **Ingest check-in** with `coordinates` and `addressRef` StrongRef\n2. **Store StrongRef** in `address_ref_uri` and `address_ref_cid` fields\n3. **Resolve StrongRef** to separate address record using address resolver\n4. **Cache address data** in `cached_address_*` fields for fast API responses\n5. **Return complete objects** in API feeds with resolved address data\n\n- **Social Graph Integration**: Following feeds require syncing follow\n relationships from Bluesky's public API\n- **Spatial Indexing**: Performance depends on proper SQLite indexing for\n coordinate-based queries\n- **Rate Limiting**: Social graph sync includes rate limiting to respect API\n constraints\n- **Error Handling**: Comprehensive error tracking for monitoring ingestion\n health\n- **Data Processing Pipeline**: Extracts coordinates from `coordinates` field\n and resolves `addressRef` StrongRefs to cache complete address data\n- **Hybrid Storage**: SQLite for relational data, blob storage for key-value\n caching\n\n## Testing Architecture\n\nThe project includes comprehensive testing:\n\n- **Unit Tests**: Mock Val Town services (sqlite, blob) for isolated testing\n- **Integration Tests**: Full API endpoint testing with realistic data flows\n- **Spatial Tests**: Haversine distance calculations with edge case handling\n- **Database Tests**: Schema validation and query testing with mock SQLite\n- **Test Coverage**: 31 tests across 5 test files ensuring reliability\n\n### Test Patterns\n\n- Use `assertAlmostEquals` for floating-point spatial calculations\n- Mock external services comprehensively but realistically\n- Test error conditions and edge cases (coordinate validation, cache expiry)\n- Validate TypeScript interfaces with proper type casting\n\nThe system is designed to scale within Val Town's resource limits while\nmaintaining full AT Protocol compatibility for decentralized social networking.\n",[],[1025],{"_104":1034,"_95":1035,"_155":1036,"_157":-5,"_158":140,"_159":1037,"_161":22,"_106":1038,"_100":32,"_164":178,"_166":1039,"_167":22,"_168":-5,"_169":1040,"_98":1041},"b51fdc92-767b-11f0-9005-0224a6c84d84","DATABASE_AUDIT.md","b51fdd46-767b-11f0-9005-0224a6c84d84",562,["D",1754893414022],"# Database Schema Audit Report\n\n## Overview\n\nThis document audits every database table and field against actual code usage to\nidentify what's truly needed vs unused/legacy code.\n\n## Tables Found in Codebase\n\n### Core Tables (from schema.ts)\n\n1. `checkins` -

Different parts of codebase\n using different field names!\n2. **Ensure `queries.ts` uses same field names as API** - This is critical for\n venue names to work\n3. **Verify all address data flows use consistent field names**\n\n## Original Recommendations\n\n1. **Fix field name inconsistencies FIRST** - This is the root cause of venue\n name issues\n2. **Remove unused tables** - Drop `address_cache` and `display_names` (not used\n in active code)\n3. **Migrate legacy tables** - Update code to use current schemas instead of v1\n tables\n4. **Keep migration system** -

TypeScript for all functions\n- Import SQLite:\n `import { sqlite } from \"https://esm.town/v/stevekrouse/sqlite\"`\n- Import blob storage: `import { blob } from \"https://esm.town/v/std/blob\"`\n- Use `https://esm.sh` for external dependencies\n- Never hardcode secrets - use `Deno.env.get('keyname')`\n- Let errors bubble up with full context rather than catching and logging\n\n### Data Storage Strategy\n\n- **SQLite**: Primary data (checkins, social graph, processing logs)\n- **Blob Storage**: Caching layer for address resolution with automatic expiry\n- **Schema Changes**: Increment table versions (e.g., `checkins_v1` →\n `checkins_v2`)\n- Always create tables with `IF NOT EXISTS` on function startup\n\n## 📈 Monitoring\n\n- Monitor `/stats` endpoint for system health\n- Check `processing_log_v1` for ingestion metrics\n- Use built-in logging and debugging tools\n- Monitor SQLite performance as data grows\n\n## 🔒 