Subgraph Migration

What problem does it solve?

Migrating from TheGraph subgraphs to Envio HyperIndex can be complex due to differing config formats, schema representations, and handler patterns. This Skill provides a clear, end-to-end migration guide that aligns TheGraph concepts with HyperIndex equivalents to reduce risk and accelerate adoption.

Core Features & Use Cases

• Guides config migration from subgraph.yaml to HyperIndex config.yaml, including start_block and network mappings.
• Demonstrates schema conversion rules (Bytes/BigInt to Strings/BigInt, @entity removal, _id relationships, and @derivedFrom usage) with concrete examples.
• Covers handler migration and dynamic contract registration (contractRegister), including how to adapt event handlers and write stable, immutable entity updates.

Quick Start

Convert subgraph.yaml to HyperIndex config.yaml, migrate the GraphQL schema and TypeScript handlers, and register dynamic contracts to complete the migration.
