I actually started developing xCloud apps 3 weeks ago, and was happy to find my way in 2 days.
I can tell you the documentation was not really helpful.
I’d like one guide to get started to have just a static app running. (it might sound stupid, but I just need static apps )
The apptemplate was the most helpful resource.
I really find it complicated the way the folder is organize, and I still don’t understand it. I’d like to have a strongly opinionated structure, meteor is good at that. You could have the same, describe every folder, and every files there, and what it should contain. (and then let people go crazy if they want, but a strong opinion for beginners is nice)
I also miss examples about the API usage, where I can get the groups of a user, if it is loggedin, where can I get the list of installed apps… Things like that.
But anyway, I found my way, and I created 2 apps, and thinking about a 3rd one, here is the list:
It is very alpha, but if you have some advices, let me know!
Also, I miss security considerations. There is quiet a lot on the documentation, which is good, but I have to admit, I’m pretty scared to add vulnerabilities to my cloud. I think the best (and I think it is the case) would be to make apps unharmful by default, and only if the app creator specify some flags, then the apps can turn powerful, and leak important data. (with static apps, I should be fine )
My 2 cents
