I was thinking about something like:

  author.save()
 .then(() => {
    const article = new Article(db);
    article.name = "New name";
    article.author = author;
    return article.save(); // could be used to chain the next save
 })
 .then(() => {
    console.log("Both author and article saved successfully.");
 })
 .catch((error) => {
    console.error("rollback, no changes");
 });

but I confess I might have said that without having the same understanding of the problem as you so might be nonsense. it just happen that I decided to implement transactions this way in a side project of mine.
