v3.0.0 — HyperIndex V3 Is Here 🚀

Highlights

3× faster backfill (and faster still on v3.1 — ~50,000 events/sec on average)
New unified handlers API: indexer.onEvent() / indexer.onBlock() — no more generated package, envio package 88 MB smaller
Powerful where option: conditional event handlers, per-chain filters, and per-event start blocks
ESM migration with top-level await in handlers
Automatic handler registration from src/handlers — no more handler paths in config
New testing framework: run and snapshot-test your indexer programmatically, no live indexer needed
Experimental ClickHouse storage in dual mode with Postgres (supported on Envio Cloud dedicated plans)
HyperSync source improvements: server-side events replace polling, query cache (up to 90% egress reduction for self-hosters)
RPC source for real-time indexing with experimental WebSocket support
Experimental Solana support via slot handlers, plus block-handler-only indexers
pnpm no longer required — use npm, yarn, bun, or any package manager
Official Prometheus metrics endpoint and a cleaner TUI with live events/sec

Highlights

Effect API leaves experimental: createEffect without prefix
Required rateLimit option and per-call cache override via context.cache = false
Development Console shows detailed performance metrics (works with TUI disabled)
New getWhere.lt query helper
Internal cleanups: librarified config and in-memory table
