Get Started with dfuse graphQL API over gRPC

This simple programme demonstrates how easy it is to query our graphQL API over gRPC.

• It uses our go client to retrieve a JWT that will then be used to create the gRPC credential.
• Create a gRPC connection.
• Instantiate a graphQL client.
• Write a simple graphQL query
• Execute the query and wait for response

Before you begin

• Visit golang gRPC prerequisites
• Then make sure that protoc is accessible from your $PATH

Get the source code

• git clone https://github.com/dfuse-io/example-graphql-grpc.git
