I want to get the node after a mutation. it’s my code:

        var updates = map[string]interface{}{
                "foo": "bar",
        }
        updates["uid"] = uid
	updates["metadata.update_time"] = time.Now().Unix()
	bs, err := json.Marshal(updates)
	if err != nil {
		return nil, err
	}

	_, err = dg.mutationJSON(ctx, bs)   // it's a mutation
	if err != nil {
		return nil, err
	}

	node, err = dg.queryByUID(ctx, uid) // after mutation, get the new node

Are there any way get the node after a mutation without query?

“Get the node” is actually “query for a node”, so either you query/get it, or you use your locally cached node (but then you don’t know if somebody else has changed it or not). So the simple answer would be “no”.

In the GraphQL API which is rewritten to DQL logic, it is doing a mutation and then a query. This also appeases the case when the query expects more data than the mutation. Example, if you link a new post to an existing user but in the response you want the query to return the authors other recent posts uids as well.