Security\n\n- All API endpoints include proper CORS headers\n- Public APIs only - no authentication required\n- Rate limiting built into external service calls\n- No sensitive data logged or stored\n\n## 🌐 AT Protocol Integration\n\nThe AppView is fully compatible with the AT Protocol ecosystem:\n\n- Ingests from Jetstream (official AT Protocol firehose)\n- Resolves DIDs using PLC directory\n- Fetches records via `com.atproto.repo.getRecord`\n- Integrates with Bluesky social graph APIs\n\n## 📄 License\n\nThis implementation is part of the Anchor project for location-based social\nnetworking on the AT Protocol.\n",[],[1044],{"_104":1053,"_95":1054,"_155":1055,"_157":-5,"_158":140,"_159":1056,"_161":22,"_106":1057,"_100":160,"_164":178,"_166":1058,"_167":22,"_168":-5,"_169":1059,"_98":1060},"4cb1adc6-75fd-11f0-aefa-0224a6c84d84","deno.json","5815fb42-58b4-11f0-aaa5-f69ea79377d9",536,["D",1754839122226],"{\n

Val Town Development Guide\n\nYou are an advanced assistant that helps programmers code on Val Town.\n\n## Core Guidelines\n\n- Ask clarifying questions when requirements are ambiguous\n- Plan large refactors or big features before you start coding\n- Provide complete, functional solutions rather than skeleton implementations\n- Test your logic against edge cases before presenting the final solution\n- Ensure all code follows Val Town's specific platform requirements\n- Always prefer small, single purpose, single responsibility components over\n large files that do many things\n- If a section of code is getting too complex, consider refactoring it into\n subcomponents\n- **Frontend = React, Backend = Hono, Database = Drizzle** - This is the way\n- **Write testable code** - Use dependency injection, follow SOLID principles,\n mock external services, write fakes instead of testing dependencies\n\n## Code Standards\n\n- Generate code in TypeScript or TSX\n- Add appropriate TypeScript types and interfaces for all data structures\n- Prefer official SDKs or libraries than writing API calls directly\n- Ask the user to supply API or library documentation if you are at all unsure\n about it\n- **Never bake in secrets into the code** - always use environment variables\n- Include comments explaining complex logic (avoid commenting obvious\n operations)\n- Follow modern ES6+ conventions and functional programming practices if\n possible\n- **Every function must be testable** - Accept dependencies as parameters,\n return predictable outputs\n- **Write tests alongside code** - Place `.test.ts` files next to the code they\n test\n\n## Project Structure\n\n### Project Organization\n\nWhen organizing a Val Town project, consider separating deployable code from\nlocal resources:\n\n```text\n├── your-project-name/ # Deployable directory (what Val Town will see)\n│ ├── backend/\n│ │ ├── database/\n│ │ │ ├── schema.ts # All table definitions, relations, and types\n│ │ │ ├── db.ts # Database connection and Drizzle instance \n│ │ │ ├── migrations.ts # Schema migration logic\n│ │ │ └── queries.ts # Reusable query functions\n│ │ ├── routes/ # Route modules\n│ │ │ ├── [route].ts\n│ │ │ └── static.ts # Static file serving\n│ │ └── index.ts # Main entry point\n│ ├── frontend/\n│ │ ├── components/\n│ │ │ ├── App.tsx\n│ │ │ └── [Component].tsx\n│ │ ├── index.html # Minimal HTML bootstrap file\n│ │ ├── index.tsx # React entry point with createRoot\n│ │ └── style.css # Global styles (prefer Tailwind classes)\n│ ├── shared/\n│ │ └── utils.ts # Shared types and

