PokeCardIndex
Full-stack Pokemon TCG platform. Browse, search, and track over 20,000 cards across 172 sets with real-time market pricing, community sentiment features, and an interactive galaxy-style explorer called the Pokeverse.
Everything was fragmented
Pokemon TCG collectors lacked a single platform that combined a complete card database, real-time pricing across multiple conditions and grading companies, personal collection tracking with finish-level granularity (holofoil, reverse holo, etc.), and community engagement.
Existing tools were fragmented: you'd check one site for prices, another for set lists, and a spreadsheet for your collection.
One platform that brings everything together
Built PokeCardIndex as a full-stack web application that combines card data, pricing, collection management, and community features into a single polished interface.
Card Database
20,000+ cards across 172 sets and 17 series, sourced from the Pokemon TCG API and mirrored in Supabase. Full metadata: HP, types, attacks, weaknesses, resistances, rarity. Updated daily.
Real-Time Market Pricing
Scrydex API integration for NM, LP, MP, HP, and Damaged conditions. Graded prices from PSA, CGC, BGS. Price history charts track value trends over time.
Multi-Currency Support
Prices in 7 currencies (USD, GBP, EUR, CAD, AUD, JPY, CHF) using live exchange rates. Auto-detected from user's country on signup.
Collection Tracking
Add cards with specific finishes (normal, holofoil, reverse holo). Track quantities, add entire sets at once. Grid, table, and binder view modes.
Community Sentiment
Like/dislike voting system with aggregated rankings surfacing the most and least liked cards across the community.
The Pokeverse
Interactive galaxy/timeline visualization for exploring sets and cards. Real-time presence via Supabase Realtime shows other users' cursors live.
Search & Filtering
Debounced search with structured queries (name:, set.name:, number:) and advanced filters for finding specific cards instantly.
Authentication
Supabase Auth with email, Google, and Discord OAuth. User profiles with preferences and collection data.
Built for scale and speed
Under the hood
In-memory caching layer with stale-while-revalidate strategy (2-minute stale window, 10-minute expiry) and a revalidation queue to minimize redundant API calls.
Supabase Edge Function proxy to handle CORS restrictions when calling the Scrydex pricing API from the browser.
Real-time presence system using Supabase Realtime channels (broadcast + presence) for the Pokeverse multi-cursor experience.
SEO infrastructure including programmatic sitemap generation for 19,000+ pages, schema markup, canonical URLs, and internal linking, for a single-page React app.
90+ database migrations managing the evolving schema across card data, pricing, collections, voting, and user profiles.
Image optimization pipeline with WebP/PNG fallback support and Supabase storage integration for reliable card image delivery.
