Phase 0 - Foundation: - Restructure into npm workspace monorepo (packages/core, api, scraper) - PostgreSQL 17 + TimescaleDB schema (15 tables incl. hypertables) - Docker Compose for local dev (PostgreSQL on 5433 + Qdrant) - Express 5 API on port 3200 with 6 routes - Seed script to migrate 159 transceivers + 42 standards from npm package - Erik server setup script + PM2 ecosystem config Phase 1 - Scraper Engine: - Crawlee + Playwright framework with pg-boss scheduler - FS.com scraper (PlaywrightCrawler, anti-bot workaround) - Optcore.net scraper (WP REST API enumeration + PlaywrightCrawler) - Uses /wp-json/wp/v2/product to get 2000+ product URLs - Playwright renders individual product pages for price extraction - Cisco TMG Matrix scraper (compatibility data) - News RSS aggregator (optics.org, SPIE, Network World, Nature Photonics) - Keyword relevance scoring for transceiver/fiber topics - xml2js with malformed XML sanitization - SHA-256 content hashing for change detection (skip unchanged records) - pg-boss v10 with explicit queue creation before scheduling
