Subgraph operations and indexing require careful local environment management, including synchronized codegen, controlled reindexing, and reliable deployment workflows to keep data consistent.
Run the codegen after editing the schema or mapping, then redeploy the subgraph to the local Graph node to apply changes.

Run codegen after editing schema.graphql or subgraph.yaml to synchronize TypeScript types and entity definitions, ensuring your AssemblyScript mappings reference accurate types before redeploying the subgraph to the local Graph node.
Perform controlled reindexing by versioning deployments with labels like v0.0.x or using graph remove to reset. This isolates reindexing to the targeted subgraph without impacting other services running on the local Graph node.
Deploy updated mappings to the local Graph node and verify the deployed addresses. This validation step ensures indexing remains accurate and configuration drift is prevented after applying mapping changes.
Subgraph indexing fails after schema modifications when codegen is not synchronized. You must run codegen to regenerate TypeScript types for your mappings before redeploying the subgraph to the local Graph node.
Yes, AssemblyScript is required to write subgraph mappings for the Graph Protocol. Codegen generates the necessary TypeScript types from your schema.graphql to support these mappings during indexing.
Use graph remove to completely reset a subgraph deployment, while versioned deployments like v0.0.x perform controlled reindexing. Choose graph remove when you need a full reset without preserving previous indexing state.
