ESM requires explicit file extensions in import paths. Add .js
extensions to all relative imports in API files and services,
even though source files are .ts (they compile to .js).
This fixes ERR_MODULE_NOT_FOUND errors on Vercel.
- Move ogStore, ogHtml, and articleMeta from src/services/ to api/services/
- Update imports in article-og.ts and article-og-refresh.ts
- Update import paths in articleMeta.ts (lib/profile and src/config/relays)
- Remove old files from src/services/
- Clean up ESLint config to only reference api/**/*.ts
This fixes the ERR_MODULE_NOT_FOUND error on Vercel by ensuring
serverless functions can access the service modules.
- Add ogStore service for Redis get/set operations
- Extract shared logic: ogHtml (generateHtml, escapeHtml) and articleMeta (relay/gateway fetching)
- Refactor article-og endpoint to read from Redis, try gateway on miss, trigger background refresh
- Add article-og-refresh endpoint for background relay fetching and caching
- Update vercel.json with refresh function config
- Remove WebSocket dependencies from main OG endpoint for faster crawler responses
