Integration for gqlgen about go-agent

[gwkline]

You can do this with middleware (at least partially). This example is for gin, but should apply for any server package as long as you properly set the NR agent in the context:

func (h *Handler) Graphql() gin.HandlerFunc {
	resolver := &resolver.Resolver{
		Repository: h.Repository,
	}
	c := generated.Config{Resolvers: resolver}
	serv := handler.New(generated.NewExecutableSchema(c))

	// ...
        // apply the middleware to each incoming request
	serv.AroundOperations(func(ctx context.Context, next graphql.OperationHandler) graphql.ResponseHandler {
		return h.newRelicMiddleware(ctx, next)
	})

	return func(c *gin.Context) {
		serv.ServeHTTP(c.Writer, c.Request)
	}
}

func (h *Handler) newRelicMiddleware(ctx context.Context, next graphql.OperationHandler) graphql.ResponseHandler {
	opContext := graphql.GetOperationContext(ctx)
	tx := newrelic.FromContext(ctx)
	// sets the transaction name, e.g. "query/userConnection"
	tx.SetName(fmt.Sprintf("%s/%s", opContext.Operation.Operation, opContext.Operation.Name))
	tx.AddAttribute("variables", opContext.Variables)
	
	return next(ctx)
}
