Repository

This issue belongs in Fundable-Protocol/Backend under indexer/.

Migrated from https://github.com/Fundable-Protocol/stellar_indexer/issues/1.

• Creating cursor or indexed-event tables
• Implementing DB connection factories
• Docker Compose setup

Acceptance Criteria

• Migration tooling is installed and configured
• bun run db:generate or equivalent exists
• bun run db:migrate or equivalent exists
• bun run type-check passes
• bun run test passes
• bun run lint passes
• bun run indexer:type-check passes
• bun run indexer:test passes
• bun run indexer:lint passes

Dependencies

• Bun/Turborepo scaffold

Suggested Files or Packages

Hi maintainer,

I’d like to take on this issue. I can set up PostgreSQL dependencies, Drizzle ORM migration tooling, Bun scripts, migration structure, and documentation while keeping the implementation within the defined scope. I’ll also ensure all required type-check, lint, and test commands pass and update bun.lock accordingly.

Thanks!
