You are not going to like my answer. As I already mentioned this before but...
Focus on the local development and leave production for the future. Your focus should be building and learning Wappler.
I actually dare you to decide your deployment and data migration methods today and stick to them when the day comes. I double dare you. You won't.
There are dozens of ways you can migrate a project to production including what Wappler provides and outside of Wappler. By the time you are ready two or three additional ones will be there waiting for you to take a decision. You can even hire people to do that for you if you don't feel confident when the time comes.
You are tying to eat the elephant in one bite 
You are not going to get the deployment and data migration wrong as long as you get your local app right. Just make sure your local backup procedure is solid because losing data is the only scary thing out there.
