This examples integrates The Graph Client with NodeJS/TypeScript usage, with 2 Subgraphs that has similar GraphQL schemas. The goal of this example is to do requests to different subgraphs with dynamic context values

The example here is using the following tools/concepts:

• NodeJS + TypeScript
• The Graph Client CLI for generating artifacts
• Schema-stitching resolvers extension

      # ... rest of the fields
      chainId: String!
    }")
