Use when writing or editing config.yaml. Chain/contract structure, addresses, start_block, event selection, field_selection, custom event names, env vars, address_format, schema/output paths, YAML validation, and deprecated options.
Use when optimizing indexer speed or tuning sync performance. HyperSync, batch size, WebSocket realtime config, and preload optimization.
Use when indexing contracts deployed by factory contracts at runtime. contractRegister API, dynamic contract config (no address), async registration, and same-block event coverage.
Use when writing or editing event handlers. Handler registration, context API (entity CRUD, getWhere queries, chain, log), spread updates, indexer runtime API, and common pitfalls.
Use when deploying an indexer across multiple chains. Entity ID namespacing to avoid collisions, chain-specific configuration patterns, and the context.chain runtime API.
Use when needing transaction-level data in handlers. Configure field_selection to include transaction fields on events, and access via event.transaction. No native transaction handler — access through event handlers.

Symptom: Type errors after editing schema.graphql or config.yaml.
pnpm codegen
Always run codegen after any schema or config change.
Symptom: pnpm dev fails with connection refused or database errors.
docker info # check Docker is running
The indexer needs Docker for PostgreSQL. Start Docker and retry.
All env vars MUST use the ENVIO_ prefix. The hosted service only exposes variables with this prefix at runtime.
# WRONG
rpc:
- url: ${RPC_URL}
# CORRECT
rpc:
- url: ${ENVIO_RPC_URL}
Missing ENVIO_API_TOKEN: Required for HyperSync. Get an Envio API token at https://envio.dev/app/api-tokens, then set it in .env or shell environment.
"field not indexed" — getWhere only works on id and fields with @index in schema.graphql.
"entity is read-only" — Entities from context.Entity.get() are frozen. Spread to update: context.Entity.set({ ...entity, field: newValue }).
"Cannot find module 'envio'" — Run pnpm install.
Codegen output stale after config.yaml change — Run pnpm codegen again.