Project documentation\n└── AGENTS.md # AI assistant instructions\n```\n\n**Key Points:**\n\n- Only the contents of your main project directory will be deployed to Val Town\n- The `deno.json` file MUST be inside the deployment directory\n- Keep non-deployable resources outside the deployment directory\n\n### Deno Configuration\n\nPlace your `deno.json` in the deployable directory:\n\n```json\n{\n \"tasks\": {\n \"quality\": \"deno fmt && deno lint --fix && deno check **/*.ts **/*.tsx && deno test\",\n \"deploy\": \"deno task quality && vt push\",\n \"check\": \"deno check **/*.ts **/*.tsx\",\n \"test\": \"deno test\",\n \"fmt\": \"deno fmt\",\n \"lint\": \"deno lint --fix\"\n }\n}\n```\n\n## Frontend Architecture\n\n**Always use React** for Val Town frontends. Here's the opinionated approach:\n\n### Frontend Core Principles\n\n- **HTML is just a bootstrap file** - Keep it minimal, only load React\n- **No HTML fallbacks** - JavaScript is required, period\n- **Single Page Application** - Let React handle all rendering\n- **TypeScript everywhere** - Use `.tsx` files for all components\n- **Tailwind for styling** - Use the CDN version:\n ``\n\n### React Configuration\n\n- **Use latest versions** - Import React without version constraints\n- **JSX pragma required** - Start every `.tsx` file with\n `/** @jsxImportSource https://esm.sh/react */`\n- **No build step** - Import directly from ESM URLs\n- **Client-side only** - No SSR, inject initial data if needed\n\n## Backend Architecture\n\n### Hono Framework\n\n- Main entry point should be `backend/index.ts`\n- Export with `export default app.fetch`\n- Do NOT use Hono's serveStatic middleware\n- Use Val Town's `serveFile` utility for static assets\n- Re-throw errors in error handler for full stack traces\n\n### API Design\n\n- Create RESTful routes for CRUD operations\n- Use TypeScript interfaces for request/response types\n- Bootstrap initial data by reading and modifying HTML\n- Let errors bubble up with full context\n\n## Database with Drizzle ORM\n\nVal Town uses Turso (SQLite) under the hood. Use Drizzle ORM for type safety.\n\n### Key Concepts\n\n- **Schema-first approach** - Define all tables in `schema.ts`\n- **Single database instance** - Create one connection in `db.ts`\n- **Type-safe queries** - Use Drizzle's query builder\n- **Migrations** - Track schema changes with versioned migrations\n\n### Database Best Practices\n\n- Use singular table names (e.g., `user` not `users`)\n- Define relations for efficient querying\n- Add indexes** on foreign keys and frequently queried columns\n- Use transactions** for multi-table operations\n- Handle SQLite limitations - No complex ALTER TABLE\n- Limited ALTER TABLE support\n- Change table names instead of altering\n- Always run migrations before queries\n\n### Common Patterns\n\n- **Simple CRUD**: Use Drizzle's select, insert, update, delete\n- **Relations**: Use `db.query` for nested data\n- **Complex joins**: Use select with join methods\n- **Raw SQL**: Use `db.run(sql`)`` when needed\n\n## Testing Strategy\n\n### Testing Core Principles\n\n- Write tests first or ensure code is testable\n- Place test files next to code: `user.ts` → `user.test.ts`\n- Mock all external dependencies\n- Test behavior, not implementation\n\n### Writing Testable Code\n\n```typescript\n// BAD: Hard to test\nexport async function getUser(id: string) {\n const user = await db.select().from(userTable).where(eq(userTable.id, id));\n return user[0];\n}\n\n// GOOD: Testable with dependency injection\nexport async function getUser(id: string, dbProvider = db) {\n const user = await dbProvider.select().from(userTable).where(\n eq(userTable.id, id),\n );\n return user[0];\n}\n```\n\n### SOLID Principles\n\n1. **Single Responsibility** - Each function does one thing\n2. **Open/Closed** - Use composition over modification\n3. **Liskov Substitution** - Interfaces should be substitutable\n4. **Interface Segregation** - Small, focused interfaces\n5. **Dependency Inversion** - Depend on abstractions\n\n### Running Tests\n\n```bash\ndeno test # Run all tests\ndeno test user.test.ts # Run specific test\ndeno task quality # Includes tests in quality check\n```\n\n## TypeScript Configuration\n\n### Type Checking\n\n- Use `deno check` before deployment\n- Add explicit types for function parameters and returns\n- Define interfaces for all data structures\n- External libraries from esm.sh include types automatically\n\n### TypesSript Best Practices\n\n- Leverage