apollo-studio-tracing

This gem extends the GraphQL Ruby gem to add support for sending trace data to Apollo Studio. It is intended to be a full-featured replacement for the unmaintained apollo-tracing-ruby gem, and it is built HEAVILY from the work done within the Gusto apollo-federation-ruby gem as well an exploratory branch created here.

DISCLAIMER

Getting Started

1. Add use ApolloStudioTracing to your schema class.

2. Change your controller to add apollo_tracing_enabled: true to the execution context. Ensure that apollo_client_name and apollo_client_version are set as well, for proper client information in Studio:

     context = {
       apollo_client_name: request.headers["apollographql-client-name"],
       apollo_client_version: request.headers["apollographql-client-version"],
       apollo_tracing_enabled: Rails.env.production?,
     }
     # ...
   end
