gqlgen

Overview ¶

Package gqlgen contains an implementation of a gqlgen tracer, and functions to construct and configure the tracer. The tracer can be passed to the gqlgen handler (see package github.com/99designs/gqlgen/handler)

Warning: Data obfuscation hasn't been implemented for graphql queries yet, any sensitive data in the query will be sent to Datadog as the resource name of the span. To ensure no sensitive data is included in your spans, always use parameterized graphql queries with sensitive data in variables.

Usage example:

import (
	"log"
	"net/http"

	"github.com/99designs/gqlgen/_examples/todo"
	"github.com/99designs/gqlgen/graphql/handler"

	"github.com/DataDog/dd-trace-go/v2/ddtrace/tracer"
	gqlgentrace "github.com/DataDog/dd-trace-go/v2/contrib/99designs/gqlgen"
)

func Example() {
	tracer.Start()
	defer tracer.Stop()

	t := gqlgentrace.NewTracer(
		gqlgentrace.WithAnalytics(true),
		gqlgentrace.WithService("todo.server"),
	)
	h := handler.NewDefaultServer(todo.NewExecutableSchema(todo.New()))
	h.Use(t)
	http.Handle("/query", h)
	log.Fatal(http.ListenAndServe(":8080", nil))
}