TypeScript's strict mode\n- Type API responses for client-side safety\n- Use type-only imports: `import type { SomeType }`\n- Ignore Bun-specific errors if they appear\n\n## Dependency Management\n\n### Import Strategy\n\n- **Use latest versions** - No version pinning needed\n- **Import from esm.sh**: `https://esm.sh/package`\n- **Trust CDN resolution** - esm.sh handles compatibility\n- **Central deps file** - Use `deps.ts` for complex projects\n\n### Common Imports\n\n```typescript\n// React (with pragma)\n/** @jsxImportSource https://esm.sh/react */\nimport React from \"https://esm.sh/react\";\n\n// Drizzle ORM\nimport { drizzle } from \"https://esm.sh/drizzle-orm/libsql\";\n\n// Hono\nimport { Hono } from \"https://esm.sh/hono\";\n```\n\n## Development Workflow\n\n### Task Commands\n\n1. **During development**: `deno task check` - Catch type errors\n2. **Before committing**: `deno task quality` - Format, lint, type check, test\n3. **To deploy**: `deno task deploy` - Quality checks then deploy\n\n### Deployment Process\n\n```bash\ndeno task deploy # Runs quality checks first\n```\n\n- Fix any issues before deployment succeeds\n- Environment variables managed in Val Town interface\n- Only deployment directory contents are uploaded\n\n## Val Town APIs\n\n### Triggers\n\n1. **HTTP Trigger** - Web APIs and endpoints\n2. **Cron Triggers** - Scheduled tasks (1 min minimum on pro)\n3. **Email Triggers** - Process incoming emails\n\n### Standard Libraries\n\n- **Blob Storage**: `import { blob } from \"https://esm.town/v/std/blob\"`\n- **SQLite**: Use Drizzle ORM instead of raw SQL\n- **OpenAI**: `import { OpenAI } from \"https://esm.town/v/std/openai\"`\n- **Email**: `import { email } from \"https://esm.town/v/std/email\"`\n\n### Utility Functions\n\n### Importing Utilities\n\nAlways import utilities with version pins to avoid breaking changes:\n\n```ts\nimport {\n readFile,\n serveFile,\n} from \"https://esm.town/v/std/utils@85-main/index.ts\";\n```\n\n### Available Utilities\n\n**serveFile** - Serve project files with proper content types\n\nFor example, in Hono:\n\n```ts\n// serve all files in frontend/ and shared/\napp.get(\"/frontend/*\", (c) => serveFile(c.req.path, import.meta.url));\napp.get(\"/shared/*\", (c) => serveFile(c.req.path, import.meta.url));\n```\n\n**readFile** - Read files from within the project:\n\n```ts\n// Read a file from the project\nconst fileContent = await readFile(\"/frontend/index.html\", import.meta.url);\n```\n\n**listFiles** - List all files in the project\n\n```ts\nconst files = await listFiles(import.meta.url);\n```\n\n## Platform Specifics\n\n### Important Limitations\n\n- **Redirects**: Use\n `new Response(null, { status: 302, headers: { Location: \"/path\" }})`\n- **No binary files** - Text files only\n- **No Deno KV** - Use SQLite instead\n- **No browser APIs** - No alert(), prompt(), confirm()\n- **Automatic CORS** - Don't import CORS middleware\n\n## Common Gotchas\n\n### Environment\n\n- Val Town runs on Deno, not Node.js\n- Shared code can't use Deno-specific APIs\n- Use esm.sh for browser/server compatibility\n\n### Hono Issues\n\n- NEVER import serveStatic middleware\n- NEVER import CORS middleware\n- Use Val Town's utilities instead\n- **ALWAYS import Val Town utilities directly** - Never create placeholder\n functions for `serveFile`, `blob`, `email`, etc. Import them from\n `https://esm.town/v/std/utils/index.ts` or their respective standard library\n modules from the start\n\n## Migration Strategy\n\n### Principles\n\n- Track migration history in dedicated table\n- Make migrations idempotent\n- Control with environment variables\n- Test thoroughly before deployment\n\n### Best Practices\n\n- Plan schema changes carefully\n- Consider performance impact\n- Backup before destructive changes\n- Remember SQLite limitations\n- Use emojis/unicode instead of images\n- Let errors bubble up with context\n- Prefer APIs without keys (e.g., open-meteo for weather)\n- Add
