no bad experiences. has decent performance. does a good job of separating client from server (put your business logic on the server and away from prying eyes).
If you are used to api calls from a client, then this doesn't do that sort of thing.
I am posting this since I am curious if anyone has any experience using it? I have done a few toy projects with it, and like it, but am not sure if it works well in production or if anyone has had any bad experiences.
