hello, I am considering utilizing the ionic 2 storage facility for data persistence.
normally, we need a mechanism to check if a data is existing before initializing the data in persistant storage; something similar to this:
constructor(platform: Platform, private storage: Storage) {
platform.ready().then(() => {
...
//make sure the key does not exist in persistence
if(!this.storage.exist('key')){
this.storage.set('key', 'initial value');
};
...
};
without this, we just kept overwriting previous settings.
I read the docs about Storage, and did not find anything relevant…
anyone has any idea?
thanks
