I'm looking for guidance on best method to store user data without requiring 'registration'. Any help? Experience?

[macydj]

For example: I'd like to build a simple 'to do' list app that doesn't require users to register with an email and password. Asking the user to create an account seems like an unnecessary step for a simple app - at least from a users standpoint.

I haven't seen any demos that deal with user data that don't require registration. But I frequently encounter apps that are store your data and seeings WITHOUT requiring a sign up of any kind.

I imagine creating a random, unique userID and associating that with each to-do record in the database. This userID would be stored in a local storage variable, and used as the key for retrieving their own to-do items.

As I understand it the local storage items persistent for the life of the app? Is this correct? I get that if a user installs the app on a new device his/her list would be lost. Putting that aside, is this random userID feasible? What are best practices? Pitfalls? Thanks

Hello -

You can check our tutorial here for example, which shows main principles of ToDo app involving our cloud database: https://devcenter.appery.io/tutorials...

But you can modify it to use only Local Storage, the simple tutorial we also have here: https://devcenter.appery.io/tutorials...

Local Storage is a browser API, in hybrid app this APIs are accessible via WebView, more information about Local Storage you can search online e.g.: https://developer.mozilla.org/en/docs...

There are many JavaScript algorithms for generating random IDs or you can write your own or search for solution e.g.: http://stackoverflow.com/questions/10...
