This library provides OpenTelemetry (OTEL) instrumentation for gqlgen server requests.

Add the gqlgen_opentelemetry.Tracer extension to your server:

h := handler.NewDefaultServer(schema)
h.Use(gqlgen_opentelemetry.Tracer{
    Tracer: tracerProvider.Tracer("my-service"),
})

The following options are available on the extension:

IncludeVariables: Whether to include variables and their values in the trace span attributes. (Default: false)

Tracer: The OTEL tracer to use. If none is provided, a no-op tracer will be used.
