Supabase + Solana Indexing Template

[GuiBibeau]

Background

The Solana Foundation maintains a templates repo with both official and community templates. Developers use these templates with create-solana-dapp to quickly scaffold projects.

Many Solana dApps need efficient ways to index and query on-chain data for performant user experiences. This task proposes adding a Supabase + Solana Indexing template that demonstrates how to index data from a Solana program and make it queryable through Supabase.

Goal

Add a community template at community/supabase-solana-indexing that includes:

• A Next.js + Tailwind + TypeScript application with Supabase integration
• Solana program account data indexing
• Real-time data synchronization from on-chain to Supabase
• Query examples for common use cases
• Performance optimization techniques

---

Deliverables

1. community/supabase-solana-indexing/ directory with working template code
2. README.md explaining:
   • Supabase project setup and database schema design
   • Account subscription and data fetching strategies
   • Real-time sync implementation approach
   • Query optimization and indexing best practices
   • Links to Supabase and Solana documentation
3. Indexing components:
   • Account subscription service for monitoring on-chain changes
   • Data transformation and normalization logic
   • Supabase client configuration
   • Error handling and retry mechanisms
4. Example queries:
   • Filtering and sorting indexed data
   • Pagination implementation
   • Real-time subscriptions to data changes
5. Database schema files:
   • SQL migrations for table creation
   • Indexes for query optimization
6. package.json with a create-solana-dapp block for post-install guidance
7. Type definitions for indexed data structures
8. Registration in templates.json so template is discoverable under Community Templates

---

Acceptance Criteria

• A new directory community/supabase-solana-indexing exists with a scaffolded Next.js + Tailwind + TypeScript project
• Supabase is integrated with proper client initialization
• Example demonstrates indexing data from a Solana program
• Real-time synchronization is implemented and documented
• Query examples cover common use cases
• README.md includes detailed implementation guide
• Template is registered in templates.json
• pnpm create solana-dapp --template supabase-solana-indexing works end-to-end
