I’m not quite seeing what you mean. What you mind redoing the example above for my benefit? We have controllers that all the users actions are funnelled through. The top level functions in there are wrapped in transactions so in practice it’s not something you manually wrangle.
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 und…
I have a rule that I only async if it’s a requirement. In my case I can carry out all the steps in a single (simple) sync action. Our updates are optimistic so we update all the models immediately and mobx reflects that in the react components on the next frame.
The network request for the mutation is the only thing that’s running async. If that fails we crash the app immediately rather than trying to rollback bits in the frontend. I know that approach isn’t for everyone but it works well for us.
