Overview

Package oteltracing provides a gqlgen middleware that adds otel tracing.

You can use it like:

srv := handler.New(es)
srv.Use(oteltracing.Tracer{})

If you would like spans for every field in the response you can enable FieldSpans:

srv := handler.New(es)
srv.Use(oteltracing.Tracer{FieldSpans: true})
