In the hope of solving my issue regarding api secret key I am considering setting up a backend in order to manage some server logic for my app and maybe later a database.
I see mentionned in a lot of places Firebase for the database but as far as my understanding goes it can only manage some data and not server logic. Also in a managed app it seems that the tools that can be used are limited. (https://blog.expo.io/using-firebase-in-expo-e13844061832)
What is a recommended backend solution that you would advised for an expo app ? Do you know any good, up to date, documentation for this that include the security issues ? Is it possible to manage it with a managed app or does it have to be ejected ?
Thank you to help a newcomer to Expo finding its way.
